Direct compressed air through the element in the
direction opposite to the normal air flow through the
element.
Move the nozzle up and down while rotating the
element. Be sure to keep the nozzle at least one inch
(25.4 mm) from the pleated paper.
NOTICE
To prevent damage to the element, never exceed a
maximum air pressure of 100 psi (700 kPa).
In the event the element is contaminated with dry dirt,
oil or greasy dirt deposits,and a new element is not
available, cleaning can be accomplished by washing,
using the air cleaner element manufacturer’s recom-
mendations.
NOTICE
It is highly recommended that new replacement
elements be installed in the unit immediately in or-
der that the unit be returned to service in the
shortest possible time. In this manner the ele-
ments just removed for cleaning can be washed
and stored as future replacement elements.
In addition, 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
vitally 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.
BATTERY
Heavy--duty, diesel cranking type batteries were in-
stalled at the factory and these should be inspected
weekly. Keep the battery posts--to--cable connections
clean, tight and lightly coated with a grease. Also the
electrolyte level in each cell should cover the top of the
plates. If necessary, top--up with clean distilled water.
TIRES
A weekly inspection is recommended. Tires that have
cuts or cracks or little tread should be repaired or re-
placed. Monthly check the wheel lug nuts for tight-
ness.
The high discharge air temperature switch will require
approximately 248
°
F (120
°
C) to actuate. The engine
coolant temperature switch will require approximately
210
°
F (99
°
C) to actuate. Replace any defective
switch before continuing to operate the unit.
A low oil pressure switch may be tested by removing it
and connecting it to a source of controlled pressure
while monitoring an ohmmeter connected to the
switch terminals. As pressure is applied slowly from
the controlled source, the switch should close at 12 psi
(.84 kgf per cm 2) and show continuity through the
contacts.
