commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.

REPLACING BAR AND CHAIN
See Figures 13 - 17.
WARNING:
Remove the battery pack from the pruning saw and make
sure the chain has stopped before you do any work on the
saw. Failure to do so may result in accidental starting and
possible serious injury.
WARNING:
To avoid serious personal injury, read and understand all
the safety instructions in this section.
WARNING:
Never touch or adjust the chain while the motor is running.
The saw chain is very sharp; always wear protective gloves
when performing maintenance to the chain to avoid pos-
sible serious lacerations.
CAUTION:
Always wear gloves when handling the bar and chain;
these components are sharp and may contain burrs.
NOTE: When replacing the guide bar and chain, always
use the specified bar and chain listed in the Bar and Chain
Combinations section later in this manual.
MAINTENANCE
„ Remove the battery pack before you do any work on the
pruning saw.
„ Remove the bar mounting nut using the combination
wrench provided.
„ Remove the chain cover.
„ Remove the bar and chain from the mounting surface.
„ Remove the old chain from the bar.
„ Lay out the new saw chain in a loop and straighten any
kinks. The cutters should face in the direction of chain
rotation. If they face backwards, turn the loop over.
„ Place the chain drive links into the bar groove as shown.
NOTE: Make certain of 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.
„ Fit the bar flush against the mounting surface so that the
bar stud is in the long slot of the bar.
„ Replace the chain cover ensuring that the chain tension-
ing screw is aligned with its respective hole and that the
bar stud is securely in the bar stud hole in the chain cover.
„ Replace bar mounting nut.
„ Finger-tighten the bar mounting nut. The bar must be free
to move for tension adjustment.
„ Remove all slack from the chain by turning the chain
tensioning screw clockwise until the chain seats snugly
against the bar with the drive links in the bar groove.
„ Lift the tip of the guide bar up to check for sag.
„ Hold the tip of the guide bar up and tighten the bar mount-
ing nut securely.
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 bar
nut slightly and turn the tension adjuster 1/4 turn counter-
clockwise. Lift the tip of the guide bar up and retighten the bar
nut securely. Ensure that the chain will rotate without binding.
ADJUSTING CHAIN TENSION

WARNING:
Shut off the motor, wait for all moving parts to stop, and
remove the battery pack. Never touch or adjust the chain
while the engine is running. The saw chain is very sharp.
