SUMMARY SAFETY REQUIREMENTS (Provide a summary of the main safety requirements identified in the SWMS – this should be done following completion of the SWMS)

• Core Drilling Machine is made to drill holes in granite, masonry and steel reinforced concrete. Follow instructions on proper use of this machine. Do not use for other purposes.

• Do not wear loose cloth gloves or loose clothing when operating machine. Wear only leather gloves. Keep sleeves and jackets buttoned.

• Do not reach across the machine or drill bit. Clothing can be caught by the machine resulting in entanglement and serious injury.

• Use extreme caution when drilling through floors. Provide protection of all personnel and material below the area. Cores generally drop from the drill at completion of the hole.

• When required ensure barricades, signage and spotter is in place.

• Keep fingers and hands away from drill bit. This practice will prevent entanglement and reduces risk of being cut.

• Secure drill stand to the work surface. Use bolts, ceiling jack or vacuum hold-down.

• Drill stand must be properly secured to prevent bit damage and serious injury.

• When releasing carriage locking handle, maintain a firm grip on feed handle to prevent feed handle from revolving due to weight of drill. Rotating handle can result in injury.

• Do not force drill bit. Drill should be used at a speed and feed rate based on the manufacturers specifications. • When starting bits, do not use more than two 30cm extensions. Less likely to bind and lose control.

hands.


5 Secure the Core Drilling Machine by one of the following methods –

5A Bolt Anchor Method-to-Floor

Drilling machine not secured

properly to work surface may cause

serious injury to the operator

Mechanical anchor could pull out

causing damage equipment and to

client assets.

Striking injuries from dislodged

equipment

Movement during drilling will cause

chatter of bit against work surface,

fracturing diamonds.

Bit may also bind in hole causing

damage to the bit.

3 D E4

Measure distance from centre of anchor bolt

slot in base to centre of drill spindle.

To locate the anchor bolt hole, use the

distance obtained above and measure from

the centre of the hole that is to be drilled.

Drill and set mechanical anchor. Place Drilling

Machine over anchor hole and hand tighten

anchor bolt.

Adjust the 4 levelling screws to stabilize base

and plumb mast. Secure machine by

tightening anchor bolt. Never hit the base

with a metal hammer to position it.

Ensure sufficient water is used to flush the

core bit during core drilling operations.

Locate if possible any reinforcing bar to avoid

splitting bar causing steel slither


5B Bolt Anchor Method-to-Wall As above 3 D E4

Use the same bolt anchor method procedure

to anchor as above.

Ensure the mechanical anchor is rated to the

capacity required for the task

When anchoring to a brick or masonry wall

use an epoxy anchoring system or through

bolt anchors with appropriate backing plates

damage to the bit.

Operators using a vacuum assembly

to anchor a core drill stand to a

surface may risk injury if the

vacuum pump fills with slurry. This

can cause loss of vacuum, which

can result in the drill stand breaking

free and rotating round the drill

causing striking and crush injuries.

Collapse of unit due to power

failure or interruption

3 D E4

The Vacuum Anchor Method is only

recommended for 20 cm diameter holes or

less.

The Anchor Vacuum Method is NOT

recommended on rough or cracked floor

conditions, holes deeper than one bit length

or steel concentration greater than standard

rebar.

Also fasten a chain to the Core Drilling

Machine and secure the chain to prevent the

machine falling and causing serious injury.

Step1 Turn machine on its back and insert vacuum

seal under machine base, inspecting first to

ensure seal is in good condition and sealing

groove is clean.

Step 2 Turn Drilling Machine up-right and loosen 4

base levelling screws.

Step 3 Plug power cord into a properly grounded

receptacle and turn vacuum pump ON/OFF

switch to the ON position.

Step 4 Insert vacuum slot cap into anchor bolt slot

and check vacuum and hose connections.

Ensure vacuum gauge pressure is consistent

with the manufacturers specifications

Step 5 The drilling machine should now be vacuum

anchored. If machine does not anchor, add

weight by standing on vacuum base.

Step 6 Check the floor and vacuum seal for leaks

Step 7 Frequently check the water level in the

vacuum water trap. When water trap

becomes half full, stop drilling and empty

water.

Step 8

After using, turn drill motor ON/OFF switch to

the OFF position, then turn vacuum motor

ON/OFF switch to the OFF position, unplug

power cord and remove, clean and store

vacuum seal

Where there is the possibility of loss pressure

operators shall use bolt down stands where

practical. If a vacuum attachment must be

used, ensure you monitor the equipment to

ensure that vacuum pressure is maintained.

When a vacuum system is used to secure a

drill stand to concrete, the compressor must

have a receiver tank to ensure the operator

has time to take action (if power is cut to the

compressor) before the drill loses its hold

3 D E4

Once base is secured mount drill carriage and

bit in accordance with manufacturer’s

instructions.

Identify the type of core drill bits for example

Gap or open ended

Gap core bits have a built in spindle adapter

which makes it easier to attach and align.

