@
Warning! Always wear protective gloves when
working on your chainsaw.
@
Warning! Before performing any assembly
or maintenance on power tools, switch off and

Fitting the guide bar and chain. (fig. A - L)
Place the chainsaw onto a stable surface (fig. A).
u
Fully loosen the chain adjust locking knob (9) (fig. B).
u
Remove the chain cover assembly (10) (fig. C).
u
Turn the tension adjust ring (5) anti-clockwise as far as it
u
will go so the arrow on the tension adjust ring (5) lines up
with the marker on the chain cover assembly (13) (fig. D)
Place the chain (6) over the guide bar (7) making sure that
u
the saw chain cutters on the upper part of the guide bar
(7) face towards the front (fig. E).
Guide the chain (6) around the guide bar (7) and pull it to
u
create a loop to one side at the rear end of the guide bar
(7).
Guide the chain (6) around the drive sprocket (14). Place
u
the guide bar (7) onto the bar location studs (15) (fig. F &
G).
Place the chain cover assembly (10) onto the chainsaw
u
(fig. H) making sure the arrows are aligned (fig. I).
Turn the chain adjust locking knob (9) clockwise to attach
u
the chain cover assembly (10) and lightly tighten (fig. I).
Turn the chain adjust locking knob (9) 180 degrees anti-
u
clockwise to release the tension (fig J).
Turn the chain tension adjust ring (5) clockwise until the
u
chain (6) is tight. Make sure that the chain (6) is snug
around the guide bar (7) (fig. K).

(Original instructions)
Check the tension as described below. Do not overtighten.
u
Tighten the chain adjust locking knob (9) (L).
u
Checking and adjusting the chain tension (fig. K)
Before use and after every 10 minutes of use, you must check
the chain tension.
Remove the battery (12).
u
Lightly pull on the chain (6) as shown (inset fig. K). The
u
tension is correct when the chain (6) snaps back after
being pulled 3 mm away from the guide bar (7). There
should be no "sag" between the guide bar (7) and the
chain (6) on the underside.
Note: Do not over-tension the chain as this will lead to
excessive wear and will reduce the life of the guide bar and
the chain.
Note: When the chain is new, check the tension frequently
(after disconnecting from the mains) during the first 2 hours of
use because a new chain stretches slightly.
To increase the tension (fig. J, K & L)
Turn the chain adjust locking knob (9) 180 degrees anti-
u
clockwise to release the tension. (fig. J)
Tension the chain using the chain tension adjusting ring
u
(5), turn clockwise to tighten (fig K).
Tighten the chain adjust locking knob (9) (fig. L).
u
Fitting and removing the battery (fig. M)
To fit the battery (12), line it up with the receptacle on the
u
tool. Slide the battery into the receptacle and push until
the battery snaps into place.
To remove the battery, push the release buttons (16) while
u
at the same time pulling the battery out of the receptacle.
Use
Warning! Let the tool work at its own pace. Do not overload.
Charging the battery (fig. N)
The battery needs to be charged before first use and whenev-
er it fails to produce sufficient power on jobs that were easily
done before. The battery may become warm while charging;
this is normal and does not indicate a problem.
Warning! Do not charge the battery at ambient temperatures
below 10 °C or above 40 °C. Recommended charging tem-
perature: approx. 24 °C.
Note: The charger will not charge a battery if the cell
temperature is below approximately 10 °C or above 40 °C.
The battery should be left in the charger and the charger
will begin to charge automatically when the cell tempera-
ture warms up or cools down.
