ly. To assemble, first remove the protective cap (10),
unscrew the hexagon head cap screw underneath
and detach the chain cover (9). To prevent injury on
the sharp cutting edges, always wear gloves when
assembling, tensioning and checking the chain.
Before assembling the chain bar with the saw
chain, check the cutting direction of the teeth
(see Fig. 2)!
Hold the chain bar (11) vertically with
the tip pointing upwards and put on the saw chain
(12), beginning at the tip of the bar.
Then assemble
the chain bar and saw chain as follows:
Place the chain bar with saw chain on the sword
guide (B) and chain tensioning bolt (A). Fit the saw
chain round the chain wheel (D) and make sure the
chain is correctly mounted (see Figure 2/Item 12).
Place the cover (9) on top and tighten gently with the
hexagon nut.
8. Tensioning the saw chain
Always pull out the power plug before doing any
work on the machine!
Wear safety gloves!
Make sure that the saw chain (12) is inside the guide
groove of the chain bar (11)! You can now tension
the chain correctly by turning the chain tensioning
screw (E) clockwise (turning it anticlockwise may
loosen the chain). Then tighten the hexagon nut.
Check the chain tension again (see Fig. 10).
Do not
tension the saw chain too tightly. When cold, it
should be possible to lift the chain in the middle of
the chain bar approx. 3 mm. When warm, the saw
chain will expand and slacken. There is a danger of
the saw chain jumping off the rail altogether.
Retension if necessary. If the saw chain is reten-
sioned when hot, it must be loosened again when
the sawing work has been completed. Otherwise, the
contraction which takes place as the chain cools
would result in excessively high tension. A new saw
chain requires a running-in period of approx. 5 min-
utes. Chain lubrication is very important at this stage.
After running in, check the chain tension and reten-
sion if necessary.
9. Filling with chain oil (see Fig. 9)
To prevent dirt getting inside the tank, clean the oil
tank cap (3) before opening. Check the contents of
the oil tank during sawing work by checking the oil
gauge (A). Close the oil tank cap (3) tightly and wipe
away any spills.
10. Chain lubrication
To prevent excessive wear, the saw chain and chain
bar must be evenly lubricated during operation.
Lubrication is automatic. Never work without chain
lubrication. If the chain runs dry, the entire cutting
apparatus will quickly become severely damaged. It
is therefore important to check both chain lubrication
and the oil gauge before every use (Fig. 9).
Never use the saw when the oil level is below the
„Minimum“ mark (Fig. 9).
앬 Minimum - When only approx. 5 mm of oil is visi-
ble at the lower rim of the oil gauge, you must
top up with oil.
앬 Maximum - Top up with oil until the window is
full.
11. Checking the automatic lubrication
Before commencing work, check the automatic chain
lubrication and oil gauge. Switch on the chainsaw
and hold it above light-colored ground. Be careful not
to allow the chainsaw to touch the ground. For safety
reasons it is best to keep a clearance of at least 20
cm. If you now see growing traces of oil, the chain
lubrication system is working correctly. If there are
no traces of oil at all, try cleaning the oil outlet (Fig.
3/Item C) or contact your Customer Service.
12. Chain lubricants
The service life of saw chains and chain bars
depends to a large extent on the quality of the lubri-
cant used. Old oil must not be used! Use only envi-
ronment-friendly chain lubricant. Store chain lubri-
cant only in containers which comply with the
regulations.
13. Chain bar
The chain bar is subject to especially severe wear
and tear at the nose and on the bottom. To avoid
one-sided wear and tear, turn the chain bar over
every time you sharpen the chain.
14. Chain wheel
The chain wheel ( Fig. 2/Item D ) is subject to espe-
cially high wear and tear. If you notice deep wear
marks on the teeth, the chain wheel must be
