- Turn the chain tightener (G/6) to the right (clockwise)
until the chain engages the guide groove of the bottom side
of the bar (see circle). Press the guide bar against the
housing with your left hand.
- Replace the sprocket guard (H/4).
- Manually tighten the retaining nuts (H/3).
Checking the chain tension
- The tension of the chain is correct if the chain rests against
the bottom side of the guide bar and can still be easily
turned by hand. While doing so the chain brake must be
released.
- Every new chain has to be broken in for about 2 to 3
minutes. Ample chain lubrication is essential during this
period. After breaking in, check chain tension and adjust, if
necessary.
- When checking the chain tension the engine must be
switched off.
NOTE: Check the chain tension frequently - chains tend to
get longer during use! If this is not done, there is a risk of the
chain jumping off the bar. It is recommended to use 2-3
chains alternatively.
In order to guarantee uniform wear of the guide bar the bar
should be turned over whenever replacing the chain.

Tightening the saw chain
- Slightly lift the end of the guide bar and turn the chain
adjusting screw (I/6) to the right (clockwise) until the chain
rests against the bottom side of the guide bar.
- While still holding up the tip of the guide bar, tighten the
retaining nuts (H/3) with the universal wrench.
STOP
Engaging the chain brake (braking)
If the kickback is strong enough the sudden acceleration of
the guide bar combined with the inertia of the hand guard
(L/3) will automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand guard
(L/3) forward (towards the tip of the saw) with your left hand (arrow 1).
Releasing the chain brake
Pull the hand guard (L/3) towards you (arrow 2) until you feel
it catch. The brake is now released.
