align it according to the mounting bores. Insert the 

three screws as shown in Fig. 4 and tighten them 

firmly.

ATTENTION: Make sure that all components 

are mounted and assembled correctly and all 

screws are properly tightened.
ATTENTION!

- Do always act in accordance with 

the applicable safety instructions and apply all 

required safety measures.  The trimmer may 

only be used to cut grass or smaller weeds. It 

is explicitly forbidden to cut any other kind of 

material. Do not use the trimmer as a lever to 

lift, remove or crush objects; do also not fix it 

to rigid holding devices. It is forbidden to mount 

any devices or supplements to the trimmer’s 

drive unit that are not explicitly released for that 

purpose by the manufacturer.

3. ASSEMBLY OF THE  PROTECTION COVER 

(Fig. 5)

Mount the protection shield extension as shown in Fig. 5 

using the 3 included screws nuts and washers. 

ATTENTION: When operating the device in 

connection with the nylon line cutting head, 

the plastic protection cover must always be 

installed to cut the nylon cutting line to the cor-

rect length and to protect the operator. 

4. ASSEMBLY OF THE NYLON LINE CUTTING HEAD

1.  Remove the split pin from the end of the drive shaft 

(Fig. 7). 

2.  Insert an Allen key into the hole on the side of the low-

er retaining flange to prevent the gear from turning. 

Use the included wrench to unscrew the nut turning it 

clockwise (Fig. 8). 

3.   Remove the upper retaining flange.

  Make sure to keep the nut, split pin and upper 

retaining  flange.  These  parts  will  be  required  to 

mount the metal blade!

4.  Screw the cutting head onto the thread by turning it 

anticlockwise and fasten it hand-tight (Fig. 6).

  Please make sure that the line spool is properly seat-

ed in the spool housing, the spring is located under 

the line spool, and the line ends are led to the outside 

through both eyelets.

5. ASSEMBLY OF THE METAL CUTTING BLADE

ATTENTION! - Do not use the device if the cut-

ting blade is deformed or the cutting teeth are 

defective or even lost. Replace defective cutting 

blades immediately!
ATTENTION! - Never operate devices with cut-

ting blade without a properly installed metal 

cutting blade protector. Do not operate the 

device with a defective blade protector.
ATTENTION! - Always wear rugged protection 

gloves when working on the cutting blade. 

1.  Remove the split pin from the end of the drive shaft 

(Fig. 7). 

2.  Insert an Allen key into the hole on the side of the low-

er retaining flange to prevent the gear from turning. 

Use the included wrench to unscrew the nut turning it 

clockwise. 

3.  Remove the upper retaining flange. 

4.  Mount the blade as shown in Fig. 9. Put the flange 

with its flat surface onto the cutting blade (Fig. 9).

5.  Use the included wrench to tighten the nut turning it 

anticlockwise. 

6.  Secure the screw with the split pin again (Fig. 10).

7.   Make sure to unblock the gear again by removing the 

Allen key from the bore on the side of the retaining 

flange.

8.  To exchange the line cutting head with the metal 

blade please proceed as follows: 

  Insert an Allen key into the hole on the side of the 

lower retaining flange to prevent the gear from turning 

(Fig. 5). Manually unscrew the line cutting head clock-

wise. Proceed as described in points 4-6. 

6. ASSEMBLY OF THE SHAFT COUPLING 

(fig. 11+12)

Put the lower shaft (2) into the shaft coupling and concur-

rently pull out the locking pin (1). Slide the lower shaft in 

as far as it will go and let go of the locking pin. The locking 

pin must engage into the opening (3) located laterally in 

the lower shaft. Of necessary, slightly move the lower shaft 

to-and-fro until the locking pin safely locks in place. Then 

tighten the fly nut (4).

7. 

ASSEMBLY OF THE SHOULDER STRAP

ATTENTION! - Always use the shoulder strap. 

Attach the strap to the device immediately after 

starting it whole the engine is idling. Always 

switch  the  engine  off  first,  when  you  detach 

the strap.

1.  Put the strap on; the strap must lead over your right 

shoulder (Fig. 13).

2.  Hook the snap hook of the shoulder strap into the 

bracket provided at the main tube (Fig. 14). 

3.  Adjust the length of the strap such that the cutting 

tool is positioned parallel to the ground, when the 

strap is put over the shoulder. Determine the correct 

adjustment for the respectively installed cutting tool 

by performing some test swings with the engine 

switched off.

4.  Never carry the belt diagonally across your shoulders 

and chest, but rather only on one shoulder, so that 

you can rapidly move away from the tool in case of 

danger.

NOTE: 

Never start the engine with the shoulder strap 

hang up.
