1. The shape of the cutters is divided in:
a. full chisel (square cutter for professional chain saws) fig. 37a.
b. semi-chisel (chamfered cutting edge for semi-professional and
consumer saws) fig. 37b.
2. The chain pitch determines the size of the chain. Pitch is equal
to the distance between 3 consecutive rivets, divided by 2 and is
expressed in inches according to international standards.
(fig. 37B).

inches = (mm) mm = (inches)

3. The gauge of the drive link is the thickness of the drive link
part which extends into the guide bar groove. (fig. 37C).
CAUTION! Use only approved and original
replacement saw chains and guide bars. Data for the
correct saw chain of your chain saw is listed in the
section "Technical Specifications".
CHAIN TENSION
Correct chain tension is most important for the life of chain, bar
and sprocket.
Regularly check the chain tension after the engine has been
stopped and bar and chain have cooled down. Prior to re-
tensioning, loosen nuts for the side cover. (Also refer to section
'Assembly", item 4).
Follow all instructions carefully on saw chain sharpening.
Incorrectly sharpened chain causes additional load and premature
wear to the chain as well as guide bar. Increased risk of kick-back
results from excessively large depth gauge settings.
Saw Chain Sharpening (fig. 38/29/40)
Caution! Prior to any maintenance on the saw chain,
always switch off engine and wear protective gloves!
- For sharpening, use the correct diameter, special saw chain
file (refer to filing chart). Standard round files are not suitable.
– File on the forward stroke only (see arrow), not on the back
stroke. (fig. 38)
- File the shortest cutter first. The length of that cutter will be
the guide length for all other cutters (fig. 38). All cutters should
end up the same length.
- A filing guide makes filing much easier. A guide shows the
correct filing angle (align markings parallel to the saw chain)
and limits the filing depth to 4/5 of the file diameter. (fig. 39).
General Filing Instructions
1. Support file holder on cutter top plate.
2. File all cutters on one side from inside out, then sharpen the
other side.
3. Align markings on the file holder parallel to the saw chain.
4. File as much as to remove any damage to the cutting edge on
top and side plate of the cutter.
For your safety: When advancing chain by hand
during the filing process, always move the chain
towards the guide bar tip. This avoids injury should your hand slip (fig.7).

Setting Depth Gauge (fig. 40)
The gap between the depth limiter (round nose) and the cutting
edge of the cutter determines the thickness of the chip. The best
cutting performance is achieved with the recommended depth
gauge gap.
1. Check the depth gauge setting with every sharpening
2. Place depth gauge tool (not included with saw) on top of cutter.
If the depth gauge projects above the tool level, file off with flat
file.
3. Round off the front corner of the depth gauge to its original
shape.
Caution! An excessively large depth gauge
gap causes chain vibration and increases
the risk of kick-back!
Guide Bar Maintenance (fig. 41)
The guide bar of your saw chain requires maintenance just like
the saw chain. The bar rails must be square and flat and the bar
groove must not be widened. To prevent uneven wear of the
guide bar we recommend you turn the bar over after each
sharpening of the chain. On sprocket nose guide bars, grease
the sprocket with bearing grease. Use a special grease gun and
force the grease through a small lubrication hole on the side of
the sprocket nose. Grease after every refueling and rotate the
sprocket for good coverage. (fig. 43). (Also see "Maintenance
Chart")
Important! Guide Bars on chain saws are specifically designed
to provide a guide track for saw chain and should never be used
as a pry bar or crow bar. Any twisting, turning or levering in the
cut will reduce the life of the bar rails. This will also void warranty
on the guide bar! (fig. 42)
CHAIN SAW CLEANING
After every cutting job, thoroughly clean the saw and inspect
for any damage. Important check points are chain brake system,
cooling air intake areas, cylinder cooling fins and air filter.
Caution! Always wear safety goggles when using
compressed air to prevent eye injury. Always use
environmentally friendly cleaning material available
from your specialist dealer. Do not clean chain saw
with fuel!
Chain Brake Maintenance (fig.44)
Operator Checks:
Periodically check for smooth functioning. Remove resin, chips
and other foreign matter. Apply grease or high temperature
resistant motor oil to visible joints.
Brake test:
- start engine
- engage brake while engine idles
– briefly accelerate to full throttle
– the chain should remain stationary
