BRAKE (= OPTION) ADJUSTMENT
BRAKE SHOE ADJUSTMENT
Check the thickness of the brake lining. Remove
both black plastic plugs (5), one on each wheel.
When the brake lining has been worn down to a
thickness of 1 mm (0.039 in) or less, the brake shoes
have to be replaced. After inspection and/or
replacement re-insert both plugs.
Brake shoe adjustment re-establishes the brake
lining-to-drum clearance and compensates for lining
wear.
Lift and support the compressor. Make sure that all
brakes are off (overrunbrake and hand brake lever).
The brake cables must be free from tension. Lock the
swivel cams of the wheel brake from the outside by
means of a pin ˘ 4 mm (4) through the hole as shown
in the Figure.
Turn the adjusting bolt (1) clockwise with a wrench
till the wheel locks up. Center the brake shoes by
actuating the parking brake several times.
Turn the adjusting bolt anti-clockwise until the wheel
is running free in direction of travel (approx. 1 full
turn of the adjusting bolt).
Check the position of the equalizer (see section
Brake cable adjustment, 6) with the parking brake
actuated.
Perpendicular position of equalizer = identical
clearance of wheel brakes.
Re-adjust the brake shoes, if necessary.
To test, slightly apply the parking brake and check
identical brake torque on left and right side.
Remove locking pin (4). Remove clearance from
brake cables.
Check all lock nuts (Brake cable adjustment, 2).

Before jacking up the compressor,
