lock nut, then tightening the adjustment
nut.
Tighten the adjustment nut until the
brake lining contacts the friction surface
of the disc.

Too narrow clearance gap between the brake disc and brake
lining may cause heat generation and fire.
3) Loosen the adjustment nut to adjust the
clearance gap between the brake disc
and brake lining to about 0.2 mm (0.0079
in).
4) Securely place the jack beneath the jack-
up point of the front left/right frame area,
and then raise it until both tires lift off the
ground.
5) Check that the disc rotates freely.
6) Fully tighten the lock nut while holding
the adjustment nut in place.
7) With the brake pedal released, obtain a
play of 1.0 mm (0.039 in) at the
connection of the pedal and inner wire.
8) Use a wrench to loosen the lock nut and
tighten it after making the adjustment
with the adjustment bolt.
9) Drive, and then check the following.
Make sure that heat is not generated in
the brake area.

<Break-in of Brakes>

brakes is low.
While driving, lightly operate the brakes to
break in the contact areas.
11-9 Air-bleeding from fuel
Since this machine has equipped the
automatic air bleeder, the air-bleeding
operation is unnecessary.
* Always use the air-bleeding valve with
the fully open position.
If it is used in the closed position, it will
become the cause of the engine stop.
