Thermal Protection

After the machine has worked in overload for a period, a thermal protection circuit shuts off the machine to

protect the motor. If this occurs, always remove from the workpiece. The machine will again be operational after

the thermal protection has cooled down. The time of cooling down depends on the heat of the motor and the

ambient temperature.

1. Press the reset button to reset the thermal protection circuit once the core drill has cooled down sufficiently

(fig. 12).

Safety Clutch

The core drill is fitted with a mechanical friction clutch (safety clutch) to reduce kickback. If the diamond core bit

touches the reinforcing steel bar when drilling in reinforced concrete, or the motor is otherwise suddenly

overloaded, the core drill may start to vibrate. REDUCE THE PRESSURE OF DRILLING IMMEDIATELY.

If the diamond core bit catches and jams, the safety clutch will slip to protect the operator. If this happens, switch

off the drill and remove it from the power supply.

The mechanical clutch reduces kickback therefore following pro-longed and continuous jamming of the bit during

use it will become worn and slip at lower torque levels. When this happens, the clutch may need servicing.

WARNING! Hold the core drill tightly with both hands to counteract the torque reaction force when the

bit begins to turn. Be aware of the location of pipe work and wiring. When the bit grabs, the machine will

always twist in the counterclockwise direction. If you are drilling into the floor, make sure that the side

handle is in front of your left leg, never between your legs.

Core Drilling Tips

•

After tightening the diamond core bit connect the core drill to the power supply and lightly press the variable

speed trigger to check that the diamond core bit is rotating evenly.

•

Gently drill at a low speed until the core penetrates the surface approx. 5-10mm deep. If holding by hand,

start the cut by approaching at an angle of about 30 degrees to the cutting surface. (A large piece of wood

with a large V notch cut in it will help prevent the bit from wandering at the beginning). Once about a third of

the arc is cut, straighten the bit to the correct perpendicular angle while keeping enough feed pressure on

the bit to prevent it from wandering. If using a rig, use a very light feed pressure to prevent the bit from

wandering until the bit is fully penetrated into the cut.

WARNING! If the bit gets stuck, do not try to rock it loose by turning the variable speed trigger on

and off. That is hazardous and could damage the motor. Rather, unplug the machine and use a

wrench on the bit mounting to work it loose.

•

Reduce the drill speed just prior to the core bit breaks through the workpiece, the bit will be very liable to get

stuck. When breaking through, hold the machine tightly and reduce feed pressure.

WARNING! Keep the motor air vents free of dust to maintain ventilation and proper cooling of the

motor.

•

It is recommended that a lower speed should be used when drilling with larger core bits.

•

After shutting down and switching off the power supply, remove the core bit.

•

Clean core bit with clean with water after use.

Set-Up & Preparation – Stand

Fastening The Base

WARNING! It is essential to secure the base to the work surface to reduce the risk of injury and to

protect the core drill from damage. An unsecured core drill and stand could rotate during drilling, cause

the core bit to chatter against the work surface or bind in the hole, which can fracture the diamond

segments.

NOTE: The anchor bolt is not included, it’s not necessary but you can use one if needed.

Place the core drill stand on a solid, flat, and level surface

before mounting the core drill. When the core drill stand

can shift or rock, the power tool or workpiece cannot be

steadily and safely controlled.

The anchor sleeve (not included) is usually suitable for

fastening core drilling equipment to uncracked concrete.

Under certain conditions it may be necessary to use an

alternative fastening method.

1. To set the anchor sleeve, use an 16mm drill bit (not

supplied) suitable for concrete to drill the pilot hole.

Drill the pilot hole 50mm deep at 240mm from the

centre of the hole to be drilled.

2. Clear out as much concrete dust as possible and fit

the anchor sleeve inside the pilot hole.

3. Screw the anchor bolt into the anchor sleeve.

4. Place the slot in the base over the anchor bolt and

align the core drill stand.

5. Always be sure to level the base using the levelling

bolts at each corner of the base so that the core drill

bit contacts the workpiece squarely and cuts straight.

6. Place the large washer and screw the clamping nut

onto the anchor bolt.

7. Use a suitable open-end spanner (not included) to

tighten the clamping nut firmly. Take care to ensure

that the levelling bolts make firm contact with the

underlying surface.

Mounting the Core Drill

WARNING! Please read these mounting instructions in conjunction with the instruction manual for the

Core Drill.

WARNING! Ensure the power tool has been switched off and disconnected from the power supply and

completely stopped before performing any of the following operations.

WARNING! Securely fasten the power tool to the core drill stand before use. Power tool shifting on the

core drill stand can cause loss of control.

1. Remove the side handle on the core drill.

2. Tighten the carriage lock to prevent the carriage from moving when installing the core drill (fig. 4).

mask when performing this procedure.

•

If the enclosure of the diamond core drill requires

cleaning, do not use solvents but a moist soft cloth

only. Never let any liquid get inside the diamond core

drill; never immerse any part of the diamond core drill

into a liquid.

•

Ensure the shoulder support with shoulder support

pad are fitted securely onto the diamond core drill.

Regularly check and tighten the four screws if

necessary (fig. 13).

•

Your power tool requires no additional lubrication.

Carbon brushes

When the carbon brushes wear out, the core drill will spark and/or stop. Discontinue use as soon as this

happens. They should be replaced prior to recommencing use of the core drill. Carbon brushes are a wearing

component of the core drill, therefore not covered under warranty. Continuing to use the core drill when the

carbon brushes need to be replaced may cause permanent damage to the tool. Carbon brushes will wear out

after many uses but when the carbon brushes need to be replaced, take the core drill to an electrician or a

qualified power tool repairer for a quick and low-cost replacement. Always replace both carbon brushes at the

same time.

Note: manufacturer will not be responsible for any damage or injuries caused by the repair of the core

drill by an unauthorised person or by mishandling of the core drill.
