■ SPARK PLUG
• The spark plug may gather carbon
deposits on its firing end with
reasonable use. Remove and inspect
the spark plug every 25 hours and
clean the electrodes as necessary with
a wire brush. The spark gap should be
adjusted to .025 in (0.6~0.7mm).
• Plug manufacturers recommend
replacing the plug twice a year to avoid
unexpected plug failure in a job.
REPLACEMENT PLUG IS A NGK
CMR7H.
• Note that using any spark plugs other
than those designated may result in the
engine failing to operate properly or in
the engine becoming overheated and
damaged.
• To install the spark plug, first turn the
plug until it is finger tight, then tighten it
a quarter turn more with a socket
wrench.
IMPORTANT
Make sure that the engine has stopped
and is cool before performing any
service to the blower. Contact with
rotating blower fan or hot muffler may
result in a personal injury.
■ AIR CLEANER
• Check the air cleaner every 25 hours of
use or more frequently if used under
dusty conditions. A clogged air filter
may increase fuel consumption while
cutting down the engine power. Never
operate the blower without the air filter
or with a deformed filter element
because unfiltered dusty air may
quickly ruin the engine.
CLEANING AIR FILTER:
1. Remove the air cleaner cover.
2. Use neutral detergent and warm water
to clean the filter element. After
cleaning, air dry the element
completely.
3. Reinstall the filter.
Never forget to attach the screen. If the
screen is not attached, the cleaner will
not seal properly and the dusts come
into the cylinder.
