Unpacking

Due to modern mass production techniques, it is unlikely 

that your GMC Power Tool is faulty or that a part is 

missing. If you find anything wrong, do not operate the 

tool until the parts have been replaced or the fault has 

been rectified. Failure to do so could result in serious 

personal injury.

Assembly

Handle 

The handle of the AC40G model must be fitted in the 

following manner:
1. Remove the two grub screws from the plastic bag and 

fit into the screw holes in the handle locating tubes.

2.  Insert the two ends of the handle into the fixing holes.
3.  Tighten the screws to secure the handle in place.

Wheels 

1. To fit the wheels (12) first insert an axle pin through 

the wheel and then insert the spacer on the underside 

of the wheel. 

2. Fit the wheel assembly 

through the hole in the 

bracket under the tank. 

3. Fit the flat washer, split 

washer and nut. Tighten the 

nut from the underside of 

the wheel, and tap on the 

wheel cover.

4. Repeat for the second wheel.

Rubber feet 

Fit the rubber feet on the 

bracket on the front underside 

of the tank using the screws, 

washers and nuts supplied.

Oil 
WARNING.

 

The air compressor must be filled with oil 

before first use.

To prevent possible spillage of oil during transport, the 

compressor oil is supplied in a separate container. It must 

be added to the compressor before turning the compressor 

on. Failure to add the oil will cause non-repairable 

damage to the compressor and will void the warranty.
1. Remove the plastic oil filling cap (14) located on the 

top of the crank case of the compressor housing.

2. Use the oil supplied to fill the crank case until the oil 

level as seen in the oil level glass (16) is up to the mid 

point of the red circle.

3. Replace the oil filling cap (14). Ensure the cap is fully 

fitted and firmly in position.
