A new HATZ Diesel engine - working for you

This engine is intended only for the purpose determined and tested by the manufacturer of the

equipment in which it is installed. Using it in any other manner contravenes the intended purpose.

For danger and damage due to this, Motorenfabrik HATZ assumes no liability. The risk is with the

user only.

Use of this engine in the intended manner presupposes compliance with the maintenance and repair

instructions laid down for it. Noncompliance leads to engine breakdown.

Please do not fail to read this operating manual before starting the engine. This will help you to avoid

accidents, ensure that you operate the engine correctly and assist you in complying with the mainte-

nance intervals in order to ensure long-lasting, reliable performance.

Please pass this Instruction Manual on to the next user or to the following engine owner.

The worldwide HATZ Service Network is at your disposal to advise you, supply with spare parts and

undertake servicing work.

You will find the address of your nearest HATZ service station in the enclosed list.

Use only original spare parts from HATZ. Only these parts guarantee a perfect dimensional stability

and quality. The order numbers can be found in the enclosed spare parts list. Please note the spare

part kits shown in Table M00.

We reserve the right to make modifications in the course of technical progress.

This symbol identifies important safety precautions.

Please comply with these most carefully in order to avoid any risk of injury to persons or

damage to materials.

General legal requirements and safety regulations issued by the competent authorities or

industrial accident insurers must also be complied with.

1. Important safety notes when operating the engine

HATZ diesel engines are efficient, strong and durable. For this reason they are frequently installed on

equipment used for commercial purposes.

The manufacturers of such equipment must observe any relevant equipment safety regulations when

the engine forms part of an overall system.

A few general points concerning operating safety should none the less be noted.

Depending on the engine’s operating and installation conditions, equipment manufacturers and their

users may have to fit safety or protective devices in order to prevent improper use. Examples:

– Exhaust system components as well as the surface of the engine will naturally be hot and must not

be touched while the engine is running or until it has cooled down after being stopped.

– Incorrect wiring or improper operation of the electrical system may cause sparking and must there-

fore be avoided.

– Provide protection against contact with rotating parts once the engine is connected to the driven

equipment or machine.

HATZ protective guards are available for the belt drive of the cooling fan and alternator drive sys-

tems.

– Always observe the start-up information in the operating instructions before starting the engine:

this is particularly important when starting an engine with the recoil starter.

– Mechanical starting devices should not be operated by children or persons deficient in physical

strength.

– Check that all safety devices are in place before starting the engine.

– Ensure that operation, maintenance and repair of the engine are undertaken by suitably trained per-

sonnel only.

– Protect the starter key against unauthorised use.

– Do not run the engine in closed or badly ventilated rooms.

Do not breath in emissions – danger of poisoning !

– Also fuel and lubricants could contain poisonous components. Please follow the instructions of the

mineral oil producer.

Important safety notes when operating the engine

– The engine must be stopped before performing any maintenance, cleaning- or repair work.

– Stop the engine before refilling the fuel tank.

Never refuel near a naked flame or sparks which could start a fire. Don’t smoke. Don’t spill fuel.

– Keep explosive materials as well as flammable materials away from the engine because the exhaust

gets very hot during operation.

– Wear close-fitting clothing when working on the engine while it is running.

Please don’t wear necklaces, bracelets or any other things which you could get caught with.

– Please pay attention to all advice- and warning stickers placed on the engine and keep them in legi-

ble condition. Contact your next HATZ service station, if a sticker comes off or is illegible and ask

for a new one.

– We accept no liability for damage resulting from improper modifications to the engine.

Regular maintenance in accordance with the details given in these operating instructions is essential

to keep the engine in good working order.

When in doubt, consult your local HATZ service station before starting the engine.

3.2. Transport

Standard lifting lug „20“ is to allow

the engine and its auxiliaries to be

transported safely, chap. 2. It is not suitable or

approved for lifting the complete equipment to

which the engine is attached.

3.3. Notes on installation

The „Guide to selecting and installing an engine“

contains all the necessary information on engine

applications if you have an engine which has not

yet been installed in equipment and still has to

be fitted or set up. This guide is available from

your local HATZ service station.

Do not exceed the forces and torques

indicated on the speed adjustment

lever and the stop pin, otherwise you may

damage the stops and internal governor com-

ponents.

3.4. Load on engine

Operating the engine for a lengthy period off-

load or at very low loads can affect its running

quality. We therefore recommend a minimum

engine load of 15 %. If operated at such low

loads, it is best to operate the engine at a signifi-

cantly higher load for a short period before

switching it off.

– To check the oil level, remove the dipstick,

clean it - then screw it back in and finally

remove it again.

Check the oil level on the dipstick and, if

necessary, top up to the max. level.

4.1.2. Version with oilbath air cleaner

– Take off oil reservoir „1“ and fill with engine oil

as far as the mark, Figs. 8 and 9.

– Insert the filter element into the oil reservoir

with the long end „2“ leading, Fig. 8.

– Attach the oil reservoir, making sure that

sealing ring „3“ is correctly seated and

fasteners „4“ are tight.

4.1.3. Fuel

Stop the engine before refilling the

fuel tank. Never refuel near a naked

flame or sparks which could start a fire. Don’t

smoke. Use only pure fuel and clean filling

equipment. Take care not to spill fuel.

All diesel fuels which satisfy the following speci-

fications are suitable:

EN 590 or

BS 2869 A1 / A2 or

ASTM D 975 - 1D / 2D

– Remove fuel tank cap.
