Warning: · Gasoline is extremely flammable and is explosive under certain conditions.
· Refuel in a well ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where the engine id refuelled or where gasoline
is stored.
· Do not overfill the fuel when refuelling. Spilled fuel or fuel vapour may ignite. If any fuel is spilled, make sure the area is dry before starting the engine.
· Avoid repeated or prolonged contact with skin or breathing of vapour.
KEEP OUT OF REACH OF CHILDREN!
Use unleaded gasoline with a pump octane rating of 95 or higher.
This engine is designed to operate on unleaded gasoline. Unleaded gasoline produces fewer engine and spark plug deposits and extends exhaust life.
Warning: Fuel can damage paint and some types of plastic. Be careful not to spill fuel when filling your tank. Damage caused by spilling fuels not covered under
warranty.
Never use stale or contaminated gasoline or oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.
Occasionally you may hear light "spark knock" or “pinging" (metallic rapping noise) while operating under heavy loads. This in no cause for concern.
If spark knock or pinging occurs at a steady engine speed, under normal load, change brands of gasoline. If spark knock or pinging persists, see an authorized
water pump dealer.
Warning: Running the engine with persistent spark knock or pinging can cause engine damage.
Running the engine with persistent spark knock or pinging is misuse, and the Distributor's Limited Warranty does not cover parts damaged by misuse.
Checking the air cleaner filter element check
Loosen the wing nut and remove the air cleaner cover.
Check the air cleaner element to be sure it is clean and in good condition. Clean or replace the element if necessary
Warning: Never run the engine without the air cleaner. Rapid engine wear will result from contaminants, such as dust and dirt being drawn into the engine.
Water capacity check in the pump
Before operating the pump, make sure to fill the pump with enough water.
CAUTION: Do not try to run the engine without water inside, otherwise the pump will become overheated. Prolonged running of the pump without water will
damage the pump gasket. If the water in the pump is used up, stall the engine at once and fill the pump once it cools down.
Starting the engine
Picture E: (3) High (4) Low
1. Turn the fuel valve ON.
2. Close the choke lever.
Do not use the choke if the engine is warm or the ambient temperature is high.
3. Turn the engine switch to the ON position.
4. Move the throttle lever downward slightly, just past the idle position.
5. Pull the starter grip lightly resistance is felt, then pull it briskly.
Warning: Do not allow the starter grip to snap back against the engine. Return it slowly to prevent damage to the starter.
Starting up in plateau regions
In plateau or regions with high altitude, standard carburettor produces over-dense combination of fuel air, resulting in decreased engine performance and
increased fuel consumption. To keep the engine with high performance, install a carburettor main spray nozzle and readjust the adjusting screw for idle speed.
Using in plateau regions frequently with an altitude of over 1800m contact your dealer for replace the carburettor and make adjustment in advance. Even
though a proper carburettor spray nozzle is installed in the engine, the power output of the engine will drop about 3.5% with every 305mmis increase in alti-
tude. If carburettor replacement and adjustment is not done, the "plateau-effect" will be more severe than that done.
Operation
Use the water pump in regions with lower altitude than that the carburettor spray nozzle is applicable, the engine performance will decrease and become
overheated, and over- thin combination of fuel and air produce may cause severe damage of the engine.
1. Start and warm up the engine, and then open choke gradually.
2. Set the throttle valve in accordance with specified rational speed.
Stopping the engine
In case of emergency:
To stop the engine in an emergency, turn the engine switch to the OFF position.
In normal use:
1. Move the throttle lever to the SLOW position
2. Turn the engine switch to the OFF position
3. Turn the fuel valve OFF.
Maintenance
To keep the water pump at optimal performance, check and adjustment on it periodically is necessary.
Regular maintenance and service may extend its service life obviously. The Maintenance Schedule below specifies how often you should have your water pump
served, and what things need attention.
Warning: Before maintenance and service, stall the engine. If maintaining when the engine runs, make sure to perform any check in a well- ventilated area.
Exhaust emissions from the engine contains toxic carbon monoxide (CO), which may cause loss of consciousness and even life.
Caution: If the water pump is applied to pump sea water, please pump freshwater immediate! Instead after pumping sea water so as to diminish sign of corro-
sion and to make away sea water deposit.
