Global Garden Products Blower BL620B Instructions Manual

							•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 fail-
ure in a job.
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.
•MUFFLER
Inspect periodically, the
muffler for loose fasteners, any damage or
corrosion. If any sign of exhaust leakage is
found, do not use the blower and have it
repaired immediately. Note that failing to do
so may result in the engine catching on fire.
Before starting operation, always make sure to
check if the muffler is properly held by three
bolts to the cylinder. (Fastening Torque: 8~12
Nm).
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.

!WARNING!
IMPORTANT
•SPARK ARRESTER
The engine is equipped with a spark arresting
screen at the exhaust port. Periodically check
and keep it in good condition.  
•AIR INTAKE SCREEN (AIR INLET NET)
Blowing air is taken in from the air inlet net.
When air flow has dropped down during opera-
tion, 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 damaged.
Never use the blower with-
out the net of the blower. Before each use,
check that the net is attached in place and is
free from any damage.
Confirm that the catching screw on the air inlet
screen is not loose. if loose, tighten it.
• HANDLING THE THROTTLE CABLE
Handle by passing the colgate tube (covering the
throttle cable and stop switch wiring) from
underneath the volute (between the anti-vibra-
tion rubber on the right and left) to the volute
cover side.
