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.

MAINTENANCE
ENGINE MAINTENANCE
Refer to the engine manual that is included with the machine for the relevant information on engine maintenance. Your engine manual provides detailed information for performing this task.
CHANGING THE ENGINE OIL
CAUTION: PROLONGED EXPOSURE TO USED ENGINE OIL IS DANGEROUS, ALWAYS WASH YOUR HANDS THOROUGHLY AFTER HANDLING USED ENGINE OIL.
The oil in the engine must be changed after the first 20 hours use and then every 6 months or 50 running hours.
Replace the oil filter at the 3rd change of machine oil. After that, change the filter every 500 running hours.
1. Unscrew and remove the oil filler cap/dipstick.
2. Put an 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; as the oil will flow more freely.
4. Replace the drain plug.

ENVIRONMENTAL PROTECTION
One of the most damaging sources of pollution is oil, do not throw it away or pour it down drains. Put it in a leak proof container and take it to your local waste disposal site.
CHECK THE FUEL SYSTEM
Check the fuel tank monthly for contamination.
CHANGING THE FUEL FILTER
The fuel filter must be kept clean to guarantee best performance from the engine. Remove the filter from the tank and clean it every 6 months or 200 running hours. It should be replaced every year of 500 running hours.
Loosen the fuel plug and drain off the fuel.
Disconnect the high pressure fuel pump and pull out the fuel filter.
CHANGING THE AIR FILTER
CAUTION: DO NOT OPERATE THE PUMP WITHOUT THE AIR FILTER INSTALLED AS THIS WILL CAUSE EXCESSIVE WEAR TO THE ENGINE.

• If the filter is dirty, wash the foam
filter in a solution of warm water and mild detergent and rinse thoroughly. Let the filter dry fully.
• When it is dry, dip the filter in
clean engine oil and squeeze out excess oil.
• It is normal for blue smoke to come out of the exhaust for a short time
when the filter has been cleaned.
10. Replace the filter and cover.
STORAGE
Before long-term storage:
The pump must be cleaned by flushing with clean water, otherwise, the impeller may be damaged in next operation. After flushing, remove the Pump drain plug and drain all the water from the pump. Then replace the drain plug.
Run the engine briefly to consume any fuel inside.
While the engine is still warm, drain off and refill the engine oil using the draining and filling plugs previously shown
Remove the rubber plug from the cover of the rocker shaft and put about 2cc of lubricant into it before replacing the plug
