SECTION 1: INTRODUCTION
1.1 INTRODUCTION
The AcuDrill dri ing machine is especia y designed to dri on mains, under pressure or
pressure ess, on any type of materia : gray-iron casting, ducti e casting, PVC, PE, PP,
asbestos cement, po yester, c ay, stee , etc. It is especia y designed to be used on branch
connections or threaded accessories.
The machine dome is connected to the threaded out ets of sadd es through threaded
adapters. The sizes of the avai ab e adapters are 3/4", 1", 1¼”, 1½” and 2" BSP. It a ows
ho es of up to 48 mm diameter to be dri ed, using standard ho e saws of high-speed stee
or tungsten carbide tipped ho e saws with coupon retainer-equipped pi ot dri . The
chuckshaft can be fixed in three different positions according to the position of the
accessories to be dri ed.
It can be operated manua y by means of a ratchet wrench provided with a revo ving
hand e, a though it is designed to be used through a swive gear with either an e ectric,
pneumatic or hydrau ic actuator.
For dri ing mains under pressure, the maximum a owab e pressure is 16 bar (for water
mains) and 5 bar (for gas mains).
The machine is equipped with an absorbing mechanism that ensures a soft and regu ar
operation system of the dri and ho e saw over the pipe during dri ing, absorbing
excessive feed that cou d ead to b ocking of the ho e saw, a owing continuous dri ing.
The set inc udes a dome with bui t-in spind e, a machine body, chuckshaft, two arbor ho e
saws with pi ot dri (with coupon retainer system), an spanner for the dome adapters,

SECTION 3: MODE OF OPERATION
3.1 DRILLING UNDER PRESSURE O ER ACUSTOP-R BRANCH CONNECTIONS
3.1.1 Initial operations:
Before performing the drilling operations, ensure that you have all
the necessary material and that it is in good condition.
CComplete drilling machine.
CArbor hole saw (with pilot drill installed) matching the size of
the hole saw to be used.
CHole saw of the diameter to be used.
CAdapter (with washer) of the diameter of the thread matching
the saddle to be installed.
CTools: 3 mm Allen key, adapter spanner, 17 mm open-end
spanner, ½” ratchet wrench (manual drilling) and electrical
or pneumatic swivel gear with chuckshaft adaptation
elements (if applicable).
3.1.2 ranch connection installation:
The installation of the AcuStop-R branch connection is performed
placing the saddle and sealing gasket on the pipe. Next, fasten the
clamp between the saddle and mains (the hinge joints should remain
above the saddle), equally tightening the two fastening bolts to
ensure tightness.
For more information, refer to the Fitting Instructions
included with the accessory.
Figure 4
3.1.3 Assembly of the drilling machine:
CSet up the arbor hole saws with the pilot drill in the chuckshaft. Screw the hole
saw matching the threaded outlet of the branch connection into the arbor hole
saw. See Figure 5.
CChoose the adapter that matches the thread of the saddle and screw it into the
machine dome. See Figure 6.
This operation can be performed manually. If necessary, use the dome
adapter spanner included with the equipment.
CFor this type of branch connection, position the retention mechanism in the lowest
of the three anchoring openings on the chuckshaft. See Figure 7.

CPlace the body of the machine in its upper position (unscrew it until the end travel
mechanism is released). Now install the AcuDrill drilling machine by screwing it
onto the saddle of the branch connection. The adapter must have the washer
installed.
WARNING !
If the support face of the saddle is not flat enough, apply Teflon tape to
the adapter thread to achieve tightness.
Manually tighten the machine body. If necessary, retighten using the
dome adapter spanner included with the equipment.
3.1.4 Pressure test:
Once the drilling machine set and accessories are installed on
the saddle of the branch connection, perform a pressure test.
To do so, apply compressed air through the venting valve to
check tightness of the assembly (see Figure 8).
Once the interior is pressurized, and with the venting valve
closed, check for leaks in the threaded connections or the
gasket at the mains head seat gasket using a spray detector or
soapy water. Correct in case of leaks.
Once the check is complete, open the venting valve to
depressurize, then leaving it in the “closed” position.
Figure 8

