43
Air Conditioning - Check
Visually check the Drier sight glass for bubbles during
operation. There should be a green coloration during
operation. If there is no green coloration present, have the air
conditioning system checked by a certified Air-Conditioning
technician. (see Service Section for detail) System contains:
2 lbs, 14 oz. of refrigerant and 3 oz of compressor oil.
Location: (1) Compressor pump is on engine - right side
engine enclosure. (2) Drier is located inside right side
engine compartment. The (3) Condenser is mounted inside
the rear door.
Air Intake Piping - Check
Visually inspect the air intake piping for wear points, damage,
loose clamps or punctures that can damage the engine. See
the Engine Manual for details.
Back-Up Alarm - Test
The back-up alarm is mounted to the top rear of the Limb
Riser. It is intended to sound whenever either or both tracks
move backward, or when the engine automatically shuts down.
• Make sure that the area behind the machine is clear of
personnel and obstacles.
• Start the engine. Make sure you are in the seat, the seat
belt is fastened, and the door closed.
• Slightly, pull the speed/direction control lever (LH
joystick) back, as if to back up the machine.
• The back-up alarm should sound immediately. The
back-up alarm should continue to sound until the
joystick is released.
• If the back-up alarm does not function, it should be
repaired immediately.
Brake System - Test
The brakes on your crawler consist of hydrostatic braking
and spring applied, hydraulically released parking brakes. If
the machine has hydrostatic power to climb a slope, it has
sufficient hydrostatic power to stop the machine.
• Climb a slope with the machine.
• Stop on the slope and observe the machine slowly creep
backward. Shallow slopes will not be enough to allow
the machine to creep.
• While observing the machine creep backward down
the slope, apply the parking brake. The brakes should
lock immediately.
• If the brakes appear to malfunction, the cause should
be repaired immediately.
Batteries - Check
ALWAYS WEAR PROTECTIVE CLOTHING AND EYE-
GLASSES WHEN WORKING WITH A BATTERY. FOR
FURTHER IMPORTANT BATTERY SAFETY INFORMA-
TION, CONSULT THE CUMMINS OWNER’S MANUAL.
Clean Terminals
1. Remove the black negative (-) cable.
2. Clean the terminal and clamp of any oxidation buildup
with a stiff wire brush. (Stroke the brush away from your
body to avoid hazardous particles.)
3. Apply a light coat of petroleum jelly around base of
terminal.
4. Reconnect the cable.
Cooling System - Drain, Flush
The cooling system is made up of a radiator that is
cooled by the engine fan and an internal surge tank.
To clean, remove the radiator cap and loosen the valve in
the bottom of the radiator. Allow to drain into an approved
container and dispose according to local laws. Radiator
drain (4) is accessible by removing the rear belly pan under
the rear of the machine (forward from the winch assembly).
