Remove the additional cover needed when working with the trimmer head (Fig. (Rys.) 7b).
Lock the cutting attachment drive axis with a hex wrench (Fig. (Rys.) 7c).
Mount the three-armed knife on the shaft of the drive shaft (Fig. (Rys.) 7d).
Attach the spacer (Fig. (Rys.) 7e) and the washer from the pressed sheet metal (Fig. (Rys.) 7f).
Screw the cap (Fig. (Rys.) 7g) using the key provided in the set by turning counterclockwise (Fig. (Rys.) 7h).
SUSPENDERS
The suspenders' belt is put on the left shoulder and the hip cover will be on the operator's right, where the brushcutter's
suspension point is located. This cover protects the operator against vibrations of the working brushcutter, and also protects
the working clothes from contact with the brushcutter. An overview drawing of the suspenders Fig. (Rys.) 9.
REPLACING THE CUTTING LINE
Before replacing the line, check that the head is in good working order, is not worn, has no mechanical damage,
and is complete. If the head has any mechanical damage and excessive traces of use, the entire head must be replaced.
Stop the brushcutter's engine with the ignition switch 2 (Fig. (Rys.) 1).
Wait for all moving parts of the brushcutter to stop.
Empty the fuel tank.
Place the brushcutter on a firm, even surface with the head up.
Prepare a section of cutting line with a maximum diameter of 3 mm and a length of 4 meters.
Set the position of the arrow visible on the winding knob so that it coincides with the arrow on the head housing
(Fig. (Rys.) 11).
Enter the measured section of the line through the hole in the aluminum grommet, then gently maneuver insert the line so
that it comes out through the grommet on the opposite side of the head. Align the length of both ends of the line drawn
through the head.
Start winding the line by turning the winding knob clockwise.
Finish winding the line with the knob when about 15 cm of line protrudes on both sides of the head.
Attention! In the event that the line retracts inside the head, press both side latches at the same time as the head
narrows (Fig. (Rys.) 11).
Remove the top head cover, then slide both ends of the line into the grommets to guide the line out of the head. Pay special
attention to the proper seating of the vias in the head base. Incorrect assembly of the grommets in the base of the head will
cause them to fall out and, as a consequence, incorrect operation of the cutting line and excessive vibration transmitted by
the head.
Mount the bottom head cover by pushing the catches firmly into the mounting holes until you hear a characteristic "click".
Extend both ends of the cutting line about 15 cm. To do this, press the winding wheel and pull vigorously on both ends of the
line.
THE STARTING
Use Eurosuper 95 unleaded petrol and synthetic or semi-synthetic oil for high-speed two-stroke engines.
40: 1 mixture composition (4L fuel per 100 ml oil).
Table for the preparation of a 40: 1 fuel-oil mixture
The amount of gasoline in liters
The amount of oil in ml
Important! The use of synthetic oil for two-stroke engines will reduce the formation of spark plug, muffler and
cylinder pistons, as well as reduce exhaust emissions. It will also provide proper lubrication, which extends engine life. The
use of mineral oil (Mixol type) and its varieties as well as oils intended for four-stroke engines are strictly prohibited.
It is important to use only clean, fresh gasoline of good quality. The fuel mixture should be used within three weeks of its
preparation. First, prepare the fuel mixture and then fill the fuel tank. Do not mix in the fuel tank. To properly prepare the fuel
mixture, first pour gasoline into a special container (canister), then oil and mix. It is recommended to use the special
container included in the set, in which the amount of gasoline and the amount of oil to be added are marked. The whole
should be mixed thoroughly. (Fig. (Rys.) 14a-d)
