Attention: Under full load there are at least 1 l of water per minute required. For cooling
and cleaning the bar / chain during the operation of the chain saw, we recommend a larger
water flow - see section 3.1 Technical data. Open the ball valve after use, so that the
cooling gap can empty. This is mainly required in the cold season - danger of frost.
4.4 Mounting / Replacing the Drive Wheel, bar and Diamond Chain
Open the eccentric lever [11] in the horizontal position and screw it back until the cover [14] of the chain
housing [4] can be removed.
Drive sprocket
Remove the factory mounted
locking ring [16] using a locking
ring pliers (not part of the scope
of delivery) and the washer [17].
Slide the drive sprocket [18]
onto the output spindle [19] of
the chain saw.
Mount the washer and the
locking ring. Check that the
locking ring is correctly seated
in the groove of the output
spindle.
Bar and diamond chain
Place the diamond chain into
the guide groove of the bar.
Guide the chain around the
drive sprocket.
Position the bar with the chain in a way that the long hole in the bar is aligned to the key [20] in the chain
housing. Align the adjustment pin [21] of the chain tension screw [8] on the hole in the blade.
Clamp the chain easily by turning the chain tensioning screw clockwise (viewing direction: chain
tensioning screw).
Check that the drive links of the chain fit the drive sprocket and are located in the guide groove of the bar.
Place the cover on the chain housing and push it backwards until the contour of the cover coincides with
the contour of the chain housing.
Screw the screw of the eccentric lever into the knurled nut [15] so that the cover and the sword are fixed
- do not close the eccentric lever yet.
Tension the diamond chain by turning the tensioning screw clockwise by hand and simultaneously lifting
and lowering the top of the bar. Alternatively, the clamping screw can also be turned by means of a
screwdriver or a wrench. If the chain is tensioned too much, a high proportion of the motor power is
applied to the movement of the chain - in extreme cases, the saw motor can not rotate the chain.
See figure for correct tensioning of the diamond chain:
