REPLACING THE GUIDE BAR AND CHAIN
7
Replace the chain drive links into the bar groove.
NOTE: Make certain of the direction of chain.
Position the chain so there is a loop at the back of the
bar.
Hold the chain in position on the bar and place the loop
around the sprocket. Raise it to an angle of approx..45
degrees. This will make it easier to place the saw chain
onto the sprocket. It is normal that the saw chain is slack.
Pre-tighten the chain tension by turning the tension plate
clockwise.
Replace the chain cover. Secure by turning the chain
cover knob clockwise. Only lightly tighten the knob as you
will still need to tension the saw chain.
TENSIONING THE SAW CHAIN
To tighten the chain, turn the tensioning wheel clockwise.
To loosen the tension, turn the tensioning wheel counter-
clockwise.
Tighten the chain cover knob by turning it clockwise.
Re-adjust tension of the saw chain when necessary.
The chain is correctly tensioned when there is no sag on the
underside of the guide bar, the chain is snug, but it can be
turned by hand without binding.
NOTE: If chain is too tight, it will not rotate. Loosen by
turning the tensioning wheel. Ensure that the chain will rotate
without binding.
NOTE: A new chain tends to stretch, check chain tension
frequently and tension as required.
REPLACING THE BAR
Disconnect chain saw from power supply.
Use a Phillips head screw driver to remove the fixing
screw. Remove the tension plate from the old bar.
Attach the tension plate to the new bar. Make sure the
round end of the clamping plate is placed in the direction
as shown below and the clamping bolt is placed at the
bottom. Tighten the fixing screw.
