NOTE: Before mounting the drill motor,

make sure that carriage lever is in such a

position that doesn’t allow the carriage with

spacer block and drill motor slide along the
track.

WARNING: Before mounting the drill motor

on the carriage make sure that the drill

motor is disconnected from electric power.

WARNING: If the track is tilted forward,
make sure that there is no risk of damaging
base plate.

WARNING: Do not over-tighten the screws
(max torque 50 Nm), as the thread can be
damaged!

6.7 Spacer block mounting

To use core bits with diameter greater than 400
mm, the distance between the drill track and the
drilling axis needs to be increased by mounting a
spacer block.
For spacer block mounting, open the motor clamp
of the carriage.
Place the spacer block on the carriage and tighten
the clamp (max torque must not exceed 40 Nm).
To mount the motor on the spacer block, open the
motor clamp of the spacer block.

6.9 Changing spindle gearbox of the drill
motor

Depending on the drill bit size, three types of spindle
gearboxes (SG15, SG30 or SG60) can be used.
To detach the gearbox unit from the motor, use a 17
mm socket. Loosen and remove the four screws on
the spindle gearbox unit. Pull the spindle gearbox
unit off the CM-10 drive unit. To mount the gearbox
on the drive unit, align the holes in the gearbox
with the holes on the unit, insert the splined drive
shaft into the motor drive unit and gently push
the gearbox unit onto the splined drive shaft of

the drive unit. Make sure that the gearbox unit
is fixed on the drive unit properly and there is no
gap between gearbox and drive unit. Tighten four
screws with a 17 mm socket wrench with torque not
to exceed 44 Nm.

NOTE: Do not tighten the spindle gearbox
screws if the gap between gearbox and
drive unit is present.

WARNING: Do not over-tighten the screws
(max torque - not to exceed 44 Nm), as the
thread can be damaged!

WARNING: Before mounting the drill motor
on the carriage make sure that the drill
motor is disconnected from electric power.

NOTE: Prior to drill motor mounting make
sure that carriage lever is in such a position
that doesn’t allow the carriage with the drill
motor slide down along the track.

6.11 Hand crank mounting

The hand crank can be mounted on the left-hand
side or the right-hand side of the carriage. On either
side, shafts provide drive of the carriage through
reduction gearing.
Instead of the manual feed crank a 1/2-Inch Wrench
Ratchet Square Drive can be used.

6.12 Water supply connection

A proper water supply is required during the wet
drilling, since the water cools the drill motor and
the core bit, and flushes the slurry created during
the cutting process off the cutting area.
Connect the water supply hose with a valve to the
hose connector on the core drilling machine.

WARNING: Use clean water only, as dirty
water may cause machine damage!

WARNING: If the drill motor gets
overheated, increase the water flow to
prevent the motor failure. The water
temperature must not exceed +40 C°

(104°F)

WARNING: minimum permissible water
supply rate must not be less than 4 liters
per minute and pressure must not exceed 7
bar.

WARNING: Don't leave the motor with
water inside at ambient temperatures less
than + 5 C° (41°F). Drain the water from the
motor (see chapter 9)

6.13 Mounting the drill bit on spindle

The size and peripheral speed of diamond core
drill bit should be selected according to the drilled
material quality and the hole diameter. The motor
spindle gearboxes (SG15, SG30, SG60) are equipped
with a standard 1-1/4-7" UNC thread. The cores with
other type of thread require use of adapters.
The motor spindles are equipped with antilock
collar for easier removal of the core bits.
Before mounting the core bit, tighten the screw
of antilock coupling and grease the spindle, to
facilitate removal of the core bit. The core bit has a
right-hand thread, use an open-end wrench SW 32
to hold the spindle in place.
For removing the core bit, use open-end wrenches
SW 41 and SW 32.
To thread off the core bit, loosen the screw of the
antilock collar, then the core bit will be much easier
to remove.

7.1.1 Powering the drill motor from a generator
or a transformer

When a transformer or a generator is required,
it is important to select one that is correctly sized
for your equipment or else you could run into
problems.
Single-phase 230V AC voltage 50/ 60 Hz, power
output must be at least 8.000 VA (8 kVA). The
operating voltage must at all times be within ±10%
of the rated voltage (230V).
Three-phase 400V AC voltage 50/ 60 Hz, power
output must be at least 20.000 VA (20 kVA). The
operating voltage must at all times be within ±10%
of the rated voltage (400V).

NOTE: If generator or transformer are
overloaded, during switching on and off
the power of the drill motor overvoltage

power peaks may occur, resulting in damage
to the core drilling machine. Never operate more
than one machine from one generator or
transformer at the same time.

7.5 Start of core drilling

 Before switching on the power of the drill motor,

move the motor so that the core bit is close to the
material to be drilled. Set the spindle speed to
minimum RPM (position 1).

 Open the water valve and water should start

coming out from the centre of the core drill bit.
Remember that too little water can cause the
diamond segments to overheat but too much
water flow washes away the abrasive slurry which
is needed to prevent the segment from wearing
away and to keep fresh diamonds exposed.

 While holding the feed handle securely, switch

the locking mechanism of the carriage to "down"
position

 When the motor is switched on, make sure the

core bit is not vibrating, and if excessive vibration
of the core bit is detected – stop, and change the
core drill bit.

 Move the core drill motor and the rotating core

bit closer to the material and, pressing lightly,
drill about 1-2 cm into the material. This approach
results in good centering and makes drilling much
easier.

