Fuel and oil mixtureThe engine of the Hedge Trimmer is a high-efficiency two-stroke engine. –It is run with a mixture of fuel and two-stroke engine oil. The engine is designed for unleaded regular fuel with a min. octane value of 91 RON. In case no such fuel is available, you can use fuel with a higher octane value. This will not damage the engine, but may cause poor operating behaviour. A similar situation will arise from the use of leaded fuel. To obtain optimum engine operation and to protect your health and the environment, only unleaded fuel should be used!For lubricating the engine use a two-stroke engine oil (quality grade: TSC-3), –which is added to the fuel. The engine has been designed for use with MAKITA two-stroke engine oil and a mixture ratio of 50:1 only to protect the environment. In addition, a long service life and a reliable operation with a minimum emission of exhaust gases is guaranteed. It is absolutely essential to observe a mixture ratio of 50:1 (MAKITA 2-stroke engine oil), otherwise the reliable function of the Hedge Trimmer cannot be guaranteed.The correct mixture ratio: –Mix 50 parts gasoline with 1 part MAKITA 2-stroke engine oil (See table on the right).

NOTE: For preparing the fuel-oil mixture, first mix the entire oil quantity with half of the fuel required. In an approved can which meets of exceeds all local code standards, then add the remaining fuel. Thoroughly shake the mixture before filling it into the Hedge Trimmer’s tank. It is not wise to add more engine oil than specified to ensure safe operation. It will only result in a higher production of combustion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the muffler. In addition, the fuel consumption will rise and the performance will decrease.

Handling petroleum productsUtmost care is required when handling fuel. Fuel may contain substances similar to solvents. Refuel either in a well ventilated area or outdoors. Do not inhale fuel vapors, avoid any contact of fuel or oil with your skin.If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desiccate.Various skin diseases may result. In addition, allergic reactions are known to occur.Eyes can be irritated by contact with oil, fuel etc.If oil, fuel, etc., comes into your eyes, immediately wash them with clear water. If your eyes are still irritated, see a doctor immediately!

Never run the engine in enclosed rooms (Risk of gas poisoning). Carbon monoxide is an odorless gas.All protective installations and guards supplied with the machine must be –used during operation.Never operate the engine with a faulty exhaust muffler or if it is missing. –Use the Hedge Trimmer only in good light and visibility. –During the winter season beware of slippery or wet areas, ice and snow. (Risk of slipping.) Always ensure a safe footing.Never stand on a ladder and run the Hedge Trimmer. Keep both feet on the –ground.Never climb up the trees with the Hedge Trimmer to perform cutting –operation.Never work on unstable surfaces. –Remove sand, stone, nails, wire, etc. found within the working area. –Foreign objects may damage the cutting blades.Before commencing cutting, the cutting blades must have reached full –working speed.Always hold the Hedge Trimmer firmly with both hands on the handles only. –The right hand grips the front handle of model HTR7610. –This is the way to safely operate the machine.Use a firm grip with thumbs and fingers encircling the handles. –When you release the throttle, it takes a few moments before the cutting –blades stop.The Hedge Trimmer must not be used for cutting with fast idle. The cutting –speed cannot be adjusted with the throttle control in fast idle position.When cutting a hedge, the machine should be held so that the blades form a –15-30° angle with the cutting line.If the Hedge Trimmer is used with circular movements against the edge of the –hedge, the twigs will be thrown directly to the ground.At vertical cutting, the Hedge Trimmer is used with circular pendulation, –swinging up and down close to the hedge.Pay special attention when cutting hedges which are laid out a long a wire- –fence and have grown through the fence. The blade must not contact the fence, otherwise the blades may be destroyed.Do not use the Hedge Trimmer continuously for a long time. It is normal to –take a break of 10 to 20 minutes after every 50 minutes operation.Should the cutting blades hit stones or other hard objects, immediately switch –off the engine and inspect the cutting blades for damage. Replace damaged blades before re-commencing work.The engine must be switched off immediately in case of any engine problems. –Operate the Hedge Trimmer with as little noise and contamination as –possible. In particular check the correct setting of the carburetor and the fuel/oil ratio.Do not attempt to remove jammed cut material when blades are running. Put –unit down, turn it off, and remove necessary cuttings.

