special working conditions, gloves and protective gog-
gles should be worn.
The tool has been designed and built to reduce noise to
a minimum (see technical data), however, in special
conditions the maximum noise level in the workplace
might exceed 85 dB(A). In this case, the operator should
protect himself from excessive noise by using ear pro-
tectors.
GENERAL SAFETY REGULATIONS
See manual "Safety instructions" which is supplied
together with this instructions manual.
INSTALLATION
1. ELECTRICAL CONNECTION
Before connecting the machine to the mains, one
must make sure that it complies with current regula-
tions in the country where it is used and that the
voltage and frequency are as indicated on the char-
acteristics plate.
When extensions are used, make sure that the cross
section of the cables is suited to their length. If using roll
up extensions, make sure that they unroll completely in
order to prevent overheating.
WARNING – before plugging in the machine, make
sure that the switch lock button is released.
2. WORKPLACE
The tool that you have purchased is a transportable or
semi-stationary electric tool. Only one operator is
needed to use it, given its structure, weight and ease of
handling.
In normal use, the operator is in front of the machine
with the handle to his right. The right hand on the handle
allows the machine to be handled completely, in fact, the
switch and a safety hook may be accessed without
releasing the handle.
CONSTANT ELECTRONICS
The built-in module permits:
- Soft start.
- The maintenance of a practically constant rated speed
up to rated power.
- An overload protection system by means of current
cut-off in the case of motor overload, in which case the
burring machine shuts down and re-starts when the
grinding pressure has been reduced.
MITRE SAW ADJUSTMENT - SQUARING
The mitre is delivered by the manufacturer already
adjusted and squared according to standard pa-
rameters.
WARNING – before making any adjustment of the
mitre, unplug the machine.
1. BLADE UNIT LIFTING
An internal spring keeps the motor unit at rest position
(raised).
In this position, a safety hook prevents the unit from
being activated accidentally.
1.1 To unlock the motor unit and to be able to use the
machine as a mitre saw, activate the front button D
(Fig.1) (the operation may be carried out with the
right hand on the handle).
1.2. To use the machine as a bench circular saw, un-
lock the motor unit as indicated in 1.1, and after lo-
wering it completely, block it with pin P (Fig.1a).
2. BLADE PENETRATION ADJUSTMENT
The depth of penetration has already been adjusted by
the manufacturer during testing.
As incorrect adjustment may cause sharpness to be lost
quickly and/or the teeth of the blade to be broken, further
adjustment might be needed, in which case it will be
necessary to work as follows:
- Activate bolt A (Fig.2) and the corresponding lock nut
to create a lower limit for the motor housing ideal for
preventing the blades from coming into contact with
the turntable.
WARNING – once for this operation is complete,
make sure that the blade is NOT in contact with the
turntable and that the lock nut is tightened.
3. TURNTABLE ADJUSTMENT
0º Regulation (Fig.3)
- Lower the head of the machine and lock with pin P
(Fig.1a).
- Set the turntable to zero.
- Loosen the handles V, remove the guides X – Optional
accessory and loosen bolts Y.
- Set a square between the saw blade and guide M
(Fig.1).
- Keeping the turntable at zero, move the guide to 90º
on the square.
- Tighten bolts Y, assemble guides X and adjust handles
V – Optional accessory.
4. ADJUSTING THE SAW BLADE WITH RESPECT TO
THE WORKING PLANE
90º adjustment (Fig.2)
- Lower the head of the machine and lock with pin P
(Fig.1a)
- Place a square between the base and the saw blade.
- Loosen lever O and adjust with bolt Z.
- Tighten the lock nut well to make sure that the position
is fixed and tighten lever O.
5. VERTICAL PLANE LIMIT STOP ADJUSTMENT (0º -
45º) (Fig.2)
- Lower the head of the machine and lock it with pin P
(Fig.1a).
- Set the turntable to zero and lock.
- Set the head to 45º and lean a 45º square between the
base and the saw blade.
- Loosen lever O and adjust using bolt Z.
- Regulate the 45º using bolt Z1 (Fig.1a), after releasing
the lock nut.
- Tighten the lock nut to make sure that the position
does not change.
OPERATION AND USE
1. CUTTING WITH THE BLADE AT 90º AND TURNTA-
BLE TURNED
- Unlock the turntable K (Fig.1) by turning lever N (Fig.3)
to the left.
- Turn the turntable with the handle, selecting the cutting
angle required using the graduated scale R2 and index
R (Fig.7), and lock again by turning lever N (Fig.3) to
the right.
Note: there are pre-set cutting angles (0º, ±15º, ±22º30',
±30º, ±45º) on which the turntable may easily be locked.
