GENERAL SAFETY RULES

WARNING: WHEN USING PUMPS, ALWAYS FOLLOW BASIC SAFETY
PRECAUTIONS TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK AND
PERSONAL INJURY. READ ALL INSTRUCTIONS BEFORE YOU
OPERATE THIS PUMP AND SAVE THEM FOR FUTURE REFERENCE.

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.

5. ALWAYS connect the strainer to the suction hose to stop stones and other
solids from being pulled into the pump. These can cause damage to the
pump.

6. ALWAYS keep the pump dry and clear of 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 stress on the
connections.

9. DO NOT refuel the engine while it is operating and allow the engine cool
sufficiently before refuelling.

10. DO NOT use to pump petrol (or other flammable liquids), or corrosive
chemicals. The function of this pump is to pump WATER ONLY.

11. DO NOT operate this pump in an explosive atmosphere, near combustible
materials, or where there is insufficient ventilation.

12. DO NOT let children use this pump.

13. DO NOT run the pump dry. Always fill the pump with water before starting.

14. DO NOT direct the discharge flow towards another person.

15. DO NOT over-tighten drain or filler plugs. Excessive force can damage the
threads or the pump body.

16. DO NOT direct the water discharge towards electrical wiring or equipment.

BEFORE USE

PUMP PLACEMENT

For best pump performance, place the pump near the water level, and use
hoses that are no longer than necessary. That will enable the pump to
produce the greatest output with the least self-priming time.

As head (pumping height) increases, pump output decreases. The length,
type, and size of the suction and discharge hoses can also significantly affect
pump output.

Discharge head capability is always greater than suction head capability, so it
is important for suction head to be the shorter part of total head.

CHECK THE ENGINE OIL LEVEL

WARNING: TO DO THIS CHECK, PUT THE PUMP ON LEVEL GROUND

WARNING: TAKE CARE NOT TO TOUCH ANY HOT PARTS OF THE
PUMP WHEN CHECKING THE OIL LEVEL.

1. Turn the oil filler cap anti­clockwise and remove from the oil
fill tube.

2. Clean the dipstick with a clean
cloth.

3. Put the dipstick into the oil fill tube
and then 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 ‘L’
mark on the dipstick, add oil to
the crankcase.

Change the oil in the engine after the first 20 hours use and thereafter every 6
months or 100 running hours.

1. Unscrew and remove the oil filler
cap/dipstick.

2. Put a oil collection tray below the
drain plug.

3. Unscrew the drain plug and let
the used engine oil drain from the
crankcase into the oil collection
tray.

NOTE: Drain the engine oil when the

engine is warm, this will make
sure that the oil flows out faster.
