Maintenance (continued)
Daily Maintenance
Prior to each work day, perform the
following:
■
Remove all dirt and debris from the
engine, check the cooling fins and
air cleaner for clogging, and clean
as necessary.
■
Check the entire unit for leaking fuel
or grease.
10-Hour Maintenance
(more frequently in dusty
conditions)
1. Remove the air cleaner cover by
loosening the thumbscrews and
lifting.
2. Remove and inspect the pre-filter.
If the pre-filter is torn or otherwise
damaged, replace it with a new one.
3. Clean the pre-filter with soap and
water. Let dry before reinstalling.
4. Inspect the air filter element. If the
element is damaged or distorted,
replace it with a new one.
5. Tap filter gently on a hard surface to
dislodge debris from element or use
compressed air from the inside to
blow debris out and away from the
air filter element.
10/15-Hour Maintenance
Remove and clean or replace the
spark plug.
■
Adjust the spark plug electrode gap
to 0.024 inch (0.6 mm). If the spark
plug must be replaced, use only an
NGK CMR5H or equivalent resistor
type spark plug of the correct heat
range.
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.
NOTE:
The NGK CMR5H also meets the
requirements for electro magnetic com-
pliance (EMC).
■
Carefully remove any accumula-
tions of dirt or debris from the muf-
fler and fuel tank. Check cooling
air intake area at base of crankcase.
Remove all debris. Dirt build-up
in these areas can lead to engine
overheating, fire, or premature wear.
■
Clean any debris or dirt from the
sweeper attachment.
Unscrew
fasteners
IMPORTANT!
Direct the air stream at the inside face
of the filter only!
6. Install the air filter element, pre-filter
and cover in the reverse order of
removal.
■
Check for loose or missing screws
or components. Make sure the
attachment is securely fastened.
■
Make sure nuts, bolts, and screws
(except carburetor idle speed
adjusting screws) are tight.
