Use for intended purpose
The chain saw Is intended for
- cutting logs, branches, sawn timber and similar material,
- trimming trees and for
- felling trees and cutting branches off felled or fallen trees.
The user bears sole responsibility for any damage or injury that may result from use of the tool for
any purpose other than thai for which It is Intended Generally accepted accident-prevention
regulations and the enclosed Safety instructions,, for the avoidance of accidents when working with
electric tools must be complied with.
Operating instructions
Operating voltage
Before putting the chain saw into operation, make sure that the voltage stated on the rating plate is the same as that of your
electricity supply.
Fixing name-plates
The saw is double insulated. If you want to fix a name-plate to the drill through the motor housing of the saw as this could nullify
the double-insulation safely feature.
Signification of the pictograms
The pictograms on the chain saw stand for:
Warning:
Risk of injury when working with the tool.
Read these Operating instructions and the enclosed * safety instructions " for the avoidance of accidents when working with
electric tools(red booklet) carefully and thoroughly before the chain saw is used for the first time.
Use ear protectors when Working with the saw.

The chain saw should not be used during rain, neither shoold It be left
outside by rainy weather.
Fitting the guide bar and Saw chain
If the chain saw is already connected To the power supply: pull the plug From the socket outlet.
Wear protective gloves whenever doing any work on the saw chain.

The chain must be so fitted over the guide bar that the cutting edges of the cutters (a) face in the direction
that the chain runs.
Hold the guide bar with the nose upwards and place the saw chain so on Unscrew the nuts(2)
and remove the drive-sprocket cover(lXsee the picture on the front page).
Bring the chain tensioning pin(12)into its extreme left-hand position(when viewing the tool as in
Fig.l)by turning the tensioning screw(9)anticlockwise as far as it will go.
The direction of rotation of the saw chain is indicated by two arrows on the drive-sprocket cover.
the bar that the teeth(b) on the nose sprocket of the guide bar engage in to the chain links and the bottom
sections of the drive links are situated in the groove of the bar.
Then put the saw chain round the drive Sprocket(13) and place the guide bar With its slot so onto the
threaded studs (11)that the chain tensioning pin(12) engages in the hole(15) in the bar.
Replace the drive-sprocket cover(l) and screw on the nots(2)bnt do not yet tighten them.
With the nose of the guide bar turned upwards turn the tensioning screw(12) clockwise to take up
any slack in the saw chain.
The chain is correctly tensioned when it is still
possible to raise it by 3-4 mm In the middle of the
guide bar
Fig 3
After tensioning the saw chain turn the nose of the bar upwards and tighten the nuts (2) firmly.
Lubricating oil for the saw chain
When the chain saw is supplied new, there is no oil in the oil container and so the container
mast be filled with chain-saw oil before starting up.
Use for the first filling the chain-saw oil supplied with the tool This oil is biologically
degradeable. It allows operating the chain saw at Low as -15 *C.
Never use waste oil for lubricating To top the saw up with lubricating oil When switching the
chain saw on, the unscrew the filler cap (3). Make sure hand-protection guard (6) must be in
that no dirt gets into the oil container its normal position, i.e. be pressed in while filling up. The
oil level can be checked through the gauge glass (14).

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 thestrain- relief strap suppliedbetween the plugon the sawspower 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 barbeyond
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 anyrisk 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 firmhold of thetool, a secure footing and are sure that
the guide bar and saw chain are not touching anything.