 After the drill bit is centered, increase the core

drill motor forward speed and apply more contact
pressure, until one of status indicator LEDs lights
with yellow or red color (see chapter 7.3). The
optimal spindle speed depends on the drill bit
diameter, type of concrete and rebar amount.
Remember that having forward speed too low
leads to polishing of diamond sectors but having
excessively high forward speed causes segments
to wear sooner.

 In case of over-drilling, when a new larger

diameter hole must be drilled around the existing
hole of smaller diameter, the diameter of the new
hole must be at least 15-20 mm larger than the
diameter of the existing one.

 Small parts of the drilled material can jam the core

bit. If you encounter this problem, stop the drill
motor, pull the core out of the hole and remove all
the parts that were jamming the core bit and then
continue with drilling operations.

 In case the electric power unexpectedly goes

off, the drill motor automatically switches to
the Emergency stop mode. This mode protects
operator from injury by blocking the operation of
the motor and motor controls, in case the power
unexpectedly turns back on. To restart drill motor,
press and hold the START/STOP button for 2
seconds, release it and then press it again.

7.6 Drilling through iron

 When core bit starts cutting steel, the drill motor

movement would slow and color of the slurry
usually would change to brown or gray. Drop
the motor speed down a little and decrease the
pressure. Make sure that the water flow is quite
high when drilling in iron, to prevent the core bit
segments from getting overheated.

7.7 Angled drilling

 Set the spindle speed to minimum RPM

(position1), move the core drill motor and
the rotating core bit closer to the material
and pressing lightly, while avoiding excessive
core bit vibration, drill until the entire drill bit
circumference penetrates the material.

 Increase the core drill motor forward speed and

contact pressure, while avoiding excessive core bit
vibration.

7.8 Drilling with a large-diameter or a
longer drill bit

 Drilling holes larger than 0.4 meter in diameter, or

holes deeper than 1.5 meter requires special care
from the operator.

 Use two anchors, not less than M16 in size, as

widely spaced in the drill base plate anchor slot as
possible.

 To secure properly the base plate, fix the anchor

bolts evenly, then use the leveling screws to
tighten the drill base against the anchor bolt or
stud.

 Make sure that the drill motor is properly fixed

on the carriage and carriage rollers are snugly
adjusted to the track with the eccentric bolts.
This will eliminate excessive vibration during the
drilling

 Set the spindle speed to minimum RPM (position1),

move the core drill motor and the rotating core bit
closer to the material and, pressing lightly, drill
about 1-2 cm into the material. This approach
results in a good alignment from the start and
subsequently the friction between the drill bit and
the walls of the hole will be greatly reduced and
the motor power during the drilling will be much
lower.

 After the drill bit is centered, increase the core

drill motor forward speed and contact pressure.
The optimal spindle speed depends on the drill bit
diameter, type of concrete and rebar amount.

7.9 Core bit jamming

WARNING: Do not attempt to unclamp the

core bit when the motor is switched on!

 Try to unclamp the core bit by rotating the bit in

reverse with your core drill wrench, taking care
not to damage the core bit. Usually this action will
release the wedge enough for you to pull the bit
from the hole.

7.10 Deep drilling with shaft extension

The shaft extension rods allow drilling deeper than
the length of the core drill bit:

 Follow the above operating instructions, drill up

to the end of the core bit.

 Stop the drill motor, pull the core bit out of the

hole and remove the core.

 Place and secure the proper core bit extension

rod between the core bit and the core drill motor.

 Insert the core bit into the hole and proceed

drilling.

7.11 Reverse gear

The reverse gear can be used for removing the
diamond drill bits.
When RPM wheel is set to “R” while the motor is
running, the spindle will automatically stop. The
motor status LEDs will change color to light blue.
When the spindle has stopped, push the motor
START/STOP button and the spindle will start slowly
rotating in reverse direction.

8. Service time alert

Indicates that service is required. After the machine
total cumulative run time reaches 200 hours, when
the power is connected, LED1, LED2, LED3 LED’s will
blink with 1Hz frequency with blue colour light for 30
seconds. After 250 hours run time is reached, the
warning signal for service is stopped automatically
and will no longer flash.

 In case of a core bit jamming be ready to turn off

the drill motor.

 CM-10 drill motor is equipped with a slip

mechanical clutch that disengages the core bit
from the motor when the torque on the core bit
exceeds the maximal allowed value. In this way the
clutch safeguards gear wheels, shafts and other
drive elements of the drill motor from damage
and thus guarantees operational reliability.

 In case of jamming, switch the motor off

immediately.

WARNING: If the machine has NOT been
serviced by an authorised service workshop
after 250 hours of run time, the “service
required” signal is not reset, and remains in

the memory as a fault code. This will void the

 Prior to operating the drill motor, inspect the

feeding cable and extension cords, making sure
they don’t have any damage. If you find a damage,
ask authorized service centre for replacements.

 during storage there should be no fluctuations in

temperature and humidity, which cause the dew
formation;

 when storing boxed motors, inscriptions and

markings on the packaging should be followed.

10. Transportation

During transportation, loading, and unloading of
the motor its integrity must be ensured.
The motor should be packaged in the original
(preferably) or comparable box.
Motors are allowed to be transported by any kind of
covered transport at any distance.
When transporting the motor, the motor should
be positioned horizontally and its shaft axis must
be positioned perpendicular to the direction of
movement of the vehicle to prevent damage to the
bearings.
When transporting and moving motors, it is
necessary to ensure they don’t come into contact
with other items in such a way that can cause
damage.

11. Storage and preservation

The following conditions must be met when storing
drill motors:

 motors should be stored within or without
