Mounting the Bar and Chain

1 Unscrew nut and take off the sporcket cover.
2 Turn tensioning screw (1) anticlockwise until the ten-
sioning nut (2) butts against the left.
The chain is very sharp – wear work gloves to pro-
tect hands from cuts.
3 Fit the chain – start at the bar nose.
4 Fit guide bar over the stud (3). Engage peg of ten-
sioner slide in locating hole (4) – place the chain over
sprocket (5) at the same time.
5 Now turn tensioning screw (1) clockwise until there is
very little chain sag on the underside of the bar – and
the drive link tangs are located in the bar groove.
6 Refit the sprocket cover and screw on the nut only fin-
gertight.

Tensioning the Saw Chain

Retensioning during cutting work:
• Shut off the engine and then slacken the nut.
• Hold the bar nose up.
• Use screwdriver to turn the tensioning screw (1) clock-
wise until chain fits snugly against the underside of
the bar.
Tighten down the nut firmly.
A new chain has to be retensioned more often than one
that has been in use for some time – check chain ten-
sion frequently – see chapter „Operating
/ During Operation".
• Check chain tension.

Checking Chain Tension

• Shut down the engine.
• Wear work gloves to protect hands.
• Chain must fit snugly against the underside of the bar
and it must still be possible to pull the chain along the
bar by hand.
• If necessary, retension the chain.

Chain Lubricant

For automatic and reliable lubrication of the chain
and guide bar – use only an environmentally
compatible quality chain and bar lubricant with
non-fling additive is recommended.
The service life of the chain and guide bar depends on
the quality of the lubricant. It is therefore essential to
use only a specially formulated chain lubricant. If special
chain lubricant is not available, you may – in an emergen-
