To service the air cleaners on all units proceed as follows:
1. Loosen outer wing nut and remove with outer element. Inspect red window on
special inner wing nut to find small dot. If dot is not visible, remove cotter pin
and special wing nut and inner (safety) element.
2. Inspect air cleaner housing for any condition that might cause a leak and
correct as necessary.
3. Wipe inside of air cleaner housing with a clean, damp cloth to remove any dirt
accumulation, especially in the area where the element seals against the
housing.
4. Inspect the primary element by placing a bright light inside and rotating slowly.
If any holes or tears are found in the paper, discard this element. If no ruptures
are found, the element can be cleaned by one of the following procedures.
5. If a new air filter element is to be used check it closely for shipping damage. To
reset the signal indicator in the special wing nut, apply suction to the red
window.
6. Install cleaned or new elements in the reverse order to the above. Tighten wing
nuts firmly and replace cotter pin.
7. Inspect to ensure that the end cap seals tightly 360° around the air cleaner
body.
The air cleaner system (housing and piping) should be inspected every month
for any leakage paths or inlet obstructions. Make sure the air cleaner mounting
bolts and clamps are tight. Check the air cleaner housing for dents or damage
which could lead to a leak. Inspect the air transfer tubing from the air cleaner to
the compressor and the engine for holes. Make sure that all clamps and flange
joints are tight.
Gauges
The instruments or gauges are essential for safety, maximum productivity and long service life
of the machine. Inspect the gauges and test any diagnostic lamps prior to start-up. During
operation observe the gauges and any lamps for proper functioning. Refer to Operating
Controls for the normal readings.
Fuel Tank
This unit is equipped with dual tanks that can be filled from either side. Using clean fuel in the
fuel tanks is important and every precaution should be taken to ensure that only clean fuel is
either poured or pumped into the tank. When filling the fuel tank on this unit, by methods other
than a pump and hose, use a CLEAN non-metallic funnel.
Every six months the drain plugs should be removed from the tanks so that any sediment or
accumulated condensate may be drained. When replacing the drain plugs, make sure they are
tightened securely.
