• To lock the boom arm in the lower position you need to:
• Lock the boom arm in this position by inserting the head lock pin
(9).
VERTICAL CLAMPING
The vertical clamp (fig. B) can be mounted in the base of the saw
on either side of the work table and is fully adaptable to the size of
the material to be cut. Do not operate the saw unless the vertical
clamp has been used.
• Loosen the knob securing the vertical clamp (30) to the base on
the side where the vertical clamp will be mounted.
• Fit the vertical clamp by inserting it into the hole in the saw base
and tighten the vertical clamp fixing knob (30). to the base of the
saw.
• After adjusting the position of the vertical clamping arm (31) to
the workpiece, tighten the vertical clamping arm lock knob (32)
and the material clamping knob (33).
• Check that the material is securely mounted.
OPERATION / SETTINGS
Before carrying out any adjustment procedures on the saw, you
must ensure that it has been disconnected from the mains supply.
To ensure safe, accurate and efficient operation of your chainsaw,
all adjustment procedures must be carried out in full.
Ensure that all spanners are taken away after all adjustment and
setting operations have been completed. Check that all threaded
fasteners are properly tightened.
When making adjustments, check that all external components are
working properly and are in good condition. Any part that is worn
or damaged should be replaced by qualified personnel before
using the saw.
ON/OFF
The mains voltage must correspond to the voltage indicated on
the saw's rating plate.
The saw must only be switched on when the cutting disc is away
from the material to be machined.
The mitre saw has a switch lock button (3) to prevent accidental
start-up.
Switching on
Press the switch lock button (3).
Press and hold the on/off button (4).
Switching off
Release pressure on the switch button (4).
OPERATION OF TABLE EXTENSIONS
The table extensions (16) are located on both sides of the saw
base.
• Unlock the table extension lock knobs (18) (fig. C).
• Adjust the length of the table extensions.
• Fix with the table extension locking knobs (18).
• If required, pivoting end stops (17) can be used to facilitate
cutting to size.
OPERATION OF DEPTH OF CUT LIMITER
The cutting depth stop can be used when there is a need to make
a groove in the material. This is done by making a surface cut
into the workpiece when the disc is not operating at the full
possible depth.
• Lock the head lock lever (14).
• Loosen the guide lock knob (12) and move the head backwards.
• Tighten the guide lock knob (12).
• Turn the cutting depth stop (10) into the setting for operation with
limited cutting depth (fig. D).
• Lower the outrigger arm down and hold it in the down position,
resting it against the chisel depth stop.
• Turn (left or right) the cutting depth stop screw (11) (fig. D) until
the desired depth of the cutting disc is achieved.
• Loosen the guide lock knob (12).
• Make the planned cuts to the set depth.
• To return to full depth cutting, turn the cutting depth stop (10) to
a position where the cutting depth stop screw (11) does not
make contact with the cutting depth stop (10) when the boom
arm is lowered down.
SETTING OF THE WORK TABLE FOR ANGLED CUTTING
OPERATIONS
The swivelling boom arm allows the material to be cut at any angle from
perpendicular to 45° to the left or right.
• Pull back the head lock pin (9) allowing the boom arm to slowly
rise to the upper position.
• Loosen the work table lock knob (23).
• Press and hold down the auto-fixing lever (22) and rotate the
boom arm left or right until the desired angle value is indicated
on the angle scale of the work table (20).
• Lock by tightening the work table lock knob (23).
• The work table angle gauge (20) has a number of marked
positions in which the initial automatic fixing of the rotating boom
arm takes place. This can only take place if the auto-fixing lever
(22) is not held in the depressed position during rotation of the
boom arm and can lock into these pre-selected positions. These
are the most commonly used cutting angles (15°, 22.5°, 30°, 45°
left/right). The setting of any of these angles can be accurately
adjusted using the working table's angle graduation scale (20)
graduated in one degree increments. Although the scale is
sufficiently accurate for most jobs, it is recommended to check
the chisel angle setting with a protractor or other angle
measuring instrument.
CHECKING AND ADJUSTING
POSITIONING OF THE CUTTING DISC IN RELATION TO THE
WORK TABLE.
• Loosen the head lock lever (14).
• Set the head to 0° (perpendicular to the work table) and tighten
the head locking lever (14).
• Loosen the work table lock knob (23), press and hold down the
auto-fixing lever (22).
• Set the work table to 0°, release the automatic fixing lever and
tighten the work table lock knob (23).
• Lower the saw head to the extreme bottom position.
• Check (using a gauge) the perpendicularity of the positioning of
the cutting disc in relation to the work table.
When taking measurements, ensure that the measuring
instrument does not touch the tooth of the cutting disc as the
measurement may be inaccurate due to the thickness of the
carbide cap.
If the measured angle is not 90°, an adjustment is required, which is
carried out as follows:
• Loosen the lock nut and turn the 0° angle adjustment screw (42)
(fig. E) clockwise or counterclockwise to increase or
decrease the angle of the cutting disc.
• Once the cutting disc is perpendicular to the work table, allow
the head to return to the top position.
• Holding the 0° angle adjustment screw (42), tighten the lock nut.
• Lower the head down and check again that the set angle
corresponds to the indications on the head angle graduation
(34), if necessary adjust the position of the head angle indicator
(35) (Fig. E).
• A similar adjustment should be made for the 45° head angle for
bevel cutting using the 45° angle adjustment screw (43) (fig. E).
CHECKING AND ADJUSTING THE PERPENDICULARITY OF THE
CUTTING DISC IN RELATION TO THE STOP BAR.
This procedure must always be carried out when the stop bar
has been removed or replaced. This adjustment can only be
carried out once the cutting disc is perpendicular to the work
table. The stop bar serves as a stop for the material to be cut.
• Loosen the work table lock knob (23), depress and hold the
automatic fixing lever (22) and set the work table to 0°.
• Lower the saw head to the extreme bottom position.
• Apply a protractor or other angle measuring instrument to the
cutting disc.
• Slide the angle measuring device against the stop bar (15).
• The measurement should show 90°.
• If there is a need for adjustment:
• Loosen the screws securing the stop bar (15) to the base.
• Adjust the position of the stop bar (15) so that it is perpendicular
to the cutting disc.
• Tighten the screws securing the stop bar.
