Clamping Of Saw Chain; Preparing For Startup; Chain Lubrication; Filling Up Saw Chain Oil - ATIKA BKS 38 A Manual Original

Clamping of saw chain

Risk of injury!
Stop the engine and wear protective
gloves whenever working on the guide
bar and on the saw chain!
Loosen the retaining nuts (14) by max. 1 turn.
Slightly lift the guide bar tip and turn the chain stretching
screw (15) clock wisely until the correct chain tension is
reached.
The saw chain is correctly stretched when it can be
lifted in the centre of the chain guide by appr. 3 – 4 mm.
Turn the chain stretching screw anti-clockwise when the
saw chain is stretched too much.
Check that the chain links are positioned correctly in the
guiding groove of the guide bar.
Re-tighten the locking nuts (14).
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 rest retched more frequently.
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.

P r e p a r i n g f
The chain saw is supplied without saw chain oil and
fuel filling.
Fill the saw chain as described under "Chain lubrication" and

"Fuelling".

Chain lubrication

Never operate the chain saw without lubrication. Any
use without chain saw oil may result in damage of the
chain saw and guide bar.
The durability and cutting power of the chain depends on the
optimal lubrication. During operation the saw chain is
automatically wetted with oil.

Filling up saw chain oil

Stop the engine and wear protective
gloves.
Avoid eye and skin contact.
Put the chain saw on a suitable base and unscrew the oil
tank lock (11).
Fill the oil tank with bio-degradable chain saw
adhering oil (order no. 400144). For easier filling use a
funnel.
When filling observe that no dirt reaches the oil tank.
Screw on the oil tank lock again.
Never use recycled oil or used oil. The guarantee expires
when using oil which is not allowed for chain saws.

Checking the 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.
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 channel (19).
If this is not successful please contact the customer
service.
Adjust the chain lubrication:
See also the instructions under "Maintenance /
cleaning: Adjusting the chain lubrication".
Fuelling
Utmost care is required when handling fuel
and oil. Do not smoke. Keep away open flames
(risk of explosion).
This product is operated by a mixture from regular
petrol (unleaded) and two-stroke engine oil.
Petrol: Octane number at least 91 ROZ unleaded
 Do not fill in leaded petrol, diesel or other non-approved
fuels.
 Do not use petrol having a smaller octance number than 91
ROZ. This may lead to severe engine damages due to
increased engine temperatures.
 If you frequently operate the product at high speeds, you
should use petrol with a higher octane number.
The use of unleaded petrol is recommended for envi-
ronment protection reasons.
Two-stroke engine oil:
acc. to JASO FC or ISO EGD specifications
 Do only use two-stroke engine oil for air-cooled engines.
