Checking engine oil level
For quantities of oil please refer to the engine operators manual. When checking
the engine oil level, do so before starting or more than five minutes after
stopping.
1. To check the oil level, draw out the dipstick, wipe clean, re-insert it and
draw it out again. Check to see that the oil level lies between the two
marks.

Important
When using oil of different make or viscosity from the previous one, drain old oil.
Never mix two different types of oil. Engine oil and filter should be changed after
the first 50 hours running time and then every 250 hours or every year. Oil filter
is a cartridge type mounted on the side of the engine.
Changing Engine Oil
1. Run the engine for 10 minutes to warm up the oil.
2. Your engine is provided with a sump drain pump. Turn the tap to “on”. Use
the hand pump as shown to pump out the oil into a bucket. Turn the tap to
off position and replace end cap.
