Make sure that the cutting accessory has been securely
fastened in all its parts as described above and posi-
tioned in such way that the rotation direction indication
arrow and the safety messages (Fig. 18) are clearly
legible from above.
The disk can CAUSE SERIOUS DAMAGE AND
INJURY if not correctly positioned and locked
in place.
The fixed cup (or the adjustable support cup
OPTIONAL) when positioned on the ground keeps the
cutting accessory raised during operation and permits
cutting to be performed at a uniform height as long as
the rod is maintained at a constant inclination. It also
prevents the cutting accessory from coming into contact
with the ground or small protruding stones.
Disk saws for deforestation:
Use only disk saws that conform to CE standards after
previously mounting the appropriate CE trunk retainer
guard. These articles are supplied as OPTIONALS.
- Fastening: follow the instructions provided for the
fastening of steel disks.
- Safety guard: always mount the appropriate CE trunk
retainer guard.
Both the disk saw and the CE trunk retainer guard
are provided as OPTIONALS.
Never use knives, blades or cutting elements other
than those provided by the manufacturer, and always
use only tools in perfect condition free of dents,
cracks, deformation, or broken or worn-out teeth
that may cause the breakage of the cutting element.
Given the high rotation speed, broken pieces can fly
off at tremendous speeds for serious risks of dam-
age and injury for which the manufacturer declines
all responsibility.

4.1 Introduction

The machine is provided with a set of "safety
guards" for your protection; make sure that they
are all in place and in good working order before
starting the machine.

4.2 Fuel

- The brushcutters have been designed for operation
with both premium grade fuel and lead-free petrol.When
using lead-free petrol, we recommend using synthetic oil
specifically formulated for two-stroke engines subjected
to high stress to be mixed in the percentage indicated
on the packaging (usually 2%).
Whenever mineral or semi-synthetic oils are used, the
percentage of oil must be 5%.
The use of synthetic oil specifically formulated for two-
stroke engines reduces the formation of fuel ash and
deposits both on the spark plug and piston and in the
cylinder and muffler, and the emission of exhaust as
well.
