Replace the engine oil and engine oil filter
WARNING
Be sure to set the safety bars under the body
before starting works with the body raised.
Oil is hot immediately after operation. You may
get burnt if you touch oil. Start work after oil
has cooled down.
Place the machine on a flat and rigid ground and bring it
into the posture for replacing the engine oil filter. Stop the
engine.
Discharge the engine oil
1. Put the container just under the drain plug (1) of the
engine.
2. Clean the periphery of the filler port (2) to prevent
foreign matters from entering. Remove the filler port
cap.
3. Remove the drain plug slowly so that oil will not splash
on you. Discharge oil then.
4. Check drain oil. Contact IHI’s sales service dealer if it
contains much metallic powder, foreign matters, etc.
5. Tighten the drain plug.
Replace the oil filter
1. Remove the filter cartridge (3) with the filter wrench.
2. Clean the seal surface of the filter head, and apply
engine oil thinly to the gasket surface of a new filter
cartridge (3).
3. Pour fresh engine oil into the new filter cartridge.
4. Screw the filter cartridge by hand until the gasket is
brought into contact with the seal surface of the filter
head.
5. Tighten the filter cartridge by one turn from this
condition with the filter wrench.
