Unpacking  
Due to modern mass production techniques, it is unlikely  
that your GMC Power Tool is faulty or that a part is missing.  
If you find anything wrong, do not operate the tool until the  
parts have been replaced or the fault has been rectified.  
Failure to do so could result in serious personal injury.  
5. Do not smoke while refuelling. This is potentially  
dangerous as it may ignite the fuel and cause an  
explosion.  
6. Take care not to spill fuel. When refuelling the  
generator ensure that the motor has been switched off.  
Prevent the spilling of fuel as this may also ignite with the  
hot motor. Never refuel whilst the engine running.  
7. Be careful where you store the generator. Store the  
generator in a dry area away from inflammable liquids.  
8. Keep your distance. The generator emits exhaust  
fumes. As a safety precaution do not stand close to the  
unit whilst it is in operation. Ensure bystanders also keep  
their distance.  
9. Ensure the generator has oil. Before commencing  
the generator, ensure that the unit has been filled with  
SAE#30 4 stroke oil.

Automatic voltage regulator (AVR)  
Checking the engine oil  
This generator has been equipped with AVR technology  
which provides automatic voltage regulated power for  
continuous uninterrupted stable power supply.  
The motor of this generator is not filled with oil.  
Prior to starting the motor ensure the crank case is filled  
with SAE #30 4 stroke oil.  
The AVR maintains a regulated AC output and reacts  
substantially quicker to rapid surges in voltage, therefore,  
preventing the possibility of damage to the generator and  
attached equipment.  
Damage to the motor is not covered under warranty if the  
motor is run without oil.  
1. Before checking or refilling oil, be sure the generator is  
put on a stable and level surface, ensuring the engine  
has been switched OFF.  
Preparing the generator  
It is important to check the generator before you commence  
operating the unit.  
2. Remove the oil filler cap (5) by rotating the cap anti-  
clockwise and inspect to see the oil level.  
IMPORTANT: Ensure that the engine has oil.  
3. If the oil level is below the

outlet of the tap and with  
the wire arms compressed,  
slide the hose clamp up  
onto the connection of the  
hose and the tap.

the plastic parts; these include products containing  
benzene, trichloroethylene, chloride and ammonia.  
3. Use a vacuum to clean air inlet and outlet louvres of  
the alternator.  
7. Refill the tank with fuel and ensure there are no leaks  
between the tap and the tank, and with the fuel tap turned  
on, ensure there are no leaks where the fuel hose is fitted  
to the outlet of the tap.  
4. Take special care to keep the ventilation inlets/outlets  
free from obstruction; cleaning with a soft brush followed  
by a compressed air jet will usually be sufficient to ensure  
acceptable internal cleanliness.
