for the working efficiency and service life of the diamond core drilling
crown as is excessive water pressure, which causes completely clear
water to flow out. Continue boring until the core-drilling operation is com-
plete. PREVENT ACCIDENTS: The drive unit should be held firmly
throughout in order to prevent torque-related jarring. Check to ensure
correct stability. Carry out larger core-drilling operations with the drill
upright. Ensure that no water is allowed to get into the drive unit motor
during operation. DANGER OF FATAL ACCIDENT!
3.3. Ways of securing the drill upright
You are recommended to secure the drill upright without the drive unit
and diamond core drilling crown. The drill upright becomes top-heavy
when the drive unit is attached. This makes the task of securing it more
difficult.
3.3.1. Securing with plugs in concrete with knock-in anchor (Fig. 5)
For core-drilling operations in concrete, the drill upright should be secured
with a knock-in anchor (steel plug). Proceed as follows:
Mark plug hole at a distance of approx. 220 mm (Simplex and Duplex),
approx. 290 mm (Duplex 300) from the centre of the core hole. Make
the Ø 15 mm plug hole, with a drilling depth of about 55 mm. Clean the
bore hole, hit the knock-in anchor (23) in with a hammer and spread with
the flattener (24). Use only knock-in anchors of approved type (art. no.
079005). Observe approval! Screw the knurled threaded rod (25) into
the knock-in anchor and tighten it by holding a tool such as a screw-
driver in the transverse hole of the knurled threaded rod. Turn the four
adjustment screws (5) on the drill upright until they no longer protrude
from the sole plate. Position the drill upright with slot (7) on the knurled
threaded rod, while observing the desired position of the core-drilling
operation. Fit the washer (26) to the knurled threaded rod and use an
SW 19 wrench to secure the fast-tightening nut (27). Turn all four ad-
justment screws (5) with the SW 19 wrench to compensate for irregu-
larities in the ground surface. Take care to ensure that the locknuts do
not prevent movement of the adjustment screws. Tighten the locknuts
as required.
3.3.2. Securing with plugs in masonry, with expansion anchor
(anchor sleeve, fig. 6)
For core-drilling operations in masonry, the drill upright should be se-
cured with an expansion anchor (anchor sleeve). Proceed as follows:
Mark plug hole at a distance of approx. 220 mm (Simplex and Duplex),
approx. 290 mm (Duplex 300) from the centre of the core hole. Make
the Ø 20 mm plug hole, with a drilling depth of about 85 mm. Clean the
bore hole, and push the expansion anchor (28) with knurled threaded
rod (25) into the hole. Screw the knurled threaded rod (25) fully home
and tighten it by holding a tool such as a screwdriver in the transverse
hole of the rod. Turn the four adjustment screws (5) on the drill upright
until they no longer protrude from the sole plate. Position the drill upright
with slot (7) on the knurled threaded rod, while observing the desired
position of the core-drilling operation. Fit the washer (26) to the knurled
threaded rod and use an SW 19 wrench to secure the fast-tightening
nut (27). Turn all four adjustment screws (5) with the SW 19 wrench to
compensate for irregularities in the ground surface. Take care to ensu-
re that the locknuts do not prevent movement of the adjustment screws.
Tighten the locknuts as required.
The expansion anchor can be removed after completion of the core-dril-
ling operation for reuse elsewhere. To do so, turn the knurled threaded
rod back by about 10 mm. A light tap on the knurled threaded rod will
release the pin of the expansion anchor, allowing it to be removed.
3.3.3. Securing to masonry with a threaded rod
When drilling in porous masonry, note that it is not sufficient to secure
the drill upright with plugs. It is recommendable in these cases to drill
right through the masonry and secure the drill upright with a threaded
rod (e.g. M12), secured from the other side by a washer and nut.
