Overview of safety features and methods for returning the machine to operation:
Type of safety feature
Low accumulator voltage
(indicated on the accumulator)
Machine overload (machine
was switched off due to recoil
or excessive load)
Overheating (critical temper‑
ature of the motor, the elec‑
tronics or the accumulator was
reached)
10.1 Start-Up Electronics
The machine features a gradual start up function. The machine
will reach maximum speed in approx. 1.5 s.
ATTENTION!
The machine must not be under load
(cutting) during gradual start up! Allow the machine
to reach full speed before cutting.
11 Safety devices on your electric
chainsaw
11.1 Chain Brake
The chainsaw is fitted with a mechanical chain brake. Should the
saw swing back as a result of impact onto a solid object, the saw
chain's drive immediately stops, due to the response of the hand
guard [4]. A braking action is initiated when the back of the hand
on the front handle [2] pushes forward onto the hand guard [4]
(position B). You should always check the functioning of the
chain brake before using the saw!
ATTENTION!
When releasing the chain brake, pull
the hand guard [4] backwards in the direction of the
handle and fix it here (position A). The switch [9] may not
be activated! Make sure that before putting the chain saw
into operation the hand guard [4] is fixed in the working
position.
11.2 Runout brake
In accordance with relevant regulations this chainsaw is equipped
by the runout brake. it is connected with the chain brake and
brakes the running chain after the chainsaw was switched off. It
is activated after release of the switch [9]. This runout brake elimi‑
nates the risk of injury by the running chain.
11.3 Chain catcher
This chainsaw is equipped by the chain catcher [17]. If the chain is
broken during work, the catcher catches quickly the moving chain
end thus preventing injury of the user's hand.
12 Before Commissioning
12.1 Oil tank filling
The chainsaw may never work without the oil, because lack of oil
can lead to damage of the chain, bar and engine. Damage as the
consequence of work without oil is not covered by the warranty.

mulator

ATTENTION!
Be so kind and use only the oil suitable
for the saw chains.
Bio oil NAREX CO 1l (ord. no. 65403576) can be purchased in spe‑
cialised shops. Do not use any worn out oil. Doing so would dam‑
age your chainsaw and void the warranty.
ATTENTION!
Before doing any work on the machine
(maintenance, cleaning, adjustment, etc.), remove
both accumulators from the machine!
» Unscrew the cap [3]. The cap is fitted from the inside with
a plastic tether with a retainer to prevent the loss of the cap.
» Pour lubricating oil into the tank, but no more than up to the
upper level of the inspection window (oil mark) [1] and tight‑
en the cap tightly.
ATTENTION!
When pouring oil, do not fill the tank to
the brim.
» Empty the oil tank before transporting the chainsaw!
» Check that the chain lubrication system is functional before
you begin work. Turn the chainsaw on when the cutting
mechanism is installed and hold it at sufficient distance from
a light‑coloured, contrasting surface. The chain bar must not
be in contact with the surface! If the chain leaves an oil mark,
the lubrication system is working properly.
» After finishing your work, place the chainsaw horizontal‑
ly onto a absorptive underlay. Several drops of oil may drip
down, due to the distribution of oil across the bar, chain and
engine.
» Always empty the oil tank before long‑term storage.
12.2 Mounting the Guide Bar and Chain
ATTENTION!
Risk of injury. Wear protective gloves
while fitting the chain.
ATTENTION!
Before doing any work on the machine
(maintenance, cleaning, adjustment, etc.), remove
both accumulators from the machine!
No tools are needed to mount the guide bar and chain onto
this chainsaw!
» Place the chainsaw on a stable surface.
» Loosen the manual clamping nut [7] by turning it anti‑clock‑
wise.
» Remove the sprocket wheel cover [8].
» Place the chain onto the guide bar and make sure to observe
the correct orientation relative to the direction of movement.
The teeth on the top side must be facing forward (see figure).
» Place the loose end of the saw chain onto the chain drive
sprocket [21].
» Fit the guide bar so that the horizontal opening in the bar fits
onto the mounting bolt [20] and guide bar stud [16].
» Make sure the chain tensioning pin [19] is fitted properly in
the opening in the bar. It must be clearly visible through the
opening. If needed, turn the ribbed wheel of the chain ten‑
sioning system [18] to move the pin forwards or backwards
until it fits into the opening in the bar.
» Check that all of the segments of the chain are fitted tightly
onto the guide bar and that the saw chain is guided closely
around the chain drive sprocket [21].
» Fit the catch [8b] of the sprocket wheel cover [8] into the lock‑
in hole [8a] and press the cover on firmly.
