(Pressing in the lever leads to the fitting of lever into the
nut.) (Fig. 12)
Turn the adjusting dial to adjust saw chain tension. Grasp
the saw chain in the middle of the guide bar and lift up.
The gap between the guide bar and the tie strap of the
saw chain should be approx. 2 - 4 mm. If the gap is not
approx. 2 - 4 mm, slightly turn the adjusting dial which
secures the guide bar. At this time, adjust with the tip of
guide bar slightly pointing up. (Fig. 13)
With the lever depressed, turn it fully clockwise to tighten
the nut firmly. (Fig. 14)
Return the lever to its original position. (Fig. 15)
CAUTION:
• Excessively high tension of saw chain may cause
breakage of saw chain, wear of the guide bar and
breakage of the adjusting dial.
• Installing or removing saw chain should be carried out
in a clean place free from sawdust and the like.
OPERATION
Lubrication
CAUTION:
• Always be sure that the tool is switched off and
unplugged before lubricating the saw chain.
Lubricate the saw chain and bar using a biologically
degradable saw chain oil with an adhesion agent. The
adhesion agent in the saw chain oil prevents the oil from
being thrown off the saw excessively quickly. Mineral oils
must not be used, as they are harmful to the environment.
(Fig. 16)
CAUTION:
• Prevent the oil from coming into contact with the skin
and eyes. Contact with the eyes causes irritation. In the
event of eye contact, flush the affected eye immedi-
ately with clear water, then consult a doctor at once.
• Never use waste oil. Waste oil contains carcinogenic
substances. The contaminants in waste oil cause
accelerated wear of the oil pump, the bar and the
chain. Waste oil is harmful to the environment.
• When filling the chain saw with chain oil for the first
time, or refilling the tank after it has been completely
emptied, add oil up to the bottom edge of the filler neck.
The oil delivery may otherwise be impaired.
Clean the area around the oil filler cap shown in the figure
thoroughly to prevent any dirt from entering the oil tank.
(Fig. 17)
Unscrew the oil filler cap and add oil up to the lower edge
of the filler neck.
Screw the oil filler cap firmly back in place.
Wipe away any spilt chain oil carefully.
When the chain saw is used for the first time, it may take
up to two minutes for the saw chain oil to begin its lubricat-
ing effect upon the saw mechanism. Run the saw without
load until it does so (see "CHECKS").
The tank capacity (200 ml) is sufficient for approximately
30 minutes' use.

CHECKS
Before starting work, carry out the following checks:
Checking the chain tension (Fig. 18)
WARNING:
• Always withdraw the mains plug before checking the
The saw chain is correctly tensioned when it is in contact
with the underside of the bar and can be raised approxi-
mately 2 - 4 mm from the bar by light finger pressure.
Check the chain tension frequently, as new chains are
subject to elongation. A chain which is too slack can jump
off the bar, and therefore presents an accident risk.
If the chain is too slack: Refer to the section titled "Adjust-
ing saw chain tension" and adjust the saw chain tension
again.
Checking the switch action
CAUTION:
Always unplug the tool before testing the switch trigger.
Locking the switch trigger in the ON position is prohibited.
It must not be possible to depress the switch trigger
unless the lock-off button is first depressed.
The switch trigger must not jam in the depressed position.
When released, the switch trigger must return automati-
cally to the OFF position, and the lock-off button must
return to its original position. (Fig. 19)
Checking the chain brake
NOTE:
• If the chain saw fails to start, the chain brake must be
Hold the chain saw with both hands when switching it on.
Hold the rear handle with your right hand, the front handle
with your left. The bar and the chain must not be in con-
tact with any object.
First press the lock-off button, then the switch trigger. The
saw chain starts immediately.
Press the hand guard forwards using the back of your
hand. The saw chain must come to an immediate stand-
still. (Fig. 20)
CAUTION:
• Should the saw chain not stop immediately when this

Release the switch trigger completely. The saw chain
must come to a standstill within one second.
