Harness
CAUTION! It is very important to famil-
iarize yourself with the release mecha-
nism. In case of emergency you need to be
able to release the machine quickly.
The harness is equipped with a fasten-release
mechanism. The harness enables the operator to
support the machine during use (see “Safety pre-
cautions”, B7).

Preparation of the mixture
Do not use any other type of fuel than the
type recommended in this manual. This
machine is equipped with a two-stroke engine
and should therefore be fueled with a mixture of
unleaded gasoline (with a minimum octane rating
= 90) and fully synthetic oil specific for two-speed
engines that use unleaded gasoline in the propor-
tions indicated in the table on the cover, fig. D.
Control the specifications of the oil shown
on the package; the use of oil lacking the
specifications expressly indicated in this manual
could cause serious damage to the engine!
To obtain the best mixture, pour the oil into an
approved container first, followed by the gasoline,
and shake the container well (every time you take
fuel out of it).
The characteristics of the mixture tend to deteriorate
in time, so you should only prepare as much mixture
as you are going to need (the use of deteriorated
fuel can seriously damage the engine).
Filling the tank
Clean the area around the fuel cap before remov-
ing it, to prevent any impurities from contaminat-
ing the fuel. Take the cap off the fuel container
carefully. Unscrew the cap on the fuel tank and fill
it with the necessary quality, using a funnel.
During use, to prevent problems in starting the
engine again, we strongly recommend that you
avoid letting the fuel run out in the tank.
Fuel storage
Store the fuel in a cool, well-ventilated
place, in an approved fuel storage container.
Never store the engine with fuel in the tank in a
poorly ventilated place where the fumes produced
by the gasoline could propagate and reach a fire,
candle, burner or furnace pilot light, water heater,
dryer, etc. Never store excessive quantities of
fuel.

E. Assembly/disassembly
E1. Delta grip
For your safety, fasten the delta handle in front of
the label placed on the shaft at a distance of at
least 18 cm from the rear grip. The handle should
be fastened in a comfortable working position.
The safety pole guard should be mounted using
the accessories supplied and in the configura-
tion shown in the figure,in contact with the delta
handle.
E2. Double Handle
Adjust and secure double hand clamp by tighten-
ing the screws.
E3. Assembly of safety guard
Fit the safety guard (A) against the gearbox (I)
position the lower clamp (G) in the housing under
the shield and the upper clamp (F) over the shaft.
Insert and tighten the screws (H).
Safety guard extension (exclusively for use
with nylon string head)
• The extension (B) should be installed only for
use with the nylon string head, with the aid of
the string cutter blade (L), that regulates the
length of the string and thus the cutting diame-
ter.
• For correct assembly see the illustration on the
cover and perform the following sequence of
steps:
• Insert the extension (B) on the safety guard (A)
at the reference notches (C), and fasten with
the screws (D), then apply the string cutter
blade (L) with the cutting edge facing towards
the outside of the shield, and fasten it with the
screw (E) (Make sure the screws are tightened
all the way (E) and are not loosened by the
vibrations. If necessary, tighten them again).
CAUTION! If you are using the grass cut-
ting blade, remove the extension (B) on the
guard (A).
