Sign off on the light tower maintenance

1. Air cleaner element - Clean, Check, Replace

Proper maintenance of the air cleaner provides maximum protection against airborne dust.

Squeeze the rubber valve (Precleaner Dirt Dump) periodically to ensure that it is not clogged.

To service the air cleaners, proceed as follows:

1.2. Inspect Air Cleaner housing for any condition that might cause a leak. Correct as necessary.

1.3. Wipe inside of Air Cleaner housing with a clean, damp cloth to remove any dirt accumulation to allow a better seal for Filter element gasket.

Engine Radiator (exterior) Check

Check the coolant level in the radiator. The coolant must cover the tubes in the top tank (approximately 1 inch high on a clean measuring rod, stuck down filler neck).

WARNING: Remove pressure cap slowly to relieve pressure from HOT radiator. Protect skin and eyes. Hot water or steam and chemical additives can cause serious personal injury.

Air Intake Hoses and Flexible Hoses Check

All rubber hose joints and the screw type hose clamps must be tight and the hoses showing no signs of wear, abrasion, or deterioration.

All flexible hoses must be free of wear, deterioration, and vibration abrasion. Routing clamps must be properly mounted and secure.

Monthly spot check several capscrews and nuts for proper torque. If any are found loose, a more thorough inspection must be made and deficiencies corrected.

Engine Protection Shutdown System Check

1. Control Compartment (interior) Check

Every six months or 500 hours with the unit OFF, perform visual inspection for loose connections, dirt, arcing, or damage to electrical components.

2. Fuel Tank (fill at end of each day) Drain

In order to minimize condensation inside the fuel tank, refill as soon as possible after every use or at the end of each work day. Use only clean, low sulfur fuel. When using a funnel, ensure it is clean and free from dust. Every six months, drain any sediment or accumulated condensate from tank.

3. Fuel/Water Separator Element Replace

Every six months or 500 hours, (less if fuel is of poor quality or contaminated) replace the bowl element(s).

4. Wheel Bearings & Grease Seals Repack

Every six months the wheel bearings, grease seals, and axle spindles should be inspected for damage and wear (i.e., from corrosion, scratches, or metal particles). Replace any damaged or worn parts. Repack wheel bearings.

Use a wheel bearing grease conforming to specification N.L.G.I. #2 LIthium base grease (preferred) or MIL-G-10924 and suitable for all ambient temperatures.
