READ MANUAL

Personal Protective Equipment (PPE)

Carbon monoxide

Carbon monoxide is a colourless and odourless gas. Breathing it can cause death as

well as serious long-term health problems such as brain damage.

The symptoms of carbon monoxide poisoning can include the following;

Headaches, Dizziness, Nausea, Breathlessness, Collapsing or Loss of

Consciousness.

Carbon monoxide symptoms are similar to flu, food poisoning, viral infections

and simply tiredness. That is why it is quite common for people to mistake this

very dangerous poisoning for something else.

To avoid carbon monoxide poisoning DO NOT use petrol/diesel powered equipment

inside a home or garage even if doors and windows are open.

If you think you or someone around you has been affected by carbon monoxide poisoning;

eave the affected area and get fresh air immediately.

Open doors and windows and turn the machine off.

See your doctor immediately or go to hospital - let them know that you

suspect carbon monoxide poisoning.

DO NOT use in an enclosed area or a moving vehicle.

General fuel safety.

Contact the Health and Safety Executive for additional fuel safety information.

All fuels are Flammable.

Keep away from all ignition sources i.e. Heaters, Lamps, sparks from Grinding or

Welding.

Hot work on tanks that have contained fuel is extremely dangerous.

Keep work area clean and tidy. Clean up all spills promptly using correct methods i.e.

absorbent granules and a lidded bin.

Dispose of waste fuels correctly.

Petrol safety.

Always fuel and defuel in well-ventilated area.

Always wear correct, suitable and fit for purpose Personal Protective

Equipment (PPE), suggested items are as follows, but are not limited to.

Hand protection.

Protective clothing.

Respiratory protective equipment.

When defueling always use a propriety fuel retriever.

Always carry fuel in the correct and clearly marked container.

Electrical Safety.

Electricity can kill - never work on LIVE/ENERGISED equipment.

The generators are fitted with an RCD, which protects against electric shock

hazards. The RCD may not function correctly if the generator is not properly

grounded/earthed. All BE Generators have the neutral internally bonded to the

ground/earth wires.

Identify electrical isolation method and always isolate all electrical supplies,

prior to carrying out any maintenance work.

Prior to use and with all electrical supplies isolated, check all electrical cables,

plugs and connections for the following;

Are intact and have no signs of damage, to include but not limited to

bare wires, chaffing, cuts and loose wiring. If there are any signs of damage,

you should stop using the equipment. The damaged item must repaired by

an electrically competent person.

To avoid any kind of trip hazard, all trailing cables carefully routed.

Never work on or near electricity with wet hands, wet clothing, and wet gloves.

Batteries.

Batteries present a risk if they become damage by the

possible leaking of electrolyte. This electrolyte is an acid and can cause serious

injuries. Take care should when working on or near them.

Should you come into contact with acid you should;

Remove all clothing contaminated with acid.

Get medical assistance as soon as possible.

Use fresh running water to wash off excess acid, continue this

until medical assistance arrives.

If acid gets into your eyes, you should remove it immediately. Make

sure that you do not wash the acid to another part of the face or body.

Gasses from charging batteries are highly flammable. You must

charge in well-ventilated areas.

Additional Safety Instructions.

Do not enclose or cover the generator. It may become overheated if it is

enclosed. If the generator is covered, make sure to remove it and keep it well

away from the area during generator use.

Operate the generator on a level surface. It is not necessary to prepare a

special foundation for the generator. However, the generator will vibrate on an

irregular surface.

the generator is tilted/moved during operation, fuel may spill and/or the

generator may tip over, causing a hazardous situation.

used on a steep incline or slope then proper engine lubrication will not

happen. In such a case, piston seizure may occur even if the oil is above the upper

level.

Pay attention to the wiring or extension leads from the generator to the

connected device. If the wire is under the generator or in contact with vibrating

parts it may break and possibly cause a fire, generator burnout, or electric shock

hazard. Replace damaged or worn leads immediately.

DO NOT operate in rain, in wet or damp conditions, or with wet hands. The

operator may suffer severe electric shock if the generator is wet due to rain or

snow. If wet, wipe and dry it well before starting. DO NOT pour water directly

over the generator, nor wash it with water.

For each use, make sure that the generator has been electrically

grounded/earthed. Failure to do so can be fatal.

DO NOT smoke while charging a battery. The battery emits flammable

hydrogen gas, which can explode if exposed to electric arcing or open flame. Keep

the area well ventilated and keep open flames/sparks away when charging a

battery.

