Starting a flooded engine
Note : This paragraph refers to engines that have been flooded with fuel, NOT engines that
have suffered from water damage. If your generator has been flooded with water, it must be
returned to an authorised GMC service centre for repair.
• Some minor maintenance must be carried out, in order to start an engine that has been
flooded with fuel:
1. Disconnect the Spark Plug Cap (10), and use the included spark plug wrench to remove
the plug, by turning it anticlockwise
2. If the spark plug is fouled, encrusted or soaked with fuel, clean and adjust it as described
in 'Maintaining the spark plug'. Replace if required
3. Clean excess fuel from the combustion chamber by cranking the engine several times
GB
while the spark plug is removed. This is done by slowly pulling the Recoil Starter Cord
(16)
4. Reinstall the spark plug, and firmly tighten it with the spark plug wrench
Note: It is recommended to use a suitable torque wrench (not included), set to 20Nm, to set
the spark plug.
5. Repeat the starting procedure as if the engine was already warm, i.e. with no choke
Altitude operation
• This generator can safely and effectively be used up to the maximum altitude stated in
'Specification'
• Engine performance decreases by approximately 3.5% with every 300m of altitude
• Higher altitude operation would require alterations to the carburettor, as the air/fuel mix
would become too rich for the engine to properly operate. Contact your GMC dealer for
advice, if you require high altitude use
Choosing the voltage
Note: This generator features dual-voltage output and can be switched to supply current to
either the 110V Plug Sockets (3) or 230V Plug Sockets (6).
1. Turn the Voltage Selector Switch (4) to the required setting
2. Switch on the Circuit Breaker (7)
3. Confirm that the Voltmeter (2) reads the correct voltage
Note: This generator can supply either 100 or 230V to the relevant output sockets; it cannot
deliver both voltages at the same time.

Connecting appliances

Note: This generator is primarily designed to deliver power for electric power tools and
small- to medium-sized home appliances. It is equipped with an automatic voltage regulator
(AVR) that maintains a stable, regulated AC output, and quickly compensates for power
surges. However, delicate electronic devices with high sensitivity to changes in voltage and
frequency (e.g. computers, televisions, stereo equipment etc) should ONLY be connected
to this generator using adequate surge protection equipment. This includes caravans with
permanently installed electronic equipment, supplied by this generator.
WARNING: Before connecting a device to the generator, ALWAYS ensure that its power
rating is within the limits of the generator. When connecting multiple loads to the generator,
connect and switch on the highest powered device first, then successively the lower-powered
devices. ALWAYS ensure that the combined power of all connected devices DOES NOT
exceed the generator's power rating. Note that despite the AVR power fluctuations will occur
when connecting and disconnecting loads to the generator.
WARNING: Devices containing electrical motors require more
power upon start-up. Devices with a power rating close to
the maximum power output of the generator may not start, if
their start-up current requirements exceed the capabilities of
this generator.
Note: When using extension leads, the total length for a cross
section of 1.5mm2 should not exceed 60m; for a cross section
of 2.5mm2 it should not exceed 100m.
1. With the engine running (refer to 'Starting the engine' if the
generator is switched off), toggle the Circuit Breaker (7) to
the 'OFF' position
2. Confirm that the generator is switched to supply the correct
voltage (see 'Choosing the Voltage'), and meets the
earthing requirements (refer to 'Grounding the generator')
3. Connect the plug of the appliance to the matching socket:
• 110V devices: yellow 110V Plug Sockets (3)
• 230V devices: black 230V Plug Sockets (6)
4. Toggle the Circuit Breaker to the 'ON' position
5. Switch on the appliance(s)
Stopping the engine
1. Switch off all connected appliances, switch off the
Circuit Breaker (7), and disconnect all devices from the
receptacles
2. Toggle the Engine Switch (1) to the 'OFF' position
3. Close the Fuel Shut-Off Valve (17) by turning it into the
'OFF' position (horizontal)
Note: In an emergency, the engine can be stopped quickly and
at any time by switching off the Engine Switch (1), however,
the above procedure should always be followed, to switch the
generator off in a controlled manner.
WARNING: Immediately switch off the engine in case of
excessive engine noise or vibration, development of smoke
or smells (other than engine exhaust), defective electrical
parts, or if an appliance malfunctions, operates sluggishly or at
reduced performance.

Accessories

• Spare parts for this generator are available from your GMC dealer, or can be obtained
from toolsparesonline.com

Maintenance

WARNING: ALWAYS wear adequate personal protective equipment, including eye protection
and oil/fuel-resistant gloves, when carrying out maintenance on this generator. ALWAYS
ensure proper ventilation.
WARNING: Work away from naked flames, DO NOT smoke, and ensure petrol fumes or
spilled fuel cannot reach potential ignition sources.
WARNING: If fuel or oil is removed during maintenance, fill into suitable sealed containers
and dispose of according to laws and regulations.
WARNING: ALWAYS switch the generator off and wait until all components have completely
cooled, before cleaning or carrying out any maintenance (with the exception of oil removal;
refer to 'Changing the engine oil').
Note: The maintenance schedule should be adjusted according to use and environment.
If the generator is used frequently, and/or if it is used in harsher environments, shorter
maintenance intervals are required.
