MAINTENANCE
•
Lift the tip of the guide bar up to check for sag.
•
Release the tip of the guide bar and turn the chain tensioning wheel 1/2 turn clockwise. Repeat this process
until sag does not exist.
•
Hold the tip of the guide bar up and tighten the chain cover lock bolt. 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 the chain cover lock knob slightly and turn the chain tensioning wheel 1/4 turn anti
clockwise. Lift the tip of the guide bar up and retighten the chain cover lock knob. Ensure that the chain will rotate without binding.

ADJUSTING THE CHAIN TENSIO
(See Figure 33)
WARNING!
A slack chain may jump off the bar and cause serious or even fatal injury.
Always remove the battery before any assembly, maintenance and/ or checking is done on the machine.
•
The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the
slack.
•
Check the chain tension every time you refill with saw chain oil. NOTE! A new chain has a running-in period during
which you should check the tension more frequently. Tension the chain as tightly as possible, but not so tight that
you cannot pull it round freely by hand
•
Release the chain cover lock knob until it snaps open.
•
Turn the knob anti clockwise to loosen the drive sprocket cover.
•
Hold the knob and adjust the tension on the chain by turning the chain tensioner wheel down (+) for tighter
tension and up (-) to loosen the tension.
•
Tighten the chain cover by turning the knob clockwise.
•
withdraw the knob back in to lock the tensioning.
