6 - Maintenance

250 hours service - Inspect parking brake (optional)

Inspect the following:
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.
Parking brake cable
Inspect the parking brake cables for possible wear or damages. Replace
worn or damaged parts.
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.

250 hours service - Air brake filters (optional)

1. Clean the area around air filter(s) and disconnect air hose from the
tractor.
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
springs inside the filter housing.
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.
±
WARNING! Never dismantle the filter without having the tractor
disconnected and pressure relieved.

250 hours service - Brake adjustment (optional)

Lift the back of the sprayer from the ground. It is recommended to use
two lifting jacks, placed underneath the axle. Make sure the sprayer is
stable and secured before carrying out any adjustments.
1. Loosen the 4 bolts at the brake connector (C) between the brake
arms. Also loosen the screw in each end of the brake connector
and the hand brake cable.
2. Adjust the nut (A) counterclockwise. Turn the nut 60° (1/6 turn) at
a time - alternately on both LH and RH brake. Continue adjustment
till resistance occurs when rotating the hub/wheel.
3. Turn the nut 60° (1/6 turn) clockwise to loosen brake. Hub/wheel should rotate freely now.
4. Tighten the brake connector (C) bolts again.
5. Tighten the hand brake cable again - See "250 hours service - Inspect parking brake (optional)" on page 90.
±
WARNING! The adjustment must be carried out simultaneously on both brakes. Therefore, alternately adjust on both
LH brake and RH brake.
