CONCRETE SAW Warning: On tools equipped with over load protection, when motor has been cut off due to over load, always switch on machine with no load for at least 3 minutes to reduce temperature before returning to operation to avoid burn out of the motor. ORIGINAL INSTRUCTIONS For your personal safety, READ and UNDERSTAND before using. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.

GENERAL POWER TOOL SAFETY WARNINGS WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your mains operated (corded) power tool or battery-operated (cordless) power tool. General Power Tool Safety Warnings - Work Area Safety a. b. c. Keep work area clean and well lit.
d. e. f. g. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

Keep hands away from cutting area and the blade.
i. j. k. l. m. n. o. p. power tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting and installing the wheel, position yourself and bystanders away from the plane of the rotating wheel and run the power tool at maximum no load speed for one minute. Damaged wheels will normally break apart during this test time. Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses.
b. c. d. e. f. g. h. i. j. Never place your hand near the rotating accessory. Accessory may kickback over your hand. Do not position your body in line with the rotating wheel. Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging. Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.
GROUNDING INSTRUCTIONS 1. 2. All grounded, cord-connected tools: In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
ELECTRICAL CONNECTION The network voltage must conform to the voltage indicated on the tool name plate. Under no circumstances should the tool be used when the power supply cable is damaged. A damaged cable must be replaced immediately by an authorized Customer Service Center. Do not try to repair the damaged cable yourself. The use of damaged power cables can lead to an electric shock. WARNING: Never operate a damaged machine.
DIAMOND BLADES Allowed Types Of Blades This machine may use diamond blades or abrasive wheels. • • • • Only use either segmented or continuous rim diamond blades. If the diamond blades are segmented, the maximum allowable peripheral gap between segments is 10mm and must be with a negative rake angle. Only diamond blades of 355mm (14”) or less may be used. Blade thickness must be at least 2.0mm and no greater than 6.
glazing and luckily the blade can be de-glazed (sharpened). If the blade seems to refuse to cut anymore, you know that it is glazed. See below: ”Sharpening a Glazed Blade” Never use a sharp motion or the blade will be damaged. Conversely, don’t feed too gently or the diamond segments will become glazed. Keep the blade steadily working, but don’t be abusive or give the blade shock impacts into the work surface. Take great care to keep the blade perpendicularly aligned to the kerf.
Inspect the blade before use. It must not be cracked, warped or damaged in any way that would cause a hazard in operation. Loose diamond segments can be ejected at high speed, causing possible injury. Always check that the diamond segments are not under cut. If the diamond segments are thinner or nearly thinner than the blade core, the kerf will be too tight fitting and could easily lead to kickback. Ensure that the flanges and blade bore are clean and undamaged and that everything fits properly.
WARNING: Always use the PRCD (GFCI) when operating with water WARNING: Never allow water to enter the motor. It could lead to an electric shock. WARNING: Check all connections of the water feed system to ensure there are no leaks. Inspect hoses and other critical parts which could deteriorate. WARNING: The maximum water pressure should not exceed 70 psi (4 bar). Open Water Feed Valve Closed Use a water collector with a wet vacuum to collect cooling water if nearby objects could be damaged by water.
the motor. Always run the machine at no load for a few minutes to return to a normal operating temperature before continuing. CAUTION: The motor will be damaged if it is repeatedly overloaded or overheated. Always cool the motor by running at no load for a few minutes whenever it stops from either overheat or overload. OPERATION How to hold the machine • • • • • • Always hold the machine with both hands, with the right hand on the main handle and with the left hand on the side handle.
Cutting Technique • • • • • • • • • • • Holding the machine with both hands to resist the start up torque, press the release button and then squeeze the trigger switch. Allow the machine to reach full speed before contacting the workpiece. Adjust the water flow as needed by turning the water feed valve. Then gently begin the cut with the rear portion of the blade until the kerf is established.
pin can insert fully, then turn 90 degrees to lock in place. Ensure that it pivots freely. finally, attach the vacuum hose. Removal is the opposite of mounting. Note: Always ensure the vacuum cleaner's dust bag is not too full. An overfilled dust bag will have reduced dust collection efficiency which could result in poor dust control. MAINTENANCE AND CLEANING This machine operates in a very harsh environment.
