Daily Maintenance
WARNING!
To reduce fire hazard, keep
the engine and muffler free of dirt,
debris, and leaves.
Prior to each workday, perform the
following:
■
Remove all dirt and debris from blower
exterior and the engine. Check the
cooling fins and air cleaner for clog-
ging and clean as necessary.
Every 10 Hours
(more frequently in dusty conditions)
1. Remove the air cleaner cover by loosen-
ing 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.
IMPORTANT!
The blower uses a special high capacity
dry-type air filter element. The filter should
not be cleaned with a liquid cleaner and
must NEVER be oiled!
3. Clean the pre-filter with soap and water.
Let dry before reinstalling.
4. Inspect the air cleaner 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 com-
pressed air from the inside to blow debris
out and away from the air filter element.
WARNING!
Before performing any main-
tenance, repair or cleaning work on
the unit, make sure the engine is com-
pletely stopped. Disconnect the spark
plug wire before performing service or
maintenance work.
NOTE:
Using non-standard replacement parts
could invalidate your Shindaiwa warranty.
Muffler
This unit must never be operated with a
faulty or missing spark arrester or muf- faulty or missing spark arrester or muf- faulty or missing spark arrester or muf
fler. Make sure the muffler is well secured
and in good condition. A worn or damaged
muffler is a fire hazard and may also cause
hearing loss.
Spark Plug
Keep the spark plug and wire connections
tight and clean.
CAUTION!
The engine is cooled by air drawn
into the air intake cover on the blower
housing. The blower fan then pushes
the cooling air through an opening in
the fan housing, forcing it past the cyl-
inder cooling fins. Failure to keep the
cooling system and its passages clear
of debris will likely result in engine
overheating, a major cause of seri-
ous engine problems that can lead to
failure.

IMPORTANT!
Direct the air stream at the inside face of
the filter only!
6. Install the filter element, pre-filter and
cover in the reverse order of removal.
Fasteners
Make sure nuts, bolts, and screws (except
carburetor adjusting screws) are tight.
Air Filter
The C4 engine that powers your Shindaiwa
model is a hybrid 4-stroke engine. As a
hybrid, the engine is lubricated by oil
mixed with the gasoline and air from the
carburetor that moves through and around
the internal parts of the engine in a simi-
lar way that a 2-stroke engine is lubri-
cated. Without the heavy duty 2-stage air
filter equipped on all C4 engines, dust and
dirt could also move through the engine,
decreasing engine life, increasing valve
wear and the need for more frequent valve
adjustments. To keep your C4 engine
strong and reliable, Shindaiwa recom-
mends that you check and service the air
filter as instructed in the 10-Hour Mainte-
nance section that follows.
■
Inspect the engine, tank, and hoses
for possible fuel leaks, and repair as
necessary.
■
Inspect the entire blower for loose,
damaged, or missing components, and
repair as necessary.
■
Carefully remove any accumulations
of dirt or debris from the muffler and
fuel tank. Dirt build-up in these areas
can lead to engine overheating, fire or
premature wear.
