Intended Use; Unpacking Your Tool; Before Use; Operation - GMC GMCI250 Traduction Des Instructions Originales

Intended Use

• Hand-held circular saw intended for horizontal cutting and slotting of mineral
materials, such as marble, using a suitable liquid coolant (water).
WARNING: DO NOT use this machine for cutting wood, plastic or metal, or reinforced
concrete.

Unpacking Your Tool

• Carefully unpack and inspect your new sander. Familiarise yourself with all its
features and functions
• Ensure that all parts of the tool are present and in good condition. If any parts are
GB
missing or damaged, have such parts replaced before attempting to use this tool

Before Use

WARNING: Ensure the tool is disconnected from the power supply before attaching or
changing any accessories, or making any adjustments.
Adjusting the cutting angle
1. Loosen the Bevel Angle Adjuster Wing Nut (9)
2. Tilt the Base Plate (10) sideways, until the desired cutting angle is set on the
Cutting Angle Scale (11)
3. Tighten the Bevel Angle Adjuster Wing Nut
Note: For bevel cuts, the cutting depth is smaller than the setting indicated on the
Cutting Depth Scale (4).
Adjusting the cutting depth
WARNING: Ensure the machine is switched off and disconnected from the power
supply before adjusting the cutting depth.
Note: ALWAYS adapt the cutting depth to the thickness of the workpiece. For optimum
results, the Cutting Wheel (14) should protrude approximately 2mm out of the material.
1. Loosen the Cutting Depth Adjuster Wing Nut (5)
2. Adjust the desired cutting depth at the Cutting Depth Scale (4)
3. Tighten the Cutting Depth Adjuster Wing Nut
Cutting Marks
• The 0° cutting mark (7) indicates the position of the diamond cutting disc for right-
angled cuts
• The 45° cutting mark (8) indicates the position of the diamond cutting disc for 45°
cuts
Connecting the coolant hose
Note: This tool is designed to be used with a liquid coolant, i.e. water. Failure to do so
will cause the Cutting Wheel (14) to become blunt prematurely, and will produce an
inferior surface finish on the workpiece.
1. Connect the Coolant Hose (22) to the Coolant Connector (21)
2. Connect the Water Hose Connector (23) to a suitable hose pipe that connects to
your water mains
3. When you are ready to start cutting, open the Coolant Valve (20), then carefully
open the mains water tap, so the Coolant Hose fills with water
4. Use the Coolant Valve to adjust the amount of water needed to achieve good
coolant coverage of the Cutting Wheel (14) and cutting area
5. When work is finished, switch off the tool, then close the mains tap, leave the
Coolant Hose to run empty, then close the Coolant Valve and disconnect the hose

Operation

WARNING: ALWAYS wear eye protection, adequate respiratory and hearing
protection, as well as suitable gloves, when working with this tool.
WARNING: ALWAYS check the Cutting Wheel (14) before use. The Cutting Wheel
must be mounted properly and rotate freely. Carry out a test run for at least one minute
without any load. DO NOT use diamond cutting discs that are damaged, unbalanced,
or vibrate. Damaged Cutting Wheels can rupture and cause severe injuries.
WARNING: Exercise caution when cutting slots in load-bearing building structures;
refer to 'Masonry Saw Safety'.
Switching on and off
• To start the machine, press the On/Off Trigger Switch (1)
Note: To lock the On/Off Trigger Switch (1) in the 'On' position, press the Lock-On
Button (2).
• To switch off the machine, release the On/Off Trigger Switch, or when the Lock-On
Button is locked, briefly press the On/Off Trigger Switch and then release it
Direction of cut
• This machine must ALWAYS work in an up-grinding motion, as it may otherwise
be pushed out of the cut uncontrollably, potentially leading to severe injury and
damage
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. Briefly cutting into abrasive material (e. g.
lime-sand brick) can temporarily sharpen the wheel again
Accessories
• A range of accessories and consumables, including spare wheels, is available from
your GMC stockist. Spare parts can be obtained from toolsparesonline.com