The engine becomes extremely hot during use and for some time after

operation. Keep combustible materials well away from generator area. Be very

careful not to touch any parts of the hot engine especially the muffler/exhaust

area or serious burns may result.

Keep children and all bystanders at a safe distance from work area

It is essential that you know the safe and proper use of the power tool or

appliance that you intend to use. All operators must read, understand and follow

the tool/appliance owners’ manual. Users must make themselves aware of the

tool and appliance applications and limitations. Follow all directions given on

labels and warnings.

Use only "LISTED" extension leads. When tools or appliances are

used/operated outside, use only extension leads marked for “Outdoor Use".

Extension leads, when not in use, should be stored in a dry and well-ventilated

area.

Always switch off generator's AC circuit breaker and disconnect tools or

appliances when not in use, before servicing, adjusting, or installing accessories

and attachments.

Stop the engine before starting any maintenance, servicing

or repair.

Only allow

properly trained personnel to maintain/repair the generator.

User manual

Under normal conditions, the air volume generated

from the radiator’s fan is enough to meet the

requirementoftheworkingroomventilation.

Theairinlettemperatureoftheengineshallbebelow

◆Reduceexhaustnoiselevel.

Overload of exhaust backpressure will cause

followingadverseeffect:

◆Outputpowerloss

◆Fuelefficiencyreduce

◆Exhaustgastemperaturerise

Note:



When more than one generator set are installed, try

not to discharge all of the generator sets’ gas from

one exhaust path. If no separated exhaust pipe is

allowed, under the condition that the total

backpressurewillnotexceedthegeneratorsets’total

backpressure a moveable separate panel shall be

installed inside of the branch exhaust pipe so that to

preventthegasfromreturn.

In the exhaust system, soft corrugated pipe shall be

used to connect the exhaust pipe with the

turbocharger, this pipe has three functions as

follows:

◆Separate the diesel engine with vibration and the

weightofexhaustpipe.

◆Compensatetheheatexpansionofexhaustpipe.

If the diesel generator set is inst

anti‐vibration base frame, the corrugated pipe can

compensatesidewaymovementwhenenginestartor

stop.

Note:

1. Serious damage will occur when rain or condensed

water enter into engine’s exhaust system.

Therefore, one water discharge opening shall be

installed in the long exhaust pipe, the position of

whichshallbeclosetothegeneratorset. 

2. When the top of the exhaust pipe is above the

2.5.4Noisereduction

Whendieselgeneratorsetis running, normally it will

bottom limit of air inlet/outlet volume needed by

engine’s normal running and the maximum allowed

value for exhaust backpressure  etc. Otherwise, the

noisereductio

expectancyofgeneratorset.

Note:



HYUNDAI Power can provide customers with overall

soundproofgeneratorset.

2.6Coolingsystem

Our standard configurationdiesel generator setsare

closed cycling water chilling units with fan and

radiator installed. Closed water chilling engine drive

the cooling pump to generate circulation power,

which keep the anti‐freeze in the paths of cylinder

body and cover continuous circulation and heat

elimination.Engine’scoolingpump,radiator(or heat

exchanger) forms a

 closed, pressure cycling and

coolingsystem.

The most common cooling system is cooling fan

directly driven by radiator and engine, which can be

replaced by heat exchanger, remote radiator or

remote cooling tower etc. If the installation position

of the remote cooling fan is relatively higher,

transmission radiator is needed to prevent the

damageofheatexchangercausedbytoobiginternal

pressure.



Note:



The dirty material stay in the radiator’s core will

greatly affect radiator’s cooling capacity. And

thereforeitisnecessarytocleantheradiatoroften.

2.6.1Coolant

Cooling system shall use the coolant which can

protecttheenginefromcontaminationandfreezing.

Coolant shall be a mixture of pure water and

anti‐freeze or pure water and anti‐rust fluid. In this

mixture, water PH value shall be between 6～8,

usually suggest to use distilled water.The specific

mixing ratio shall beaccordingto local weather, and

that of the coolant recommended by the engine



supplier,andreferencetotheoperation(preparation) 

manual of the coolant. Mix the liquids in a separate

container evenly and then add the mixture into the

radiator, ensure the anti‐freezewill notfreeze under

low temperature.

 In the area when there is low

possibilityoffreezing,thecoolantcanbeamixtureof

water and anti‐rust, according to the anti‐rust which
