1. Loosen the clamp ring and remove the dust cup.
Remove the baffle. Wipe the cup and baffle complete-
ly clean. Reassemble the dust cup.
2. Remove the element wing bolt and slide out the
element. Avoid knocking the element against the hous-
ing. Dirt accidentally transferred to the inside of the
outlet tube will reach the engine and cause wear.
3. Wipe the entire inside of the main body and inlet
cap screen.
A streak of dust on the clean air side of the old element
indicates a leakage problem. Be sure to remove the
cause before installing a new element.
4. Inspect the new element for possible damage.
Placing a bright light inside the element and inspecting
the outside will show up any holes or tears. Discard the
element if such damage appears.
IMPORTANT:
NEVER use an element that is
damaged. Severe engine wear and eventual fail-
ure can result if dirt gets through a hole in the ele-
ment.
5. Install the element and reassemble the end cup to
housing. Make sure the large o-ring is in place between
the end cup and the main body.
NOTE:
Keep spare elements on hand to elimi-
nate down time.
CHECK AXLE OIL LEVELS
Differential
NOTE:
The Telescopic Forklift should be on a
level surface for this procedure.
See illustration. Remove the check/fill plug (located on
opposite side of the drive shaft U-joint). If low, fill
until oil overflows the hole. Replace the plug, wait 10
to 15 minutes and repeat the fill procedure. Continue
this process until the differential is full. See the
LUBRICANTS chapter for the proper oil specification.
Replace the oil level check/fill plug.
Planetary Hubs
NOTE:
The planetary hubs can be checked with-
out jacking up the machine.
See illustration. The planetary hubs have one plug each
used for filling and draining. For checking the level
and filling, position the Wheel until the arrow points
down. Remove the fill plug. If oil does not run out, add
oil until it overflows. Check the remaining hubs the
same way. Refer to the oil specifications found in the
Lubricants chapter of this manual.
CHANGE FUEL FILTER
The frequency of filter replacement will be determined
by the cleanliness of available fuel, the care used in
storing fuel supplies and the operating conditions in
which the machine is used.
