Maintenance (continued)
10-Hour maintenance
(more frequently in dusty conditions)
1. Remove the air cleaner cover by
loosening the cover screw(s) and
lifting.
2. Remove the air cleaner element.
■
In dusty applications the filter
should be gently blown out with
compressed air daily or 2 to 3 times
per week.
IMPORTANT!
Direct the air stream at the inside face
of the filter only!
■
Once each week the filter should
be cleaned with a petroleum sol-
vent such as mineral spirits to
loosen and flush out debris trapped
between the filter halves. Allow the
filter to dry thoroughly before using
again. When the felt becomes
unraveled the filter should be
replaced.
10/15-Hour maintenance
Remove and clean or replace the
spark plug.
■
Adjust the spark plug electrode gap to
0.6 mm (0.024 inch). If the spark plug
must be replaced, use only an NGK
BPM8RY spark plug.
CAUTION!
Before removing the spark plug,
clean the area around the plug to
prevent dirt and debris from getting
into the engine's internal parts.
Gearcase lubrication
■
Lubricate the cutter assembly
gearcase by pumping one or two
strokes of lithium-base grease into
the grease fitting (A) using a lever-
type grease gun.
CAUTION!
Over lubricating can cause the gear-
case to operate sluggishly and can
cause grease to leak out.
