Hole Start Mode
Use the Hole Start Mode to help avoid bit jamming or
bit binding when starting a hole. Hole Start Mode will
run until the bit is "seated" into the material, then it
will automatically turn off and the drilling will continue
in the selected gear.
Activating the Hole Start Mode:
1. With the machine armed, turn on the spindle by
switching to the ON position.
2. Press the
button, to start the Hole Start
mode.
Deactivating the Hole Start Mode:
1. To turn off the machine, press to the OFF position.
2. Unarm the machine.
Digital Level
Use the digital level to ensure the hole
is level throughout the operation. Use
the digital level to properly align the core
drill when installing into a core drill
stand. The four red arrow LEDs indicate
where the machine is off of level and the
direction in which the machine needs to
be moved to become level. Check eye-
bolts, vacuum pad, and anchor when
leveling. The center white LED indicates
the machine is level.
• When level, the center White LED will
light up (<1.5° off of level).
• When "slightly" off level, the center White LED and
the Red LED associated with the direction that is
off center.
• When "very" off level, the red LED will show the
direction out of level and will illuminate (>2.7° out
of level).
NOTE: The digital level will flash four red arrow LEDs
and a white center LED in an alternating pattern if the
machine is unable to provide a level. If this occurs,
the machine will still operate upon normal cycling of
the switch. In order to restart the digital level, the ma-
chine will need to be disarmed and re-armed again.
If the machine still does not work properly, return the
machine, charger and battery pack, to a MILWAUKEE
service facility for repairs.
Performance Indicator
The performance indicator
provides pressure feedback.
The LEDs will light up one by
one as pressure is applied to
the bit. Increase or decrease
pressure on the bit to reach
the green "Ideal Pressure".
When using new diamond
bits, follow manufacturer's
instructions for breaking them
in (see "Diamond Core Bits").
After the bits have been
broken in, low feed pressure
will polish diamonds, slows
penetration and contributes to bit glazing. High feed
pressure can overload the core drill motor or can
cause diamonds to pull out prematurely, particularly
when coring embedded steel. Make the bit work, but
do not try to jam the bit through the material.
