SAFETY
This manual contains important information on how to use the Cromtech Fire Fighting
Pump –Single Impeller model TFF150HP properly and safely. Please read through this
manual before you attempt to operate the machine.
This fire fighting pump is designed to give safe and dependable service if operated
according to the instructions.
•Always make a pre-operation inspection before starting the engine. (For more
information read the engine operational manual).
•Do not place flammable objects near the unit.
•Children and pets must keep away from the area of operation at all times.
•Never allow anyone to operate the unit without proper instructions.
•You must know how to stop the engine quickly and understand the operation of all
controls.
•Ensure the operating space is well ventilated. Avoid operating the machine in a closed
room, tunnel or other poorly ventilated places, as the exhaust fumes contain deadly
poisonous carbon monoxide. If the machine is unavoidably operated in such a place,
discharge the exhaust outside the room by a suitable means.
•Mufflers and other hot parts of the machine are dangerous. Do not touch them with
hands or any other body parts.
•Observe the following cautions when transporting. Close the fuel tank cap securely and
close the fuel tap tightly during transportation. Drain petrol from the fuel tank before
transporting over a long distance or on rough roads.
•Stop engine without fail before replenishing the fuel tank. Never replenish fuel while the
engine is running or remains hot otherwise spilled or evaporated fuel is liable to catch
fire from the engine spark or muffler heat. Wipe off spilled fuel before starting engine.
•To prevent injury, wear the following protective items: Wear ear plugs and any other
protective items required by job conditions.

OPERATING INSTRUCTIONS
Suction and discharge pipes:
To avoid air locks and make priming easy the suction pipe should be laid so that it rises
evenly from the water source to the pump. All pipe joints have to be sealed airtight and
they should be the same size or larger than the pump inlet and discharge outlet.
PRIMING
•To prime the pump, remove the priming plug and fill pump and suction pipe with water.
Pump has a non-return valve and is capable of drawing air from the normal size suction
pipes and hoses. Replace plug and start pump. If it pumps a small amount then stops,
turn it off, check the suction pipe for leaks and repeat the priming procedure until the
pump works well.
•When filled with water, self-priming pumps will gradually draw air from the suction line.
If priming a long or large diameter pipe, additional water may have to be added to the
pump at 3 minute intervals.
N.B. Do not run the pump dry of water for extended periods as it will destroy the
mechanical seal and void warranty.
HOW THE PUMP OPERATES
Before starting the pump, make sure the non-return valve is freely able to move. If the
pump fails to prime, there could be a problem with the suction pipe such as a leak, worn
impeller or too strong of a suction lift. Self-priming pumps will not self-prime with high
discharge head. If this is the case, the suction flap valve should be removed and a suction
foot valve installed on the hose.
SUCTION STRAINER
A suction hose strainer may be needed for portable pump use. This stops gravel or any large
debris getting into the pump and causing damage.
ENGINE
Engine user manual is enclosed. Using low speed extends the life of your engine. When
continually pumping, we recommend operation at approximately 3000rpm. In contrast,
high speed will increase the pump’s performance when needed as in fire fighting or intense
situations. However, be aware that pump life will eventually suffer if high speed is
continually applied.

5
TYPE OF WATER
If any liquid contains stringy or large material that may cause obstruction, a suction
strainer should be used. If the pump is needed for chemicals, you must check the pump
compatibility with your local dealer.
FIXED INSTALLATIONS
In some installations and only if the pump is used under stressful conditions, such as
pumping uphill for long distances, the pump may not work on start up.
To rectify this, a check valve should be installed between the pump and the pipe and a
gate valve should be installed on the pump discharge. If it still fails, open the valve to
release a full flow of water and close it again. It should now pump fully. Under some
conditions the procedure might have to be repeated at each start up.
STORAGE
•Make sure that the engine is completely cooled off before storage.
•Clean up oil and dust accumulation on rubber parts.
•Drain pump completely of all water.
•Cover the machine and store it in a dry place.
•For long-term storage of this petrol unit, remove fuel from the fuel tank. Also remove
fuel remaining in the fuel line and chamber of the carburettor. To drain fuel from the
chamber of the carburettor, remove the drain plug provided at the chamber and drain
the fuel.
