1. Place the chain saw on any suitable flat surface.
2. (See Fig. 4a) Slide the chain (8) in the slot around the guide bar (7). Ensure chain is in
correct running direction by comparing with chain symbol (15). Ensure the chain tensioning
catch (16) is facing outwards.
3. (See Fig. 4b) Fit the chain onto the drive sprocket (13) and guide the guide bar (7), so that
the fastening bolt (18) and the two guide fins (14) fit into the keyway of the guide bar (7).

WARNING: ALWAYS

increase the risk of kickback. A loose chain may jump out of guide bar groove.
This may injure operator and damage chain. A loose chain will cause chain, chain
bar, and sprocket to wear rapidly. The chain life of the saw chain mainly depends
upon sufficient lubrication and correct tensioning. Avoid tensioning the chain if it
is hot, as this will cause the chain to become over tensioned when it cools down.
1. Place the chain saw on any suitable flat surface.

2. Turn the locking knob/ chain tensioning knob
clockwise until the locking knob is screwed tightly,
(See Fig. 4d). The correct chain tension will be
reached automatically. The ratchet mechanism

prevents the chain tension from loosening.
3. The correct chain tension is reached when the chain
can be raised approx. 3-6 mm (1/8 to 1/4-in.) from
the chain bar in the centre. This should be done by
using one hand to raise the chain against the
weight of the machine. (See Fig. 5)
4. When the chain loosens, unscrew the locking
knob/chain tensioning knob absolutely and then
Screw on the cover plate with the locking knob
tightly again.
