CHECKS AND SERVICES BEFORE STARTING ENGINE Complete all required maintenance before driving the carrier Use extreme caution when checking items beyond your normal reach. Use an approved safety ladder. Check fluid level in windshield washer reservoir on rear wall in carrier cab. Add windshield washer solvent as necessary.
Page 18
Lubricate unit as indicated on lubrication chart. Check fuel level and replenish as necessary. Refuel at the end of the work shift to minimize condensation. Engine should be turned off while refueling. Be sure area is free of open flame, sparks or any condition which could cause fuel to ignite.
ENGINE OPERATION NOTE: If engine Is being started at beginning of work shift be sure to perform all “CHECKS AND SERVICES BEFORE STARTING ENGINE” Starting Diesel Engine (Cummins) Be sure transmission is in neutral and parking Turn ignition switch fully clockwise to engage brake is applied.

Proper wiper. operating temperature is approximately 140/200øF. (60/93 øC). Check all lights and turn signals for proper operation.
BRAKE SYSTEM The air brake system includes a service brake, an emergency brake, a parking brake and a digging brake. Do not drive while low air indicator is flashing. If light comes on while carrier is moving, stop carrier in a safe area as soon as possible.

treadle valve will apply service brakes to the wheels If the air pressure gages indicate some system of the forward and rear tandem axles. There will be pressure remaining, it may be possible to drive the no braking on the wheels of the front axle. unit a short distance to remove it from a hazardous position (hold parking brake knob in depressed position and use LL1 gear range).
Page 24
Allow sufficient time for full brake system pressure (125 p.s.i.-862 kPa) to be devel- oped in upperstructure before operating unit in remote control. Move digging brake control toggle to ON position only when carrier is stopped. Maximum braking is applied to wheels when toggle is moved to ON.
STEERING SYSTEM Remote control steering Conventional steering Your unit is equipped with a steering pedal The power steering system provides low effort in the upperstructure cab.Upperstructure engine must be steering under normal conditions and greater running to provide power for remote control steering. control in the event of a blowout or soft ground.
POWER TRAIN The power train furnished on 6x4 carriers (units Transfer Case having two driving axles at rear) includes the engine, (for 6x6 units only) clutch, transmission, rear tandem axles and the necessary propeller shafts to transfer torque (power) The transfer case is a gearbox located between the between these units.
