MOUNTING THE HANDLE (OF THE STEERING WHEEL)
Before mounting the steering wheel on the shaft pipe connect the handlebar with the handle with throttle lever. To do that release the
screw on the handle (Fig. (Rys.) 4b) and eject the connector (Fig. (Rys. 4c). Next insert the handlebar into the connector (Fig. (Rys.) 4d)
and push the connector back inside of the handle (Fig. (Rys.) 4e). Tighten the screw to secure the connector (Fig. (Rys.) 4f).
Unscrew the handle mounting screws 13 (Fig. (Rys.) 1) as in Fig. (Rys.) 4g and remove the handle cover (Fig. (Rys.) 4h).
Place the handle in the collet, which is already attached to the shaft pipe (Fig. (Rys.) 4i) . Lay the collet cover on it and screw both parts of
the cover together with the steering tube as in Fig. (Rys.) 4j.
ASSEMBLY OF THE CUTTING ATTACHMENT COVER (ASSEMBLY OF THE SAFETY COVER)
Mount the line cutting knife (Fig. (Rys.) 5b) onto the safety cover. Unscrew the band fastening the safety cover
2 (Fig. (Rys.) 3). Attach the cover as in Fig. (Rys.) 5c, put on the retaining band, which should be tightened with the
hexagon bolts (Fig. (Rys.) 5c, d).
Attention! Using the brushcutter without an effective safety guard endangers the safety of the brushcutter operator and
bystanders.
CONNECTING DRIVE SHAFT
Remove the covers securing the ends of the shaft tubes (Fig. (Rys.) 8b). Connect the two pipes in which the drive shaft is
located (Fig. (Rys.) 8a) until the locking pin engages (Fig. (Rys.) 8c, d). Tighten the butterfly visible on Fig. (Rys.) 8e.
ASSEMBLY OF THE CUTTING ATTACHMENT
ASSEMBLY OF SPOOL WITH A LINE
Lock the cutting attachment drive axis with a hex wrench (Fig. (Rys.) 6b).
Unscrew the cap (Fig. (Rys.) 6b) the nut is unscrewed clockwise.
Remove the washer from the pressed sheet metal (Fig. (Rys.) 6c), remove the spacer (Fig. (Rys.) 6d).
Now we proceed to assembly the head with a cutting line (Fig. (Rys.) 6e).
Screw the cutting head with the cutting line by turning it counterclockwise (Fig. (Rys.) 6f) remembering to block the drive
shaft with the hex key.
ASSEMBLY OF THE THREE-ARM KNIFE
Unscrew the cap (Fig. (Rys.) 6b) the nut is unscrewed clockwise.
Remove the washer from the pressed sheet metal (Fig. (Rys.) 6c), remove the spacer (Fig. (Rys.) 6d).
We proceed to mount the three-armed knife.
Remove the additional cover needed when working with the trimmer head (Fig. (Rys.) 7b).
