WARNING
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
•Never operate the blower without an air filter or with a
deformed or broken filter element.
•Check the air cleaner before use.
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 fil-
ter element because unfiltered dusty air will quickly
ruin the engine.
CLEANING AIR FILTER:
[HB2302]
1. Remove the air cleaner cover by pushing and pulling
back the tab on the top.
2. Use neutral detergent and warm water to clean the
filter element. After cleaning, air dry the element com-
pletely.
3. Install the filter element into the air cleaner housing
and press the cover against the housing until clicks.
If the element is broken or shrunk, replace with a new
one.
9. Maintenance
Maintenance, replacement, or repair of the emission control device and systems may be per-
formed by any non-road engine repair establishment or individual.

•Note that failing to do so may result in the engine
catching on fire.
 
IMPORTANT
•Before starting operation, always make sure to check
if the muffler is properly held by three bolts to the cyl-
inder. (Fastening Torque : 8~12 N·m)
•Even if one bolt out of three bolts is loose, the muffler
may get loose during operation which may result in
engine catching on fire.
PROCEDURES TO BE PERFORMED AFTER EV-
ERY 100 HOURS OF USE
1.Remove the muffler, insert a screwdriver into the vent,
and wipe away any carbon buildup. Wipe away any
carbon buildup on the muffler exhaust vent and cylin-
der exhaust port at the same time.
2. Tighten all screws, bolts, and fittings.
SPARK ARRESTER
•The engine is equipped with a spark arresting screen
at the exhaust port. Periodically check and keep it in
good condition. In the state of California it is required
by law (Section 4442 of the California Public Re-
sources Code) to equip a spark arrester when a gas
powered tool is used in any forest covered, brush
covered, or grass covered unimproved land.
FUEL FILTER
•A clogged fuel filter may cause poor acceleration of
the engine. Check periodically to see if the filter is
clogged with dirt. The filter can be taken out of the
fueling port using a small wire hook. Disconnect the
filter assembly from the fuel pipe and unhook the re-
tainer to disassemble it. Clean the components with
gasoline.
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 elec-
trodes 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.

HBZ2601 : NGK CMR7A
 
IMPORTANT
•Note that using any spark plugs other than those des-
ignated 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.
MUFFLER
 
WARNING
•Inspect periodically, the muffler for loose fasteners,
any damage or corrosion. If any sign of exhaust leak-
age is found, do not use the blower and have it re-
paired immediately.

AIR INTAKE SCREEN (AIR INLET NET)
 
IMPORTANT
•Blowing air is taken in from the air inlet net. When air
flow has dropped down during operation, stop the
engine and inspect the air inlet net for blocking by
obstacles.
•Note that failure to remove any such obstacles may
result in the engine becoming overheated and dam-
aged.
 
WARNING
•Never use the blower without the net of the blower.
Before each use, check that the net is attached in
place and is free from any damage.

BEFORE STORING THE BLOWER:
1. Drain a fuel tank and push the primer bulb until it be-
comes empty of fuel.
2.Remove the spark plug and drop a spoonful of 2-cycle
oil into the cylider. Crank the engine several times and
install the spark plug.
