TROUBLESHOOTING
Vibration
1. Stop drilling.
2. Turn core drill o
ff .
3. Remove battery.
4. Check for loose nuts and bolts. Tighten if required.
5. Check for excessive core drill bit runout. Replace if
required. If vibration continues to occur, remove the core
and loose material. If vibration continues to occur after
attempting these measures, return the rig to the nearest
MILWAUKEE service facility.
Core drill bit Binding
Core drill bit binding is caused by one of two things: a dull
(glazed) core drill bit or a poorly stabilized stand.
Causes of core drill bit glazing:
• Wrong RPM for core drill bit diameter
• High feed pressure
• Low feed pressure
• High steel content in work surface
• Large, hard aggregate
• Too much water
• Low motor power
A sharp core drill bit typically has good diamond exposure and
will cut/grind almost anything in its path, including embedded
steel.
MAINTENANCE
The ventilation slots of the machine must be kept clear at all
times.
Use only Milwaukee accessories and spare parts. Should
components need to be replaced which have not been
described, please contact one of our Milwaukee service
agents (see our list of guarantee/service addresses).
If needed, an exploded view of the tool can be ordered.
Please state the Article No. as well as the machine type
printed on the label and order the drawing at your local service
agents or directly at: Techtronic Industries GmbH,
Max-Eyth-Straße 10, 71364 Winnenden, Germany.

After the core drill bits have been broken in, low feed pressure
will polish diamonds, slows penetration and contributes to core
drill 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 core drill
bit work, but do not try to jam the core drill bit through the
material.
Fuel Gauge
When the machine is armed, the fuel gauge displays the
battery pack's remaining run time. The fuel gauge mirrors the
fuel gauge on the battery pack. When less than 10% of charge
is left, one light on the fuel gauge will fl ash 4 times. When the
battery reaches 0% charge, the fuel gauge will fl ash 8 times.
Charge the battery pack.

WATER CONNECTION
A water connection is available on the tool to cool the core drill
bit and reduce the formation of dust. The water connection
should be used on all concrete cutting applications.
For best results, allow the water to coat the entire cutting
wheel before operation.
ONE-KEY™

con fi gured via the ONE-KEY™ app.
Blinking Blue Tool is actively communicating with the
ONE-KEY™ app.
Blinking Red Tool is in security lockout and can be
unlocked by the owner via the ONE-KEY™
app.
BATTERIES
Battery packs which have not been used for some time should
be recharged before use.
Temperatures in excess of 50°C (122°F) reduce the
performance of the battery pack. Avoid extended exposure to
heat or sunshine (risk of overheating).
The contacts of chargers and battery packs must be kept
clean.
For an optimum life-time, the battery packs have to be fully
charged, after used.
To obtain the longest possible battery life remove the battery
pack from the charger once it is fully charged.
For battery pack storage longer than 30 days:
Store the battery pack where the temperature is below 27°C
and away from moisture
Store the battery packs in a 30% - 50% charged condition
Every six months of storage, charge the pack as normal.
BATTERY PACK PROTECTION LI-ION BATTERY
The battery pack has overload protection that protects it from
being overloaded and helps to ensure long life.
Under extreme stress the battery electronics switch o ff the
machine automatically. To restart, switch the machine o ff and
then on again. If the machine does not start up again, the
battery pack may have discharged completely. In this case it
must be recharged in the battery charger.
TRANSPORTING LITHIUM BATTERIES
Lithium-ion batteries are subject to the Dangerous Goods
Legislation requirements.
Transportation of those batteries has to be done in accordance
with local, national and international provisions and
regulations.
• The user can transport the batteries by road without further
requirements.
• Commercial transport of Lithium-Ion batteries by third parties
is subject to Dangerous Goods regulations. Transport
preparation and transport are exclusively to be carried out
by appropriately trained persons and the process has to be
accompanied by corresponding experts.
When transporting batteries:
• Ensure that battery contact terminals are protected and
insulated to prevent short circuit.
• Ensure that battery pack is secured against movement
within packaging.
• Do not transport batteries that are cracked or leak.
Check with forwarding company for further advice
WORKING INSTRUCTIONS
To gain a better drill progress take out the centre core drill bit
after having reached a depth of about 10-15 mm. Insert core
cutter into the existing groove and let machine run up
smoothly.
Bore-holes which don't have to be applied exactly can be
drilled without a centre core drill bit. For that purpose apply the
core cutter slantingly and put the machine slowly straight
when a depth of about 5 mm has been reached. (This is only
possible when using short core cutters!)
If drill cores should come loose, take core cutter from the
material and remove drill cores.
For best performance the diamond segments should be
"roughed-up" to expose the fragments of diamond: To expose
the diamond fragments rub surface of segments with stone
