13. CUTTING TIPS

1. Before commencing cutting operations, read the safety instructions given in the previous

sections.

2. At first the setting of a relatively high cutting height is recommended (using the relative

lever in figure 2, ref. A), lowering it gradually according to working conditions.

3. Engage the blade clutch (Fig. 1, ref. A) only after having carried out the machine

switch-on and gear engagement operations.

4. Before engaging the blade clutch (Fig. 1, ref. A), gradually move the accelerator (Fig.

1, ref. B) until the required speed is reached.

WARNING

Take great care because the blade moves at very high speed.

14. CHECKS

- Adjust the belt and cable control tension after the first few working hours to compensate

initial loosening.

- Briefly operate all the machine’s components to detect any abnormal noises or

overheating.

- During the initial running in period avoid heavy-duty usage to encourage proper settling

of the mechanical parts.

- Never neglect maintenance operations after work and carry out all prescribed checks

regularly.

A) TYRE PRESSURE

Regularly check the tyre pressure. If both two tyres are not inflated to average pressure

the machine will tend to travel sideways during operation.

B) CABLE CONTROL ADJUSTMENT

To adjust the cables place the machine on flat ground, switch off the engine and disconnect

the wire from the spark plug.

B1)BLADE CONTROL CABLE

Make sure that there is no play between the upper end of the cable and the adjustment

screw. If there is, or if the cable has stretched, restore to ideal position using the relative

adjustment screw(Fig. 5, ref. A).

If adjustment using the relative screw proves ineffective, the belts, and hence the engine

mounting, must be adjusted. To perform this operation refer to section 14C “ BELT

REPLACEMENT AND ADJUSTMENT” of this manual.