12

MAINTENANCE INSTRUCTIONSTurn off the engine and remove the spark plug connector when replacing or sharpening cutting tools, also when cleaning the cutter or cutting –device or carrying out any maintenance.Never straighten or weld a damaged cutting blade. –Inspect the cutting blades with the engine switched off at short, regular intervals for damage. –(Detection of hairline cracks by means of tapping-noise test.) Beware the teeth are sharp.Clean the Hedge Trimmer at regular intervals and check that all screw and nuts are well tightened. –Never service or store the Hedge Trimmer in the vicinity of naked flames to avoid fires. –Always wear leather gloves when handling or sharpening the blades as they are sharp. –

Blade sharpeningIf the edges are rounded and do not cut well any more, grind off only the shaded portions. Do not grind the contact surfaces (sliding surfaces) of the top and bottom edges.

Before grinding, be sure to secure the blade firmly and –switch off the engine and remove the spark plug cap.

Wear gloves, protective glasses, etc. –

An edge ground too much at a time or ground many times –will lose its hardened layer. It becomes rounded and dull very quickly in use.

Blade adjustmentThe blades will wear with long use. When you find that trimming is not as good as when the blades were new, adjust them as follows1. Turn nut 1 loose.2. Screw 2 in with the driver lightly till it stops turning, and

then screw it back one quarter.3. Turn nut 1 tight, holding screw 2 at the same time with a

driver.4. Lubricate the blades after adjustments above with light oil.5. Start the engine and operate the engine throttle on and off

for a minute.6. Stop the engine and touch the blades with your hand. If they are warm enough for you to keep your hand on, then you have made the

proper adjustment. If they are too hot for you to keep touching, give screw 2 a little more turnback and repeat 5 to see if they are properly adjusted.

NOTE: Never fail to stop the engine before making the adjustment. The blades have a slot around screw 2. In case you find dust in the end of any of the slots, clean it.

NOTE: For enough time of blade stop (EN774), be sure to make the blade adjustment before operation.

Checking and adjusting the idling speedThe cutting blade should not when the control lever is fully released.

Idle speed should be set to 2,600 rpm. –If necessary, correct it by means of the idle screw (the cutting blade must not run when the engine is on idle).

Clockwise : for faster rate of revolution• Counter-clockwise : for slower rate of revolution • Check that there is sufficient difference between idling and clutch engagement speed to ensure that the cutting tool is at a standstill while the engine is idling. (If necessary, reduce idling speed.) If the tool still continues to run under the idling conditions, consult your nearest authorised service agent.The clutch should engage at minimum 3,250 rpm.• Check the functioning of the STOP Switch, the lock-off lever, the control • lever, and the lock button.

Cleaning of air cleaner - Every 8 hours (Daily)Remove the air cleaner cover. –Take out the sponge element, wash it in lukewarm water and dry it –completely.After cleaning, put back the sponge element and the air cleaner cover. –

NOTE: If there is excessive dust or dirt adhering to the air cleaner, clean it every day. A clogged air cleaner may make it difficult or impossible to start the engine or increase the engine rotation speed which could cause damage.

Checking the spark plug - Every 8 hours (Daily)Only use the supplied universal wrench to remove or to install the spark plug. –The gap between the two electrodes of the spark plug should be 0.6 to –0.7 mm. If the gap is too wide or too narrow, adjust it. If the spark plug is clogged with carbon or fouled, clean it thoroughly or replace it. Use an exact replacement.

Supply of grease and lubricantSupply grease to the gear case through the grease hole every 10 to 20 hours. –(Shell alvania No.3 or equivalent)

0.6 - 0.7 mm

Campuran bensin dan oliMesin dari Pemangkas Pagar ini adalah mesin dua tak berefisiensi tinggi. –Mesin ini berjalan dengan campuran bensin dan oli mesin dua-tak. Mesin ini dirancang untuk bensin tanpa timbal biasa dengan nilai oktan minimum 91 ROZ. Jika bensin jenis tersebut tidak tersedia, Anda dapat menggunakan bensin dengan oktan lebih tinggi. Hal ini tidak akan merusak mesin, tetapi dapat menyebabkan laku kerja yang buruk. Situasi yang sama dapat terjadi dari penggunaan bensin bertimbal. Untuk mendapatkan manfaat mesin yang optimal dan untuk melindungi kesehatan dan lingkungan Anda, gunakan hanya bensin tanpa timbal!Untuk pelumasan mesin, gunakan oli mesin dua-tak (tingkat mutu: TSC-3), –yang dicampur ke dalam bensin. Mesin ini dirancang untuk digunakan dengan oli mesin dua-tak MAKITA dan gunakan rasio campuran 50:1 untuk melindungi lingkungan. Sebagai tambahan, kami menjamin usia pakai yang panjang dan pemakaian yang handal dengan emisi gas buang minimum. Sangatlah penting untuk mematuhi rasio campuran 50:1 (oli mesin 2-tak MAKITA), jika tidak penggunaan Pemangkas Pagar yang handal tidak dapat terjamin.Rasio campuran yang tepat –Bensin : oli mesin 2-tak MAKITA asli = 50 : 1 atau Bensin : oli mesin 2-tak buatan pabrikan lain = disarankan 25 : 1

