EXPLANATION OF COMPONENTS
DECELERATION PEDAL
Do not place your foot on this pedal unnecessarily.
When passing over the top of a hill or when a load is dumped over a cliff, the load is suddenly
reduced, so there is danger that the travel speed will also increase suddenly. To prevent this, depress
the decelerator pedal to reduce the travel speed.
This pedal (6) is used to lower the engine speed. Depress this
pedal to reduce the speed when shifting between forward and
reverse or when stopping the machine.
BLADE CONTROL LEVER
POWER TILTDOZER
This lever (7) is used to lift or tilt the blade.
Lifting control
(a) RAISE:
(b) HOLD: Blade is stopped and held in this position.
(c) LOWER:
(d) FLOAT: Blade will move freely according to external force.
REMARK
When released from FLOAT position, this lever will not
return to HOLD position, so it must be moved back by
hand.
If the engine is stopped when the lever is at the FLOAT
position, the control lever will automatically return to the
HOLD position.
Before starting the engine, check that the blade control
lever is at the HOLD position. The engine will not start
when it is at the FLOAT position.
In cold weather, it will take time for the lever to be held at
the HOLD position, so hold the lever by hand at the HOLD
position for at least 1 second.
