• Always file cutting teeth from the inside face. Reduce
the pressure on the return stroke. File all the teeth on
one side first, then turn the chain saw and file the teeth
on the other side. (19)
• File all the teeth to the same length. When the length
of the cutting teeth is reduced to 5/32 inch (4 mm) the
chain is worn out and should be replaced.
General advice on adjusting depth gauge setting
When you sharpen the cutting tooth the depth gauge
setting will decrease. To maintain optimal cutting
performance the depth gauge has to be filed down to
achieve the recommended depth gauge setting. See
instructions under the heading Technical data to find the
correct depth gauge setting for your particular chain. (24)
WARNING! The risk of kickback is
!
increased if the depth gauge setting is
too large!
Adjustment of depth gauge setting
• The cutting teeth should be newly sharpened before
adjusting the depth gauge setting. We recommend
that you adjust the depth gauge setting every third
time you sharpen the cutting teeth. NOTE! This
recommendation assumes that the length of the
cutting teeth is not reduced excessively.
• You will need a flat file and a depth gauge tool. We
recommend that you use our depth gauge tool to
acheive the correct depth gauge setting and bevel for
the depth gauge.
• Place the depth gauge tool over the chain. Detailed
information regarding the use of the depth gauge tool,
will be found on the package for the depth gauge tool.
Use the flat file to file off the tip of the depth gauge that
protrudes through the depth gauge tool. The depth
gauge setting is correct when you no longer feel
resistance as you draw the file along the depth gauge
tool. (25)
Tensioning the chain
WARNING! A slack chain may jump off
!
the bar and cause serious or even fatal
injury.
WARNING! Always unplug the product
!
from the power supply when assembling,
checking and/or performing
maintenance.
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.
GENERAL SAFETY PRECAUTIONS
Tension the chain as tightly as possible, but not so tight
that you cannot pull it round freely by hand. (26)
• Release the knob by folding it out until it snaps open.
• Turn the knob anti clockwise to loosen the drive
sprocket cover.
• Adjust the tension on the chain by turning the chain
tensioner wheel down (+) for tighter tension and up (-
) to loosen the tension. (A-B)
• Tighten the bar clutch by turning the knob clockwise.
• Fold the knob back in to lock the tensioning.
Lubricating cutting equipment
WARNING! Poor lubrication of cutting
!
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
Chain oil
Chain oil must demonstrate good adhesion to the chain
and also maintain its flow characteristics regardless of
whether it is warm summer or cold winter weather.
Never use waste oil! Using waste oil can be dangerous
to you and damage the machine and environment.
Filling with chain oil
• All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also
adjustable. (27)
• A full reservoir is sufficient for 15 minutes of steady
use.
• Never use waste oil. This results in damage to the oil
pump, the bar and the chain.
• It is important to use oil of the right grade (suitable
viscosity range) to suit the air temperature.
• In temperatures below 32°F (0°C) some oils become
too viscous. This can overload the oil pump and result
in damage to the oil pump components.
• Contact your service agent when choosing chain oil.
Checking chain lubrication
Aim the tip of the bar at a light coloured surface about 20
cm (8 inches) away. After 1 minute running at full throttle
you should see a distinct line of oil on the light surface.
(28)
If the chain lubrication is not working:
• Check that the oil channel in the bar is not obstructed.
Clean if necessary. (29)
• Check that the groove in the edge of the bar is clean.
Clean if necessary. (30)
• Check that the bar tip sprocket turns freely and that
the lubricating hole in the tip sprocket is not blocked.
Clean and lubricate if necessary. (31)
