Special Safety for Coring
1.
Keep the work area dry. The Coring Motor requires the use of water. Since the use of electrical equipment in wet areas is hazardous, the equipment
must be grounded. Wear insulated footwear and gloves for extra protection against shock hazards.
2.
When coring through floors, cores generally drop from the bit. Provide proper protection for people and property below the coring area.
Sound and Vibration Information
•
Typically the A-weighted sound pressure level of the tool is less than 90 dB (A). The noise level when working can exceed 103 dB (A).
Wear ear protection!
•
The typical weighted acceleration is 2.9 m/s
These declared values were obtained by laboratory type testing in compliance with the stated standards and are not adequate for use in risk
assessments. Values measured in individual work places may be higher than the declared values. The actual exposure values and risk of harm
experienced by an individual user are unique and depend upon the way the user works, the workpiece and the workstation design, as well as upon
the exposure time and the physical condition of the user.
We, Milwaukee Electric Tool Corp., cannot be held liable for the consequences of using the declared values, instead of values reflecting the actual
exposure, in an individual risk assessment in a work place situation over which we have no control.
Functional Description of Features
(See chart for specifications on your Coring Motor)
Clutch Models
Select Coring Motors feature a friction clutch to protect the motor and
gears. If the motor overloads, the clutch will begin to slip and the bit will
stop rotating. The clutch is factory-set and does not require adjustment.
Nuisance (frequent) clutch slippage should be addressed by an autho-
rized MILWAUKEE service center. Contact the manufacturer if you have
questions about the clutch.
Shear Pin Models
Select Coring Motors feature a shear pin (B5) to protect the gears and
motor against overload. This pin drives the spindle sleeve. If the bit
binds, the pin will shear to prevent gear and motor damage. Extra shear
pins are supplied with the Coring Motor. It is important to check the
condition of the spindle before using the tool each time. The spindle must
be smooth without grooves or pitting. If the spindle is not in good condi-
tion, it is possible for the threaded spindle sleeve and the internal spindle
to weld together and lock during coring.
Soft-Start
The control box (F7) provides a soft-start feature. The Coring Motor will
smoothly reach full speed within 1-2 seconds when switched on. The
soft-start feature helps to minimize line fuse failure and jolting starts.
Residual Current Device (E13)
Select Coring Motors are equipped with a Residual Current Device (RCD),
which is a protective device that shuts off the power supply if there is a
mains voltage failure or faulty electrical current. Coring Motors that are
equipped with an RCD must always be used with the RCD installed.
12H Plug (E14)
Select Coring Motors are equipped with an IEC 309 specified 12H plug.
These specifications are recognized world wide and are intended to pre-
vent the mating of plugs and receptacles of different voltage and amper-
age ratings. The ground sleeve is positioned at a specific hour point,
depending on the device's voltage rating. The plug ground pin location is
a mirror image of the receptacle. In addition, voltage ratings for all IEC
309 plugs and receptacles are color coded for visual identification.
The MILWAUKEE Coring Motors with IEC 309 plug use a 12H configura-
tion which signifies that with the keyway located in the 6 o'clock position,
the ground pin is at the 12 o'clock position. The voltage rating of the 12H
configuration is 125/250 VAC. This configuration is for use with an iso-
lated mains supply, usually an isolation transformer.

Assembly
Coring Motors must be attached to a stand
Follow the specific instructions packed with the stand. Use the mounting
holes (A1) in the back of the Coring Motor to mount it to the stand.
Mounting the control box
The control box can be mounted to the top of the coring stand or to the
Coring Motor.
Mounting the control box to the top of the coring stand
Use a strap (C6) to attach the control box (C7) to the top of the coring
stand (C8). Make sure that the lip (C9) on the top of the control box rests
on top of the coring stand.

Remove one brush holder cover (D10) by removing the screw (D11) at
the top of the cover. Save the brush holder cover for later use.
Attach the control box (D7) to the motor housing (D12) with the screw
from the brush holder cover.
Remove the water shut off valve components from the accessory bag.
The copper washers in the accessory bag are for bit mounting.
Thread the shut-off valve assembly (A3) into the spindle sleeve on the
Coring Motor. Hand-tighten the assembly and then tighten it approxi-
mately 1/4 turn with an adjustable wrench (not provided).
Attach a water supply to the water shut-off valve.
WARNING!
To mount a bit, grease the spindle (A2) and bit threads to prevent
corrosion and to help prevent the bit from locking on the spindle.
Slip one copper washer (provided in separate accessory bag with the
water shut-off valve components) onto the spindle against the spindle
shoulder. The bag should contain an extra copper washer; save it for
future use.
Thread the bit securely onto the spindle.
