and for the right side adjustment use 45° Right Bevel Bolt (59) and 45° Right Bevel Locking Nut (58). Loosen
the applicable locking nut so it is at a higher position, and make a small adjustment to the bolt height (the
adjustment should be very small)
3. Recheck the 45° angle (see ‘Checking 45° angles’) and repeat steps if necessary until the 45° stop positions
are correct for both sides
Note:
In use make sure the top of the bolts are kept clear of chippings otherwise the cutter head will not rest at
the correct angle.
Note:
The Bevel Angle Gauge (62) is only approximate. An adjustment can be made to the Bevel Angle Indicator
(61) using the Bevel Angle Indicator Screw (60) so it reads exactly 45° but it can lead to the alternate 45° side
indication being slightly out.
Mitre Angle 90° Adjustment
The major adjustment of the mitre angle 0° position is achieved by altering the Fence (22) position
1. Loosen the Mitre Table Locking Knob (15) by turning anti-clockwise and lift the Click-Stop Lever (16)
2. Rotate the Mitre Table (21) with the Operating Handle (4) to the 0° position using the Mitre Angle Indicator
(18) and Mitre Angle Gauge (20)
3. Retighten the Mitre Table Locking Knob to lock the angle setting
4. 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)
5. Use a set square to check the 90° angle between the Fence (22) and the Saw Blade (10) - see Image B
6. Adjust the position of the Fence by loosening the 4 Fence Bolts (38) with the Fence Hex Key (71) so the
Fence is at exactly 90° using the set square. Remove the Small Fence (29) by loosening the Small Fence
Knob (37) to access 2 of the screws that it will be concealing.
7. Retighten the 4 Fence Bolts
8. Release the Latching Pin and allow the cutter head to return to its top position
Replacing the Throat Plate
IMPORTANT:
If the Throat Plate (13) is damaged or heavily worn, it must be replaced to ensure safe operation of
the tool. To replace the Throat Plate:
1. If necessary to remove the Throat Plate, the remove the Small Fence (29) secured by the Small Fence Knob
(37) and unscrew and remove the 4 Fence Bolts (38) with the Fence Hex Key (74) and remove the Fence (22).
2. Unscrew the Throat Plate Screws (14) securing the Throat Plate and remove the Throat Plate
3. Clean the Blade Channel (12) and fit the new Throat Plate. Refit and tighten the Throat Plate screws
4. If previously removed refit the Fence back to the correct position and refit the Fence Bolts (38). Ensure the
Fence is at the correct angle with a set square before tightening the Fence Bolts following ‘Mitre Angle 90°
Adjustment’
General inspection
• Regularly check that all the fixing screws are tight
• Inspect the supply cord of the tool, prior to each use, for damage or wear. Repairs should be carried out by
an authorised GMC service centre. This advice also applies to extension cords used with this tool
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly, and shorten the
machine’s service life. Clean the body of your machine with a soft brush, or dry cloth. If available, use clean,
dry, compressed air to blow through the ventilation holes
• Clean the tool casing with a soft damp cloth using a mild detergent. Do not use alcohol, petrol or strong
cleaning agents
• Never use caustic agents to clean plastic parts
Lubrication
• Slightly lubricate all moving parts at regular intervals with a suitable spray lubricant
Brushes
• Over time the carbon brushes inside the motor may become worn
• Excessively worn brushes may cause loss of power, intermittent failure, or visible sparking
• To replace the brushes, remove the Brush Access Covers (11) from both sides of the machine. Remove the
worn brushes and replaced with new. Replace Brush Access Covers. Alternatively, have the machine serviced
at an authorised service centre
Note:
Always replace carbon brushes in pairs.
Storage
• The cutting head can be lowered and secured by the Latching Pin (46) to make the saw a smaller size for
storage. Store this tool carefully in a secure, dry place out of the reach of children
Disposal
Always adhere to national regulations when disposing of power tools that are no longer functional and are
not viable for repair.
• Do not dispose of power tools, or other waste electrical and electronic equipment (WEEE), with
household waste
• Contact your local waste disposal authority for information on the correct way to dispose of power tools
