INSTRUMENTS AND CONTROLS
The IC-20-1J has a lower and upper instrument panel. The lower panel consists of the
standard engine instruments and controls. These instruments show the electrical
system voltage, water temperature, oil pressure, and fuel level. There are also controls
for the gas/LPG functions and throttle. Also on this panel are the headlight switch, horn
button and a “check engine” light. A bubble level is mounted to the left of the panel for
leveling the crane. (When unit is equipped with optional diesel engine, this panel will
also include glow plug light and glow plug button.)
At the top of the upper instrument panel is located the hydraulic-oil temperature gauge,
the anti-two-block override key switch and below them is the hour meter. The ignition
switch is mounted on the vertical portion of this panel. The ignition switch is key
operated and has “Start”, “Run” and “Off” positions. The ignition switch should always
be turned off and the key removed when the vehicle is left unattended.
A pedal activated service brake is provided to assist slowing down on slopes. The foot
pedal activates hydraulic disc brakes mounted on each torque hub. The parking brake
is applied by actuating a toggle switch located on the lower right side of the transmission
control lever panel, and above it is the parking brake indicator light.
The hydrostatic transmission control lever is located to the right of the steering wheel.
After the engine is started and the throttle is set, release the parking brake and move the
control lever smoothly until the desired speed is reached. Always operate this
transmission control lever smoothly. If lever is released while moving, the crane will stop
suddenly and may cause loss of control of load.
For maneuvering in tight quarters the throttle should be set for low speed. For traveling
longer distances the throttle may be set to full speed. The vehicle speed is controlled by
the transmission lever.
The hydrostatic transmission will normally stop the crane on a grade, but some oil will
slip through the wheel drive motors and allow the crane to creep. ALWAYS apply
parking brake when operating the crane, or leaving the crane unattended. Remember
the hydrostatic transmission is NOT a parking brake.
Be sure to release parking brake before moving the transmission control lever toward
forward or reverse.
The crane will “coast” on some downhill ramps when the surface is uneven and one
wheel is raised off the ramp. The forward motion of the crane may not always be
satisfactorily controlled by the hydrostatic wheel drive motors under these conditions.
The foot brake can be applied if the operator feels the machine is traveling faster than
desired.
On other surfaces the crane may slow down or stop because one drive wheel is
spinning. The engine speed and/or transmission speed may be increased gradually to
resume motion.
