Mounting
Before you begin with the tree care, it is necessary to mount the saw
chain and the blade to the device. The chain (22) has very sharp edges.
When raising the chain (22) use safety gloves without fail.
1. First remove the chain guard from the blade unit.
2. Then rotate the locking screw on the cutting head (d) with the wrench (29)
counter-clockwise and remove the upper housing cover.
3. Set the saw chain into the groove guide of the blade unit (23). Start as
far as possible at the blade's top edge.
Pay close attention to the correct direction of the cut. On the blade unit
as well as in the inner housing below the chain wheel there is a direction
arrow, which must align with the direction of rotation on the blade.
Place the saw chain around the chain sprocket (e) and set the blade unit
on the bolt of the tension slide (f). Make sure that the bolt intervenes in
the corresponding opening on the blade.
If necessary, turn the screw on the tensioner (g). So that a uniform wear
of the chain blade is ensured, the the chain blade (23) should be rotated
e
after 8 - 10 working hours.
Make sure that there is always a correct tension of the chain and check
them before each use of the device. A loose chain could get loosened
from the guide groove of the blade unit and cause serious injury. Further a
loose chain also increases the danger of a backlash. In addition, the blade
, chain and chain sprocket get worn out faster
