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.

Maintenance

WARNING.

 Before performing any maintenance on this 

blower, stop the engine and disconnect the spark plug wire.

Checking the spark plug

Check the spark plug every 10 - 15 hours of use.

Note.

 There is a replacement spark plug included with  

the blower.
1. Remove the spark plug cover.
2. Use the spark plug wrench to remove the spark plug by 

turning it counter-clockwise.

3. Clean and adjust the spark plug gap to 0.6 - 0.7mm. 

Replace any damaged or visibly worn plug with a 

CHAMPION CJ8, NGK BM6A or equivalent spark plug.

4. Install the spark plug finger 

tight in the cylinder head, then 

tighten it firmly with the spark 

plug wrench.
