The danger of suffocation!

Parts

Preparing the commissioning

Mounting the feet

Screw the four feet (11) to the frame using the four locking nuts (12).

Connecting the water admission hose

Use a customary hose, hose connection, and clamp. The water admission hose must be through and not be kinked. The length of the hose should not exceed the length absolutely required.
The lower the distance to the water surface is, the bigger is the suction effect.
The suction time varies as a function of the length of the water admission hose. The filter corresponding to the water pump should be connected at the end of the water admission hose with the help of a hose clamp.

Preparing the conveying hose

Connection 80 mm (3″)

The conveying hose is not included in the delivery.

Slide a hose clamp ( 29 ) and screwing piece ( 30) onto the conveying hose (A).
Put the hose nozzle ( 31) into the conveying hose and fix using the hose clamp ( 29 ).
Put the O-ring ( 32 ) into the screwing piece ( 30 ).
Screw the conveying hose to the outlet (1) of the pump.

Preparing the suction hose

Connection 80 mm (3″)

The suction hose is not included in the delivery.

Slide a hose clamp (29 ) and screwing piece ( 30 ) onto the conveying hose (B).
Put the hose nozzle ( 31 ) into the suction hose and fix using the hose clamp (29).
Put the O-ring ( 32 ) into the screwing piece ( 30 ).
Screw the suction hose to the inlet (3) of the pump.
Slide a hose clamp ( 29 ) onto the other end of the suction hose (B).
Put the suction basket ( 33 ) into the suction hose and fix using a hose clamp ( 29 ).

Attention!

Attach the filter firmly to the water admission hose before pumping. The filter will rinse out contaminations that block the passage and could damage the impellers.
Make sure that the hose connection and clamp are safely installed to avoid any intake of air and a consequential fall of the pump power. A loose water admission hose will reduce the power of the water pump and the self-aspiration feature.

Connecting the water outlet hose

Use a customary hose, hose connection, and clamp. A short hose with large diameter is best. A long hose with small diameter will increase the flow resistance and reduce the power of the water pump.

Note! Tighten the clamp to avoid it falling off with the pressure increasing.

Controlling the motor oil level

Attention!

The quality of the motor oil is one of the decisive parameters defining the power and service life of the motor. Neither use dirty motor oil nor vegetable oil.
Control the motor oil level with the motor being switched off and the pump standing on a firm, level surface.
Only use motor oil SAE 15 W/40 mineral for winter/summer.

Motor oil pressure switch

The motor oil pressure switch is meant to avoid a damage of the motor due to too low an oil level. Before the motor oil level inside the crankcase falls beneath the safety mark, the motor is switched off automatically (even with the main switch being set to “ON”). Whenever the motor stops and cannot be started again, first check the oil level.
For this purpose, screw out the oil gauge and wipe it clean; then re-stick it into the oil orifice without screwing it in, then take it out again to read the oil level. In case the oil level is too low, top up with the correct type of oil until the oil level reaches the upper end of the oil orifice.

Attention! Operating the device with too low a motor oil level can cause serious damage to the motor!

Controlling the fuel level

Remove the tank lid and check the fuel level; if it is too low, top up.
Only use the petrol indicated in the manual (we recommend using non-leaded petrol).
Do not use any mixture of motor oil and petrol or dirty petrol. Avoid that dirt, dust, or water get into the fuel tank.

Attention!

Petrol is highly flammable and can explode under certain conditions.
Only top up with petrol with the motor being switched off and in a well-ventilated place. In the place of topping up, smoking and naked flames, sparks, etc. must absolutely be avoided.
Close the tank lid firmly again after topping up.
When refueling the device, avoid spilling petrol; petrol and petrol fumes are highly flammable. Wipe up spilt petrol with a cloth before operation.
Do not leave the pump operating in a closed room; the exhaust pipes of the motor contain toxic carbon monoxide (CO) that provoke unconsciousness or even death.
Avoid repeated inhalation of petrol fumes and any contact of petrol with your skin.
Store petrol out of children’s reach.

Controlling the air filter element

Remove the winged nut, washer, and cover. Check the filter insert; if it is dirty or clogged, clean it.

Attention! Do not let the motor run without an installed air filter; otherwise, dirt and other contaminations can penetrate the motor through the carburetor, provoking an early wear of the motor.

Controlling the water level inside the pump

Before the pump is used, it must be filled with a sufficient quantity of water.

Attention! Never operate the pump without water filled it; otherwise, it will overheat, and the gaskets of the pump will be destroyed. In case the pump is empty and has run hot, stop the motor, wait until it has cooled down, then fill in new water.

Operation

Before the operation

For your own safety and for a maximum of service life of your device, it is vital to take a few minutes to check the condition of the device; after that, you can operate it. Do not ignore any problem found; repair it or have a specialist repair it.
Make sure that the pump stands on an even surface and that the switch of the motor is set to the “OFF” position.
To avoid fire hazards, keep the pump away from walls and other devices a minimum distance of 1 m. Do not place flammable objects near the motor.
The exhaust fumes contain toxic carbon monoxide. Avoid inhaling the exhaust fumes. Never let the engine run inside a closed garage or another closed area!

Attention!

In case you do not maintain the pump correctly or do not repair any problem before further use, this might lead to dysfunctions and to serious injuries.
Before every operation, visually examine the pump and repair any problem found.

Controlling the condition of the pump

Inspect the pump to find damages.
Search for signs of oil or petrol leakage under the pump and around it.
Remove excesses of dirt and deposits, particularly around the exhaust pipe and hand starter.

Controlling the suction hose and pressure hose

Check the general state of all hoses. Make sure that the hoses are ready for use before connecting them to the pump. Keep in mind that the suction hose needs to have a (spiral) reinforcement.
Check the condition of the seal washer inside the suction hose connection point.
Check if the hose connections and clamps are correctly attached.
Check if the filter is in good condition and correctly installed on the suction hose.

Controlling the motor

Check the oil level. To avoid any sudden switching off caused by the motor oil alert system, always check the motor oil level before operation.
Check the air filter. A dirty air filter hinders the air supply to the carburetor and reduces the power of the motor and pump.
Check the petrol level. Starting with the tank filled up helps to avoid or reduce interruptions of the operation due to the need of refueling.

Starting the motor

Prepare the pump and fill in water.
Switch the fuel cock to the “ON” position.
For starting a cold motor, set the throttle to the “CLOSED” position. For starting a warm motor, the throttle should be set to the “OPEN” position.