CATATAN: Untuk menyiapkan campuran bensin-oli, pertama-tama campur seluruh bagian oli dengan setengah bensin yang dibutuhkan. Di dalam kaleng yang baik yang memenuhi atau melampaui standard lokal, tambahkan sisa bensin yang ada. Kocok campuran sebelum memasukkannya ke dalam tangki Pemangkas Pagar. Sangatlah tidak bijaksana untuk menambah oli mesin selain yang disarankan untuk memastikan pemakaian yang aman. Hal itu hanya akan menambah residu pembakaran yang akan mencemarkan lingkungan dan menyumbat jalur pembuangan dalam silinder serta knalpot. Sebagai tambahan, penggunaan bensin akan bertambah dan kinerja akan menurun.

Menangani produk minyakAnda harus sangat berhati-hati dalam menangani bensin. Bensin dapat mengandung zat yang serupa dengan solven. Lakukan pengisian kembali di area yang berventilasi baik atau di luar ruangan.Jangan menghirup uap bensin, hindari kontak antara kulit Anda dan bensin atau oli.Jika kulit Anda bersentuhan dengan zat-zat tersebut berulang-kali dan untuk jangka-waktu lama, kulit akan mengering.Penyakit kulit mungkin dapat timbul. Sebagai tambahan, reaksi alergi diketahui dapat muncul.Mata dapat teriritasi karena kontak dengan oli, bensin, dll.Jika oli, bensin, dll. bersentuhan dengan mata Anda, basuh segera dengan air bersih. Jika mata Anda masih teriritasi, segera kunjungi dokter!

Hỗn hợp nhiên liêu và nhớtĐộng cơ của máy cắt hàng rào là động cơ hai thì công suất cao. –Động cơ chạy với hỗn hợp nhiên liệu và nhớt động cơ hai thì. Động cơ được thiết kế cho nhiên liệu thông thường không chì với giá trị octan nhỏ nhất là 91 RON. Trong trường hợp không có nhiên liệu trên, bạn có thể sử dụng nhiên liệu với giá trị octan cao hơn. Sử dụng nhiên liệu này không làm ảnh hưởng đến động cơ, nhưng có thể gây ra động thái vận hành kém hiệu quả. Việc sử dụng nhiên liệu có chì cũng cho kết quả tương tự như vậy. Để đạt được khả năng vận hành động cơ tối ưu và để bảo vệ sức khỏe và môi trường, chỉ nên sử dụng nhiên liệu không chì!Để bôi trơn động cơ, sử dụng nhớt máy động cơ hai thì (mức chất lượng: –TSC – 3), được dùng để bổ sung vào nhiên liệu. Động cơ đã được thiết kế cho việc sử dụng với nhớt động cơ hai thì MAKITA và tỉ lệ hỗn hợp 50:1 để bảo vệ môi trường. Ngoài ra, việc sử dụng loại nhiên liệu trên cũng đảm bảo cho thiết bị có tuổi thọ lâu bền, vận hành tin cầy với mức khí thải thấp nhất. Tuân thủ tỉ lệ 50: 1 là tuyệt đối cần thiết (dầu động cơ 2 thì MAKITA), nếu không chức năng đáng tin cậy của máy cắt hàng rào sẽ không được đảm bảo.Tỉ lệ hỗn hợp phù hợp: –Trộn 50 phần xăng với 1 phần nhớt động cơ hai thì MAKITA (xem bảng bên phải)

