Checking and adjusting the 45° bevel position in mitre mode
(fig. M1 & M2)
• Ensure that the sawhead is to its extreme left-hand position with the
bevel clamp handle locked.
• Release and retract the lower guard.
• Check the angle from the blade to the table with a suitable protractor.
It should be 45° (fig. M1).
• If adjustment is required, proceed as follows:
• Adjust the grub screw (78) as required. The grub screw is self-locking
(fig. M2).
Assembly for saw bench mode
Changing from mitre saw to saw bench mode
(fig. A1, A3, E2, G, N1 & N2)
Check that the depth limiter is disengaged. Refer to the
section "Adjusting the mitre saw mode depth limiter (fig. G)".
• Put the blade into 0° cross-cut position with the rotating table location
plunger (8) correctly located and the rotating table clamp (17) secured
(fig. A1).
• Slacken the riving knife clamp knob (27) just enough to allow the riving
knife to swing downwards (fig. N1).
• Slide the riving knife bracket (79) to the right so that the narrow part on
the right locates in the slot provided in the casting and tighten the
clamp knob.
• Remove the under-table guard.
• Pull down the sawhead and swing the height adjuster (22) until its
U-shaped bracket (54) engages on the pin provided in the base (fig. E2).
• Turn the wheel (53) of the adjuster to make the blade and riving knife
protrude from the saw bench table (31) (fig. A3) to provide maximum
cutting depth in saw bench mode.
The blade should not foul the lower blade guard.
• Pull the table release lever (19) to the left, lift the front edge of the table and
flip it back through 180° until the teeth of the table-locking device (26)
automatically engage the saw blade retention lever to secure it in the
saw bench mode (fig. N2).
Adjusting the riving knife (fig. A2, F3 & O)
In the mitre saw mode, the riving knife (30) must be adjusted up and out of
the way by unscrewing the clamp knob (27) and moving the riving knife
until it can be rotated up (fig. F3).
In the saw bench mode, the correct position is for the top of the riving
knife (30) to be no more than 2 mm below the highest tooth of the blade (59)
and the body of the radius to be a maximum of 3-8 mm from the tips of
the saw blade teeth. Also the riving knife must be completely in line with
the rear of the saw blade (fig. O).
• If adjustment is required, proceed as follows:
• Unlock the clamp knob (27), slide the knob forwards or backwards in
its slot and tighten the clamp knob (fig. A2).
• The bracket securing the riving knife to the machine must be at
least 3 mm away from the blade teeth.
• Always check that the riving knife clamp knob is tightly secured.
Fitting the upper blade guard (fig. P)
The upper blade guard (29) is designed to be quickly and easily attached,
via a spring-loaded plunger (80) to the hole (81) in the riving knife (30) once
it has been positioned through the worktable for saw bench mode.
• Secure the upper blade guard (29) to the riving knife by pulling the
knob (82) to allow the plunger in the guard to engage.

Never use your saw in saw bench mode without the upper
guard correctly fitted.
Mounting and adjusting the parallel fence (fig. Q)
The dual height parallel fence (33) can be used in two positions (10 or 62 mm).
The parallel fence can be mounted on either side of the blade. To turn the
fence into the appropriate position, proceed as follows:
• Loosen the knob.
• Pull out the bracket (84) and replace it on the other end.
• Slide the bracket on from the left or the right. The clamping plate (85)
engages behind the front edge of the table.
• Check that the fence is parallel to the blade. If not, then adjust as follows.
• Loosen the Allen screw (86).
• Adjust the fence so that it is parallel to the blade by checking the distance
between the blade and the fence at the front and rear of the blade.
• When the adjustment has been carried out, re-tighten the Allen screw
and check again that the fence is parallel to the blade.
• Tighten the knob (83).
• Use the 10 mm profile for ripping low workpieces to allow
access between the blade and the fence for the push stick.
• The rear end of the fence should be level with the front of the
riving knife.
Changing from saw bench to mitre saw mode (fig. D, E1 & E2)
• Remove the parallel fence (33).
• Turn the wheel (53) of the height adjuster (22) to provide maximum
cutting depth in mitre saw mode (fig. E2).
• Proceed as described in the section "Turning the sawhead and table
over (fig. E1 & E2)".
• Adjust the riving knife up and out of the way.
• Replace the under-table guard (48) (fig. D).
Remember to use the depth stop limiter for all angles except
0-45° mitre cross cut.
Instructions for use
• Always observe the safety instructions and applicable regulations.
• The attention of UK users is drawn to the "woodworking
machines regulations 1974" and any subsequent amendments.
• Ensure the material to be sawn is firmly secured in place.
• Apply only a gentle pressure to the tool and do not exert side
pressure on the saw blade.
• Avoid overloading.
Prior to operation:
• Install the appropriate saw blade. Do not use excessively worn blades.
The maximum rotation speed of the tool must not exceed that of the
saw blade.
• Do not attempt to cut excessively small pieces.
• Allow the blade to cut freely. Do not force.
• Allow the motor to reach full speed before cutting.
• Make sure all locking knobs and clamp handles are tight.
Switching on and off (fig. A1)
This machine has two independent switching systems. In saw bench
mode, the on/off switch (1) is used. In mitre saw mode, the trigger switch
(1A) is used (fig. A1).
Saw bench mode (fig. R)
The on/off switch used in saw bench mode has a no-volt release function:
should the power be shut off for some reason, the switch has to be
deliberately reactivated.
