ROTATION BEARING LUBRICATION
There is one grease zerk remote mounted in on the right side of the chassis pedestal. It is lo-
cated just above the battery compartment. This should be used to lubricate the bearing every
50 hours. Rotate the turntable at least one revolution while pumping grease into the zerk. Use
about 8 ounces (230 cc) of grease each time the bearing is lubricated.
Also, lubricate the gear teeth of the rotation bearing at the 50-hour interval. Remove the pinion
cover. Brush open gear grease, such as Mobilkote-S, on the teeth on each side of the pinion, at
four places around the bearing. Rotate the turntable several times and check the coverage of
the grease on all of the teeth. Replace the pinion cover.
BRAKE SYSTEM MAINTENANCE
W A R N I N G
The brake system of the IC-600 requires routine maintenance to ensure proper operation.
Failure to properly maintain the brake system may result in property damage, injury, or
death.
Brake Malfunction Icon:
Located on the dash display. If the icon is present during normal
crane operation, driving the crane, or operating the brakes, discontinue operating the crane and
take out of service. This icon indicates that the pressures in the brake accumulators are too low
for reliable brake operation. The problem must be found and fixed before driving the crane any
further.
To check that the brake malfunction icon is operating correctly, turn the ignition key to the ON
position, but do not start the engine. Pump the brake pedal several times to discharge the ac-
cumulators. If the icon does not turn on, there is a malfunction in the sensor or wiring. The
problem must be found and fixed before driving the crane.
CAUTION
Brake dust may be hazardous. Observe precautions to prevent breathing large amounts
of brake dust.
Brake Pads and Rotors:
Remember that the steering system on the IC-600 is non-load reac-
tive. The operator will not be able to “feel” pad or rotor problems in the steering wheel. On a
weekly basis, check to see if the rotors appear worn, grooved, warped, or otherwise damaged.
When applying the brakes, listen for squeaking. Observe the wheels for any vibration or unusu-
al motion during braking. If any of these conditions are present, a thorough inspection is re-
quired to find and fix the source of the problem.
Regardless of other indications, a thorough inspection of the pads and rotors must be per-
formed at least every 1000 hours. Remove the tire and wheel assemblies. Note that proper tire
handling equipment must be used when removing tires of this size. Inspect the pads, and re-
place them if they are cracked or worn. Replace pads if the lining without metal back plate is
less than 0.125” thick (3.2 mm). Inspect the rotors, and replace them if they are grooved or
warped. Replace rotors if they are less than 0.5” (13 mm) thick.
Brake Unloading Valve: Mounted under the floorboard of the operator’s compartment. Also
called an accumulator charging valve. The brake unloading valve sends pressure to the accu-
mulators if low pressure is detected. No routine maintenance is needed on the brake unloading
valve.
