8. CUTTING APPLICATIONS
APPLICATIONS
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.
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!:
AVOID CUTTING INTO THE GROUND AS
THIS WILL VERY QUICKLY DULL THE CHAIN.
Limbing
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.
Pruning
WARNING!
DO NOT USE AN UNSTABLE FOOT-HOLD 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.
Pruning is the removal of a limb or
branch from a standing tree.
Chain Tension
Check the chain tension frequently and adjust as often as necessary. (see Tensioning the chain)
Maintaining the Guide Bar
Most guide bar problems can be prevented by
keeping the chainsaw well maintained. Insufficient
guide bar lubrication and operating the saw with
a chain that is TOO TIGHT will contribute to rapid
bar wear.
To help minimize bar wear, the following guide bar
maintenance procedures are recommended.
• The bar should be reversed every 8 working
hours to ensure uniform wear. Keep the bar
groove and lubrication hole clean.
• Check the bar rails frequently for wear and, if necessary, remove the burs and square-up the
rails using the flat file.
• Oil passages on the bar should be cleaned to ensure proper lubrication of the bar and chain
during operation. Grease the nose sprocket at the tip of the guide bar.
Note:
The condition of the oil passages can be easily checked. If the passages are clear, the
chain will automatically give off a spray of oil within seconds of starting the saw. Your saw is
equipped with an automatic oiler system.
Chain Sharpening
Chain File: 3.96mm (5/32”)
Chain Pitch: 9.53mm (3/8”)
Chain Gauge: 1.3mm (.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
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.
WARNING!
ENSURE THE TOOL IS TURNED OFF AND
DISCONNECTED FROM THE POWER SUPPLY BEFORE
PERFORMING ANY OF THE FOLLOWING OPERATIONS.
WARNING!
ALWAYS WEAR HEAVY GLOVES WHEN
HANDLING THE CHAIN AS IT IS VERY SHARP AND CAN
CUT YOU WHEN IT IS NOT MOVING.
WARNING!
WEAR HEAVY GLOVES WHEN HANDLING
THE CHAIN. HOLD THE GUIDE BAR SECURELY IN A
VICE.
MAINTENANCE
WARNING!
KICKBACK MAY OCCUR WHEN THE NOSE
OR TIP OF THE GUIDE BAR TOUCHES AN OBJECT, OR
WHEN THE WOOD CLOSES IN AND PINCHES THE SAW CHAIN
IN THE CUT. TIP CONTACT IN SOME CASES MAY CAUSE A
LIGHTNING FAST REVERSE REACTION, KICKING THE GUIDE
BAR UP AND BACK TOWARDS THE OPERATOR.