Open ended are more cost effective and

easier to get a large core out

Open ended core bit require an expansion

adapter that locks onto the open end

To prevent equipment damage never use a

pipe wrench to tighten the adapter onto the

spindle

Never turn the bit on when it is resting on

concrete

Ensure setup is performed in module format

from the drilling process - Dry

cutting of bricks and concrete with

diamond tipped blades is known to

produce very high levels of silica dust. Musculoskeletal injuries from









Vibration transmitted from drilling

equipment can affect the operator’s

whole body or parts of the body,

such as the hands and arms.

Pooled water in a workplace (such

as coolant water used in concrete

drilling), increases the risk of

electrocution.

The risk of injury or harm may

increase when an operator is

working alone because of

difficulties in setting up and

relocating equipment on site, the

nature of the work and the absence

of a back-up person should an

emergency arise.

3 D E4

Before turning drill motor ON, be certain that

machine is securely anchored- recheck

mechanical anchor and ensure mounting legs

are tight and secure.

With the bit off the surface turn on the drill to

keep the bit from chattering keep the

downward pressure light to commence with

Do not increase the downward pressure until

the bit crown has penetrated the material

Drill bit feed should be uniform without

excessive force. Drilling penetration of 2.5 cm

to 10 cm per minute may be achieved in

concrete depending on material and bit

diameter.

Ensure feed pressure of the core drill system

does not exceed safety overloads.

Proper feed pressure is determined by load on

motor. Accordingly, be aware of the

armature load of the motor. Excessive load

will reduce the armature life reducing drill

speed and damage to segments

NOTE! If the cooling water turns clear, it is an

indication you are drilling through rebar.

When encountering rebar it is recommended

you reduce RPM until the rebar is cut

NOTE! An operator may be considered to be

working alone when they cannot be seen or

heard by another person, and cannot expect

a visit from a supervisor, another worker or a

member of the public for some time.

Person Responsible


General Cont: As above 3 D E4

NOTE! It is recommended that after cutting

steel, you stop and break out core and any

loose pieces of steel, before proceeding.

Where water is pooling during the drilling

process It should be removed with a wet and

dry vacuum cleaner before any electrical

equipment is used in the area.

Extension leads, plugs and electric powered

tools must be kept away from dry cutting

equipment, or drilling water or slurry that

cannot be easily removed.

Ensure appropriate communication and first

aid facilities are available where people

3 D E4

When drilling holes in excess of 500 mm

diameter it is advisable to use multiple

anchor points and a back brace the drill

column. The back brace should be set at

approaching 45 degrees.

For large or deep holes set two anchors as

wide apart as the drill base anchor slots will

allow. Use 19 mm anchor bolts for holes over

50 cm in diameter

Take appropriate steps to prevent heavy

cares from falling or damaging the drill bit

3 D E4

Extension rods will allow for the drilling

deeper holes than the length of the bit- drill

rates will slow with the full length of the bit in

the hole

When you have drilled to the full depth of the

bit, back the drill out and remove the core,

put the bit back into the hole and connect the

extension to the bit and tighten with a bit

wrench. Screw the extension rod onto the

drill spindle and secure it with a spindle

wrench. Refer Part 11. Outer diameter of the

segment.

When undertaking horizontal and angle cuts

of over 25 cm in diameter the bit and spindle

can be damaged by the weight of the core

and in some cases the care could fall causing

serious injury or damage.

To protect the bit and allow safe core

removal stop drilling 6 mm to 19 mm of going

all the way through. Remove the bit and

stabilise the core if necessary – Use wedges

or a bar in the curves to break the core free.

When unsure of wall thickness – rod or

hammer a small probe hole into the area and

measure the thickness then plug the hole to

prevent water and slurry damage and

running through the hole.

Alternatively use a depth indicating device to

determine thickness

To remove a heavy core insert a anchor and

NOTE: Where possible only use a hydraulic

core drill – do not use an electrical core drill

that is not certified for inverted core drilling

Inverted drilling may be accomplished by

using a tall floor mounted column base if the

ceiling is not over 300 cm high

When drilling large diameter holes overhead

the core should be supported from above.

Always refer to the table of Core Weights and

proceed accordingly. Refer CSDA Technical

Manual for further guidance

Be aware that when commencing to drill the

segments may be dry during the initial start

up period.

Do not remove the rotating bit from the hole

as the water and core can throw it out of

balance and damage the drill and bit. Stop

the drill, disconnect the water and allow the

bit to drain. If you are lowering the core bit

and drill yourself position yourself properly to

support the weight before unscrewing the bit

from the motor.

If a core drill must be anchored to a ceiling,

always install two anchors if drilling a hole

larger than 15 cm in diameter. Never trust a

carriage lock screw to keep the drill from

sliding down on the column

3 D E4

Always wear the protective clothing and

equipment as highlight in this SWMS

NOTE! The outside of the core drill itself

might be over 30°C warmer than the ambient

air temperature. So always wear protective

clothing including gloves.

