Place the chain drive links into the bar
„
groove.
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 studs are in the
long slot of the bar. Ensure that the
chain is over the sprocket. Replace the
chain cover.
Remove all slack from the chain by
„
turning the chain adjustment 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.
Release the tip of the guide bar and
„
turn the chain adjustment screw 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 nuts by
turning them with the wrench. 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.
ADDING CHAIN & BAR LUBRICANT
Unscrew and remove the cap from the
„
oil tank.
Pour the oil into the oil tank and monitor
„
the oil level gauge. Ensure that no dirt
enters the oil tank while filling the oil in.
Put the oil cap back on and tighten it
„
up.
One full oil tank will enable you to use
„
the saw for 20- 40 min.
TRANSPORTING THE TOP HANDLE SAW
Before transporting the top handle saw, al-
ways remove the battery pack from the top
handle saw and slide the chain cover over
the bar and chain. If several cuts are to be
performed with the top handle saw, the saw
English (original instructions)
must be switch off between cuts.
GUIDE BAR COVER
See figure 1
The chain cover must be clipped onto the
chain and bar as soon as the sawing work has
been completed and whenever the machine
has to be transported.
SHARPENING THE SAW CHAIN
See figure 16 - 21
When the chain penetrates into wood with
difficulty, it needs sharpening as follows:
Put the chain under tension.
„
Fasten the bar in a vice so that the
„
chain can slide.
Fasten the file to the file holder and
„
place it on cutter at 35° angle.
File with forward strokes only until all
„
the worn out parts of the cutting edge
are taken away.
Count the number of strokes given to the
„
cutter as a reference and file away with
the same number of strokes on all other
cutters.
If the depth gauge protrudes from the
„
template after sharpening a few times,
reset its level. Use a flat file. Finally,
round off the depth gauge.
NOTE: It is recommended to have the deep
or important sharpening carried out by a
service agent who is equipped with electric
sharpener.

GUIDE BAR MAINTENANCE

When you have finished working, clean
„
out the groove and the oil passages
with a scraping hook.
Periodically trim the sides of rails using
„
a flat file. If not done in the long run,
the feather edges might break away
and damage the bar.
If one rail is higher than the other one,
„
it is necessary to make it even with a
flat file then smooth it with a file or fine
grain abrasive paper.
