Starting cycles generate brief voltage drops. Interference with other equipment/machines may occur in case of unfavourable
mains system conditions. Malfunctions are not to be expected for system impedances below 0.25 ohm.

That the declared vibration total value(s) and the declared
noise emission value(s) have been measured in accordance
with a standard test method any may be used for comparing
one tool to another.
That the declared vibration total value(s) and the declared
noise emission value(s) may also be used in a preliminary as-
sessment of exposure.
That the vibration and noise emissions during actual use of
the power tool can differ from the declared values depend-
ing on the ways in which the tool is used especially what kind
of workpiece is processed; and of the need to identify safety
measures to protect the operator that are based on an estim-
ation of the exposure measures in the actual conditions of
use (taking account of all parts of the operating cycle such as
the times when the tool is switched off and when it is running
idle in addition to the trigger time).
Assembly
Mounting and Tensioning the Saw Chain (see
figures B1 – B4)
u
Do not use any tools for assembly.
u
Check the chain tension regularly during use. Using
the chainsaw with a misaligned or incorrectly tensioned
chain can result in chain breakage, kickback and/or in-
jury.
u
Upon initial operation, new chains can lengthen con-
siderably.
u
Avoid tensioning the chain if it is hot, as this will cause
the chain to become overtensioned and fit too tightly
against the chain bar when it cools down.
– Place the chain saw on any suitable flat surface.
– Make sure that the affixed tensioning wheel
(19) on the
chain bar has been fully rotated anticlockwise.
– Slide the saw chain (18) in the slot around the chain bar
(17) .
– Ensure the saw chain is in the correct running direction by
comparing the saw chain with the rotation symbol (15) .
– Fit the chain links around the drive sprocket (3) and
mount the chain bar (17) onto the fastening bolt (10) .
– Check if all parts are seated properly and hold the chain
bar and the chain in this position.
– Then rotate the affixed tensioning wheel (19) clockwise
until the chain is partly tensioned and will stay mounted
to the chain saw.
– Attach the cover (25) and rotate the clamping knob (24)
clockwise until the cover is partly secured.
– Turn the chain-tensioning ring (23) clockwise until the
correct chain tension is reached. When adjusting with the
chain-tensioning ring
(23) , make sure to hold the clamp-
ing knob (24) to prevent it from turning and clamping too
early.
– The saw chain (18) is correctly tensioned when it can be
raised approx. 2–3 mm from the chain bar in the centre.
This should be done by using one hand to raise the saw
chain against the weight of the machine.
– Once the correct tension is reached, hold the chain-ten-
sioning ring (23) and rotate the clamping knob (24)
clockwise until it is firmly secured.
– If the chain is tensioned too tightly, unscrew the clamping
knob (24) and repeat the steps for tensioning.
– The ratchet mechanism of the clamping system prevents
the chain from loosening. If the chain-tensioning ring (23)
is hard to rotate, loosen the clamping knob (24) by turn-
ing it anticlockwise.
Operation
The saw chain is automatically lubricated with chain oil dur-
ing operation via the oil outlet
(7) .
The chain saw is not supplied filled with oil.
Be sure to fill the chain saw with chain oil before using it.
It is important to use only biodegradable chain lubricants
(according to RAL-UZ 48) to avoid damage to the chain saw.
