r Adjust the air pressure as much as the lowestpossible according the length of fastener andthe hardness of work-piece.

MODEL IDENTIFICATION

CONTACT TRIPThe common operating procedure on “ContactTrip” tools is for the operator to contact the workto actuate the trip mechanism while keeping thetrigger pulled, thus driving a fastener each timethe work is contacted. This will allow rapidfastener placement on many jobs, such assheathing, decking and pallet assembly.All pneumatic tools are subject to recoil whendriving fasteners. The tool may bounce, releasingthe trip, and if unintentionally allowed to recontactthe work surface with the trigger still actuated(finger still holding trigger pulled) an unwantedsecond fastener will be driven.

CONTACT TRIPIdentified by BLACK TRIGGER.

SEQUENTIAL TRIPThe Sequential Trip requires the operator to holdthe tool against the work before pulling the trigger.This makes accurate fastener placement easier,for instance on framing, toe nailing and cratingapplications. The Sequential Trip allows exactfastener location without the possibility of drivinga second fastener on recoil, as described under“Contact Trip”.The Sequential Trip Tool has a positive safetyadvantage because it will not accidentally drive afastener if the tool is contacted against the work-or anything else-while the operator is holding thetrigger pulled.

5. MAINTAIN FORPERFORMANCE

q DO NOT FIRE THE STAPLER WHEN IT ISEMPTY

w USE A 3-PIECE AIRSETFailure to use a 3-piece airset allows themoisture and dirt inside compressor to passinto the tool directly. This causes rust andwear, and results in a poor operatingperformance. The hose length between airsetand tool should be no longer than 5 m since alonger length results in a reduction in airpressure.

e USE RECOMMENDED OILThe velocite or turbine oil should be used tolubricate the tool. Upon completion ofoperations, place 2 or 3 drops of oil into the airplug inlet with the jet oiler. (Recommended Oil: ISO VG32)

r INSPECT AND MAINTAIN DAILY ORBEFORE OPERATION

Disconnect air supply and empty themagazine when inspecting or maintaining thetool.

(1) Drain air line filter and compressor(2) Keep lubricator filled in air 3-pieces set(3) Clean filter element of air 3-pieces set(4) Tighten all screws(5) Keep contact arm moving smoothly

6. STORING

q When not in use for an extended period, applya thin coat of the lubricant to the steel parts toavoid rust.

w Do not store the tool in a cold weatherenvironment. Keep the tool in a warm area.

e When not in use, the tool should be stored in awarm and dry place. Keep out of reach ofchildren.

r All quality tools will eventually require servicingor replacement of parts because of wear fromthe normal use.

7. TROUBLESHOOTING/REPAIRS

The troubleshooting and/or repairs shall becarried out only by the MAX CO., LTD. authoriseddistributors or by other specialists.

Supplement to the operating instructionAccording to the European Norm EN 792-13 theregulation is valid from 01.01.2001 that allfastener driving tools with contact actuation mustbe marked with the symbol “Do not use onscaffoldings, ladders” and they shall not be usedfor specific application for example:
