WARNING! The following adjustment must be carried out
simultaneously on both brakes. Therefore, alternately adjust
on both LH brake and RH brake.
Inspect the following:
The parking brake lever: If it can be pulled further backwards than
90° (midway), using a traction of approximate 25 kg., the cable
needs to be adjusted.
The parking brake cable: When the parking brake is relieved, the
cable must be limp; otherwise it needs to be adjusted.
Correct length: When the brake is relieved the cable must be tight
and yet not stretched.
Lengthening/shortening of the parking brake cable is carried out by
adjusting the turnbuckle located inside the chassis.
Inspect the parking brake cables for possible wear or damages.
Replace worn or damaged parts.
1. Clean the area around air filter(s) and disconnect air hose from the

2. Hold one hand under the filter housing, and pull out the retainer
clip (A). The filter cartridge assembly will be pushed out by the

3. Clean the filter cartridge. Use water and an appropriate detergent
or compressed air.
4. Dry the parts and reinstall in the order shown. The O-ring should
be lightly lubricated with silicone grease before installation.
Lift the back of the COMMANDER from the ground. It is recommen-
ded to use two lifting jacks, placed underneath the axle. Make sure
the COMMANDER is stable and secured before carrying out any
adjustments.
