1.2 SAFETY PRECAUTIONS
DANGER!!!
The following instructions are essential safety measures that you must take.
Unless observed, improper way of use leads to death or serious injury of yourselves or others.
[1] Know your machine. Read this manual carefully to learn the application of the machine and the limitations as
well as potential hazards associated with the machine.
[2] During the operation, the Core-Bit rotates with very high speed. Do not wear loose clothing, dangling objects,
rings, and jewelry to eliminate the risk in which the operator gets caught in the moving parts such as the
Core-Bit. Keep your face away from the air inlet, outlet of the motor. Long hair must be tied up.
[3] Always wear protective clothing such as helmets, safety goggles, earplugs, heavy-duty gloves, and special
work boots with reinforced toe. (During the operation, do not wear gloves to reduce the risk in which the
operator gets caught with the Core-Bit.)
Max. Noise Level of this machine is 84.0(A).
[4] Do not operate when you are tired or under the influence of any medicine, drugs, and alcoholic beverages.
[5] Consider the work area environment. Do not expose the drill motor to water. Water in the drill motor increases
the risk of electric shock.
[6] Do not operate the machine in the presence of flammable liquids or explosive or combustible gas. Sparks
generated byArmature and Carbon Brushes in the Drill Motor could cause an explosion of fire.
[7] In case of operation in a closed room or basement, make sure that the air is in good condition (plenty of oxygen,
no toxic gas), before operation.
[8] Before operation, do ensure that the Core-Bit is connected with the Spindle of the Drill Motor tightly and
securely, so that the Core-Bit will not come off and not cause damage to persons and property around.

5
SAFETY
[9] Before operation, do ensure that the Drill Stand is fixed firmly to the surface of drilling object.
[10] Never use this machine without the Portable Residual Current Device (PRCD), which is equipped in the electric
cable. And inspect it periodically to confirm that it works properly.
[11] Before starting drilling, make sure that there is no live electric cable in the drilling object that the Core-Bit will cut
through.
[12] Do not allow other persons to use this machine, unless they have read and understand this manual.
[13] Unintentional start of the Drill Motor is quite dangerous. When the Drill Motor is not in use with the drilling
operation, do ensure that the switch is in the “OFF” position, and that the plug is disconnected from the power
source outlet.
[14] If the main power supply gets power failure during operation, turn off the switch immediately in order to avoid
the unintentional start of the Drill Motor.
[15] When drilling at high level, keep proper footings and balance at all times. Maintain a firm grip, in order not to
drop the machine. Use extra care when you are on ladders, roofs, scaffolds, …etc.
[16] When drilling through floors, the core will be likely to fall down from inside of the Core-Bit. Under these
circumstances, provide proper protections for people and property below the coring area. For example, fencing
around the particular area down floor, making the place “KEEP OFF” …etc.
[17] Never yank the cord to disconnect it from the socket. Keep the cord away from heat, oil and sharp edges.
[18] Plug is essential for safety. Never connect directly to distribution board without using a plug for fixed
installation.
[19] This machine must not be used for drilling upwards for electrical reasons. When drilling horizontally on the wall,
water collection device must be used.
[20] All the services, with the exception of maintenance written in this manual, must be carried out by authorized
service center.
[21] Always compare the voltage value on your Core Drill with your proper supply source. The power supply source
should not vary more than 10% from the voltage figure shown on the nameplate.
[22] Do not operate the machine alone. Make sure you can contact someone in the event of accident.
[23] Do not allow anyone near the machine when starting or operating. Keep bystanders away from the machine
and cable.
[24] Use common sense and plan your work to avoid injuries. Your own safety as well as the safety of your fellow
worker depends on your carefulness and good judgment during the operation.
[25] Avoid body contact with earthed or grounded surfaces (e.g. pipes, radiators, ranges, refrigerators).
[26] The use of any accessory or attachment other than one recommended in this instruction manual may present a
risk of personal injury.

SAFETY
1.3 IMPORTANT OPERATING INSTRUCTIONS
WARNING!!
Following instructions are essential measures that the operators must take.
[1] Ensure that the adequate water is supplied to the Core-Bit during operation, unless Dry-Bit is used. Do not
allow excessive heat to be generated at segments of the Core-Bit. The overheat may result in breakage of the
segments, and may lead to injury of the operator.
[2] Do not block the cooling air inlets of the Drill Motor. If the inlets are blocked, the cooling might be insufficient
and the Drill Motor could burn.
[3] Do not let water get into the Drill Motor. The water in the motor can decrease the insulation capacity and the
Drill Motor could burn out. Also, do not expose the Drill Motor to rain or snow.
[4] Do not push the Core-Bit too hard. Too much pressure on the Core-Bit will decrease the drilling capacity and
might burn the Drill Motor.
[5] Before start drilling, make sure the Carriage Block (Feed House) is properly adjusted and that the tool is in line
with the Drill Stand. When you adjust it, make sure the plug is disconnected from the main power source.
[6] Check for damaged parts. Inspect guards and other parts before use. Check for misalignment, binding of
moving parts, improper mounting, broken parts, and any other conditions that may affect operation. If abnormal
noise or vibration occurs, turn off the machine immediately and have the problem corrected before further use.
Do not use a damaged machine as it is. Tag damaged machine “DO NOT USE” until repaired.
[7] Maintain tools carefully. Keep handles dry, clean, and fee from oil and grease. Keep cutting edges sharp and
clean. Follow instructions for lubricating and changing accessories. Periodically inspect the machine’s cord for
damage. Have damaged parts repaired or replaced by authorized service center.
[8] When not in use, store the machine in a dry secured place. Keep out of reach of children.

