ing

travel
road well
and
steer the machine
properly.

12.9.3 PRECAUTIONS WHEN TRAVELING UP OR DOWN
HILLS
Use
engine as a brake
When
going downhill, shift
gear shift
lever into low speed to run
engine at slow speed and travel down slope using the engine as
a
brake.
Never coast down slope with
the steering and directional lever
in the N (neutral) position
or with the inching pedal depressed.
Braking when traveling downhill
While descending a slope using the engine as a
brake, also apply
the brakes.
Failure to brake may result in
overrunning, causing engine
trouble.
12.9.4 PRECAUTIONS ON SLOPES
Be careful of fuel level
If the fuel level in the
fuel tank becomes low when working on
slopes,
the engine may suck in air because of the angle of the
machine or the swaying of the machine. If this makes the engine
stop, so be careful not to let the fuel level in
the
fuel tank become
too low.
Precautions when engine stops on slopes
If the engine stops while working or traveling on a hill, immedi-
ately depress the brake pedal, lower the blade to the ground
to stop
the machine, then lock the brake pedal with the brake lock lever.
Thereafter, move the gear shift lever to the N (neutral) position,
lock the lever, then restart the engine.
