ASSEMBLY

3.1 Assembly
Make sure that all parts have been assembled correctly
before starting to work.

3.1.1 Models with rigid shaft

Rod-engine: (Fig. 4). After orienting the rod, connect it
to the engine by inserting it in the hole in the clutch case.
In order to make sure that the rod has been inserted
correctly, check that the red line on the label lines up
with the profile of the rod retainer jaws.
At this point, lock the rod in place in such way that it
cannot be removed from the engine and screw down
the two screws in the jaws.
Handle-bar: (Fig. 5). Proceed as follows to lock the
handle-bar securely to the rod: insert the two drilled
plate half-bearings A between the handle-bar support C
and the handle-bar pipe B, then take the handle-bar B
and position it so that it can be gripped with the control
handle with the accelerator cable in your right hand and
the simple grip D in your left hand. After positioning the
handle-bar B on the cross C, lock it in place with the
cross cover and the four respective fixing screws.
Before fixing the handle-bar in place, make sure it is
fastened so that your arms and wrists are flexed slightly
in normal work position. If you work in such way that
only your wrists are flexed and your arms are straight,
the force required may be excessive, especially on your
right hand, which is under constant strain by the need
to continuously work the accelerator trigger.
Vibration-damping grip: (Fig. 6). Position the vibration-
damping grip E in the cross F by keeping the longer
part facing left (this serves as a protective barrier during
operation that prevents involuntary contact of your body
with the cutting accessory). Before definitively tightening
the fixing screws, adjust it in a position that permits the
ergonomic use of the machine.
Then definitively screw down the fixing screws.
Connection of the gas control acceleration cable for
models with rigid shaft: (Fig. 7). There is a gas control
cable that leaves the accelerator handle. This cable has
a threaded terminal at its end, and there are two nuts
screwed into the terminal. Take the gas control cable
and insert one end into the swivel for the control of the
carburetor butterfly valve. Then position the threaded
terminal into the respective housing in the nylon cylinder
cover, making sure to pass the steel cable beneath the
respective track. Then fasten the threaded terminal to
the cylinder cover by working on the nuts. Then adjust
the threaded terminal in order to eliminate all slack be-
tween the cable and the sheath in order to ensure correct
and progressive acceleration. This threaded terminal
has been built to CE standards and serves to prevent
undesired acceleration of the machine if the control is
ever accidentally contacted. Then connect the ground
cable's eyelet terminal to one of the four fixing screws
on the cylinder cover that supports the clutch case and
connect the ground cable's female faston to the male
faston coming from the coil. In models equipped with
handle-bars, pass the gas control cable unit inside the
respective lateral housings in the cross, and the two
cable guides positioned on the rod in order to make
sure that the gas control unit is fitted as closely to the
machine as possible.
