Electric Core Drill with Base

Set-Up and Operation

Ground Fault Circuit Interrupter (GFCI)

The machine MUST be connected to a properly earthed 240VAC mains electrical socket. Do

NOT use the machine with a non-earthed electrical supply. Do NOT use the machine with an

extension cord that is not properly earthed. If there is any doubt regards proper earthing of the electrical

supply, have a qualified electrician inspect and verify it. • If the GFCI green indicator light does not switch off

when TEST is pushed, do not use the machine until it is properly tested and repaired. • If the appliance does

not start, or stops while running, or if you experience an electric shock, switch the machine OFF and

disconnect it from the electrical supply immediately. Do NOT use the machine until it is properly tested and

repaired. • The electrical cable is not protected by the GFCI device from the GFCI device to the electrical

cable plug.

The tool is equipped with a ground fault circuit interrupter (GFCI), which reduces

the risk of electric shock. Check that the electrical mains socket that the machine

is connected to is properly grounded and test the GFCI before each use. To test:

•Connect the machine into a grounded 240VAC electrical outlet and switch

the power ON.

•Press the TEST button on the GFCI – the green indicator light should switch

off and power to the appliance should cut off.

•To restore power after testing, push the RESET button.

If the GFCI is tripped due to an earth leakage situation, the power is cut to the

machine, the green indicator lamp switches off and the red warning lamp

illuminates. Switch the machine OFF and disconnect it from the electrical supply immediately. Do NOT use

the machine until it is properly tested and repaired.

Extension Leads

When using an extension lead, ensure it is a 3-wire (grounded) type with wiring of sufficient gauge. The

usage of a smaller gauge wire could lead to excessive overheating of the motor and the cable.

Extension Cord Length (Metres)

10 20 >30

AWG 14 AWG 12 Not recommended

Tool Set-Up

Place the motor switch in the "OFF" position and disconnect the machine from the electrical

supply before assembling or making any adjustments to the tool. • Do NOT operate the

equipment with any safety device removed. • Use appropriate personal protective equipment while handling

and using the equipment. • Before use, check for broken, worn, missing, misaligned or binding parts, cable

wear or damage, or any other condition which may prevent safe and normal operation and remedy them

before operating the machine.

The tool is designed for wet drilling into concrete and stone using diamond core bits.

1. Check the appliance and cutting tools for wear or damage. If necessary, replace worn or damaged parts

before using the machine. Dull or damaged cutting tools can lead to binding, breakage, slower cutting

and increased wear and stresses to the tool.

2. Test the GFCI.

Water Connections

The water pressure should not exceed 3 bar (43PSI). • Always

ensure that the tool is operated with sufficient water supply, as

the seals can be damaged if run dry. This could lead to leakage of water into

the gearbox housing – if you detect any water leaking from the gearbox, do

NOT use the tool until it is inspected / repaired at an authorised service centre.

• When drilling "over-head", use appropriate methods and precautions for water

collection to prevent the tool from getting wet.

The tool is equipped with a water supply connection for cooling and lubricating

the drill bit. The water supply is equipped with a connector for hose coupling.

Connect the tool to a suitable water supply or pressurised vessel. Use the tap

lever regulate the water flow rate.

Fastening the Base

It is essential to secure the tool base to the work

surface to help prevent injury and to protect the

tool. An unsecured tool could rotate during drilling, cause the bit to

chatter against the work surface or bind in the hole, which can

fracture the diamond segments.

Use either a ½" or 5/8" masonry anchor to secure the tool base to

the work surface. Always be sure to level the tool base using the

adjustment bolts at each corner of the base so the drill bit contacts

the work-piece squarely and cuts straight.

Insert the securing bolt through the slot in the base and tighten the

bolt firmly.

Overload Protection

The tool is equipped with electronic overload protection, designed to protect the operator, motor and drill bit.

In the event of overload due to excessive forces or strain on the motor, the motor will be automatically

switched off. Allow the motor to cool before using the tool again.

Drilling Guidelines

•Adjust the flow of water to fully flush material from the bore hole.

•If "mud" is depositing around the bore hole, increase the water flow.

•Ensure the drill bit is securely attached and the base is set-up correctly to drill straight and prevent

vibration.

•Use sufficient pressure to cause the drill bit to cut efficiently, without placing undue stresses on the tool.

If the tool is slowing noticeably, reduce pressure.

•If the drill bit gets jammed, do not try to release it by switching the tool ON and OFF. Switch the tool OFF

immediately and remove the drill bit using an appropriate spanner. Pull the bit from the hole with caution.

Deep Drilling

When drilling holes that are deeper than the drill bit, follow the steps below:

1. Drill the hole as normal until you have drilled to maximum depth.

2. Break off the core by driving a chisel or slender wedge into the circular kerf. Remove the core using core

tongs, wire or anchor bolts.

3. After removing the core, carefully insert the bit into the hole, attach a bit extension to the bit, then

continue drilling as normal.

Drill Bits

•Drill bits with a 1-1/4” UNC female thread can be screwed directly to the tool

spindle.

•Always use drill bits that are appropriate for the material you will be drilling.

You can extend the life of the tool by using drill bits that are not damaged or

deformed. Ensure that enough diamond is exposed in every segment of the

drill bit in order to make the drilling more effective.

•The drill bit has a right-hand thread. Use a suitable spanner to hold the spindle

in place.

•Never hit the drill bit in order to remove it as the drill bit or tool may be

damaged.

•It is recommended to use grease the drill bit thread to make bit removal

easier.

Maintenance

Procedures not specifically explained in this manual must be performed by qualified

technicians only . • Before performing any inspection, maintenance, or cleaning

procedure, place the motor switch in the "OFF" position and disconnect the machine from the electrical

supply. • Do NOT allow water to get into the motor or any other electrical components. • Do NOT use

damaged or malfunctioning equipment. If abnormal noise or vibration occurs, have the problem corrected

before further use.

Follow the steps below to maintain your machine in good working order.

•Clean the tool after every use. Make sure that the ventilation slots are clean and free of any obstructions.

Do not clean using abrasives, flammable materials or harsh chemicals. Make sure that water does not

get into the motor during the cleaning process.

•Grease the drill bit thread on a regular basis.

•After 200 hours of operation, replace the motor carbon brushes.

•Keep the electrical cable, GFCI device and plug in good condition.

Motor Brushes

The electric motor uses 2 carbon "brushes" in order to function. The brushes wear as a result of use – this is

normal, and some tools may come with replacement brushes. If the brushes are allowed to wear past the

acceptable limit, the motor may produce less power, operate intermittently, or not operate at all. To check

brushes:

1. Use a coin or wide flat blade screwdriver to remove the brush cap (A).

2. Pull the brush (B) from the cavity and check the length of the carbon section (the "brush") (C). If the

brush is close to being fully worn, replace the brush – always replace both brushes at the same time.

3. Insert the brush into the cavity – the brush has 2 prongs on the electrical conductor (D) – ensure these

sit in the slots (E).

4. Re-install the brush cap (rotate right. Do not over-tighten).