CHÚ Ý: Để chuẩn bị hỗn hợp nhiên liệu – nhớt, trước tiên trộn toàn bộ lượng nhớt với một nửa nhiên liệu cần thiết. Đựng nhiên liệu trong bình chứa đạt các tiêu chuẩn của địa phương, sau đó pha nhiên liệu còn lại. Lắc kỹ hỗn hợp trước khi đổ nó vào bình chứa nhiên liệu của máy cắt hàng rào. Không nên pha nhiều nhớt máy hơn quy định để đảm bảo vận hành an toàn. Pha nhiều nhớt máy hơn mức quy định chỉ tạo ra nhiều chất dư trong quá trình đốt cháy hơn, điều này sẽ làm ô nhiễm môi trường và làm tắc đường dẫn khí thải trong xi lanh cũng như bộ tiêu âm. Hơn nữa, làm tiêu thụ nhiên liệu nhiều hơn và giảm hiệu suất.

Xử lý các sản phẩm dầu hỏaCần hết sức cẩn thận khi xử lý nhiên liệu. Nhiên liệu chứa các chất tương tự như các dung môi. Nên nạp nhiên liệu ở nơi được thông gió tốt hoặc ở ngoài trời. Không hít vào hơi nhiên liệu, tránh để da tiếp xúc với nhiên liệu hoặc dầu.Nếu da của bạn tiếp xúc với những chất này thường xuyên và trong thời gian kéo dài, da sẽ trở nên khô.Nhiều bệnh về da cũng có thể phát sinh. Hơn nữa, cũng có thể gây nên các phản ứng dị ứng.Mắt có thể bị kích thích do tiếp xúc với dầu, nhiên liệu.Nếu dầu, nhiên liệu vào mắt, cần nhanh chóng rửa bằng nước sạch. Nếu mắt vẫn bị kích thích, cần gặp bác sĩ ngay!

KHỞI ĐỘNG MÁYDi chuyển máy cách điểm nạp liệu ít nhất 3 mét. Đặt máy cắt hàng rào lên mặt đất sạch, và đảm bảo dụng cụ cắt không tiếp xúc với mặt đất hoặc bất kỳ vật nào khác. Khởi động lạnh (khi máy nguội hoặc nó ngừng hoạt động được hơn 5 phút hoặc khi nhiên liệu được nạp vào máy.

1. Ấn bộ chuyển mạch I-O (1) về vị trí “I”.2. Ấn nhẹ lên bơm mồi (2) liên tục (7 đến 10 lần ) cho đến khi nhiên liệu vào

bơm mồi.3. Di chuyển cần nắp nghẽn hơi (3) tới vị trí “START”.4. Giữ máy chặt để bạn không bị mất khả năng điều khiển trong khi khởi động

máy. Nếu không giữ chặt một cách thích hợp, máy có thể giật làm bạn mất thăng bằng hoặc làm vung dao cắt bị nghẽn hoặc chém vào cơ thể của bạn.

5. Kéo cần khởi động khoảng 10 đến 15 cm, và kiểm tra vị trí áp suất.6. Kéo mạnh khi cảm thấy có áp suất và khởi động máy.7. Khi động cơ khởi động, đẩy cần nắp nghẽn hơi về vị trí “Run”.

Chú ý là cần nắp nghẽn hơi sẽ trở về vị trí “Run” một cách tự động khi đòn bẩy tiết lưu được vận hành và tiết lưu được mở.

8. Chạy máy khoảng một phút ở vận tốc trung bình trước khi chạy vận tốc tối đa.

CHÚ Ý: - Nếu tay cầm bộ khởi động được kéo liên tục khi cần nắp nghẽn hơi vẫn ở vị trí “Start”, máy sẽ không khởi động được dễ dàng do nạp nhiên liêu thừa.

- Trong trường hợp nạp thừa nhiên liêu, bạn phải tháo bugi ra và kéo cần khởi động từ để khử nhiên liêu dư. Hơn nữa, phải làm khô phần điên cực của bugi.

Khởi động nóng: (Khởi động lại ngay sau khi động cơ ngừng hoạt động) Khi khởi động một động cơ nóng, trước tiên thử trình tự các bước trên: 1, 4, 5, 6. Nếu máy không khởi động, lặp lại các bước trên từ 1-8.

CHÚ Ý: Không kéo dây thừng khởi động tới mức tối đa và không để cần khởi động co về một cách không kiểm soát, phải đảm bảo cho cần điều khiển co về một cách từ từ.

