Original instructions D-Handle Model Pistol-Handle Model CAUTION: Machine equipped with overheat thermal protection. When the thermal protection kicks in, always remove from the worpiece and run at no load for at least 3 minutes to allow motor to cool before returning to operation.

GENERAL SAFETY INSTRUCTIONS 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. 1) Work area safety a. b. c. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
g. away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards. 4) Power tool use and care a. b. c. d. e. f. g. Do not force the power tool. Use the correct power tool for your application.
DRILL SAFETY WARNINGS 1. 2. 3. Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury. Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock. 4.
All models are equipped with a mechanical safety clutch. All models have electronics for soft start, overload protection, thermal protection and a unique overload warning system. (see p.9) 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.
OPERATING INSTRUCTIONS Mounting the core bit CAUTION: Ensure that the threads of the spindle and the core bit match. Attempting to mount mismatched threads will result in damage to both threads. Ensure both the core bit and the machine spindle are clean. Any debris could cause excessive run-out of the mounted core bit. Excessive run-out can cause premature failure of the core bit and/or a safety hazard. Tighten the bit to the spindle using two wrenches.
Water should always be used to cool and lubricate the bit and to flush out abrasive particles formed while drilling. To connect the water supply. Attach the quick-release water coupling to a water hose. Open Water Feed Valve Closed 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.
THE SWITCH The machine has a lockable trigger switch. Squeeze the trigger to start the machine. To lock the switch on, press the lock button while holding the trigger switch on. To release, squeeze the trigger and release. WARNING: Never lock the switch on when drilling hand-held. Only lock the switch on when mounted to a rig.
1. Squeeze the trigger switch to turn the machine on. (For wet drilling models, press the "Reset" button on the PRCD interrupter device to engergize the circuit to the machine before starting.) WARNING: Hold the machine tightly with both hands to counteract the torque reaction force when the bit begins to turn. 2. 3. 4. 5. Very gently begin the cut. If holding by hand, start the cut by approaching at an angle of about 30 degrees to the cutting surface.
matrix (the diamonds not exposed) and the bit becomes dull (diamond segments polish smooth). This is called glazing and luckily the bit can be de-glazed (sharpened). If the bit seems to refuse to cut anymore, you know that it is glazed. See below: ”SHARPENING A GLAZED BIT ” Never use a sharp motion or the bit will be damaged. Conversely, don’t feed too gently or the diamond segments will become glazed. Keep the bit steadily working, but don’t be abusive or give the bit shock impacts into the work surface.
Another method is to drill into a cinder block. Repeat as needed. If that still does not work the only choice is to use a dressing stone. VIBRATION TROUBLESHOOTING If vibration occurs and it is not caused by embedded steel, stop drilling to find the cause and remedy. CAUTION: Do not operate with vibration or there will be serious hazard and the diamond core bit will surely be destroyed. Vibration is usually caused by: 1. A bit with too much runout SOLUTION: Replace bit. 2.
THE CARBON BRUSHES The carbon brushes are a normal wearing part and must be replaced when they reach their wear limit. This machine is equipped with auto-stop carbon brushes. If the machine comes to a stop unexpectedly, the brushes should be checked. The auto-stop brush design protects the motor by stopping the machine before the carbon brushes are completely worn out. Caution: Always replace the brushes as a pair. To replace: 1. 2. 3. 4. 5.
