AIR CLEANER
1. Your Compactor uses either a dry type air cleaner element or a
Dual" Oil-Foam and Paper Element. Clean the dry element or
Oil-Foam" element every 25 hours under normal conditions
and every few hours under extremely dusty conditions.
a. Clean the dry element by tapping it lightly on a flat surface.
Keep tapping until no dust comes off. The element should
be replaced if the dust does not drop off easily or if the eleĆ
ment becomes bent or crushed.
Note: Do not wash elements in any liquid of blow dirt off
with air. Do not tap element on a sharp corner, it may damĆ
age the seal.
b. Clean the Oil Foam" type element by washing it in keroĆ
sene or liquid detergent and water to remove the dirt. Wrap
the foam in a cloth and squeeze dry. Saturate the foam in
engine oil and squeeze it to remove excess oil. Assemble
the parts and reinstall air cleaner to engine.
SPARK PLUG
A dirty, oily or carboned spark plug makes starting difficult and causes
inefficient operation. Remove and clean spark plug as necessary (see
engine manual). Set spark plug gap as described in engine manual.
LUBRICATION
Clean dirt from around oil fill cap and check oil level. Oil level should
be between the FULL" and ADD" marks on the dipstick or to overflow
point in fill hole on engine without dipstick.

twenty-five (25) hours thereafter or at the end of each season. To
change oil, tilt machine back and place a pan to catch oil underneath
engine deck. Remove drain plug from engine and let oil drain into
pan.