NGỪNG MÁY1. Nhả đòn bẩy tiết lưu hoàn toàn.2. Đẩy bộ chuyển mạch NGỪNG (bộ chuyển mạch tắt/

mở) về vị trí “O”, tốc độ quay của máy sẽ trở nên chậm và máy sẽ ngừng hoạt động.

HƯỚNG DẪN BẢO DƯỠNGTắt máy và tháo bộ nối bugi khi thay thế hoặc mài sắc các dụng cụ cắt, và khi làm sạch dao cắt hoặc thiết bị cắt hoặc thực hiện bất kỳ công –việc bảo dưỡng nào.Không được nới thẳng hoặc hàn một dao cắt bị hỏng. –Kiểm tra các dao cắt khi đã tắt máy được một lúc, kiểm tra định kỳ xem có bị hư hại gì không. –Lau sạch máy cắt hàng rào định kỳ và kiểm tra toàn bộ các vít và đai ốc đã được vặn chặt hay chưa. –Không bảo dưỡng hoặc bảo quản máy cắt hàng rào trong khu vực có ngọn lửa trần để tránh cháy nổ. –Luôn đeo găng tay bằng da khi xử lý hoặc mài sắc dào khi chúng sắc. –

Mài sắc daoNếu lưỡi dao bị cùn và không cắt tốt nữa, cần phải mài các vùng bị cùng. Không mài các bề mặt tiếp xúc (bề mặt trượt) của các lưỡi dao trên và dưới.

Trước khi mài, nhớ giữ chặt lưỡi dao, tắt máy và tháo lắp –bugi.Đeo găng tay, kính bảo vệ,… –Một lưỡi dao được mài quá nhiều một lần hoặc mài nhiều –lần sẽ mất lớp tôi cứng. Nó sẽ trở nên nhẵn và cùn nhanh trong quá trình sử dụng.

Điều chỉnh daoCác lưỡi dao sẽ bị mài mòn trong quá trình sử dụng lâu dài. Khi bạn thấy việc cắt không còn tốt như khi dao còn mới, điều chỉnh chúng như sau.1. Vặn đai ốc 1 lỏng.2. Bắt vít 2 bằng cần siết một cách nhẹ nhàng cho đến khi nó

ngừng quay, và sau đó vặn ngược lại một phần tư vòng.3. Vặn đai ốc 1 chặt, đồng thời bắt vít 2 bằng một cần siết.4. Bôi trơn các dao sau khi thực hiện các điều chỉnh trên với

dầu nhẹ.5. Khởi động máy và vận hành tiết lưu máy đóng và mở

khoảng một phút.6. Ngừng hoạt động động cơ và dùng tay sờ vào các dao. Nếu chúng đủ ấm để bạn có thể sờ tay vào, khi đó bạn đã điều chỉnh đúng. Nếu

chúng quá nóng và bạn không thể sờ vào được, bạn vặn vít 2 ngược lại một chút và làm lại bước 5 như trên để xem các dao đã được điều chỉnh đúng hay chưa.

CHÚ Ý: Phải ngừng máy trước khi điều chỉnh. Các dao có một rãnh xung quanh vít 2. Trong trường hợp bạn thấy có bụi ở cuối bất kỳ một rãnh nào, hãy lau sạch nó.

CHÚ Ý: Để cho dao ngừng quay đủ một thời gian nhất định (EN 774), nhớ điều chỉnh dao trước khi vận hành.

Kiểm tra và điều chỉnh tốc độ chạy khôngDao cắt không nên được chạy không khi cần điều khiển đã được nhả hoàn toàn.

Tốc độ chạy không nên được thiết lập về mức 2.600 rpm. –Nếu cần thiết, điều chỉnh nó bằng vít điều chỉnh chạy không tải (dao cắt không được chạy khi máy đang ở chế độ không tải).

Chiều kim đồng hồ: để điều chỉnh tốc độ quay nhanh hơn.• Chiều ngược kim đồng hồ: đề điều chỉnh tốc độ quay chậm hơn. • Kiểm tra xem có đủ sự chênh lệch giữa tốc độ vào khớp ly hợp và tốc độ chạy không tải để đảm bảo dụng cụ cắt đứng yên trong khi máy đang ở chế độ không tải. (nếu cần thiết, giảm tốc độ chạy không tải.). Nếu dụng cụ cắt tiếp tục chạy trong điều kiện không tải, cần tham khảo ý kiến với đại lý bảo dưỡng ủy quyền gần nhất của bạn.Ly hợp nên vào khớp tối thiểu 3.250 rpm.• Kiểm tra chức năng của bộ chuyển mạch NGỪNG, cần khóa, cần điều • khiển, và nút khóa.

