Winter Pump Storage
Storing the pump in rooms where the ambient temperature is below freezing point can cause irretrievable
damage to the inner components if the pump isn’t drained properly!
Procedure to drain residual water from the pump: Switch off the engine. After pumping is completed, pump water
must be drained by unscrewing Cap 4 (see pages 2-3 Putting into Operation). Storing the pump filled with water
for a long time will cause internal corrosion of the pump blades and scale on rotating parts, therefore, reducing
the pump’s life.
Disconnect the supply hoses from the pump. Hold the starting cord handle and pull the cord
5 times
as if you are
starting the engine. By doing so, the water from the inner parts of the pump flows through Cap 4. After draining
the water, screw the cap back into the pump body.
It isn’t recommended to store the pump in rooms where the temperature drops below freezing point as a significant
change in outside temperatures can cause water vapour condensation even in areas where water is otherwise
not available. This can cause internal corrosion and significantly shorten the life of the pump and the engine.
Troubleshooting
Problem
Cause
Solution
The pump cannot create the
necessary water pressure,
interrupted water flow, low
water flow
1. Water supply is blocked
2. Low water volume
3. Non-sealing joints on the suction side of
the pump
4. Damaged pump
5. Incorrectly watered pump during self-
suction
1. Check the free flow of water
2. Use a larger diameter hose or reduce the
difference in the distance between the level
and the pump
3. Check joint tightening, replace gaskets
4. Contact a service centre
5. Check the tightness of all connections on
the suction side, water the pump as
instructed on (pages 2-3)
The engine runs well without
the load, but it’s uneven when
loaded.
1. Low engine speed
2. Blocked pump
1. Adjust the position of the speed lever
2. Remove the cause of the blocked pump
rotor
Engine
stopped
during
operation
1. The engine consumed fuel
2. The spark plug terminal dropped off
3. Low engine oil level
1. Add fuel into the tank
2. Check the spark plug terminal
3. Check the engine oil level and the
possibility to spin the engine using the
starting cord – add oil
The engine cannot be started
or it can but runs unevenly
1. Clogged air filter
2. There is no fuel in the engine
3. Old fuel
4. Spark plug terminal isn’t connected to the
spark plug
5. Inoperative spark plug
6. Fuel contaminated with water
7. Incorrect fuel/air mixture ratio
1. Clean the air filter
2. Add fuel into the tank
3. Replace fuel with new fuel or add more fuel
4. Check the spark plug terminal fitting
5. Replace the spark plug with a new one
6. Drain fuel from the tank and carburettor,
and refuel with fresh petrol
7. Contact a service centre
The engine has no power
1. Clogged air filter
2. Old fuel
1. Clean the air filter
2. Add fresh fuel into the tank
Only use original spare parts. This will ensure that your device is running smoothly.
