I PREPARATION A. Safety Precautions IMPORTANT! THE FOLLOWING SAFETY PRECAUTIONS MUST BE OBSERVED. 1. Know your core drilling machine! Read the Operator’s manual carefully. Learn the operation, application and limitations, as well as the specific potential hazards peculiar to this equipment. 2. Ground the machine! The core drill must be grounded while in use to protect the operator from electric shock. The motor is equipped with a three prong grounding type plug to fit the proper type receptacle.
I PREPARATION B. General Information The Dr520 & Dr620 core drills are available with different power units. MANUFACTURER MILWAUKEE Cardi MILWAUKEE AMPS 15 20 20 VOLTS 115 115 115 PHASE SINGLE SINGLE SINGLE HERTZ 60 60 60 All motors are single phase with two-speed selector switches. The 115 volt motors will operate within a power range of 110 to 120 volts. C. Bit Installation The threads on the output spindle of the core drill motors have dimensions of 1-1/4"-7.
I PREPARATION E. Electrical Supply The DR520 & DM620 core drills are furnished with 115 volt, single phase motors. These motors operate within a power range of 110 to 120 volts. Serious damage can result if the supply line voltage does not fall within this range.
II OPERATION A. Core Drill Positions To position the core drill: 1. Roll the drill so that the spindle is positioned over the desired drilling location. 2. Using the leveling screws located on the four corners of the base, level the core drill to insure that the bit will drill a straight, vertical hole. ÖCEILING BRACING - can be used when the ceiling above the work area is strong enough to provide solid bracing.
II OPERATION C. Vacuum Hold Down Operation The vacuum hold down base and pump work together to seal the drill to the work surface. The vacuum pump requires 115 volt electrical supply. A 115 volt accessory outlet located on the switch box is used to supply power to the vacuum pump. One outlet is consistently supplied with power so that turning the motor off does not turn off the vacuum pump and release the drill from the work surface. 1. Mount the column and carriage in the large vacuum hold down base. 2.
III. MAINTENANCE AND COMPONENT DESCRIPTION A. Motor Specifications Cardi Specifications MFR MODEL VOLT AMP Cardi D3-250 120 20 MOTOR RPM LOW HIGH GEAR GEAR 420 860 BIT CAPACITY IN LOW HIGH GEAR GEAR 8"-10" 4"-7" *Refer to motor owners manual supplied with drill for required motor maintenance. The Cardi motor is designed to operate at two speeds. Changing speeds is accomplished by using the speed shift knob built into the gear case of the unit.
III. MAINTENANCE AND COMPONENT DESCRIPTION The vacuum pump is used with the large vacuum hold down base to secure the core drill on smooth evenly textured surfaces. The pump is powered by a 115 volt, 4.2 amp, 60 hertz electric motor. The COMBINATION BASE power cord of the pump is plugged into the live outlet of the receptacle in the switch box of the core drill.
III. MAINTENANCE AND COMPONENT DESCRIPTION D. Gibs The gibs are brass wear shims used on the inside of the carriage which allow the carriage to slide freely and rigidly on the column. The gibs require periodic replacement. Replacing the gibs is necessary when the carriage is no longer rigid on the column. Keeping the column free of excess debris and burrs will maximize the service life of the gibs. E. Motor Spindle The motor spindle on all core drill motors is equipped with 1-1/4"-7 thread dimensions.
