4.6 Earth connection
All Stephill products are fitted with an earth stud on the control panel this must be connected to an
earthing system or spike. Any earth spike required is dependant on the local conditions of use. The
size is determined by reference to current IEE regulations or to a competent electrician.
4.7 Fumes
Make sure that the Generator is at least 2 metres away from any building during operation. Operate
in a well ventilated unconfined area, so that fumes can be properly dispersed. Silencer outlet should
be facing an open area to prevent fumes being recirculated. There is the danger of asphyxiation due
to exhaust gases. Inhalation of poisonous exhaust fumes can lead to serious injury or death. The
generator must not be used in a poorly ventilated or enclosed area.
4.8 Noise
Ear protection may be required depending on the combined noise level of the Generator, auxiliary
load and the operator’s distance from it and the length of exposure. (Noise at Work Regulations
1989)
4.9 Battery Acid
This is corrosive and irritant by all forms of exposure. If skin contact is made wash with clean water.
4.10 Fire
Ensure that suitable fire extinguishers (AFFF or CO
2
)
are kept within close proximity of the generator.
Do not cover, enclose, or obstruct the airflow to the generator during or shortly after use, due to fire
hazard or damage to the generator from overheating. Allow the generator to cool after use before
storing away. Keep all inflammable objects clear of the Generator.
4.11 Hot parts
There is the danger of
burns as parts of the generator will become very hot during use. No part of the
engine, alternator or exhaust must be touched during or shortly after operation. Do not operate the
generator unless all guards are in place. There is a risk of burns or serious mechanical injury.
5 OPERATING INSTRUCTIONS
5.1 Pre-start checks
Before starting the generator please read the engine owners manual.
Check Fuel ‘Water & Oil level
before attempting to start. Ensure 3 way valve is in correct position. This engine is equipped with an
oil’ temperature and low water level switch and will shutdown for any of these fault conditions. Inspect
the generator visually for signs of fault or damage. Ensure battery isolator switch is switched on.
5.2 Emergency stop
The generator is equipped with an emergency stop button which should only be used in an
emergency and not for general stopping.
5.3 Three Way valve
This unit is equipped with a 3 Way valve
(3/8” BSP fittings) which needs to be set to the correct
position for the Generator to operate
‘an instruction label is located next to the fuel filler.
The Engine is fitted with a lift pump for fuel delivery but this is not capable of lifting fuel above
1524mm height with a maximum length of 3048mm and minimum internal diameter of 8mm, this
means you can only have the fuel tank 300mm below the level of the generator with 910mm of hose.
It is therefore advisable to have the remote fuel tank at a higher level than the generator fuel tank to
allow gravity feed to the lift pump. If this is not possible a remote fuel pump with a bypass valve fitted
will suffice. If in any doubt please consult manufacturer.
5.4 Fuel lift pump priming
If engine runs out of fuel do not attempt to start until fuel bowl is full of diesel this can be achieved by
pressing FUEL PUMP button until bowl is full of diesel, if this is not fitted use manual lever on fuel lift
pump. The engine should then self bleed and start.
5.5 Control panel
This generator is equipped with an RCD on the 400/230 Volt supply only.
Before connecting plugs into generator please ensure the load is turned off.
