ARNING: Never saw completely through the trunk.
Always leave a hinge (Fig.17-F). The hinge guides the
tree. If the trunk is completely cut through, control
over the felling direction is lost. Insert a wedge or
f
elling lever in the cut well before the tree becomes
unstable and starts to move. This will prevent the bar
from binding in the felling cut if you have misjudged
the falling direction. Make sure no bystanders have
entered the range of the falling tree before you push it
over.
WARNING: As the felling cut gets close to the hinge,
the tree should begin to fall. When tree begins to fall,
remove saw from cut, stop engine, put chain saw
down, and leave area along retreat path.
MAINTENANCE
WARNING. Use only original manufacturer’s
replacement parts, accessories and attachments.
Failure to do so can cause possible injury, poor
performance and may void your warranty.
WARNING. Servicing requires extreme care and
knowledge and should be performed only by a
qualified technician. For service we suggest you return
the product to your nearest authorized service center
for repair. When servicing, use only identical
replacement parts.
WARNING. Remove the batteries before adjustment,
maintenance or cleaning. Failure to do so could result
in serious personal injury.
You may only make adjustments or repairs described
in this manual. For other repairs, contact the
authorized service agent.
Consequences of improper maintenance may cause
the chain brake and other safety features to not
function correctly, thus increasing the potential
for serious injury. Keep your chainsaw professionally
maintained and safe.
Sharpening the chain safely is a skilled task. Therefore
the manufacturer strongly recommends that a worn or
dull chain is replaced with a new one, available from
your authorised FXA service centre.
Follow instructions for lubricating and chain tension
checking and adjustment.
After each use, clean the product with a soft dry cloth.
Check all nuts, bolts and screws at frequent intervals
for security to ensure the product is in safe working
condition. Any part that is damaged should be
properly repaired or replaced by an authorized service
centre.
REPLACING GUIDE BAR AND SAW CHAIN
CAUTION: Always be sure that the tool is switched off
and the battery cartridges are removed before
carrying out any work on the tool. Wear protective
gloves.
U
nscrew the guide bar locking knob by turning it
counterclockwise until the sprocket cover comes
loose.
Remove the sprocket cover. Remove the bar and saw
chain from unit.
Put the new chain in the correct direction onto the
guide bar and make sure that the drive links are
a
ligned in the bar groove. The cutting teeth on the
upper side of the bar must point in forward direction.
Attach the bar to the chain saw and loop the chain
around the chain driving wheel.
Replace the sprocket cover.
Adjust the chain tension.
WARNING. Improper chain sharpening increases the
potential of kick-back.
WARNING. Failure to replace or repair a damaged
chain can cause serious injury.
WARNING. The saw chain is very sharp. Always wear
protective gloves when performing maintenance to the
chain.
INSPECTING AND CLEANING THE CHAIN BRAKE
Always keep the chain brake mechanism clean by
lightly brushing the linkage free from dirt.
Always test the chain brake performance after
cleaning.
Refer to “Operation - Checking and Operating Chain
Brake” for additional information.
SHARPENING THE CHAIN SAW
WARNING. We advise you to have deep or important
sharpening carried out by a service agent who is
equipped with an electric sharpener.
When the chain penetrates into wood with difficulty, it
needs to be sharpened as follows:
1. Put the chain under tension.
2. Fasten the bar in a vice so that the chain can
slide (Fig.20)
3. File with forward strokes only until all the worn
out parts of the cutting edge is removed.
4. Count the number of strokes given to the cutter
as a reference basis and file away the same
number of strokes on all other cutters.
5. If after sharpening a few times, the depth
gauge protrudes from the template, you must
reset its level using a flat file. (Fig.21)
6. Finally round off the depth gauge. (Fig.22)
