GENERAL SAFETY RULES

1. ALWAYS obey all safety precautions for the handling of fuel.

2. ALWAYS make sure that you are familiar with this pump, and follow all

instructions in this manual.

3. ALWAYS make sure that the pump is positioned correctly to prevent it from

moving during operation.

4. Keep the area adjacent to the pump clear.

6. ALWAYS keep the pump dry and clear of the discharge hose.

7. Only use parts supplied by the manufacturer. Using non-standard parts can

be dangerous.

8. ALWAYS use at least 300mm of flexible hose to make plumbing connections

to the pump. Rigid piping can put stress on the pump, causing damage. If

you use rigid piping, it must be supported to eliminate strain on the

connections.

BEFORE USE

POSITIONING THE PUMP

For optimum performance, place the pump near the water level and use

hoses that are no longer than necessary.

As “head” (pumping height) increases, pump output decreases. The length

and size of the suction and discharge hoses can also effect pump output.

The discharge head is always greater than the suction head, so it is important

for the suction head to be the smaller part of the total head.

CHECK THE ENGINE OIL LEVEL

1. Turn the oil filler cap anti-

clockwise and remove from the oil

filler tube.

2. Wipe the dipstick clean with a lint

free cloth.

3. Slide the dipstick into the oil filler

tube and remove it again. Do not

screw in the oil filler cap/dipstick

when doing this.

4. If the oil level is at or below the

‘Lower level’ mark on the dipstick,

Fill the crankcase with oil to the

‘Upper level’ mark.
