1. Loosen the Depth Adjustment Locking Nut and turn the Depth Adjustment Bolt (67) clockwise for a shallower
cut or anti-clockwise for a deeper cut. The bolt contacts the Depth Stop (70) in use as the cutter head is
lowered
2. Check the height adjustment repeatedly to ensure the blade will not contact the bottom of the Blade Channel
(12) or the sides of the Throat Plate (13) when doing a bevel cut. Check both left side and right side bevel cuts
3. Retighten the Depth Adjustment Locking Nut
Adjusting the mitre angle
The Mitre Table Locking Knob (15) is used to lock the Mitre Table (21) at the desired mitre angle. The mitre
saw cuts from 0° to 45° both left and right. To adjust the mitre angle:
1. Turn the Mitre Table Locking Knob anti-clockwise to loosen
2. Rotate the mitre angle with the Operating Handle (4) to the desired position using the Mitre Angle Indicator
(18) and Mitre Angle Gauge (20). The Mitre Table features positive click stops at 0, 15, 22.5, 30 and 45°
both left and right for quick setting of common mitre angles. Lift the Click-Stop Lever (16) to bypass the
click stop positions
3. Retighten the Mitre Table Locking Knob to lock the angle setting
WARNING:
Be sure to tighten the Mitre Table Locking Knob before making a cut. Failure to do so could result
in the Mitre Table moving during the cut and cause serious personal injury.
Adjusting the bevel angle
The Bevel Angle Lock (17) is used to set the blade at the desired bevel angle. The mitre saw bevel cuts from
0° to 45° to the left or right. To adjust the bevel angle:
1. Ensure the Mitre Table Locking Knob (15) is tight
2. Loosen the Bevel Angle Lock by rotating anti-clockwise
3. Tilt the cutter head with the Operating Handle (4)
4. Use the Bevel Angle Indicator (61) and Bevel Angle Gauge (62) to set the required angle
5. Retighten the Bevel Angle Lock to secure in position
WARNING:
Be sure to tighten the Bevel Angle Lock before making a cut. Failure to do so could result in the
saw arm moving during the cut and cause serious personal injury.
Note:
Adjust the Bevel Nut (40) if necessary to ensure smooth operation of the Bevel Angle Lock or sufficient
tension to hold the Bevel Angle.
Note:
Use the 0° Stop (65) to configure the mitre saw for left side only bevel cuts and create a stop at the
vertical 0° position. To enable move the leg out (as shown) while the cutter head is tilted to the left side.
Operation
WARNING:
ALWAYS wear eye protection, adequate respiratory and hearing protection, as well as suitable
non-woven gloves, when working with this tool.
Switching on and off
• To turn the saw on, depress a Safety Lock-Off (2 or 3) and hold in the On/Off Trigger Switch (49)
• To turn the saw off, release the On/Off Trigger Switch
Laser and LED worklight
• To switch the laser on and off use the Laser On/Off Switch (73). This indicates the cut line on the workpiece
• To switch the LED worklight on and off use the Worklight On/Off Switch (72). It provides additional illumination
of the cutting area
Note:
Both laser and LED worklight can be used together and are powered independently of the mitre saw On/
Off Trigger Switch (49).
Making a cut
• A compound mitre cut involves using a mitre angle and a bevel angle at the same time. It is used to make
picture frames, cut mouldings, make boxes with sloping sides, and for roof framing
• Always make a test cut on a piece of scrap wood before cutting the workpiece
1. Pull on the Release Lever (5) and lift the cutter head to its full height
2. Loosen the Mitre Table Locking Knob (15)
3. Rotate the Mitre Table (21) until the Mitre Angle Indicator (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 cutter head to the left to the desired bevel angle (between 0°
and 45° (left or right) 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. The Small Fence (29) can be fitted to either side of the Fence (22) and secured using the
Small Fence Knob (37) to increase support on the required side
7. When cutting long pieces of timber, support the opposite 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 (30) to secure the workpiece wherever possible using the Clamp Base (27) against the
workpiece and adjusting the height with the Clamp Mounting Knob (39)
Note:
The clamp can be positioned on the other side of the saw using the Clamp Mounting (45) and moving the
Clamp Mounting Knob 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 (10) to stop rotating before raising the blade out
of the workpiece. Wait until the blade stops before removing the workpiece

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

Maintenance
WARNING:
ALWAYS disconnect from the power supply before carrying out any inspection, maintenance
or cleaning.
Bevel Angle Adjustment
Checking 0° angle
1. Turn the Bevel Angle Lock (17) anti-clockwise
2. Tilt the cutter head to the left and raise the 0° Stop (65)
3. Position the cutter head at maximum height against the 0° Stop. The Bevel Angle Indicator (61) should be at
0° on the Bevel Angle Gauge (62). Tighten the Bevel Angle Lock
4. Lower the cutter head so the exposed Saw Blade (10) is in the Blade Channel (12) of the Throat Plate (13) and
lock in this position with the Latching Pin (46)
5. Recheck that the cutter head is upright and the Bevel Angle Indicator is still at 0°
6. Place a set square on the table with one short edge against the Mitre Table (21) and the other short edge
against the Saw Blade (avoiding the saw teeth) (Image A)
Note:
If the blade is not square (90°) with the Mitre Table, adjustment is required
Changing 0° angle
1. Use the 0° Bolt (63) and 0° Locking Nut (64) to set the cutter head resting position at exactly 0° while against
the 0° Stop (65) using a square against the surface of the Saw Blade (10) and Mitre Table (21) (Image A)
2. After this adjustment 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 Angle Indicator so it is set to 0° when the
blade surface is at a perfect 90° angle to the mitre table surface
Checking 45° angles
1. Turn the Bevel Angle Lock (17) anti-clockwise and using the Operating Handle (4) set the bevel angle to 45°
left as indicated by the Bevel Angle Indicator (61) and Bevel Angle Gauge (62). The cutter head should stop at
exactly 45° due to the 45° Left Bevel Bolt (31) set height
2. Retighten the Bevel Angle Lock
3. Use the 45° side of a square or similar accurate angle measuring tool to check the angle (Image C). Use a
parallel shorter spacer if the 45° side is too long to rest against the side of the blade, typically a metal block
4. Loosen the Bevel Angle Lock and make sure while the blade surface is touching the 45° side of the square the
Bevel Angle Indicator is reading 45°. If not, correct adjustment will be required
• Use the same procedure for checking the right bevel 45° angle. Ensure the 0° Stop (65) is set down and move
the square to the right side of the blade again using a spacer if necessary
Changing 45° angle
1. Turn the Bevel Angle Lock (17) anti-clockwise and set the bevel angle to 0° then tighten the Bevel Angle Lock
2. For adjustments to the left 45° stop position use 45° Left Bevel Bolt (31) and 45° Left Bevel Locking Nut (32)
