Zenoah HBZ2601 Blower User Manual


 
GB-12
HB2302 / HBZ2601
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.
REPLACEMENT PLUG
HB2302 : CHAMPION RCJ6Y
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.