USER MANUAL
AcuDrill DRILLING MACHINE
Edition: June 2016
- MODE OF USE Revision: No. 4 14
3.1.5 Drilling the mains:
Once the pressure test is complete, lower the chuckshaft by rotating the machine body
(with your hand in the knurled area), until the pilot drill makes contact with the pipe (the
chuckshaft will have risen depending on the contact force: see measurement a of Figure
9). At this point, withdraw the tip of the drill from the pipe by approximately one turn.
Now begin drilling the mains by activating the chuckshaft using the ratchet wrench, if
drilling is manual, or through the electrical or pneumatic swivel gear.
SWI EL GEAR
If an electrical actuation swivel gear (drilling machine) or pneumatic
swivel gear (pneumatic, non-impact tool) is used, the following
considerations must be taken into account:
C The rotation speed must be that indicated by the hole saw
manufacturer.
C The adapter components may be supplied by Acuster Global, SL.
C The usage and safety recommendations given by the manufacturer
must be followed.
The feed is achieved by making the machine body rotate
(with the hand placed in the knurled area). The
recommended distance produced by the feed is a = 1 or 2
mm (see Figure 9) when drilling with the pilot drill. Once
perforated with the drill, remember that distance a will be
increased by the internal driving pressure. The feed limit is
indicated by a mechanized line on the fastening bush shaft.
If due to an excess of compression (feed + internal
pressure) this line becomes visible (see Figure 9), turn
slightly in the opposite direction to return to the previously-
recommended distance.
Ensure that the drilling is complete by making one or two
additional turns.
Figure 9
WARNING !
It is recommended to avoid excess feed, especially in the pilot drill work
phase, given that the drill could break specially at low revolutions.

USER MANUAL
AcuDrill DRILLING MACHINE
Edition: June 2016
Revision: No. 4 MODE OF USE - 15
3.1.6 Plugging the branch connection:
Once the mains has been perforated, move the chuckshaft up by turning the machine
body counterclockwise until the hole saw is positioned in the upper part of the dome.
Carefully open the venting valve to remove chip residues. Next, close the valve again.
Now carry out the plugging to facilitate disassembly of the machine and the subsequent
connection to the branch connection.
Figure 10 Figure 11
To do so, the slot in the saddle for the introduction of the spatula must be fully
accessible. Slightly raise the clamp-gasket assembly of the saddle closure to keep it from
interfering with the handle of the spatula during the introduction. See Figure 10.
The clamp-gasket assembly is delivered flush with the upper face of the
saddle and with the fastening bolt untightened.
Place the pivoting shaft of the spatula in the opening of the saddle (use the small spatula
to plug branch connections with threaded outlets of 3/4” to 1½” and the large spatula
for branch connections with 2” threaded outlet). Insert the spatula all the way to the
bottom through the slot of the saddle. See Figure 11.
3.1.7 Disassembly of the machine and accessories:
Before carrying out the disassembly of the drilling machine, check the tightness of the
spatula by opening the venting valve. There should not be any fluid overflow, unless it
is the amount remaining in the interior before fitting the spatula. Correct the position of
the spatula in case of leak or determine the causes of any possible loss.
Once the check is complete, return the venting valve to the closed position.
Disassemble the saddle adapter and drilling machine using the spanner designed for this
purpose.

The coupon resulting from drilling the main will have remained trapped by the pilot drill’s
coupon retainer mechanism. To extract the coupon, disassemble the drill by loosening the
Allen fastening stud. Remove the coupon through the upper part of the drill and fit it to
the arbor hole saw again. See Figure 12.
Figure 12 Figure 13
3.1.8 Connecting the branch connection:
Make the proper connections at the threaded outlet of the saddle. If necessary, perform
a pressure test on the new section.
Completely withdraw the spatula (to allow fluid flow). Next slide the exterior clamp-
gasket assembly all the way down. Tighten the fastening bolt of the exterior clamp-gasket
assembly to its end travel. See Figure 13.
The tightening bolt must remain positioned on the opposite side from the
spatula insertion slot, as it is delivered stock.
Retighten the fastening bolts of the branch connection.
