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 tension
frequently – see chapter „Operating
ing 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
• If necessary, retension the chain.

Chain Lubricant

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-
cy – use an HD single grade or multigrade engine oil with
a viscosity that suits the prevailing outside temperature.

Filling Chain Oil Tank

• Thoroughly clean the filler cap and area around it so

• Position the unit so that the filler cap faces up.
If the oil level in the tank does not go down, the reason
may be a problem in the oil supply system: Check chain

and it must still be possible to pull the chain along the
bar by hand.
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.
Do not use waste oil!
Medical studies have shown that renewed contact
with waste oil can cause skin cancer. Moreover,
waste is environmentally harmful!
Waste oil does not have the necessary lubricating
properties and is unsuitable for chain lubrication.

Never allow the oil tank to run dry!
