JAMMING
If the blade jams as a result of attempting to cut
vegetation that is too dense, switch off the motor
immediately.
Remove the grass and scrub from the equipment
before you restart it.
PREVENTING RECOIL
When you work with the blade there is a risk of recoil
if it strikes solid objects such as tree trunks,
branches, tree stumps, stones or the like. This will
throw the equipment backwards in the direction
opposite to the rotation of the tool.
This can cause you to lose control of the equipment.
Do not use the metal blade near fences, metal posts,
boundary stones or foundations.
For cutting dense stalks, position it as shown in Fig. I5
to prevent recoil.
8. Maintenance
Always switch off the machine and pull out the spark
boot plug before carrying out any maintenance work.
8.1 Replacing the line spool / cutting line
1. Press the line spool housing together (Fig. L1)
below the two lugs (Fig. L2/Item 1) and remove
the line spool cover (Fig. L2/Item 2).
2. Take the line spool out of the line spool housing
(Fig. L3). Make sure that you do not lose the
spring or the washers.
3. Remove any remaining cutting line.
4. Place the new cutting line in the center and attach
the resulting loop to the recess in the spool
splitter (Fig. L4)
5. Wind the line on to the spool counter-clockwise
with tension. The spool splitter will separate the
two halves of the nylon line (Fig. L5)
6. Hook the last 15 cm of the two ends of the line to
the line holders opposite the line spool (Fig. L6)
7. Thread the two ends of the line through the metal
eyelets in the line spool housing (Fig. L3).
8. Press the line spool into the line spool housing.
Ensure that the spring and washers are in the
correct position (Fig. L3)
9. Press the line spool cover on to the line spool
housing. Ensure that the two lugs (Fig. L2/Item 1)
in the line spool housing lock into the appropriate
recesses (Fig. L2/Item 2) in the line spool cover.
10. Pull the two line ends briefly and powerfully to
release them from the line holders in the line
spool.
11. Cut the excess line to a length of around 13 cm.
This will reduce the load on the engine when

starting up and warming up.
12. Fit the line spool again. See point 5.4.
If you are replacing the complete line spool,
ignore points 3 – 6.
8.2 Maintenance of the air filter (Fig. J1-J3)
Soiled air filters reduce the engine output by supply
too little air to the carburetor.
Regular checks are therefore essential. The air filter
should be checked after every 25 hours of use and
cleaned if necessary. If the air contains a lot of dust,
the air filter should be checked more frequently.
1. Remove the air filter cover (Fig. J1-J2)
2. Remove the filter element (Fig. J3)
3. Clean the filter element by tapping it or blowing
it.
4. Assemble in reverse order.
Please note: Never clean the air filter with petrol or
inflammable solvents. Clean the air filter with
compressed air or by tapping it.
8.3 Maintenance of the spark plug (Fig. K1-K3)
Spark plug gap = 0.6 mm. Tighten the spark plug
with a torque of 12-15 Nm.
Check the spark plug for dirt and grime after 10
hours of operation and if necessary clean it with a
copper wire brush. Thereafter service the spark plug
after every 50 hours of operation.
1. Undo the screw to remove the spark plug cover
(Fig. K1)
2. Pull off the spark plug boot (Fig. K2) by twisting.
3. Remove the spark plug (Fig. K3) with the
supplied spark plug wrench.
4. Assemble in reverse order.
8.4 Grinding the safety hood blade
The safety hood blade (Fig. F6/Item A) can become
blunt over time. When you notice this, undo the two
screws holding the safety hood blade to the safety
hood. Clamp the blade in a vise. Sharpen the blade
with a flat file and make sure that the angle of the
cutting edge is not altered in the process. File in one
direction only.
8.5 Carburetor settings
Important. Settings on the carburetor may only be
made by authorized customer service personnel.
The air filter cover must be removed before any work
on the carburetor, as shown in Figures J1-J2.
Setting the throttle cable:
If the maximum speed of the machine falls over time
and you have ruled our all the other causes listed in
section 10 Troubleshooting, it may be necessary to
adjust the throttle cable.
First of all check whether the carburetor opens fully
