The cartridge can also be cleaned with compressed air,
but it is important to use the following guidelines:
ALWAYS keep air pressure adjusted to less than 30
psi (2 Bar).
Wear protective glasses or a face
protector whenever air hoses are
used. Never use air pressure that Is
more than 2 Bar (30 pounds per
square inch) and make sure the air
line Is equipped with a water filter to
prevent damage to parts.
ALWAYS keep the tip of the air nozzle or air
hose at least 2 inches (50mm) from the paper
portion of the cartridge.
ALWAYS blow the cartridge clean from the
Failure to comply with the above
guidelines will damage the cartridge
and lead to severe engine damage.
Replace the cartridge If in doubt!
Do not wash or oil cartridge.
Wipe inside screen, cartridge gasket surface, inside
cover, and mounting seat before installing element.
Place cartridge on mounting seat make sure outer edge
of cartridge fits inside edge of bottom plate.
Replace cover and assemble wing bolt finger tight to
insure air filter seal.
REPLACING NEW CARTRIDGE
Replace immediately if bent, crushed, or damaged. Dry-
type air cleaners are efficient only as long as top and
bottom sealing edges are not damaged.
Also, surface of air cleaner base and cover where air
cleaner cartridge seals must be clean and not damaged,
such as dents or bends.
Often in cleaning the cartridge it is tapped against
surfaces that are not flat, thus damaging sealing edges.
Regardless of how clean the paper is, if edges are
damaged, dirt will enter the engine.
The element should be replaced every 250 hours or
when servicing does not result in full power recovery
whichever occurs first.
replacement will be required.
A 1/4 teaspoon of dust per hour can
ruin an engine In one 8 hour day.
All connections must be air tight.
Blow-by circulates into the intake manifold maintaining
crankcase pressure within a narrow range regardless of
operating speed or load.
servicing of the PCV system is confined to checking the
conditions of the hoses and connections.
CHECK OIL PRESSURE
Note oil pressure gauge which should indicate the
following pressure range at full throttle and a minimum of
0.5 Bar (7 pounds) pressure at idling speed.
2.8 - 4.1 Bar
Higher oil pressures may be experienced during cold
