• Raise the blade until it is about 3 mm higher than the top of the
workpiece. Adjust the height of the upper blade guard as necessary.
• Adjust the position of the L-shaped fence profi le (16) level with the
back of the riving knife. When ripping wide pieces of material, slide
the L-shaped fence profi le (16) off the main part of the fence, rotate
vertically through 180° and replace to provide additional support.
• Hold the workpiece fl at on the table and against the fence. Keep the
workpiece away from the blade.
• Keep both hands away from the path of the blade (fi g. M2).
• Switch the machine on and allow the blade to reach full speed.
• Slowly feed the workpiece underneath the guard, keeping it fi rmly
pressed against the rip fence. Allow the teeth to cut, and do not force
the workpiece through the blade. The blade speed should be kept
constant.
• Always use a push stick (15) when working close to the blade (fi g. M1).
• After completing the cut, switch the machine off, allow the blade to
stop and remove the workpiece.
WARNING:
• Never push or hold the "free" or cut-off-side of the workpiece.
• Do not cut excessively small workpieces.
• Always use a push stick when ripping small workpieces.
Bevel cuts
• Set the required bevel angle
(refer to the section "Adjusting the rip scale").
• Proceed as for ripping.
Cross-cutting and bevel crosscutting
• Remove the rip fence and install the mitre gauge in the desired slot.
• Lock the mitre gauge at 0°.
• Proceed as for ripping.
Mitre cuts (fi g. A1)
• Set the mitre gauge to the required angle.
• Always hold the workpiece tightly against the face of the mitre gauge.
• Proceed as for ripping.
Compound mitre
This cut is a combination of a mitre and a bevel cut.
• Set the bevel to the angle required and proceed as for a cross-cut
mitre.
Support for long pieces
• Always support long pieces.
• Support long workpieces using any convenient means such as
saw-horses or similar devices to keep the ends from dropping.
Dust extraction (fi g. A2)
The machine is provided with a dust exhaust port at the rear of the
machine (14) suitable for use with dust extraction equipment featuring
57/65 mm nozzles. Supplied with the machine is a reducer port for use
of dust extraction nozzles of 34-40 mm diameter.
• During all operations, connect a dust extraction device designed in
accordance with the relevant regulations regarding dust emission.
• Ensure that the dust extraction hose in use is suitable for the
application and material being cut.
• Be aware that man-made materials such as chipboard or MDF
produce more dust particles during cutting than natural timber.

Cleaning
WARNING: To reduce the risk of serious personal injury,
turn unit off and disconnect machine from power source
before cleaning. An accidental start-up can cause injury.
To maintain correct operation of your saw, clean the throat plate area
regularly. Disassemble throat plate as shown and as described in the
instruction manual. Remove saw dust, chips and any other debris. If
using compressed air, always wear ANSI Z87.1 approved eye
protection.
The guard and throat plate must be placed in position before operating
the saw.
Before use,carefully inspect upper and lower blade guards as well as
the dust extraction tube to determine that it will operate properly. Ensure
that chips, dust or workpiece particles cannot lead to blockage of one of
the functions.
In case workpiece fragments are jammed between saw blade and
guards, disconnect the machine from the power supply and follow the
instructions given in section Mounting the saw blade. Remove the
jammed parts and reassemble the saw blade.
Keep the ventilation slots clear and regularly clean the housing with
a soft cloth.
• Regularly clean the dust collection system:
• Turn the saw on its side.
