CARE AND MAINTENANCE
■ Wipe up spilled oil with a soft cloth and ret
the tank cap.
■ Make sure the guide bar and the saw chain
are in place when you check the oil delivery.
■ Switch on the product (see section
“STARTING THE CHAINSAW” ); keep
pressing the trigger switch and check if the
chain oil is delivered as shown in the gure.
(Fig. 43)
CARE AND MAINTENANCE
■ Check the drive sprocket. If it is worn or
damaged due to strain, it must be replaced
before further chainsaw use.
■ Clear residue from the rails on the guide
bar using a screwdriver, putty knife, wire
brush or other similar tool. This will keep
the oil passages open to provide proper
lubrication to the bar and chain. (Fig. 44)
■ Check the guide bar ‘rail’ for wear: Hold a
ruler (straight edge) against the side of the
guide bar and ‘cutter side plates’. If there is
a gap between the ruler and guide bar the
guide bar ‘rail’ is normal. If there is no gap
(ruler ush against the side of the guide bar)
the guide bar ‘rail’ is worn and needs to be
replaced with a new one of the same type.
(Fig. 45)
■ Reverse the guide bar from time to time
to allow for even wear, which will extend the
life span of the bar. Loosen the screw and
remove the tension disc from the guide bar.
Ensure the rubber washer on the screw is
free of wear. Turn the guide bar and x the
tension disc with the screw. Apply a drop of
suitable glue to the screw to ensure its safe
positioning when reassembled. (Fig. 45a)
CAUTION!
A chain tensioned while
warm may be too tight upon cooling.
Check the “cold tension” before next use.
CHECKING OIL LEVEL
■ Check the oil level at the window of the
oil tank (Quick View Oil Indicator) prior to
switching on and regularly during operation.
Rell oil when the oil level is lower than the
“MIN” marking. (Fig. 42)
■ Do not overll. Leave approximately 1/5
inch of space to the lower edge to allow the
oil to expand. (Fig. 41)
TENSION TEST
■ Check the chain tension by using one hand
to lift the chain above the edge of the bar.
The tension is correct when the chain lifts so
that the tie straps are approximately 3/32 -
5/32 in. (2 - 4 mm) above the bar edge.
(Figs. 29-30)
■ Adjust the tension if you nd that the
chainsaw is too loose or tight. Turn the chain
tensioning knob clockwise to tighten and
counterclockwise to loosen the chain tension.
NOTE:
A cold chain is correctly tensioned
when there is no slack on the underside of
the guide bar, the chain is snug, and it can be
turned by hand without binding.
■ Rotate the chain cover lock knob clockwise
to secure. Retension the chain whenever the
ats on the drive links hang out of the bar
groove.
NOTE:
During normal saw operation, the
temperature of the chain increases. The drive
links of a correctly tensioned warm chain will
hang approximately 1/16 in. (1.3 mm) out of
the bar groove.
NOTE:
New chains tend to stretch. Check
the chain tension frequently and tension as
required.
