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.

General Cont:
Exposure to dust, gases and fumes
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
awkward or static working
positions repeated or maintained
for long periods; holding handheld
equipment over extended periods;
and lifting, pushing, levering,
holding or carrying plant,
equipment and cut sections of
concrete and materials.
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.

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
eye bolt so that an appropriate lifting device
can be used to move the core

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

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.

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.
DO NOT operate in areas where flammable
gases/vapours are present unless the unit is
intrinsically safe to do so.
Pull plug prior to cleaning. Clean motor by
means of dry compressed air (from the
outside). Check connecting lines on damages

Ensure the power pack is far enough away from combustible materials and there is adequate ventilation for the removal of exhaust gases. Ensure that the tool being connected to the power pack has a compatible flow and pressure rating. Danger - Never use tools that are incompatible with the power pack. Do not alter the engine speed as increasing it will affect the outlet flow and pressure rendering the power pack dangerous to use. Check hydraulic hoses and connectors daily for wear and leakages. Replace as necessary When refuelling: • Always handle petrol with care; it is
highly flammable. • Store petrol in containers specifically
designed for this purpose. • Always refuel outdoors where there are
no sparks and flames. Do not inhale petrol vapours. Do not smoke while refuelling or handling fuel.
• Keep petrol away from the eyes and
skin. If petrol comes in contact with the eyes, wash them immediately with clean water. If irritation is still present, see a doctor immediately.
• Clean up spilled petrol immediately.

Before you start changing the drill bit, make sure that the machine is disconnected from compressed air supply, in order to avoid unintentionally starting of the machine and to prevent injuries. Fix the machine onto the appropriate drilling device (foot-mounting). Manually screw the drill bit onto the drill bit adapter. Manual tightening is sufficient because the drill bit will automatically fasten during drilling operation. If necessary, to attain an angled drill hole, adjust the stand position by swivelling the arm of the stand. Connect the machine to the water supply. Finally connect the machine to the compressed air supply. Actuate air valve trigger to switch on the motor and to start the drilling.
