EX-PS OP1
■CHECKING OIL SUPPLY
After starting the engine, run the chain at medium speed and see if chain oil is scattered off as shown in the figure. (OP1)
(1) Chain oil
NOTE
The oil reservoir has a capacity sufficient to provide about 40 minutes of cutting time (when set to deliver the minimum flow rate, or about as long as you'll get from a tank of fuel). Be sure to refill the oil tank every time when refueling the saw.
■ADJUSTING OIL FLOW RATE
WARNING
Never fill the oil reservoir nor adjust the oiler with the engine running.
IMPORTANT
An increase in bar oil flow rate will speed oil consumption, requiring more frequent checks on the oil reservoir. To ensure sufficient lubrication, It may be necessary to check the oil level more frequently than at fuel tank refills.
The guide bar and chain are lubricated automatically by a pump that operates whenever the chain rotates. The pump is set at the factory to deliver a minimum flow rate, but it can be adjusted in the field. A temporary increase in oil flow is often desirable when cutting things like hardwood or wood with a lot of pitch.
Adjust the pump as follows:
1.Stop the engine and make sure the stop switch is in the OFF position.
2.Place the unit on its side with the oil reservoir up. (OP2)
