For switching off, release the on/off switch.
NOTE: The chain brake must be activated in order for
the saw to be switched on.
CHAIN BRAKE LEVER (See Fig. L)
The chain brake lever is a safety mechanism activated
through the front hand guard, when kickback occurs.
Chain stops immediately.
The following function check should be carried out at
regular intervals. Pull the front hand guard towards
the operator (position ) to deactivate chain brake.
To activate the chain brake, push front hand guard
forwards (position ).
NOTE: If the saw is unable to start, even though it is
assembled properly and working with fully charged
battery packs, then you should check if the chain brake
lever is in the correct position (position ).

cutting depending on sawing intensity and stops.
Check recent replaced chain tension about every 10
minutes during operation.
(1) Installing the battery pack into the machine.
(2) Make sure section of log to be cut is not laying on
the ground. This will keep the chain from touching
the ground as it cuts through the log.
Touching the ground while the chain is moving is
dangerous and will dull the chain.
(3) Use both hands to grip saw. Always use left hand to
grip front handle and right hand to grip rear handle.

(5) When ready to make a cut, push the lock-out button
completely in with the right thumb and squeeze the

will turn the saw off. Make sure the saw is running
at full speed before starting a cut.
(6) When starting a cut, slowly place moving chain
against the wood. The wood should be as close to

to avoid possible bouncing or skating (sideways

(7) Guide the saw using light pressure and do not put
excessive force on the saw, letting the saw do its
work. The motor will overload and can burn out. It
will do the job better and safer at the rate for which
it was intended.
(8) Remove the saw from a cut with the saw running
at full speed. Stop the saw by releasing the on/off

Kickback Safety Devices On This Saw
This saw has a low-kickback chain and reduced
kickback Guide Bar. Both items reduce the chance of
kickback. However, kickback can still occur with this
saw.
The following steps will reduce the risk of kickback.
Use both hands to grip saw while saw is running.

around saw handles.
Keep all safety items in place on saw. Make sure
they work properly.
Do not overreach or cut above shoulder height.
Keep solid footing and balance at all times.
Stand slightly to the left side of saw. This keeps
your body from being in direct line with chain.
Do not let Guide Bar nose touch anything when
chain is moving.
Never try cutting through two logs at same time.
Only cut one log at a time.
Do not bury the Guide Bar nose or try plunge cut
(boring into wood using guide bar nose).
Watch for shifting of wood or other forces that may
pinch chain.
Use extreme caution when reentering a previous
cut.
Use only the low-kickback chain and guide bar that
were supplied with this Chainsaw or recommended.
Never use a dull or loose chain. Keep chain sharp
with proper tension.
How to use Saw Safely
1. Use the Chainsaw only with secure footing.
2. Hold the Chainsaw at the right-hand side of your
body (See Fig. O).
3. The chain must be running at full speed before it
makes contact with the wood.
4. Use the bumper spikes to secure the saw onto the
wood before starting to cut.
5. Use the Bumper Spikes as a leverage point while
cutting. (See Fig. P)
6. Do not operate the Chainsaw with arms fully
