Refuelling and refilling chain oil

 WARNING:

•  FOLLOW THE SAFETY PRECAUTIONS. Be careful and cautious when handling 

fuels.

•  Switch off the engine.

 CAUTION:

•  Clean the tank cap and the area around the tank after refuelling.
Refuel or refill the chain oil as follows:
1.  Thoroughly clean the area around the caps, to prevent dirt from getting into the 

fuel or oil tank.

2.  Unscrew the cap and fill the each tanks with fuel (fuel/oil mixture) and chain oil 

respectively. 

3.  Fill up to the bottom edge of the filler neck. Be careful not to spill fuel or chain oil!

4.  Tighten the tank caps by hand as far as it goes.

Lubricating the chain

 WARNING:

•  Check the chain oil tank only when the engine is switched off.
Make  sure  there  is  sufficient  chain  oil  in  the  chain  oil  tank  to  provide  good  chain 

lubrication during operation. 

Before operation or refueling, check the chain oil level and refill if necessary. 

Adjusting the chain lubrication

 WARNING:

•  Switch off the engine.
You can adjust the oil pump feed rate with adjusting screw. There are three degrees 

of the oil pump feed rate, i.e. high, middle or low.

Adjusting screw locates at the top of the chain saw. Use a screwdriver and adjust the 

amount of oil delivery appropriately.

Cleaning the oil guide 

To ensure secure operation of the oil pump, clean the oil guide groove at the housing 

and the oil feed hole in the guide bar regularly.

Checking the chain lubrication

 CAUTION:

•  Never work with the chain saw without sufficient chain lubrication. Otherwise the 

service life of the saw chain and guide bar is reduced. 

•  Before starting work check the oil level in the tank and the oil feed.

•  Pay attention to the direction of the wind and avoid unnecessary exposure to the 

oil spray.

Check the oil feed rate as follows:
1.  Start the chain saw.

2.  Hold the running chain saw approx. 15 cm (6") above a trunk or the ground (use 

an appropriate base).

3.  If the lubrication is sufficient, you can see light oil trace because oil is scattered off 

the chain. 

NOTE:

•  After turning off the chain saw, it is normal that residual chain oil drips from the oil 

feed system, the guide bar and the chain for a while. This does not mean a defect. 

Place the saw on a suitable surface.
