By means of the set screw (4) it is possible to vary the quantity of oil delivered, When sawing
hard and dry timber and when using the entire useful length of the guide bar, set the screw to
"+" For sawing soft and wet timber (or when the guide bar is only partially side of the switch
handle, then in action) the oil-flow rate may be reduced by turning the screw in the direction of
the "-"sign.
Depending on the ambient temperature and the set rate of oil flow, it's possible to work for 15
to 40minutes with one filling of the oil container. (The capacity of the container is 0.2 litres.)
Power-supply connection
The chain saw has purposely been fitted with a comparatively short power lead to reduce the
risk of the lead being cut by the saw chain while working with the tool.
It is best to fit the strain- relief strap supplied between the plug on the saws power lead and the
coupler socked on the extension cord, to prevent the plug from being unintentionally pulled
out of the coupler socket. Before plugging the extension cord into the supply socket check the
cord for dajmage and deterioration. Never Operate the chain saw if the suppy Lead is not in
perfect order.
The electricity supply the chain saw is Connected to should be provided with An earth leakage
or residual current of not more than 30Ma.
Switching on and off
When switching the chain saw on, the Hand-protection guard(6) must be in its normal
position, i.e. be pressed in the direction of the arrow in Fig, 1 against the handle {5}.
The saw is provided with a safety device to prevent it being switched on accidentally. To
switch on
-grasp the handle (5) with the left hand .
-with the thumb of the right hand push the locking button at the left side of the switch
handle,then
- with the locking button still depressed, squeeze the trigger and
- release the locking button.
To switch off release the trigger. (The locking button returns into the locked position.)
The noise that the chain saw not being fitted with the guide bar and chain makes while the tool is running
down, is quite natural and has no ill effect on the function or service life of the saw.
Running the saw chain in
Before stating to saw, a new saw chain should be run in for 2-3 minutes and then its tension should be
checked as detailed under Fitting the guide bar and saw chain,, and the chain be re-tensioned if necessary.
Checking the chain lubrication
Running the saw chain without chain lubrication will quickly damage the chain and the guide bar beyond
repair and so you should always check the oil level before starting up.
Never run the saw without chain lubrication.
TO check the lubricating system switch on the chain saw and hold it with the guide bar and chain above
some light coloured area (an open newspaper will. A steadily increasing stain caused spray shows that the
lubricating system is working properly.
Chain brake
The saw is fitted with a chain brake that brings the saw chain to a stop a tenth of a second
- if the hand-protection guard (6) is brought into the tripping position
- -either manually or.
- while operating the chain saw, as a result of a kickback, by the back of the operator's hand or
- if the chain saw is switched off by releasing the trigger.
When the chain brake has been tripped by actuating the hand-protection guard (6), do not run the
Motor of the saw unnecessarily long. Set the guard immediately back to its normal position.
Before starting any work with the chain saw, be sure to check the proper functioning of the Chain
brake (by actuating the hand-protection guard and by releasing the trigger).
Particular safety precautions when working with the chain saw
When working with the chain saw, protective gloves, suitable shoes, leg protectors, eye protectors
and ear protectors should be used.
If the work involves any risk of head injury, a safety helmet must be worn When cutting down trees
and cutting and cutting off branches of felled or fallen trees, in addition a face protector should be
worn.
Always pull the plug from the socket outlet before attempting to check or adjust the chain or to
correct some fault and whenever moving one workplace to another.
Never switch on the chain saw unless you have a firm hold of the tool, a secure footing and are sure that
the guide bar and saw chain are not touching anything.
