2.0 Preparation
2.1 Assembly
Assemble the received parts as follows. (See diagram 1.1)
1. Install the right tray on the base. 2. Tilt the motor up in the vertical position and tighten legs to the base frame (H). 3. Place the curtain rods in the trays together and hang the curtains up (see diagram
2.1).
Diagram 2.1: Assembly of curtains and curtain rods.
4. Fasten the belt grinder to the floor. 5. Roll the base under the front edge of the belt grinder.
6
6. Assemble the mounting arm (G) below the fork of the belt grind (K) with the
supplied screws. (See diagram 2.2)
Diagram 2.2: Assembly of curtains and curtain rods.
7. Lock the wheels under the base. 8. The magnetic cold water tap can be placed on the front of the belt grinder. 9. Pour 8-10 litres cold water in the cold water container located in the base. 10. Connect the motors to electricity. The machine is now ready.
7
2.2 The positions are open and closed See below how CGC 75 can be opened and closed.

3.0 Operation
The machine must be adjusted again for each tube dimension. Then the feed rate and direction are set.
3.1 Selection of support
For each tube dimension, the machine must be adjusted again. The tube dimension determines the support to be used in frame. Below the fork is mounted support roller (A) and Teflon support plate (B) respectively.
Diagram 3.1: The two supports. (A= Support roller B= Support Teflon)
The two scales located on the fork indicate where the support should be placed in relation to tube dimension. The support roller is used for the largest pipe dimensions larger than Ø25 and the support plate is used for the smaller tube dimensions smaller than Ø25.
Support table

3.2 Setting the fork
The fork height is set depending on the tube dimension Ø(inch). Loosen the lever and move the fork to the tube dimension, which is to be processed. The scale on the left is used with the help of the support Teflon. The scale to the right is used with the help of the support roller as seen below.
Diagram 3.2: The fork can slide up and down on the scales.
3.3 Putting the article in the machine
Place the article in the machine. Pull the propulsion jig to the open position (see diagram 2.4). Place the tube in the machine and adjust the pipe clamps so that they support it. Close the machine.
Remember for safety It is important to emphasize that when the tube is running, there is a chance that it can jump out of position. See diagram 3.3. For this reason, remember that the centre of the tube should never come past the centre of the support roller.
Diagram 3.3: Centre of centre for safety
10
3.4 Location of distance stop
The drive wheel should NEVER come in contact with the sanding belt. The distance stop is a safety precaution so that this can be avoided. For each pip dimension the distance stop must be adjusted, in order to avoid that the propulsion jig tilts down and comes in contact with the sanding belt. See the explanation in diagram 3.4. Here, the distance stop(1) is moved almost down to the plate(2). The distance stop between (1) and (2) must be 2-5 mm/0.1-0.2 inch - never less than 2 mm/0.1 inch.
Diagram 3.4: Direction of rotation of the drive gear (Q), Article (R) and Sanding belt
(S).
11
3.5 Selection of speed of belt grinder
The belt grinder is a two-speed belt grinder.
High speed is used for cleaning the pipes together with 60-80 grit sanding belts.
Low speed is used for finishing and polishing. After cleaning the pipes, a 180-400 grit sanding belt is used for finishing. The last process is polishing and here a 600-1200 grit sanding belt is used. Note that optimal polishing is achieved using as light a pressure as possible with the drive wheel. This applies especially during the final polishing stage.
Scantool Group offers a starter pack of the above sanding belts in grades adapted
to the processes: cleaning, finishing and polishing. Upon delivery, the standard
sanding belt is VSM K180 on the belt grinder. Please contact us for further
information. Now place the pipe between drive wheels, support and the contact wheel of the belt grinder with the sanding belt. Adjust the pipe clamps so that they support the pipe on both sides of the machine. The two motors on the belt grinder and propulsion unit can now be started at the desired speed. Start in the middle of the pipe to see the result of the set-up.
3.6 Feed speed and direction
Feed speed and direction, called feeding hereafter, are determined by the angle of the propulsion jig, as shown in grey below (diagram 3.5). The feed is changed by turning the propulsion jig a few degrees to one side or the other. The greater the angle, the greater the feed speed.
Diagram 3.5: Propulsion.
If you turn the lever (2) to the right, feeding can take place from the left and vice versa. In addition, the feed speed depends on how far the lever is turned out to either the right or
12
left side. Angles around 3-5 degrees will be sufficient for a good feed speed. It is necessary to experiment for each type of article. Turn off the machine and loosen the lever (1) on the front section to move the lever (2). Tighten lever 1 again and see how the machine runs now.
3.7 Operation of the centerless jig
1. Start the belt grinder and the centerless jig. If cooling is desired, open the cooling liquid tap a little bit and adjust the hose down against the sanding area. (Note that cooling must be turned off when the machine is not running for the sake of the sanding belt)
2. Check that the drive wheel on the Centerless jig is running in the direction of the
arrow. There is an arrow on the jig, which shows the correct direction corresponding to the arrow in diagram 3.4.
3. Carefully place the article in front of the rotating sanding belt and slowly lead the
centerless jig down against the article, which will rotate in the opposite direction of the drive wheel on the jig. Feed speed and direction are adjusted by turning the drive part to the right or left. See section 3.7.
3.10 Safety rules for stationary power tools.
Følg disse regler for at få det bedste resultat og den bedste udnyttelse af Deres nye maskine.
The good craftsman respects the tools with which he works. He knows they represent years of constantly improved design.
He also knows that they are dangerous if misused.
This is the theme of a new safe-use program for stationary
power tools. The safety rules are based on approved
practices in industrial and home shops
1. Know your power tool. Read the owner’s manual carefully. Learn its applications and limitations, as
well as the specific potential hazards
peculiar to this tool.
2. Keep guard in place and in working order.
3. Ground all tools. If tool is equipped with three-prong plug, it should be plugged into a three-hole
electrical receptacle. If an adapter is used to accommodate a two-prong receptacle, the adapter wire must be attached to a known
ground. Never remove the third
prong.
13
4. Remove adjusting keys and wrenches. Form
habit of checking to see that keys and adjusting wrenches is removed before turning it on.
5. Cluttered areas and benches invite accidents.
6. Avoid dangerous environment. Don’t use
power tools in damp or wet locations or expose them to rain. Keep your work area
well lighted.
6. Keep children away. All visitors should be kept in a safe distance from work area.
8. Make workshop kid proof with padlocks, master switches, or by removing starter keys.
9. Don’t force tool. It will do the job better and be safer at the rate for which it was designed.
.
10. Use right tool. Don’t force tool or attachment to do a job it was not designed for.
11. Wear proper apparel. Wear no loose clothing, gloves, neckties, rings,
bracelets, or other jewellery which may get caught in moving parts.
Non-slip footwear is recommended. Wear
protective hair covering to contain long hair.
12. Always use safety glasses. Also use face or dust mask if cutting operation is dusty. Everyday eyeglasses only have impact resistant
lenses. They are NOT safety glasses.
13. Secure works. Use clamps or vise to hold works, when practical. It’s safer than using your hands and it frees both hands to operate tool.
14. Don’t overreach.
Keep proper footing and balance at all times.
15. Maintain tools with care. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.
14
16. Disconnect tools before servicing and when changing accessories such as grinding wheels, polishing mops, grinding belts, blades, bits, cutters, etc.
17. Reduce the risk of unintentional starting. Make sure switch is in off position before plugging in.
18. Use recommended accessories. Consult owner’s manual for recommended accessories. Use of improper accessories may cause risk of injury to persons.
