Inching/Brake Pedal
Push on the inching/brake pedal. The service brakes
must be applied before the inching/brake pedal reaches
the floor plate. Full application of the inching/brake
pedal applies the service brakes and puts the transmis-
sion in NEUTRAL.
Lift trucks with a MONOTROL pedal: when the
inching/brake pedal is fully applied, a switch in the start-
ing circuit is closed so that the engine can be started.
Service Brakes
Check the operation of the service brakes. Push on the
brake pedal. The brake pedal must stop firmly and must
not move slowly down after the brakes are applied. The
service brakes must apply equally to both drive wheels.
The service brakes must not pull the lift truck to either
side of the direction of travel when they are applied. The
service brakes are automatically adjusted when the
brakes are applied and the lift truck changes direction.
WARNING
Loss of fluid from the brake fluid reservoir indicates
a leak. Repair the brake system before using the lift
truck. Replace the brake fluid in the system if there is
dirt, water or oil in the system.
The lift truck has a brake booster that receives
power from the hydraulic system. The brake pedal
can be difficult to push when the engine is not run-
ning because the hydraulic system is not operating.
Parking Brake
Check the operation of the parking brake. The operator
must adjust the parking brake so that the lift truck does
not move if it is parked on an incline. The parking brake,
when in good condition and correctly adjusted, will hold
a lift truck with a capacity load on a 15% grade [a slope
that increases 1.5 metres in 10 metres (1.5 ft increase in
10 ft)].
Turn the adjustment knob on the end of the lever to ad-
just the parking brake. Do not tighten the adjustment so
that the brake is applied when the lever is released. The
lever for the parking brake has a lock. Use your finger to
release the lock on the lever when the parking brake is
released.
Lift trucks with a MONOTROL pedal: when the
parking brake is applied, a switch in the starting circuit
is closed so that the engine can be started. The switch
also puts the transmission in NEUTRAL.
Steering System
WARNING
The lift truck has hydraulic power steering. The
steering can be difficult if the engine is not running.
Make sure the steering system operates smoothly and
gives good steering control.
EVERY 150 HOURS OR MONTHLY
NOTE: Do these procedures in addition to the 8 hour checks.
THRUST SCREW FOR THE
DIFFERENTIAL, H6.00–7.00XL
(H135–155XL)
(See FIGURE 19.)
Check the adjustment of the thrust screw on new lift
trucks after the first 150 hours of operation. Loosen the
lock nut and turn the thrust screw into the housing until
the screw touches the ring gear. Turn the thrust screw out
of the housing

turn and tighten the lock nut. Addi-
tional adjustment of the thrust screw is not normally
necessary after this time.
LIFT CHAINS, LUBRICATION
Lubricate the lift chains with SAE 30 engine oil. The
best procedure is to remove the chains from the lift truck
and soak them in engine oil.
WARNING
Do not repair a worn or damaged lift chain. Replace
a worn or damaged lift chain with a new chain. If a
pair of lift chains is used in the mast, both lift chains
must be replaced.
