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
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 in the Lock-Off Button (2) and press the On/Off Trigger
Switch (1)
• To switch off the machine, release the On/Off Trigger Switch
Note: As a safety feature the On/Off Trigger cannot be locked into the 'on' position.
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
