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.
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.
Chain Sharpening
Chain File:
3.96mm (5/32”)
Chain Pitch:
9.53mm (3/8”)
Chain Gauge:
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
Sharpen each cutter using a chain file. Always use outward strokes and maintain
a 30
°
angle between the chain and file. After sharpening, the cutters must all
have the same width and length.
After every 3-4 uses get an authorised repair centre to professionally sharpen
your 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 guide rails frequently and if necessary remove burrs and square up the rails
using a flat file.
Maintenance to be performed after each use

NOTE:
THE CHAIN BRAKE MUST BE OFF/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.

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.

CAUTION!:
AVOID CUTTING INTO THE GROUND AS
THIS WILL VERY QUICKLY DULL THE SAW CHAIN.

WARNING!:
DO NOT USE AN UNSTABLE FOOTHOLD

ABOVE SHOULDER HEIGHT. ALWAYS USE BOTH
HANDS TO HOLD THE SAW. FIRST CUT UP FROM THE

MAINTENANCE
WARNING!:
WEAR HEAVY GLOVES WHEN HANDLING
THE CHAIN. HOLD THE GUIDE BAR SECURELY IN A
VICE.
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
1.
Loosen the filter cover
knob and remove the
filter cover.
2.
Remove the air filter.
4.
Re-assemble the two halves and replace the airfilter, filter cover and
filter cover knob.
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.
To maintain the guide bar:
5.
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.