3.3.4. Securing with vacuum suction
When carrying out core-drilling operations on items with shiny surfaces
(e.g. tiles or marble) that do not permit securing with plugs, the drill
upright can be secured by vacuum suction. Check the suitability of the
surface for vacuum suction. This method of securing is suitable for the
REMS Duplex and Duplex 300. The required drill-upright components
are supplied with the unit. Proceed as follows:
Place the sealing ring (43) into the channel on the underside of the sole
plate (6). Close off the slot (7) in the sole plate (6) with the cover plate
with hose connection (42). Attach a conventional vacuum pump to the
hose connection (41), and secure the underside of the drill upright by
suction. Check the vacuum pressure constantly during drilling (pressure
gauge). Observe the operating instructions supplied with the vacuum
pump. Operate the drill at low feed pressure.
3.3.5. Securing with a quick-action upright
The REMS Duplex and Duplex 300 also offers the possibility of secu-
ring the drill upright between the floor and ceiling, or between two walls.
This is done, for example, by placing a conventional quick-action upright
or a 1 1 / " steel pipe between the grip head (29) of the drill upright and
4
the ceiling/wall, and tightening it by holding a tool such as a screwdriver
in the transverse hole. Tighten the locknut (30).
Note that the quick-action upright or steel pipe must be aligned with the
boring trestle, and that the threaded spindle (33) should be screwed by
at least 20 mm into the thread of the boring trestle, and into the thread
of the grip head, in order to guarantee a stable support. Use a piece of
wood or metal to distribute the pressure force of the quick-action upright
evenly on the ceiling or wall.
3.4. Dry-boring with drill upright
REMS Picus S1 and REMS Picus S3
Secure the drill upright using one of the methods described in 3.3. Insert
the drill collar (13) of the drive unit into the mounting in the clamping
angle (10), and tighten the fillister head screw(s) (8) with an SW 6 hexa-
gon socket head wrench. Screw the selected diamond core drilling crown
onto the drive spindle (11) of the drive unit, and lightly hand-tighten.
There is no need to tighten it with a wrench.
Using the dust-extraction system (see 2.4.2.). If the dust produced by
dry boring is not removed, the diamond core drilling crown may overheat
and suffer damage. There is also a danger of the compressed drilling
dust in the gap causing the diamond core drilling crown to become
blocked.
Activate the drive unit at the switch (21). Push in the switch and press
the orange button forward to lock it. Slowly advance the diamond core
drilling crown with the feed lever (4), and carefully tap the drill hole. Once
the annular bit has engaged all-round, the feed rate can be increased.
If the drive unit is stopped due to excessive feed pressure, or becomes
blocked as a result of resistance in the drilling gap, the multi-function
electronic system reduces the motor current – and thus the turning speed
of the drive unit – to a minimum. The drive unit does not shut down how-
ever. As the feed pressure is reduced, the turning speed of the drive unit
is increased once more. This procedure, even if it is repeated several
times in succession, prevents damage to the drive unit. If the motor
remains stopped despite the reduction in feed pressure, the drive unit
must be shut down and the diamond-tipped annular bit freed manually
(see 5.). Pull out the mains plug!
REMS Picus S2/3,5
Loosen the two screws (52) on the flange of the REMS Duplex 300, in-
sert REMS Picus S2/3,5 in the guide (53). Hold the drive machine and
tighten the screws (52). Tighten the locking nut. Screw the selected dia-
mond core drill crown to the drive spindle (11) of the drive machine and
tighten by hand with a slight swing. There is no need to use an open-
ended wrench for tightening. Switch on drive machine with switch (21).
Push in the switch and press the orange button forward to lock it. Slowly
advance the diamond core drilling crown with the feed lever (4), and
carefully tap the drill hole. Once the annular bit has engaged all-round,
the feed rate can be increased. If the drive unit is stopped due to ex-
cessive feed pressure, or becomes blocked as a result of resistance in
the drilling gap, the multi-function electronic system reduces the motor
current – and thus the turning speed of the drive unit – to a minimum.
The drive unit does not shut down however. As the feed pressure is re-
duced, the turning speed of the drive unit is increased once more. This
procedure, even if it is repeated several times in succession, prevents
damage to the drive unit. If the motor remains stopped despite the re-
duction in feed pressure, the drive unit must be shut down and the dia-
mond-tipped annular bit freed manually (see 5.). Pull out the mains plug!
Important: Always wet drilling for steel-reinforced concrete!
