and simply tiredness. That's why it's quite common for people to mistake this
very dangerous poisoning for something else.
1.3.3. To avoid Carbon monoxide poisoning DO NOT Use Petrol
/
Diesel powered equipment
inside a home or garage even if doors and windows are open.

Batteries present a risk if they become damage by the
possible leaking of electrolyte. This electrolyte is an acid and can cause serious
injuries. Care should be taken when working on or near them.

1.4.10.6.1.1.
Remove all clothing contaminated with acid.
1.4.10.6.1.2.
Get medical assistance as soon as possible.
1.4.10.6.1.3.
Use fresh running water to wash off excess acid, continue this
until medical assistance arrives.
1.4.10.6.1.4.
If acid come into contact with Eyes the acid needs to be
immediately washed away. Make sure that you do not wash the acid to
another part of the face or body.
1.4.10.6.1.5.
Gasses from charging batteries are highly flammable and great
care should be taken to charge in well ventilated areas.

CAUTION
•
If an insufficient amount of engine oil is used, damage to the
engine may result.
•
Do not overfill the engine with oil.
•
This generator is equipped with a low oil pressure switch this
system will stop the engine automatically when the oil
pressure falls below the minimum pressure required.
•
This helps prevents damage such as bearing seizures etc.
However, this should not be relied upon and the engine oil
level should be checked and topped up if required, daily.
Wear suitable PPE, suggested but not limited too
3.2. Check and refill the engine oil.
3.2.1. To ensure the generator maintains an
optimum performance and the life of the
generator is as long as possible, it is important
to use the correct engine oil - SAElOW /30 -
SAElSW/40
(
API CH-4
/
CF
/
SJ
/
SL diesel engine
oil or higher grade
)
and change after the first
20 hours
,
then ever
y
100 hours.
3.2.2. If the correct engine oil is not used, or the
engine oil is not replaced every 100 hours, as
required, the risk of crankshaft bearing failure,
piston seizure, piston ring sticking and
accelerated wear of the cylinder liner, main bearing and failure of other moving
components increases significantly. The generator lifespan will be greatly reduced if oil
level and oil changes are reduced.
Oil Dipstick
3.2.3.
Remove oil filler cap and check engine oil level
\_
Upper Level
3.2.4.
If oil level is below the lower level line, refill with SAE
API CH-4/CF/SJ/SL diesel engine oil on dipstick, or to
the top of filler neck. N.B. do not screw oil filler in the
oil filler cap when checking oil level.
3.2.5. Change contaminated oil.
3.3. Service the Air Cleaner.
WARNING
•
Do not wash air filter with detergent.
Lower level
�
•
Replace the air filter if the engine output decreases or
excessive exhaust smoke is noticed.
•
Never run the generator without the air filter, otherwise
rapid engine wear will result.

•
Explosive gases are given off when charging battery. Only charge
in a well-ventilated area, away from sparks and naked flames.
3.6.1. Battery.
3.6.1.1. When you first install the battery, ensure that the battery's polarity is the
same as the generator's battery leads - Black= negative, Red = positive.
3.6.1.2. Using a voltmeter - check the voltage is 12.3V+, if lower, the battery must be
charged.
3.6.1.3. Check that the voltage is correct every month. The battery should be
between 12.Sv and 13.6v. When the engine is running it should re-charge the
battery.
3.6.1.4. Make sure battery is free from damage and is not leaking. If battery shows
signs of damage or leaking- DO NOT continue to use. Instead replace battery
immediately.
3.6.1.5.
Make sure that all battery acid spills are correctly cleaned up straight away.
3.6.1.6.
The battery should be stored in a charged condition.
3.6.1.7. The battery is a 12 volt 36Ah sealed lead acid battery and requires no
maintenance other than;
3.6.1.7.1.
Ensure battery terminals are;
3.6.1.7.2.
Kept clean.
3.6.1.7.3.
Kept tight.
3.6.1.7.4.
Covered to prevent short circuiting.
3.6.1.8.
If the battery voltage is too low, it will require charging before use.
3.6.1.9.
Keep the battery in a cool, dry place. It is important to clean the battery every
three months and charge every six months.

4. OPERATING THE GENERATOR
&CAUT ON
•
Do not loosen or readjust either the engine speed limiting bolt or the
fuel injection limiting bolt as this will cause the performance of the
generator to be affected.
4.1. Starting.
4.1.1.
Turn the main AC switch to the 'OFF' position.
4.1.2.
Make sure that the machine has fuel for the task.
4.1.3.
Make sure the emergency STOP switch is out
(turn anti-clockwise).
4.1.4.
Set the engine speed lever is set to 'RUN'.
4.1.5.
Turn the starting key clockwise to the 'START'
position.
4.1.6. Remove your hand from the key as soon as the
engine starts.
4.1.7. If the engine does not start after 10 seconds, wait
15 seconds before trying again. Excessive start attempts will cause the battery to
flatten.
4.1.8. If it does not start after 3 attempts, or runs intermittently with excessive smoke
Page 12
4.1.8.1. Priming - before starting to prime make sure that there is fuel in tank and
that you can contain any fuel spilt.
4.1.8.1.1. It is done by releasing the pipe clip on the diesel fuel line connected to
the injector pump. Make sure you pinch the fuel line and then release slowly
until all air is released and fuel appears.
4.1.8.1.2. When fuel appears replace pipe onto the injector pump and replace
clip. Clear up any fuel spills before restarting.
4.1.8.1.3. The above may be necessary when new, or if the machine runs out of
fuel.
