3. Rotate the mitre table (21) until the mitre angle in-
dicator (18) aligns with the desired angle on the mitre
angle gauge (20).
4. Retighten the mitre table locking knob.
WARNING: Be sure to tighten the mitre table locking
knob before making a cut. Failure to do so could result
in the table moving during the cut, causing serious
personal injury.
5. Loosen the bevel angle lock (17) and move the cut-
ter head to the left to the desired bevel angle (between
0° and 45° as indicated by the bevel angle indicator
(61)). Tighten the bevel angle lock.
6. Place the workpiece flat on the table with one edge
securely against the fence (22). If the board is warped,
place the convex side against the fence. If the concave
side is placed against the fence, the board could break
and jam the blade.
7. When cutting long pieces of timber, support the op-
posite end of the timber with workpiece supports (25),
a roller stand or a work surface that is level with the
saw table.
8. Use the clamp to secure the workpiece wherever
possible using the clamp base (27) against the work-
piece and adjusting the height with the clamp knob
(29).
NOTE: The clamp can be positioned on the other side
of the saw using the clamp mounting (45) and moving
the clamp mounting knob (39) to the other clamp
mounting knob thread (44).
9. Before turning on the saw, perform a dry run of the
cutting operation to check that there are no problems.
10. Hold the operating handle (4) firmly and depress a
safety lock-off (2 or 3) and squeeze the on/off trigger
switch (49). Allow the blade to reach maximum speed.
11. Press the release lever (5) and slowly lower the
blade into and through the workpiece.
12. Release the on/off trigger switch and allow the
saw blade to stop rotating before raising the blade out
of the workpiece. Wait until the blade stops before re-
moving the workpiece.

12. ACCESSORIES

• A range of accessories and consumables, including
saw blades, additional clamps and personal protective
equipment, is available from your GMC stockist.

13. MAINTENANCE

WARNING: Always disconnect from the power supp-
ly before carrying out any inspection, maintenance or
cleaning.
13.1 Bevel angle adjustment
• Checking angle
1. Turn the bevel angle lock (17) anti-clockwise and
position the cutter head at the maximum height with
the bevel angle indicator (61) at 0° on the bevel angle
gauge (62). Tighten the bevel angle lock.
2. Lower the cutter head so the exposed blade is in the
blade channel (12) of the throat plate (13) and lock in
this position with the latching pin (46).
3. Recheck that the cutter head is upright and the bevel
angle indicator is still at 0°.
4. Place a set square on the table with one short edge
against the mitre table (21) and the other short edge
against the blade (avoiding the saw teeth) - see fig A.
NOTE: If the blade is not square (90°) with the mitre
table, adjustment is required.
• Changing 0° angle
1. Use 0° bevel adjustment bolt (59) and 0° bevel
adjustment locking nut (58) to set the cutter head res-
ting position at exactly 0°.
2. Turn the bevel angle lock (17) anti-clockwise and
set the bevel angle to 45° then tighten the bevel angle
lock.
3. Turn the bevel adjustment locking nut on the 0°
bevel adjustment bolt so it is at a higher position, and
make a small adjustment to the bolt (the adjustment
should be very small).
4. Turn the bevel angle lock (17) anti-clockwise and
set the bevel angle to the 0° resting position then tigh-
ten the bevel angle lock.
5. Recheck the 90° alignment against the set square
and blade.
6. Repeat the above steps 2-4 until a 90° angle is
achieved.
7. Tighten the bevel angle lock.
8. A minor adjustment can be made to the bevel angle
indicator (61) by loosening the bevel angle indicator
screw (60) and adjusting the position of the bevel ang-
le indicator so it is set to 0° when the set square is at a
90° angle (Fig A).
NOTE: To adjust the 45° bevel stop position use the
bevel angle stop locking nut (32) and bevel angle stop
bolt (31) using the 45° side of a set square adapting
the same procedure as above.
13.2 Mitre angle 90° adjustment
The major adjustment of the mitre angle 90° position
is achieved by altering the fence (22) position.
1. Loosen the mitre table locking knob (15) by turning
