Operator’s Manual for Rough Terrain Crane
immediately. For a short interval of time, you can have a hard time with the
control of the crane. You must use caution.
CAUTION
When you make many hard brake stops, the tire and the brake linings wear
prematurely.
Use more caution when the roads are wet or frozen.
Note:
If the brake system pressure low indicator illuminate, stop the crane immediately. The
crane may have a leak in the hydraulic oil system. Contact the repair facility.
(2) The crane has dual-circuit brake system. If one circuit of the system has a
malfunction, the other one can stop the crane.
WARNING
If the tire blows out suddenly during the move, do not push the brake pedal
immediately. Hold the steering wheel tightly with two hands, decrease the
speed, and move the crane to a safe area.
7.9 TRANSMISSION OPERATION
The transmission is hydraulically driven and power shifted. To step through the gears in the
transmission, follow these points:
A. The transmission has two drive modes: 2-wheel drive and 4-wheel drive. The 4-wheel
drive is a manual shift mode. Usually you use the 1
st
gear position when you start to
move the crane. The 2-wheel drive is an automatic shift mode. Usually you use the
low gear positions when you start to move the crane.
B. If it is necessary to manually shift the transmission, the gear selector must be in the
4-wheel-drive mode.
C. When you hear an unusual noise in the transmission or it is hard to move the steering
wheel, stop the crane immediately. Correct the malfunction if you can refer to the
technical documents for transmission.
D. When you park the crane, move the gear selector to the "N" position.
E. To measure the quantity of oil in the transmission, park the crane and operate the
engine at idle speed.
CAUTION
The transmission oil must be at the correct operating temperature between 180°F
and 194.4°F (82.2°C and 93.3°C).
