•
Fit the chain tensioner into the lower hole of the guide bar, then install the chain cover, and fasten the
mounting nut to finger tightness Fig 20.
•
Turn the adjuster screw 1 clockwise until the chain does not sag from the underside of the guide bar Fig 21.
•
Tighten the chain cover nut.
•
Pull the chain around the guide bar by hand to check that the chain has the correct tension, without any tight
spots.
It is important to maintain the proper chain tension. Rapid wear of the guide bar or the chain coming off can be
caused by improper tension, especially when using a new chain.
CHAIN OIL
•
Fill the chain oil tank 2 with low viscosity chain oil or 10W30 Fig 22.
•
Do not use waste or regenerated oil that can cause damage to the oil pump.
•
The oil reservoir has a capacity sufficient to provide about 20 minutes of cutting time (when set to deliver the
minimum flow rate). Be sure to refill the oil tank every time when refuelling the saw.
CHECKING THE OIL SUPPLY
•
After starting the engine, run the chain at medium
speed and see if chain oil is thrown off as shown in
the figure Fig 23.
ADJUSTING OIL FLOW RATE
Never fill the oil reservoir or adjust the oiler with the engine running
.
•
An increase in bar oil flow rate will speed oil consumption, requiring more frequent checks on the oil reservoir.
•
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 hardwood.
Adjust the pump as follows:
•
Stop the engine and make sure the stop switch is in the OFF position.
•
Place the unit on its side with the oil reservoir (1) up.
•
The oil flow adjusting screw must be pressed in slightly in order to
turn. Failure to do so could damage the pump and screw Fig 24.
•
With a screwdriver, push in on the oil flow rate adjusting screw and
turn in the desired direction (there are three incremental settings)
•
Clockwise-decrease lubrication, Counter clockwise-increase
lubrication.