GROUNDING INSTRUCTION
4.0 GROUNDING INSTRUCTION
This machine must be connected to a properly grounded outlet. If the tool should electrically malfunction or breakdown,
grounding provides a low resistance path to carry electricity away from the operator, reducing the risk of an electric
shock.
WARNING!!
Improper connection of the grounding wire can result in the risk of an electric shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not
modify the plug provided with the machine. If the cord or plug is damaged, have it repaired by a Shibuya’s
authorized service center, before use. If the plug will not fit the outlet, have a proper outlet installed by a
qualified electrician.
RESIDUAL CURRENT DEVICE (RCD)
5.0 RESIDUAL CURRENT DEVICE (RCD)
According to the European standards EN61029-1 and IEC 1029-2-6, the electrical connection of diamond core drills with
water supply must be operated via a residual current device (RCD or PRCD).
DANGER!!!
Note that you have a potential hazard that the drill may cut a live electric cable hidden in the drilling object. To
reduce shock hazards, use Residual Current Device (RCD), or Ground Fault Circuit Interrupter (GFCI), or
Insulation Transformer. Connection to main power supply must be made using one of these devices.

FEATURE OF THIS MACHINE
6.0 FEATURE OF THIS MACHINE
[1] Circuit Protector (Switch)
This machine is equipped with a Circuit Protector to reduce the risk of damage of the Drill Motor. The Circuit
Protector trips when the Drill Motor is overloaded. Too much feeding pressure will cause the Circuit Protector to trip
frequently. And frequent trip may lead to damage on the Drill Motor. Try to operate so as not to make the Circuit
Protector trip. CAUTION!
Do not fit any Circuit Protector of wrong specification that may cause damage of the Drill Motor. Use only
Circuit Protector of Shibuya’s genuine spare parts. Regarding the specification of the Circuit Protector, refer to
the spare parts list attached in the end of this manual.
[2] Clutch System
This machine has an Inner Clutch System to protect gear parts. If Core-Bit is suddenly jammed due to the
presence of piece of iron or similar materials, Spindle and gear parts are subject to severe shock. The Clutch
System plays an important role in such situations by relieving the shock. The Clutch System only operates if the
gear parts are subject to potentially damaging shock.
10
CAUTION!
The long time operation or operation at heavy-duty construction site would make the Clutch System loose. If
so, have it repaired by Shibuya’s authorized service center. Do not try to tighten it by yourself.
[3] Swivel Ring
This machine has a Swivel Ring for feed water. This makes it possible to feed water from any angle.

9.7 REPLACEMENT OF O-RING
When O-Ring inside Swivel Ring is worn out, water would be leaked from the
Swivel Ring.
W
e recommend replace O-Ring with new one, when Oil Seal is changed.
9.8 REPLACEMENT OF SEAL RING
There is a Seal Ring between Spindle and Oil Seal. The Seal Ring is not visible from outside. However, we recommend
ou change Seal Ring as well as the Oil Seal, if the Seal Ring is worn.

9.9 LUBRICATION
[1] Lubrication for reduction gears of the drill motor
Inject a small quantity of grease simultaneously when replacement of consumption parts such as Carbon Brushes
and Oil Seal are made.
Use Shibuya’s genuine grease (Optional item).
The equivalent grease is MOBILUX EP1, Lithium type No. 1 Grade.
How to inject the grease is explained as follows;
1) Unscrew a Hex. Socket Plug of Grease Inlet with Allen Key (5mm) (Optional Item)
Inject approx. 2cc of the grease from the inlet.
2) Tighten the Hex. Socket Plug to cover the inlet Grease Inlet
NOTE
[2] Lubrication on the thread of the Spindle
Low viscosity type grease is used for this machine. As the grease lasts long comparatively, it should basically
be sufficient to replenish the grease when Carbon Brushes and Oil Seal are replaced. If the grease is
replenished very often, the Gear Case will be full of the grease and it could make extra friction to reduce the
drilling performance.
Lubricate the thread of the Spindle with some grease and then attach the Core-Bit.
The lubricant on the thread makes the detachment of the Core-Bit easier after drilling.
[3] Lubrication on the Column and Leveling Bolts
Put some spray-oil to the Column and Leveling Bolts.
