CUTTING THE LIMB OF A FALLEN TREE (Fig.20)
Before starting work, check the direction of bending force inside the log to be cut. Then
make the initial cut from the bent side (Fig.20 No.1) and finish by sawing from the opposite
side (Fig.20 No.2). Always finish cutting from the opposite side of bending direction to
prevent the guide bar from being caught in the cut.
WARNING: When cutting a limb that is under tension, be alert for spring back so that you will
not be struck when the tension in the wood fibres is released.
MAINTAINANCE AND SERVICING
Always disconnect the plug when carrying out maintenance and servicing.
In order to maintain your chainsaw in proper working order, perform the maintenance and
checking operations described in this manual at regular intervals. Leave all maintenance other
than the items listed in the Owner’s Manual to your competent servicing dealer. Repairs and
servicing must only be performed by authorised dealers and service agents.
Always remove wood shavings and oil from the chainsaw after use. Ensure that the motor
ventilation slots in the housing of the chainsaw are clear of dirt (if blocked there is danger of
overheating).
Remove the chain and clean it if it is dirty, e.g. gumming with resin. Place the chain in a
vessel containing chain cleaner. There-after clean the chain with clean water. If the chain is
not used again immediately, it must be treated with oil or a custom anti-corrosion spray.
Check all the chainsaw parts for wear after every use. In particular the chain, bar and
sprocket.
Ensure that the chain tension is correct. If the chain is too loose, it may come off during use
and lead to injuries. The chain must be replaced immediately if it is damaged. The cutting
teeth must be at least 4 mm long.
Check the motor housing and power cable after every use for damage. If there is any sign of
damage, have the chainsaw checked by an authorised service agent.
Check the oil level and lubrication after every use. Insufficient oil and lubrication leads to
damage to the chain, bar and motor.
Check the sharpness of the chain every time before you use the chainsaw. A blunt chain will
cause over-heating of the motor.
Sharpening a chain requires experience and specialised knowledge. We therefore
recommend that sharpening be carried out by a specialised workshop.
Guide bar
When the guide bar is dissembled, remove sawdust in the bar groove and the oiling port.
Grease the nose sprocket from the feeding port on the tip of the bar (Fig. 13).
Sprocket
Check for cracks and for excessive wear interfering with the chain drive. If wearing is observed,
replace. Never fit a new chain on a worn sprocket, or a worn chain on a new sprocket.
SAW CHAIN
WARNING: It is very important for smooth and safe operation to keep the cutters sharp.
Your cutters need to be sharpened when
Sawdust becomes powder-like
You need extra force to saw in
The cut does not go straight
Vibration increases
