10 OPERATION
10.1 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.
10.2 Running the saw chain in
Before starting 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.
10.3 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.
10.4 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).
