Chain brake
The chain brake is a protective mechanism which in case
of a stroke back chain saw is initiated via the front hand
protection or after releasing the on/off switch. The saw
chain stops immediately (< 0.1 sec.).
Checking the chain brake
Check the chain brake's proper function before each
work start.
Start the engine.
Hold the chain saw with both hands.
Use the back of your hand to press
against the front hand guard (13).
The chain saw must stop immediately.
It is not allowed to use this chain saw without
properly working chain brake. Please contact the
manufacturer or the customer service point.
Saw chain
Before checking/clamping the saw chain
- switch off the device
- apply the chain brake.
- pull out main plug
- in order to avoid injuries wear protective
gloves.
Check the saw chain tension before
start of work
after the first steps
during sawing regularly all 10 minutes
Only with a correct clamped saw chain and a sufficient
lubrication you can influence the durability.
Please observe the following:
a new saw chain must be reclamped more often until it has
elongated.
in case of heating of chain to operating temperature it
expands and needs to be reclamped.
After finishing the sawing works release tension of
saw chain as in case of cooling too high tensions would
emerge in the saw chain.
if chain flackers or comes out of the guide clamp it again
immediately.
Clamping of saw chain
Loosen the retaining nut (3) by max. 1 turn.
Slightly lift the guide bar tip and turn the chain stretching
screw (4) clockwisely until the correct chain tension is
reached.
The saw chain is correctly clamped when it can be lifted in
the centre of the guide bar by appr. 3 – 4 mm.
Turn the chain stretching screw (4) anti-clockwise when
the saw chain is stretched too much.
Check wether the chain links are positioned correctly in
the guide slot of the guide bar.
Re-tighten the retaining nut (3).

Chain lubrication
Never operate the chain saw without functioning chain
lubrication.
Check the function of the automatic chain lubrication by
switching on the chain saw and holding it with the pike in
direction of a carton or paper on the ground.
Checking of the oil automatic
Do not get in contact with the ground with the chain. Keep
a safe distance of 20 cm.
If an increasing oil track is caused when checking it the oil
automatic works faultless.
If there is no oil track despite full oil tank
Clean the oil flow canal (G) and the upper chain clamping
boring (H).
Pay attention during assembly that the seal (7) for the
oil flow channel has been inserted.
If this is not successful please contact the customer
service.
Working instructions
Before starting any work ensure the following
The "safety instructions"
following additional working instructions
Carry out the following checks before the initiation and
regularly during the working process. Observe the relevant
sections in the operating instruction manual:
Before starting to work
Is the chain saw assembled completely and properly?
Is the chain saw in good and safe condition?
Only use a suited guide bar/saw chain combination as
described under "Technical data". Incorrect combinations
increase the risk of kickbacks.
Is the oil tank filled (chain lubrication)?
Check the oil level on a regular basis. Top up saw chain
oil without delay to prevent the saw chain from running dry.
Is saw chain clamped correctly?
Observe the points in paragraph "Clamping saw chain".
Is saw chain sharpened correctly?
Use only well sharpened saw chains as edgeless saw
chains increase not only the risk of backstrokes but also
charge the motor.
Is chain brake released and works properly?
Observe the points in paragraph "Checking the chain brake".
Are the handles clean and dry – free of oil and resin?
Do you wear the required protective equipment?
Before starting your work make sure that:
no other persons, children or animals stay within the
working area,
you can always step back without any barriers,
your standing area is free from foreign objects,
brushwood and branches,
you have always a secure standing position.
