Before you can start with the tree care, it is necessary to mount
the saw chain and the blade to the device. The chain (29) is very
sharp-edged. Be sure to wear safety gloves when mounting the
chain (29).
1. First, remove the chain guard from the blade unit.
2. Then turn the locking screw on the cutting head (d)
counterclockwise with the wrench (24) and remove the upper
housing cover.
3. Insert the saw chain into the groove guide of the blade unit
(30). Start at the top of the blade if possible.
Be sure to pay attention to the correct cutting direction. There
are direction arrows, which must coincide with the running
direction on the blade on the blade unit and in the inner housing
below the sprocket.
Now place the saw chain around the sprocket (e) and place the
blade unit on the pin of the cocking slide (f). Make sure that the
bolt engages in the corresponding opening on the blade.
If necessary, turn the tensioner screw (g).
To ensure the even wear of the chain blade, the chain blade (30)
should be turned after 8 - 10 working hours.
Always pay attention to the correct chain tension and check it
before every use of the device.
A loose chain could come off the groove guide of the blade
unit and cause serious injury. Furthermore, a loose chain also
increases the risk of blowback.
In addition, blade, chain and sprocket wear out faster.
