5. Clean the outer filter (4, Figure 67) by blowing
compressed air from the inside of the filter towards the
outside. Do not use more than 205 kPa (30 psi) air
pressure.
6. Check outer filter by shinning a light through it. If small
holes or thinner parts are found on the element after
cleaning it, replace the filter.
7. Clean the inside of the air cleaner body and the inside
of the air cleaner cover. Do not use compressed air.
8. Properly install the air filter and cover.
9. After filter service be sure to install cover with arrows
pointing "UP."
NOTE: If after cleaning the outer filter, the air cleaner
clogged indicator remains "ON," replace the
outer and inner filters. Do not clean inner filter.
Water Trap
Take care of fuel spillage by using a vessel or a plastic
hose.
Drain the water trap every 250 hours.
Draining water from the fuel has to be done by hand.
A nonreturn valve in the filter head prevents the fuel from
running back to the tank. As no fuel can run back, the
pressure will remain and as a consequence no water will be
drained unless new fuel is pumped in.
Proceed as follows:
• Place the end of the hose in a vessel.
• Loosen draining nipple (2).
• Pump with hand pump (3) on the primary filter
head until all water has been forced out of water
trap (1).
• Tighten the draining nipple.
NOTE: Take care of waste oil and liquid in an
environmentally safe way!
