FUEL

Petrol is highly inflammable. Avoid smoking or bringing any n source of ignition or naked flame near fuel, this includes tools which can cause sparks such as grinders and drills. Before refueling make sure the engine has been stopped and allowed to cool down. Choose an outdoor area at least 10m from fuel storage point.

DO NOT use straight unleaded fuel.
DO NOT use 4-stroke engine oil.
YOU MUST use an unleaded fuel and Semisynthetic 2-stroke oil mixture.
For the first time ONLY a mixing ratio of 25:1 should be used to lubricate all engine parts to an optimum level. Thereafter the mix is 40:1.

How to mix the Petrol/Oil mixture.

Measure the required quantities of unleaded petrol and 2 stroke oil.
Put some of the unleaded petrol into an approved clean container. Mark the container stating that it is an unleaded petrol / 2-stroke oil mixture.
Pour in all of the 2 stroke oil. Mix the mixture until well mixed.
Pour in the remaining unleaded petrol and mix well for at least one minute. If the mixture has not been fully mixed there is a danger of the piston jamming due to insufficient oil.

Fueling The Machine

Untwist and remove the fuel cap (1), make sure that the fuel tank inlet is kept free of any debris and DO NOT allow any debris to enter the fuel tank (2).
DO NOT overfill – fill to approx. 80% of normal full capacity to allow for expansion.
Replace the fuel cap and make sure it is fully tightened. DO NOT use the machine without having the fuel cap fitted.
Fuel mixture which has not been used for over a month or more will clog the carburetor causing the engine to operate incorrectly.
DO NOT dispose of used fuel down a drain or allow it to drain into a warehouse. YOU MUST dispose of unused fuel at an authorized recycling point.

Pump placement.

For best pump performance, place the pump near the water level, anduse hoses that are no longer than necessary. This 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 significantlyaffect 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.
Minimizing suction head (placing the pump near the water level) is also very important for reducing self-priming time. Self-priming time is the time it takes the pump to bring the water along the distance of the suction head during initial operation.

Suction head installation.

Use a rigid hose, hose connector and hose clamp provided with the pump. The suction hose must be reinforced with a non-collapsible wall or braided wire construction to prevent suction hose collapse.
The suction hose should be no longer than necessary. Pump performance is best when the pump is near the water level, and the hoses are short.
Never use a suction hose with an inside diameter less than 25 mm (1 inch).
Use a hose clamp to securely fasten the hose connector to the suction hose in order to prevent air leakage and loss of suction. Verify that the hose connector sealing washer is in good condition.
Install the strainer (provided with the pump) on the other end of the suction hose, and secure it with a hose clamp. The strainer will help to prevent the pump from becoming clogged or damaged by debris.
Securely tighten the hose connector on the pump suction port.

Discharge hose installation.

Attach a hose and hose connector to the pump’s discharge port. It is best to use a short, large-diameter hose because this will reduce fluid friction and improve pump performance. LayFlat hose can be used.
A long or small-diameter hose will increase fluid friction and reduce pump output.

If the discharge hose is equipped with a shutoff valve or nozzle, do not shut off the discharge water for a long period of time, as that could cause the pump to overheat OPERATION

DO NOT operate the pump in a dry state.
Operating the pump dry will destroy the pump seal.
If the pump has been operated dry, stop the engine immediately, and allow the pump to cool before priming.

Priming the pump.

Before starting the engine, remove the filler cap from the pump chamber, and completely fill the pump chamber with water. Reinstall the filler cap, and tighten it securely.

Starting engine.

Rest the unit on a flat, firm place.
To start a cold engine, move the choke lever (2) UP to the CLOSED or START position.
Move the throttle lever (1) away from the IDLE position, but no further than the halfway point.
While holding the unit firmly, pull out the starter rope quickly until engine fires.
Move the choke lever (2) DOWN to the OPEN or RUN position, and pull out the starter rope quickly to start the engine. DO NOT let go of the recoil starter handle instead allow it to return slowly.
Allow the engine to warm up for several minutes before starting operation.
When restarting the engine immediately after stopping it, leave the choke open in the RUN position and push the primer pump several times.
Over-choking can make the engine hard to start due to excess fuel.
When the engine fails to start after several attempts, open the choke and repeat pulling the rope, or remove the spark plug and dry it.

Setting engine speed.

After starting the engine, move the throttle lever (1) clockwise to the HIGH position (2) and check pump output.
Pump output is controlled by adjusting engine speed. Moving the throttle lever in the HIGH direction (2) will increase pump output, and moving the throttle lever (anticlockwise) in the LOW direction (3) will decrease pump output.

Stopping the engine.

Except for an emergency, avoid stopping the engine while pulling the throttle lever.
After use, remove the pump drain plug, and drain the pump chamber.
Remove the filler cap, and flush the pump chamber with clean, fresh water. Allow the water to drain from the pump chamber, then reinstall the filler cap and drain plug.
Move the throttle lever (1) to the LOW position and run the engine for a half minute.
Press the STOP button until the engine fully stops.

Adjusting the idling speed.

Warm up the engine before adjusting the idling speed.
When the engine stops frequently at idling mode, turn the adjusting screw clockwise.

MAINTENANCE

Daily Inspection

Check all nuts and screws are securely tightened and no parts are missing.
Before using the machine replace any missing fixing nuts and screws.
Check for leakage of fuel.
Clear up all fuel spills immediately, repair any leaks before starting the engine

Air filter.

Check the air filter monthly.
To remove the filter, undo the hex screw with an Allen key to reveal filter element.
Clean the element in warm soapy water as necessary. Dry completely before installing.
You must clean more frequently if used under very dusty conditions.
Replace damaged filter.
DO NOT run machine without filter fitted.

Spark plug.

Check the sparkplug every 50 hours of use and clean the gap with a wire brush. The gap should be set to 0.6 – 0.7mm. When replacing with a new plug, use a Champion RCJ-6Y or NGK BPMR7A.
The spark plug MUST be fully tightened otherwise the engine willoverheat causing damage. Always complete the following steps with the engine
Undo retaining screw and lift spark plug cover clear.
Disconnect the spark plug cap carefully. Do not pull on the HT lead instead pull on the spark plug cap .
Using the supplied spark plug wrench unscrew the spark plug. in an anti-clockwise direction.
Check the spark plug visually for damage and electrode consumption, remove the carbon deposits.
Check the gap with a feeler gauge and turn the electrode on the right distance of 0.6 to 0.7mm.
To re-insert the spark plug tighten up gently by hand to avoid cross-threading, once done tighten it using a box spanner ¼ turn more.
Make sure the spark plugis tightened correctly otherwise damage can occur.
Refit the spark plug cap onto the sparkplug. off and cooled.
The use of any spark plug other than the one designated may result in the engine failing to run correctly becoming overheated and damaged.

Fuel filter.

A clogged fuel filter can cause a lack of power and poor pickup.
Remove the fuel cap (1) and empty the remaining fuel into an approved container.
With a small wire hook, pull the fuel line and filter (2) out of tank.
Disconnect the filter assembly.
If necessary, replace with new filter or clean by blowing air inside out.
