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 o 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.
