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 let 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

CHECKING/FILLING THE ENGINE OIL BEFORE USE
WARNING: TO DO THIS CHECK, PUT THE PUMP ON LEVEL GROUND WITH THE ENGINE SWITCHED OFF.
WARNING: TAKE CARE NOT TO TOUCH ANY HOT PARTS OF THE PUMP WHEN CHECKING THE OIL LEVEL.
NOTE: The pump will normally be shipped without oil in the engine and will
require filling before use.
1. Turn the oil filler cap anti-clockwise 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.
• Fill until the oil touches the
threads in the oil fill tube.
• Oil capacity (See page 20).
• We recommend you use
SAE15W40 oil in this pump. available from your CLARKE dealer.
