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 • • • • • • • • • • • • • • • Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss. NOTE The above warning applies only to impact drills and may be omitted for drills other than impact drills. 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.
times. It is equipped with a three speed mechanical gearbox for different core drill size ranges and features a mechanical safety clutch. The motor has electronics for soft start, overload protection and thermal (overheating) protection. There is an indicator light on the machine to alert the operator of load and temperature conditions. ELECTRICAL CONNECTION The network voltage must conform to the voltage indicated on the tool name plate.
OPERATING INSTRUCTIONS 1) 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. The spindle has two types of threads. The outside male thread is 1-1/4inch UNC, the inside female thread is 1/2 inch BSP. Ensure both the core bit and the machine spindle are clean. Any debris could cause excessive run-out of the mounted core bit.
To connect the water supply. Attach the quick-release water coupling to a water hose. 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). CAUTION: There are two small holes on the top of the gearcase.
4) THE SWITCH Lock Button 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. Trigger Switch WARNING: Never lock the switch on when drilling hand-held. Only lock the switch on when mounted to a rig.
7) DIAMOND CORE DRILLING WARNING: When coring through a floor, the core will fall down. Take precautions to avoid injury or damage below. NOTE: When drilling with a new bit for the first time, use less than normal feed pressure for a time until it breaks-in. 1. Press the “Reset” button on the PRCD interrupter device to energize the circuit to the machine. Then squeeze the trigger switch to turn the machine on.
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 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.
• • 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. This machine is equipped with auto-stop carbon brushes. If the machine comes to a stop unexpectedly, the brushes should be checked.
