Do not release lift control lever

suddenly when lowering load because

this causes severe mechanical shock.

O. TILTING OPERATIONS

The tilt control lever is mounted to the right of the lift

lever (Fig 3-1). Rate of tilt is controlled by speed of the

engine and position of the lever. Slight acceleration of

the engine and gradual movement of the tilt lever from

neutral to tilt position will produce a slow tilting action.

Accelerating the engine and pulling the lever back or

pushing it forward as far as possible increases the speed

of tilt. When the mast is tilted to desired position,

release lever smoothly to neutral position and mast will

hold at this point.

CAUTION

Figure 4-3. Fork Adjustment

Use care when tilting mast forward to

prevent the load from toppling.

Forks can be easily removed from the carriage by

releasing the locks and aligning each fork (one at a time)

the carriage to the left. Pull lever back to shift carriage

to the right.

Lift truck stability is based on principles of the counter-

balance and fulcrum (Fig 4-4). The drive axle of the lift

truck is the balancing point (fulcrum). The load is carried

at the front of the lift truck and is counterbalanced by the

counterweight on the rear of the truck.