Lau sạch bộ lọc khí – 8 tiếng một lần (hàng ngày)Tháo nắp bộ lọc khí. –Lấy bộ phận cao su xốp ra ngoài, rửa nó trong nước ấm và để khô hoàn –toàn.Sau khi làm sạch, lắp lại bộ phận cao su xốp và nắp bộ lọc khí. –

CHÚ Ý: Nếu có quá nhiều bụi và bẩn dính vào bộ lọc khí, cần làm sạch nó hàng ngày. Bộ lọc khí bị kẹt làm cho máy khó hoặc không thể khởi động được hoặc làm tăng tốc độ quay của máy và dẫn đến làm hỏng máy.

Kiểm tra bugi – 8 giờ một lần (hàng ngày)Chỉ sử dụng chìa vặn vít thông dụng được cung cấp để tháo và lắp bugi. –Khe hở giữa hai điện cực của bugi nên được duy trì ở mức 0,6 - 0,7 mm. –Nếu khe hở quá lớn hoặc quá hẹp, điều chỉnh nó. Nếu bugi bị kẹt với các bon hoặc bị bẩn, cần làm sạch bugi thật kỹ càng hoặc thay thế bugi mới. Thay thế đúng chủng loại.

Tra mỡ hoặc dầu bôi trơnTra mỡ cho hộp số thông qua lỗ tra mỡ sau 10-20 giờ. (Sử dụng loại Shell –alvania Số.3 hoặc tương đương).

Đầu hút trong bình nhiên liêuBộ lọc phớt (1) của đầu hút được sử dụng để lọc nhiên liệu cần thiết cho bộ –chế hòa khí.Kiểm tra định kỳ bằng mắt thường đối với bộ lọc phớt. Đối với mục đích này, –mở nắp thùng nhiên liệu, sử dụng một dây thép có móc và kéo đầu hút qua chỗ mở bình nhiên liệu. Bộ lọc đã bị cứng, bẩn hoặc bị két thì cần phải thay thế.Nạp liệu không đủ có thể làm tốc độ cho phép tối đa cho phép bị vượt quá. –Do vậy việc thay thế bộ lọc phớt ít nhất ba tháng một lần là điều quan trọng để đảm bảo cung cấp nhiên liệu thỏa mãn cho bộ chế hòa khí.

Làm sạch lỗ xả bộ tiêu âmKiểm tra lỗ xả bộ tiêu âm (2) một cách định kỳ. –Lỗ xả bị tắc bởi cặn các bon, cạo bỏ cặn này ra ngoài một cách cẩn thận –bằng một dụng cụ thích hợp. Không để cho các bon rơi vào các lỗ máy.

Bất kỳ công việc bảo dưỡng hay điều chỉnh nào không được đề cập hoặc mô tả trong sách quy trình hướng dẫn này đều phải được thực hiện bởi Đại lý bảo dưỡng ủy quyền.

Kiểm tra và bảo dưỡng hàng ngàyĐể đảm bảo cho máy có được tuổi thọ lâu dài và tránh làm hư hại thiết bị, cần phải thực hiện các công việc bảo dưỡng sau đây một cách định kỳ.

Trước khi vận hành, kiểm tra máy xem các vít có bị lỏng hoặc thiếu sót bộ phận nào hay không. Cần đặc biệt chú ý tới độ chặt của các vít –dao cắt.Trước khi vận hành, luôn luôn kiểm tra xem đường dẫn khí làm mát và các cánh xi lanh có bị kẹt hay không. Lau sạch các bộ phận này nếu –cần thiết.Thực hiện các công việc sau đây hàng ngày sau khi sử dụng: –

Lau sạch bên ngoài máy cắt hàng rào và kiểm tra xem có bị hư hại gì hay không.• Lau sạch bộ lọc khí. Khi làm việc dưới các điều kiện hết sức bụi bặm, phải làm sạch bộ lọc vài lần một ngày.• Kiểm tra các dao xem có bị hư hại hay không và đảm bảo chúng phải được lắp chặt.•
