4. Operating instructions

4.1 Placement and testing

STARTING
Hold the cutter firmly with both hands at the grips.
1. Push button "M" to start.
2. For continuing work, lock button "M" by pushing button
"T".
3. To stop and unlock the machine, push "M".
4. Wait for the machine achieving full speed before any
works.
5. To stop, simply release button "M" (fig. 5).
CARBON BRUSH REPLACEMENT (PR12E) (fig. 17)
- Replace carbon brushes "J" when the machine does
not work, works irregularly or after many sparks.
- Carbon brushes "J" with less than 5 mm must be
replaced.
- Do always replace both carbon brushes at the same
time.
- Rotate covers "E" using a screw driver (black-
coloredcovers which can be found beside the tool).
- Take out the worn-out carbon brushes "J" and clean
the compartments using compressed air.
- Position the new carbon brushes in the reverse order.
- Put covers "E" by turning smoothly.
- After having placed the new brushes "J", let the tool run
for some minutes to allow the brushes to adjust.

4.2.Tuning operations

VARIABLE SPEED (fig. 6)
Located at the right upper portion of the machine (PR12E)
or handle (PR10E) there is the variable speed button "B".
To increase or reduce the speed "B", it is only necessary
to rotate the knob. The smaller the cutter is, the higher
is the speed and viceversa. Acutter rotating to fast or
advancing to slowly may burn the work piece entailing the
hazard of fire.
DEPTH ADJUSTMENT (fig. 7)
This machine is equipped with a depth stop "H" and a
depth scale "G" allowing a quick selection of the depth.
The magnifier at the register line can also be slid upwards
or downwards to facilitate adjustment and lecture of the
depth scale.
The depth stop "H" and the scale "G" can be moved
upwards and downwards by rotating "L" the knurled
adjustment screw "K" clockwise or counterclockwise to
set the position of the cutter regarding the work piece or
the required cutting depth, relative to the depth scale "G"
by using the locking button "K" to lock the distance.
FINE ADJUSTMENT (fig. 7-8).
When the approximate depth has been set and locked,
a finer adjustment may be carried out by using micro
adjustment knob "D". An additional adjustment (depth of
penetration) may be achieved by means of the knurled
screw at the bottom of the depth scale, stop "H".

4.3 General instructions for use
In accordance with the different applications, there is a
great variety of milling cutters of very different realizations
and qualities.
High yield quick cutting steel milling cutters are suitable
to work on soft materials as for example soft wood and
plastic.
Milling cutters with hard metal blades are especially
suitable to work on hard and abrasive materials as for
example hard wood and aluminum.
WARNING: Do use clean milling cutters and in a perfect
condition.
CUTTING IN MULTIPLE RUNS
This machine is equipped with a turret "I" mechanism
establishing the maximum cutting depth by means of
seven stages. Each step of the turret is approximately to 3
mm cutting depth. Adjust the desired depth with the turret
depth scale starting from its minimum stop.(fig.10).
This depth is set in a maximum of seven steps. Rotate the
turret "I" so that the highest configuration is aligned with the
depth "H" stop screw and complete the first step. Rotate
the turret "I" to beside the most suitable cutting depth and
complete the following step. Repeat this procedure until
the required depth has been achieved.
USING THE PARALLEL GUIDE
Parallel guide "A" may be used to make a cut at a distance
that is parallel to the edge of the work piece.
Slide the parallel guide "A" to the desired cutting distance.
By positioning the guide bars at the bottom of the cutter,
and secure with the fixing knob "R".
To carry out the operation, firmly hold the stop of the
parallel guide "A" at the edge of the work piece.
USING THE HOLE-CUTTING ATTACHMENT (only PR12E)
To use the hole-center cutting accessory, first remove the
guide mechanism and only one of the rods which support it.
Place center-cutting accessory "P" on the rod which remains
installed at the machine (figs. 11-12). Carry out the circular
cut taking into account the radius of the (fig. 11).
USE OF THE GUIDE PLATFORM (fig.2-13)
The guide platform "O" is used for making a pre-cut or a
cut using a template; place the template "O" with its central
bushing protruding from its bottom. Latch the template by
pulling locker "U".
The guide platform is ready to continue to reproduce the
profile silhouette template.
1. Place the machine backwards as indicated in fig.13,
remove the screws.
2. Insert platform at the base of the machine and secure
the screws.
