SETTING OF THE BOOM ARM (HEAD) FOR MITRE CUTTING
OPERATIONS
The boom arm can be inclined at any angle between 0° and 45° -
for bevel cutting (Fig. E).
• Pull back the head lock pin (9) releasing the outrigger arm and
allowing the outrigger arm to slowly rise to the top position.
• Loosen the head lock lever (14).
• Tilt the boom arm to the left at the desired angle, which can be
read on the head angle scale (34) using the head angle indicator
(35) (fig. E).
• Tighten the head lock lever (14).
If it is necessary to adjust both angles (in both planes,
horizontal and vertical), for combined cutting, the bevel cutting
angle must always be adjusted first.
CHECKING THE OPERATION OF THE LASER
The laser unit assembly sends out a beam of laser light showing
the line on the material along which the cutting blade will cut. The
appropriate setting of the laser beam incidence line has been
adjusted during the manufacturing process. However, for precision
work, the setting should be checked before starting the cutting
operation.
• Place the batteries in the battery tray (36) (Fig. F) making sure
that the correct polarity is observed.
• Place the work table in a position for which the work table angle
indicator (21) coincides with the 0° point on the work table angle
scale (20) and the head angle indicator (35) (fig. E) coincides
with the 0° point on the head angle scale (34) (fig. E).
• Fix a suitable piece of waste material on the work table (25) and
make the cut.
• Release the boom arm and leave the waste material secured on
the saw work table.
• Set the laser switch button (37) to the on position "I" (marked).
• The projected light beam should be parallel to the cut.
LASER ADJUSTMENT
When adjusting the laser guide beam, do not look directly at the
beam or its reflection on the mirrored surface. The laser unit must
be switched off when the laser is not in use.
If the laser beam is not parallel to the cut, it is necessary:
• Gently turn the laser (38) (Fig. G) in the laser module housing
(26) to the left or right until the laser beam is parallel. Do not
rotate the laser module by force and more than a few degrees.
• If lateral adjustment is required, loosen the laser module fixing
screws (39) and move the laser module to the left or right until
the laser line is parallel to the cut.
Dust from cutting can dull the laser light, so the laser projector
lens needs to be cleaned from time to time.
STARTING THE SAW
Before pressing the switch button, make sure that the saw has
been properly assembled and adjusted as indicated in this manual.
The saw described has been designed for right-handed users.
• Press the switch lock button (3).
• Press the on/off button (4).
• Allow the chainsaw engine to reach full speed.
• Lower the boom arm towards the workpiece.
• Make the cut.
STOPPING THE CHAINSAW
• Release pressure on the switch button (4) and wait until the disc
stops rotating completely.
• Raise the boom arm of the saw, moving it away from the material
to be cut.
Temporary sparking of the brushes inside the electric motor is
normal when starting and stopping the saw. Do not stop the saw
blade by exerting lateral pressure on it.
SAW CUTTING
Clamp the material to be cut so that it does not interfere with use
of the saw. Before starting the saw, move the saw head to the
bottom position to ensure that the saw head and saw blade guard
have full freedom of movement. Ensure that the saw blade guard
is in its extreme position of travel.
Ensure that the work table lock knob (23) and head lock lever (14) of the
saw are securely tightened before cutting.
• Connect the saw to the mains.
• Ensure that the power cord is away from the cutting disc and the
base of the machine.
• Place the material on the work table and ensure that it is
securely fixed so that it cannot move during cutting.
• Move the saw head to the extreme rear position and lock the
guide bar (13) with the guide bar lock knob (12).
• Unlock the cutting head and the cutting disc guard.
• Press the switch lock button and start the saw with the switch
(wait until the saw blade has reached its maximum speed).
• Slowly lower the saw head.
• Start cutting by exerting moderate force on the head while
cutting.
Failure to tighten the locking knobs can cause the cutting disc to
move unexpectedly against the upper surface of the material,
putting the operator at risk of being dangerously struck by a
piece of material.
SAWING WITH TRAVERSE OF THE BOOM ARM (HEAD)
The movement of the saw's extension arm allows the cutting blade to
move forwards and backwards allowing wider pieces of material to be cut.
• Move the boom arm to the upper position.
• Loosen the guide lock knob (12).
• Before switching on the saw, pull the boom arm towards you,
holding it in the upper position.
• Press the switch lock button (3) and start the saw.
• Release the boom arm and wait for the cutting disc to reach its
maximum speed.
• Release the cutting disc guard.
• Lower the boom arm and start cutting.
• Move the boom arm backwards (away from you) while cutting.
• Once the material has been cut, release pressure on the switch
button and wait until the cutting disc stops rotating before raising
the boom arm to the upper position.
Never make a cut by moving the saw head towards yourself. The
saw blade could unexpectedly climb onto the material to be cut,
putting the operator at risk of a dangerous kickback
phenomenon.
OPERATION AND MAINTENANCE
Unplug the power cord from the mains socket before carrying
out any installation, adjustment, repair or operation.
CLEANING
• When finished, carefully remove all pieces of material, shavings
and dust from the work table insert and the area around the
cutting disc and its guard.
• Ensure that the ventilation slots of the motor housing are
unobstructed and free of chips or dust.
• Clean the guides and coat them with a thin layer of solid
lubricant.
• Keep all handles and knobs clean.
• Clean the lens of the laser projector with a brush.
REPLACEMENT OF THE CUTTING DISC
• Lift the cutting disc guard (7) and remove the centre plate fixing
screw (40) (fig. H).
• Slide the central plate (41) to the left to allow access to the cut-
off wheel fixing screw.
• Press the spindle lock button (6) and rotate the cutting disc until
it locks.
• Using the special spanner (supplied), loosen and remove the
bolt holding the cutting disc.
• Remove the outer washer and remove the cutting disc (paying
attention to the reduction ring if present).
• Remove any debris from the spindle and cutting disc mounting
pads.
• Install the new cutting disc by following the steps described in
reverse order.
• When finished, ensure that all spanners and adjustment tools
have been removed and that all screws, knobs and bolts are
securely tightened.
