• Do not climb on the generator - dents may cause overheating of the acoustic lining.
• Keep well clear of any moving parts on the generator at all times.
• Keep children and pets away from the generator and operating area.
• Test safety features often, emergency stop button and RCD (residual current device).
• Keep the generator canopy doors shut while running and locked if possible.
Do not remove covers and attempt to work on the generator while the engine is running.
Check the rating and electrical safety of the load before connecting the generator.
Equipment should never be connected that in total exceeds the specified rating of the generator.
Stephill generators must not be used in a flammable environment.
Operation of the machine in a saline environment will require additional corrosion protection.
The generator should always be operated on level ground and be able to bear its weight. Ensure the
generator canopy is not obstructed to allow cool air to enter the set and hot expelled air to escape.

Personal Safety
Auxiliary Power
Installation of the generator as a standby or secondary power source should only be undertaken by a fully
qualified electrician using the appropriate means of isolation from the mains supply. Installation must comply
with all applicable laws, electrical codes and wiring regulations.
A temperature range between -15⁰C and +45⁰C are the normal limits of operation. Operating outside the
range will require additional modifications.
The standard reference condition for relative humidity is 30%. Above this value the rated power must be
reduced.
The standard reference condition for total barometric pressure is 1 bar. This corresponds to an altitude of
approximately 100m. Above 100m the rated power must be reduced.
• Do not cover the generator as this can obstruct air inlet and outlets on the canopy which can cause the
generator to overheat and cause permanent damage..
The electricity produced by an engine driven generator is very similar to mains AC electricity and should be
treated accordingly.
Reference Relative Humidity

SYSTEM AS INDICATED ABOVE
Where mechanical assistance is used in lifting machines, ensure the lifting eye is used, and that all
components used to lift the machine are within their Safe Working Load (SWL).
The integral lifting beam and associated lifting eye on the generator should be regularly checked for signs of
damage or gross corrosion.
General
Safety Considerations
Lubricating Oil
Safe Lifting
New oil presents no hazard following short term exposure. Lubricants in particular used engine oil, are
potentially carcinogenic. Direct contact should always be avoided by wearing suitable rubber gloves when
handling them. Used oil should not be allowed to contact the skin. If this does occur, wash off quickly with a
proprietary hand cleanser.
Fuels and lubricants are a potential source of fire. Be careful not to spill fuel, clean up any spillages.
Inhalation or swallowing of diesel should be avoided. If in doubt seek medical advice. All other forms of
contact are an irritant and therefore should also be avoided. If skin contact is made wash with soap and
water.

SSD6000-SSD6000S-SE6000D4 12
This is corrosive and irritant by all forms of exposure. If skin contact is made wash with clean water.
For storage or long periods of inactivity, Stephill Generators recommend the following:
Before the generator is used after long term storage, all fuels and oils should be replaced.
Fire
Hot Parts
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.
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)
Ensure that suitable fire extinguishers (AFFF or CO2) 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.
Fumes
Noise
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.
Battery Acid
Long Term Storage
Generator mounts, pipes and hoses should be checked to ensure that they are un-perished following
extended periods of storage.
The generator should be stored in a clean dry area, ideally having a reasonable constant ambient
temperature, and ideally not below freezing.
Generators should be stored with oil filled to the correct capacity; Storage periods of 18 months and over
may require special lubricants and treatments. If so please seek further advice from the engine
manufacturer.

SSD6000-SSD6000S-SE6000D4 13
Before any attempt to start the generator please follow these important guidelines.
It is recommended to check the oil level BEFORE EVERY START OPERATION - Ref. Fig.9.
● Make sure the generator is on level ground.
● Remove the (either side of the engine) oil dipstick (1) from the engine and wipe with a clean cloth.
● Fully reinsert the dipstick and hand tighten.
Fig.9
Operating Instructions
Adding Engine Oil
● Remove the oil dipstick from the engine. The oil level should be between the upper (2) and lower (3) lines
on the dipstick.
Add oil If the level is low. Do not fill past the high mark on the dipstick (2). WARNING - NEVER overfill the
engine with oil. Engine damage can occur.
Refer to engine owners handbook supplied with each generator for oil specification, viscosity and typical
capacity. Alternatively navigate to the Service section at

Fault Finding
WARNING - Please be aware of the potential hazards when working on a generator. Most basic fault finding
can be completed with ease. Other aspects of fault finding may require a trained technician to undertake to
ensure the safety to yourself and others.
Reference wiring diagram(s) in this handbook - The diagrams will correct as to the time of printing. Stephill
reserve the right to change the wiring diagrams without prior warning.
Starting Sequence
Once a start request is made the DSE 3110 will then attempt to crank the engine by operating the starter
motor and fuel relay.
When the engine fires, the starter motor is disengaged. (The DSE 3110 de-energises the starter motor relay
once it detects an output frequency (Hz) from the main alternator).
If the engine fails to fire during this cranking attempt then the starter motor is disengaged for the crank rest
duration after which the next start attempt is made.
Should this sequence continue beyond 3 attempts, the start sequence will be terminated and the LCD screen
will display;
Engine Running
Viewing the Instruments
Before Fault Finding
We strongly advise before attempting any fault finding is to check the health of the generator battery. It
should measure around 12.4 to 12.6 Volts DC while the generator is at standstill.
Be aware of the service/maintenance schedule of the engine, ensuring the fuel filters are replaced regularly
along with the oil topped up and oil filter etc. - See - Service and Maintenance
Before carrying out any checks ensure all Load is unplugged from the generator and be aware of any
potential exposed Live terminals while the generator is running! All checks and tests should only be carried
out by a competent engineer.
