If the engine comes with an electric starter,turn the starting switch to the“Off”position.

Pull the recoil handle slowly until pressure is felt by your hand

this means the piston is on the compression 

stroke

where the intake and exhaust valves are closed and then let the handle recoil back into the engine

This 

natural position will prevent rust from occurring when the engine is being stored for long periods of time

Perform 

these steps only when the engine is off

doing so otherwise will damage the engine

6. MAINTENANCE

Oil check

During operation

it is a good idea to check the oil every morning to ensure the engine has sufficient oil

Oil change

 

Engine oil is a critical factor in determining the life of your engine

Change the engine oil on time.Change the 

engine oil more frequently if the engine is used in dusty areas

Changing the oil while the engine is still warrfl will yield best results for the engine

When the oil is still warm

you 

get rapid and complete draining of the oil

Oil change procedures

•Remove the oil filler cap and drain plug to drain the oil

•Install the drain plug

and tighten it securely

•Refill with the recommended oil and check the oil level

•Install the oil filler cap

The engine oil capacity is .60 liters or .63 US quart
