• Check up if slide way moves without excessive frictional
resistance. Machine can be only connected to the net equipped with
earth protective pin. In case of non correct connection of grinding
machine an electric shock may occur.
• In case, the plug does not suits to the socket, a qualified
electrician intervention is necessary, in order to fit the plug and the

Never start the machine if some equipment element is missed, or machine is not
carefully assembled. Not respecting this prohibition may cause the accident and
serious injury. Avoid fingers contact with grinding disc, or other dangers in case the
grinding disc pushes away from the shaft.
IV. TRANSPORT AND
STORING
Storing conditions
Machine is delivered in original factorypacking. We recommend for long-term storing
to keep machine in dry surroundings in factorypacing, in temperature from -20° C do
50° C.
Transport conditions
Machine is designed for hand loading and transporting in work place. For long
distances can be transported by any transport medium. Please take care of you to
prevent the machine’s movement on slide ways under inertial force.
Before machine displacement:
• Turn off machine with button on position”0”
• Pull out the power cord from the socket
• Check up the condition of screws elements.
• Carry over the machine holding the machine’s base with both hands

2.1.
Dividing disc e xc h a n ge
Dividing discs (point 6.1. pos. 11) of ACG-1450Grinding machine are
responsible for
accurately re-sharpening of core drill depending on the number of teeth. The basic
equipment of machine consist of following dividing disc: T - 8 for core drills with 4 or 8
teeth, T - 10 for core drills with 5 or 10 teeth, and T - 6, T - 7, T - 9, (for core drills
with 6, 7, 9 teeth).
Dividing disc exchange
Choose the dividing disc suitable for the number of
core drill teeth. In order to exchange the dividing
disc, first turn the star wheel in CW direction until the
fixing screw (a) appears in upper position. Tight the
bolt (b) with hex key 2,5. Untighten the screw with
star wheel (pt 6.1. pos. 13) in CCW direction
Untighten screw (a) on dividing disc (use hex key
2,5)
and pull out the disc.
Dividing disc assembly
Place the chosen dividing disc on the spindle. It is
important to draw attention, that screw (a) appears
under the spindle slot (see drawing.). Screw gently
the screw (a) with hex key 2,5) to position the slot
(do not tighten). Tight the screw with star wheel in
CW direction. Next tight screw (a) placed on dividing
disc and loosen the screw (b) (upper drawing).

2.2. Core drill a d j u s t i ng
rs
Warning! Edges of core drills are sharp. Please avoid injury!
Turn the arbor holder onto position 90 ° (see
drawing.)
When placing the core drill inside the arbor,
please draw your attention the fixing screw
locates with the cylindrical surface of Weldon
shank ( not flat surface) of the core drill. (Do
not tighten the screw). This is necessary to
avoid the core drill position change during
screw tight, what could result incorrect set up.
The laser ray enables core drill accuracy
positioning in the arbor (right drawing) .
Wheel head support (pt 6.1. pos. 9) has got
white line (see drawing). During laser ray
positioning, its light must be always on this line

With the spindle of laser indicator guiding, set up laser indicator, to fit exactly to the
external cutting edge (see drawing).
Laser ray is switched on by small button placed on cylindrical indicator’s body. Now
the user should turn the cutter slightly in the arbor, in order that the laser ray lights up
exactly the on the external cutting edge . Fix the cutter in this position tightening the
screw, placed on the cylindrical surface of Weldon arbor with hex key 4.
!! MARK THE POSITIONED TEETH WITH THE MARKER!
3. Regular
w or k
Always wear glasses during re-sharpening works.
There are two tooth forms of core drills. Core drills with flat tooth and with V-shape
tooth. Standard type core drills are V shape tooth. Non-standard core drills are
equipped alternately with flat and V-shape tooth. This machine is designed to re-
sharpen in first line tooth on internal side and next on external side. In case of non-
standard core drill re-sharpening first are re-sharpen V-shape tooth and next flat
tooth.

3.1. Core drills
r e- s h a rp e n i ng
Core drills, although available in two sorts are manufactured by different
manufacturers.

Core drill setting for internal surface re-sharpening
Cuttermasters
NY, USA –ON, Canada •[phone] •[phone]

First step.
Set up the angle on wheel head support at 20 °
Set up the arbor angle at 7,5 °
!! Remember to use the correct dividing disc !!
After both angles settings, move the cutter with the guide and motor feed mechanism
to the grinding disc. Re-sharpen the tooth which is directed into the middle of grinding
disc, nearest to the “3 o’clock” position. (This one which position was settled up with
the laser ray and marked with the marker).
Move the support up to the tooth contact with the grinding disc. Lock the handle of
the bumper in this position (see drawing).
With micrometric screw move back the guide slightly, just so the grinding disc did not
touch the next tooth.
Start re-sharpening the tooth from internal surface, mowing the guide forward and
backwards. Motor feed should be realised carefully and with the same value for all
teeth.
After the first tooth re-sharpening , move back the guide and turn the star wheel in
CW direction until the dividing disc will match the next position. Do not change the
motor feed setting. Repeat above work until all teeth will be re-sharpened.
