1. Important notes on safe operation of the engine HATZ diesel engines are economical, strongly built and long-lasting. They are therefore frequently chosen for commercially and industrially operated equipment and machinery. Since the engine forms part of the finished equipment or machine, its manufacturer will take all the applicable safety regulations into account. Nevertheless, we give below certain additional comments on operating safety, and would recommend you to note them carefully.
Important notes on safe operation of the engine – Stop the engine before performing any maintenance, cleaning- and repair work. – Stop the engine before refuelling. Never add fuel near a naked flame or a source of sparks. 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 a running engine.

3.2. Transport START A lug is provided on top of the engine as standard equipment, so that the engine can be lifted safely. It is not suitable for lifting complete machines or similar with the engine attached, and this is strictly prohibited. (See Chapter 2.) 3.3. STOP + Instructions for installation If you have an engine which is not yet installed in a machine and still has to be installed, make sure that the Assembly Instructions for HATZ Diesel Engines are complied with prior to installation.
3.5. Every engine is equipped with an additional loose engine type plate. If the original type plate on the engine is not readily visible after the engine is installed in the equipment then the second loose type plate must be attached on the equipment in such a manner that it is readily visible to an average person.
The engine must be in a horizontal position before adding oil or checking the oil level. 4. Operation 4.1. Before initial start-up Engines are normally delivered without fuel and oil. 4.1.1. Engine oil Qualified are all trademark oils which fulfil at least one of the following specifications: ACEA – B2 / E2 or more significant API – CD / CE / CF / CF-4 / CG-4 or more significant. 1 If engine oil of a poorer quality is used, reduce oil change intervals to 150 hours of operation.
4.1.3. Fuel Only refuel when engine is stopped. Never refuel close to open flames or flammable sparks, don’t smoke. Use only pure fuel and clean replenishing cups. Don’t spill the fuel.
At temperatures below 0 °C, winter-grade fuel should be used or parafin added to the fuel well in advance. Lowest ambient temperature when starting, in °C 0 –10 –15 –20 up to up to up to up to –10 –15 –20 –30 Paraffin content for: Summer fuel Winter fuel 20 % 30 % 50 % – – – 20 % 50 % 1 4.1.4. Mechanical oil pressure monitor (optional extra) 11 – To activate the monitor, press lever „1“ for approx. 15 seconds.

WARNING Risk of serious injury from rotating parts. Never put your hands in the guide sleeve of the cranking device while the engine is running. IMPORTANT ! Even with mechanical oil pressure monitoring the oil level must be checked every 8 – 15 operating hours (Chapter 5.2.1.). 4.2.
4.2.1. Preparations for starting – If possible, disengage the engine from any driven equipment. The auxiliary equipment should always be placed in neutral. START STOP 0 1 2 START 2292 / 6 1 18 – Turn the decompression lever until stop „1“ is reached. In this position the automatic decompression system is heard to engage and the engine can then be started; Figs. 17 and 18. STOP 2396 / 3 16 – Set speed control lever „1“ to a position between 1/2 START and max. START, according to requirements.
4.2.2. Starting with the handle – Turn the handle slowly until the pawl engages in the ratchet, then increase turning force to build up speed. The highest speed must have been reached when the decompression lever returns to the „0“ position (compression). As soon as the engine has started, pull the starting handle out of the guide sleeve. For preparations to start the engine, see Chapter 4.2.1.
– Take hold of the starting handle with both hands and turn it at increasing speed. The maximum speed of rotation must have been reached by the time the decompression lever has returned to the „0“ position (compression). As soon as the engine has started, pull the starting handle out of the guide sleeve. – If the engine backfires because the crank handle was not turned firmly enough (the engine may even start to run backwards), release the crank handle immediately and stop the engine (Chapter 4.3.).
– Always turn the start key back to position 0 before re-starting the engine. The repeat lock in the ignition lock prevents the starter motor from engaging and possibly being damaged while the engine is still running. 4.2.4. Electric starter For preparations to start, see Chapter 4.2.1. – The decompression lever remains in pos. „0“. Never operate the electric starter when the engine is running or coasting to a standstill. There is a risk of broken starter pinion or ring gear teeth.
Automatic electrical shutdown system 4.3. (additional equipment) Never stop the engine by moving the decompression lever. During breaks in work or at the conclusion of the working period, keep the starting handle and starting key in a safe place, out of reach of unauthorized persons. This is characterized by a brief flashing of all pilot lamps once the starter key has been turned to position I (Fig. 24).
– On engines with the lower engine speeds not accessible, move speed control lever „1“ back, then move stop lever „2“ in the STOP direction. Hold it there until the engine has stopped. – Once the engine is not running any longer, release the stop lever. The stop lever is returned automatically to its operating position START via a spring. Electrical system 1 2 3 4 5 27 The charge „2“ and oil pressure telltales „3“ come on. – Turn the key to the 0 position and pull it out.
5. Maintenance The engine must be stopped before any maintenance work is attempted. Comply with legal requirements when handling and disposing of old oil, filters and cleaning materials. Keep the engine’s starting key and starting handle out of reach of unauthorized persons. To immobilize engines with an electric starter, disconnect the negative battery terminal. At the end of the maintenance work, check that all tools have been removed from the engine and all safety guards, covers etc.
