Tensioning the Saw Chain (see figure A)

Always check the chain tension before use, after

the first cuts and regularly during use approx.

every 10 minutes. Upon initial operation, new

chains can lengthen considerably.

The chain life of the saw chain mainly depends

upon sufficient lubrication and correct tension-

ing.

Avoid tensioning the chain if it is hot, as this will

cause the chain to become overtensioned and

face too tightly against the chain bar when it

cools down.

– Place the chain saw on any suitable flat sur-

face.

– Turn locking knob 15 approx. 1 – 3 turns anti-

clockwise to loosen the chain bar.

– Check if the chain links are correctly located

in the slot around the chain bar 12 and on the

drive sprocket 18.

– Turn the red chain-tensioning ring 14 clock-

wise ratcheting until the correct chain ten-

sion is reached. The ratchet mechanism pre-

vents the chain tension from loosening. If the

chain-tensioning ring 14 is hard to turn, loos-

en the locking knob 15 further in anticlock-

wise direction. The locking knob 15 may also

turn, when adjusting the chain-tensioning

ring 14.

– The saw chain 11 is correctly tensioned when

it can be raised approx. 3 – 4 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.

– If the saw chain 11 is overtensioned, turn the

chain-tensioning ring 14 in anticlockwise di-

rection.

Clamping the Chain Bar

– When the chain 11 is tensioned, clamp the

chain bar 12 by turning the locking knob 15

in clockwise direction. Do not use a tool for

this.

Saw-chain Lubrication

(see figures A–B)

Note: The chain saw is not supplied filled with

oil. It is essential to fill with oil before use. Op-

erating the chain saw without chain oil or when

the oil level is below the minimum mark will re-

sult in damage to the chain saw.

Chain life and cutting capacity depend on opti-

mum lubrication. Therefore, the chain is auto-

matically lubricated with chain oil during opera-

tion via the oil outlet 19.

Filling the oil reservoir:

– Set chain saw on any suitable surface with

the oil filler cap 4 facing upward.

– Clean area around the oil filler cap 4 with a

cloth and unscrew the cap.

– Do not remove filter insert during filling.

– Add Bosch biodegradable chain saw oil until

reservoir is full.

– Avoid dirt or debris from entering the oil res-

ervoir. Screw on oil filler cap 4 again and

tighten.

Note: Important: To allow venting of the oil res-

ervoir, small breather channels are provided be-

tween the oil filler cap and the strainer. To pre-

vent leakage ensure chain saw is left in a

horizontal position (oil filler cap 4 uppermost)

when not in use.

Note: It is important to use only the recom-

mended biodegradable oil to avoid damage to

the chain saw. Never use recycled/old oil. Use of

non approved oil will invalidate the warranty.
