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 by Armature 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.
4
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.

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.
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.

Jam of Core-Bit
The Core-Bit is likely to be jammed during operation when cutting rebar thinly or if the installation of the Drill
Stand gets loose.
In that case, we recommend you use the Tool to take out bit (Optional Item) for releasing the jammed Core-Bit
easily without damaging the machine.
CAUTION!
Do not try to release the jammed Core-Bit by utilizing a starting torque of the Drill Motor. The Drill Motor is likely
to damage if it is switched on repeatedly with the Core-Bit jammed.
Do not force to pull out the jammed Core-Bit by rotating the Feed Handle, either. It may results in the damage
of the machine.

MAINTENANCE
9.6 REPLACEMENT OF OIL SEAL
When Oil Seals (Water Seals) are worn out, water would be leaked from the
small hole on the Fixing Ring.
If you find the water leakage, bring your machine to your nearest Shibuya’s
authorized dealer to have the Oil Seal replaced.
Small hole on the Fixing Ring
9.7 REPLACEMENT OF O-RING
When O-Ring inside Swivel Ring is worn out, water would be leaked from the
Swivel Ring.
We 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
you 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
[2]
NOTE
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.
Lubrication on the thread of the Spindle
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.
