Running in the engine
1. During the initial 2-3 hours of work since purchase,
run the engine at a moderate RPM.
2. We advise you in any case not to maintain your engine at
a high speed as the different components must settle with
each other during the process of ‘running in’ the engine.
3. It is at the end of the running in period that the engine will
reach its maximum power.
4. After the first two hours of work, stop and make sure that
all nuts and screws are securely fastened, and tighten
them if necessary.
Blowing
Start the blower engine, as previously described. Hold the
blower nozzle firmly about 10 - 20 cm from the ground and
move it in a sweeping motion from left to right, directing the
debris to the desired location.
• Use low throttle settings when clearing lightweight
materials from around lawns or shrubbery.
• Use medium to higher throttle settings to move
lightweight grass or leaves from driveways or paths.
• Use full throttle when moving heavy loads such as dirt
or snow.
• Be aware of your surroundings at all times and take care
when directing debris with the blower.
IMPORTANT. Blower noise increases at higher throttle
settings. Always use the lowest throttle setting required to
get the job done.
• Never operate the blower unless it is properly assembled
and in good working condition.
• Never operate the blower without a properly functioning
muffler and spark arrestor installed.
Be aware of your surroundings at all times as debris may
misdirect and cause harm to others
Use of the petrol blower
• The GMC petrol backpack blower can efficiently move
a wide variety of debris ranging from grass clippings to
gravel. As a general rule try to operate the blower at the
lowest throttle setting necessary to get the job done.
• Prior to use of the blower ensure you have read and
understood this instruction manual.
• Ensure you are wearing suitable clothing and also safety
equipment like safety glasses, ear protection and a mask
if necessary.
