REGULAR MAINTENANCE
PARKING BRAKE
It is very dangerous that the parking brake does
not work properly.
Immediately stop operating the machine when you
feel abnormal conditions and carry out the adjustment
mentioned below.
1. Adjustment of the parking brake
(a) Move the brake handle up thus engaging the
parking brake. Check that the brake wire is tensed
fully. If brake wire is adjusted correctly, the spring
at the end of the wire next to the parking brake
shoe cover will lengthen approx. 10mm.

(b) If the parking brake is not engaging efficiently the
wire may be loose. Adjust the wire adjusting nuts on
each side of the metal brace to achieve desired
response from the parking brake handle.
(c) Tighten the wire adjusting nuts securely.
2. Checking and replacing parking brake shoe
If even after adjusting the parking brake wire, the
parking brake does not respond well, inspect the
parking brake pad and replace if necessary.
(a) Put the brake handle up and loosen the
parking brake wire with the adjuster nuts to
the maximum possible.
(b) Remove M3 screws x 3, seal / gasket
without damaging it and then the brake unit.

(c) Remove the snap ring and at the same time
the brake drum.
(d) Replace the brake shoe. Replace the seal
/ gasket too if necessary. Refit all parts tightly.
(e) Adjust the parking brake wire to achieve
adaquate response from the brake handle.
(f) Replace the parking brake wire if required.
(g) Tighten the wire adjusting nuts securely.
Note: The minimum usable thickness of the
brake pad is 1.5mm but it is recommended
to be replaced at 2mm. However, always
replace brake shoe if the adaquate
response is not achieved when engaging
the brake handle.
Note 2: The parking brake wire can be further
adjusted using the wire adjusting nuts
located underneath the feed swith near
the right turning control handle.
Note 3: It can be presumed that if the parking
brake shoe needs replacing so does
the transmission shoe. Inspect.
