Original instructions 4 SPEED MODELS 3 SPEED MODELS (230V & 110V models) DIAMOND CORE DRILLING MACHINE 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. 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. The correct power tool will do the job better and safer at the rate for which it was designed. Do not use the power tool if the switch does not turn it on and off.
Drill safety warnings • • • • • • • • • • • • • • • 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.
drilled; See also the instructions below under "Mounting to a Drilling Stand" INTRODUCTION This machine is for the intended purpose of diamond core drilling of concrete, masonry, stone and similar materials. It must always be mounted on a drilling stand. This machine is for professional use only and only trained personnel may operate this machine. All other uses which are not for the intended purpose are prohibited.
to test. Press the “Reset” button to energize the circuit to the machine. WARNING! 110V UK machines are not equipped with a PRCD portable residual current device or GFCI ground fault circuit interrupter. The machine must always be used with an isolating transformer for protection in case an electrical fault should occur. WARNING: Always connect the plug into the wall socket with a drip loop.
Sintered bits, also known as wet type, are much longer lasting but require operator knowledge for best results. Water is absolutely always required with sintered bits. The bit is impregnated with many layers of diamond in its metal matrix. As the matrix (bond) wears, new diamonds are exposed. If the bit becomes glazed, it can be resharpened by dressing with an appropriate alumina oxide or silicon carbide dressing stick.
CAUTION: Never attempt to change gears on a running machine! Only adjust when the machine is at rest. For 3 speed models, Select the desired gear range by turning the gear selector either clockwise or counterclockwise into the desired gear. It will usually be necessary to turn the spindle by hand a little to get it to shift all the way. For 4 speed models, turn the two gear selectors to the correct combination of A,B,C and D to reach the desired speed range. (see the chart below).
3. Using the bubble level, adjust the four leveling bolts to achieve a good level positioning, then fully tighten the center anchor bolt. The entire rig must be mounted solidly. WARNING: Never attempt to drill unless the stand is fixed securely beyond any doubt. 5) THE SWITCH 230V models: This machine has a rocker switch. Press the switch to the on position to turn on. Press the switch to the off position to turn off.
overload. 7) SAFETY CLUTCH This machine is equipped with a mechanical clutch to protect the operator and machine from excessive torque forces. When the preset maximum torque level is reached, the clutch will slip. Normally, the electronic overload will operate first. But if the load is very sudden or extreme, such as when the bit gets stuck, the clutch will operate first. After the clutch slips many times, it will become worn and slip at lower and lower torque levels.
ABOUT DIAMOND BITS The diamond impregnated segments in a wet type (sintered) diamond core bit operate on a principle of controlled erosion. The bond matrix holding the diamonds is continually worn away by abrasion with the work piece, exposing the harder diamonds to stand proud from the bond matrix. A bit with good diamond exposure is a sharp bit. This erosion process causes heat and particles, which require water to cool and rinse free. Without adequate water, the bit would overheat and be destroyed.
Another method is to stop and add about 6mm (1/4”) of coarse silica sand in the kerf and and drill for a few minutes, then turn up the water to rinse the sand free. Repeat as needed. 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.
Maintenance which should be performed by an authorized service center, include the following: • Replace water seals as needed. • Replace the carbon brushes as needed • Change the gear oil about every 100 hours of operation • Replace the clutch discs and spring as needed. Each year perform a full mechanical inspection, cleaning and re-lubrication. THE CARBON BRUSHES The carbon brushes are a normal wearing part and must be replaced when they reach their wear limit.
