Chain Sharpening
Chain File:
3.96mm (5/32”)
Chain Pitch:
9.53mm (3/8”)
Chain Guage:
1.3mm (0.050”)
Sharpen the chain regularly to maintain optimum
performance of the saw. Signs of a dull chain are:
• The sawdust becomes powder-like
• Extra force is required to execute a cut
• The cut does not track in a straight line
• Increased vibration
• Increased fuel consumption
Warning!
Wear heavy gloves when handling the chain. Hold the guide bar securely
in a vice.
Sharpen each cutter using a chain file. Always use outward strokes. After sharpening,
the cutters must all have the same width and length.
After every 3-4 times use an authourised repair centre to professionally sharpen your
saw chain. They have the special tools necessary to ensure the correct cutting angles
and depths.
Guide bar wear
Reverse the guide bar every 8 working hours to ensure uniform wear. Check the bar rails
frequently and if necessary remove burs and square-up the rails using a flat file.
Adjusting the carburettor
The carburettor is factory set and should not require adjustment.
Changes in operating conditions may require fine tuning of the carburettor. A special tool
is required for making these adjustments. Contact Ozito Customer Service for advice
and instructions.

1. Loosen the filter cover knob and remove the filter over.
2. Remove the air filter.
3. Split the air filter into its two halves and clean the mesh.
Dry particles can be removed by tapping on a hard surface.
More stubborn dirt may require washing out the filter with
petrol or using an air compressor.
4. Re-assemble the two halves and replace the airfilter,
filter cover and filler cover knob.
NOTE:
Before cleaning your chainsaw or carrying out any maintenance procedure,
make sure that the engine is off and is cool. Disconnect the spark plug to prevent
accidental starting

5. Take off the guide bar and maintain it as follows,
remove any saw dust from the groove in the guide bar.
6. Make sure that the oil port is not clogged. Grease the
nose sprocket at the tip of the guide bar.
7. Check for fuel and oil leakage and loose fastenings,
especially those securing the handles and the guide bar.
8. Clean any dust away from the cooling vents as
clogged vents can cause overheating.
NOTE:
The front guard (chain brake) must be disengaged to
remove the chain drive cover, guide bar and chain.
Pruning is the removal of a limb or branch
from a standing tree.
Felling a tree
Decide the direction in which you wish the
tree to fall taking into account the direction
of the wind, the position of branches, lean
of the tree, ease of subsequent limbing
and bucking and other factors prevalent
at the time.
WARNING!:
Felling a tree should only be done by
trained operators.

Limbing
WARNING!:
Always keep a balanced stance. Do not
stand on the log. Be alert to the fact that the log may roll
over. When working on a slope, always stand on the up
hill side of the log.
Limbing is the process of removing the
branches from a fallen tree. Check the
direction in which a branch will bend before
cutting it. Always cut on the opposite side
to the bending direction so that the guide
bar is not pinched in the cut. For large limbs
that cannot be removed in one cut, make an
initial cut from the bent side and finish by
sawing from the opposite direction. Do not remove limbs that are supporting
the fallen tree on the ground until the tree has been cut into lengths.

Bucking
Bucking is cutting a log into lengths for
easier handling.To saw a log lying on the
ground, first saw halfway, then roll the log
over and cut from the opposite side.
To saw the end of a log supported off the
ground, first saw up from the bottom
one-third through the log then finish by sawing down from the top. To saw
a log in the middle of two supports holding it off the ground, first saw down
from the top one-third through the log then finish by sawing up from the
bottom.
CAUTION!:
Avoid cutting into the ground as this will very
quickly dull the saw chain.
Pruning
WARNING!:
Do not use an unstable foothold or ladder.
Do not overreach. Do not saw above shoulder height.
Always use both hands to hold the saw. First cut up
from the bottom and finish down from the top.
