250 Hours Service - Inspect Parking Brake

Inspect the following:
Parking brake lever
If it can be pulled further backwards than 90° (midway), using a traction
of approximately 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 frame.

250 Hours Service - Brake Adjustment

Lift the rear of the sprayer from the ground. It is recommended to use
two lifting jacks, which are placed under the wheel 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) counter-clockwise. Turn the nut 60° (1/6 turn) at
a time - alternately between left and right brake. Continue the
adjustment, until resistance occurs when rotating the hub/wheel
by hand.
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 parking brake cable again (see section above).

250 Hours Service - Hydraulic Brakes

Apply brakes to full pressure and inspect brake lines for damages or leaks. Replace damaged parts. If the hydraulic brake lines
have been dismantled, the hydraulic circuit must be vented afterwards:
1. Loosen the brake hose at both brake cylinders.
2. Apply the brake, until oil without air bubbles comes out.
3. Tighten the brake hose, before relieving the brake again.
±
WARNING! Always vent the circuit, if the hydraulic brake lines have been dismantled.
