PERMISSIBLE WATER DEPTH
In water, use the machine only in the depth range where the
track frame top is above the water surface. If the cooling fan
enters water, it may be broken. In particular, take care that the
machine does not pitch forward.
(A): Allowable water depth
After working in water for long hours, supply grease to the
greasing points of the work equipment and equalizer bar.
PRECAUTIONS FOR LONG-TIME CONTINUOUS TRAVEL OPERATION
Avoid operating the machine at high speed for a long time, oth-
erwise the temperature of lubricating oil sharply rises, and that
can cause oil leakage from the track rollers or final drive and
lower durability.
If there is no way to avoid operating the machine at high speed
for a long time, stop the machine every one hour for 30 minutes
and let the track rollers and final drive cool off before starting
up the machine again.
PRECAUTIONS WHEN TRAVELING ON SLOPES
USE DECELERATOR PEDAL
When stepping on the decelerator pedal while going uphill, climbing ability will be reduced and the machine will
stop. Furthermore, the engine may stall.
USE ENGINE BRAKE
When traveling downhill, move joystick (steering, directional and gear shift lever) into low speed to run engine at
slow speed and travel down slope using the engine brake.
Do not move the joystick (steering, directional and gear shift lever) to NEUTRAL position.
When traveling down hills of more than 15 °, shift down to 1st speed (R1 or F1).
BRAKE ON DOWNHILL
When traveling downhill with the engine brake applied, use the brake as necessary to prevent overrun. Overrun
can cause a failure.
PRECAUTIONS WHEN OPERATING ON SLOPE
Pay attention to 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. This makes the engine stop, so be careful not to let the fuel
level in the fuel tank become too low.
