Parking Brake
The parking brake is mounted on the output end of gearbox.
Wear can occur either by stretching of the brake cable, or wear
on the disc pads themselves, causing a reduction in efficiency.
Parking Brake Lever
To adjust the cable:-
• Release the parking brake (lever horizontal). Remove plastic
handgrip and slacken locking grub screw( B).
• Turn handle nut (C) to bring the pin (D) central in the slot.
Retighten grub screw and replace plastic grip.

Brake Caliper
To adjust the brake caliper:-
• Slacken the locknuts (E) on the brake cable (F). Tighten the
lower nut until the linings contact the brake disc (G) and
prevent the disc from turning easily.
• Slacken the nut (E) off until the brake disc (G) turns freely
without any friction on the brake disc. Tighten the locknuts
(E) and check the brake disc (G) still turns freely.
Any further adjustment should be done at the parking brake
lever.
Parking Brake Test
When adjusted correctly the parking brake should hold the
vehicle at full engine revs in 4th gear. Test as follows:-
• Ensure all personnel are clear of the area and the area is free
of obstructions.
• Apply parking brake.
• Select Forward and 4th Gear.
• Increase engine speed gradually up to maximum R.P.M
If vehicle moves abort test immediately re-check adjustment.

Before adjusting the parking brake make sure that the
machine is on level ground. Chock all four wheels to
prevent machine moving. Set battery isolator to OFF.
