Notes:
• DO NOT strain the machine so heavily that it comes to a standstill
• For cutting-depths greater than 20mm in hard materials, e.g., concrete, cut in
several steps, so the motor is not overloaded
• Clamp the workpiece if it does not remain stationary due to its own weight
• The machine should only be used for wet cutting
• This tool is intended for horizontal operation only
• NEVER apply sideways pressure to the Cutting Wheel (14)
• For cutting especially hard material (e.g. concrete with high pebble content), the
Cutting Wheel can overheat and become damaged as a result. This is clearly
indicated by circular sparking, rotating with the Cutting Wheel. In this case, interrupt
the cutting process and allow the Cutting Wheel to cool, by running the machine for
a short time at maximum speed with no load
• Noticeable decreasing work progress and circular sparking are indications of a
Cutting Wheel that has become dull. Briey cutting into abrasive material (e. g. lime-
sand brick) can temporarily sharpen the wheel again
Accessories
• A range of accessories and consumables, including GMC 950392 Marble Cutting
Blade, 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.
General inspection
• Regularly check that all the xing 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
Replacing the Cutting Wheel (see g. A)
WARNING: ALWAYS wear suitable cut-proof gloves when mounting and replacing
cutting wheels.
WARNING: The Cutting Wheel (14) becomes very hot during operation. DO NOT
touch it until it has cooled down.
WARNING: ONLY t a stone/marble cutting wheel of the same diameter and bore as
listed in the specication.
Removing Cutting Wheel:
1. Hold the Outer Flange (15) with the Ring Spanner (16)
2. Loosen the Wheel Bolt (17) with the Hex Key (18)
3. Remove the Outer Flange and Cutting Wheel (14) from the Drive Spindle (12)
Fitting Cutting Wheel:
1. Ensure the new Cutting Wheel (14), the Inner and Outer Flange (13 + 15) and the
Wheel Bolt (17) are clean
2. Fit the Inner Flange (13) on to the Drive Spindle (12)
3. Place the new Cutting Wheel (14) on to the Inner Flange
Note: The directional arrow on the Cutting Wheel (14) must match the direction of
rotation arrow on the Blade Guard (6).
4. Mount the Outer Flange (15) on to the Drive Spindle (12), and t the Wheel Bolt
(17)
5. Hold the Outer Flange with the Ring Spanner (16), and tighten the Wheel Bolt
using the Hex Key (18)
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
• If you suspect that the brushes may be worn, have them replaced at an authorised
GMC service centre
Note: One set of spare carbon brushes is supplied with this tool.