Always disconnect the hydraulic circuit

before changing drill, dismounting hoses or

servicing the core drill.

Fine jets of hydraulic oil at high pressure can

penetrate the skin. Do not use your fingers to

check for hydraulic leaks. Do not put your

face close to suspected leaks. Hold a piece of

cardboard close to suspected leaks and then

inspect the cardboard for signs of hydraulic

oil. If hydraulic oil penetrates your skin, get

medical help quickly.

Never leave the core drill connected to the

power source when not in use.

Supply hoses must have a minimum working

pressure rating of 2500 psi/175 bar.

Check hoses regularly for damages and

replace if necessary. Check bolts and nuts and

clean quick-release couplings before use.

The hydraulic circuit control valve must be in

the OFF position when coupling or uncoupling

the tool. Wipe all couplers clean before

connecting. Failure to do so may result in

damage to the quick couplers and cause

overheating. Use only lint-free cloth.

Do not exceed the rated limits of the tool or

use the tool for applications beyond its design

capacity.

Connect the hoses from the hydraulic power

source to the tool fittings or quick

disconnects. It is good practice to connect the

return hose first and disconnect it last to

eliminate or reduce trapped pressure for

easier quick-connect fitting attachment.

Observe the flow indicators stamped on the

hose couplers to ensure that the flow is in the

proper direction.

Ensure critical tool markings, such as labels

and warning stickers are legible.

Always replace parts with replacement parts

recommended by the manufacturer

Good maintenance practice keeps the core

drill on the job and increases its service life.

The most important maintenance practice is

to keep the hydraulic fluid clean at all times.

Contaminated fluid causes rapid wear and/or

failure of internal parts.

10A-1 Electrical Power Supply Cont: As above 3 D E4

Take into account the location of the power

unit to keep it as close as possible to the

equipment in order to reduce pressure losses

in the line. Pressure losses from long hose

lengths can reduce the system performance

and generate significant heat.

Ensure the system is correctly earth for

example through a properly inserted ground

rod.

Use cords that are in good condition and are

rated to carry the current output from the

power source

Uncoil all leads completely – coiled leads with

the current passing through creates heat and

may cause fire or loss of power

Keep cords and connectors out of water and

protected from damage

All electrical work on the power unit should

be performed by a licensed electrician.

Ensure the intake air path to the electric

motor fan is unobstructed.

screwdriver into the drilled groove and prying

the core to the opposite side. Use a second

screwdriver to lift core out.

Removing Broken Core Below the Surface.

• Use a 3 mm diameter steel rod.

• Make 6 mm long 90° bend at one end.

• Insert rod down side of broken core to

depth of break twist 90° and lift core out

Removing Broken Core Stuck in Bit Unplug machine cord from power source and

damage to the bit.

3 C H3

In order to drill deeper than the 45 cm long

bit will allow bit extension rods must be used.

Drilling rate will be slower because of the

extra amount of drag on the bit walls.

NOTE! When it is necessary to place the

drilling machine above the surface being

drilled, do not use a bit extension rod that is

longer than 30 cm. Drill to full depth of bit. -

Back drill out and remove bit and core.

Put drill bit back into hole and connect a 10,

15 or 30 cm bit extension rod to bit and

secure with spindle wrench.

Screw bit extension rod onto drill spindle and

secure with spindle wrench.

Proceed with drilling

Inspection and maintenance of

core drilling machine

Damage and failure to equipment 3 C H3

The following inspection procedures shall be

performed on a daily basis:

• Make sure Core Drilling Machine is

unplugged and the drill mast switch is

set to the OFF position.

• Inspect the vacuum seal for wear or

damage. Replace if necessary. Vacuum

seals should be removed and cleaned

after each use as accumulated slurry will

cause them to deteriorate quicker

• Inspect the power cord and plug for

damage. If the plug has been modified,

is missing the grounding prong or if the

cord is damaged, do not use the

Machine until the cord has been

replaced.

• Lubricate the Core Drilling Machine if

necessary according to the

Manufacturers Maintenance

Instructions.

• Inspect the Core Drilling Machine for any

broken, missing, misaligned or binding

parts as well as any other conditions

which may affect the safe and normal

operation of the machine. If any of these

conditions are present, do not use the

machine until any problem has been

repaired.

Use drill bits and accessories that are

designed for the Machine and meet the needs

of your application.

• Clean any oil, grease or dirt from all

handles and controls. This reduces the

risk of injury due to a tool or control

slipping from your grip.

• Inspect the cutting edges of y our drill

bits. If necessary, have them replaced

prior to using the Core Drilling Machine.

• Bits are considered worn when the

crown shows excessive wear and has

become flush with tube. Dull or

damaged cutting tools can lead to

binding and tool breakage.

• Anchor bolts and levelling screws shall

be cleaned with a wire brush and

lubricated.

• Carriage and column shall be cleaned

and lightly lubricated.
