In this configuration, the REMS Duplex can be used to drill at up to Ø
132 mm. For larger core-drilling operations, the spacer (38, supplied
with unit) must be inserted between the feed slider (2) and clamping
angle (10), and secured with the long fillister head screws. The spacer
should however only be fitted if you actually intend to drill at > Ø 132 mm,
as the drive unit runs in a more stable way without the spacer.
REMS Duplex 300 is immediately ready for operation upon delivery.
The boring trestle (1) of REMS Duplex and REMS Duplex 300 is infini-
tely adjustable up to an angle of 45°. This allows angled core-drilling
operations to be carried out within this range. To adjust the angle, use
a wrench to loosen the screws (37) at the foot of the boring trestle (1),
along with all the screws on the two struts (40). The boring trestle can
now be swivelled to the desired position. Retighten all screws before
proceeding. The swivel adjustment of the boring trestle causes the use-
ful stroke range of the feed device of the REMS Duplex to increase or
decrease accordingly. This means that you may have to use corre-
sponding annular-bit extensions (see 3.7.).
The feed slide (2) can be locked in certain positions on the drill stands.
In the case of the REMS Simplex, this is done by moving the slotted
sleeve (3) on the feed shaft, while at the same time turning the feed le-
ver axially in relation to the feed-mechanism housing until it engages.
On REMS Duplex and REMS Duplex 300, push the sliding bolt (36) in
the direction of the struts and turn the feed lever (4) at the same time
until the sliding bolt snaps into place.Locking prevents such undesired
movements as the accidental lowering of the drive unit while the dia-
mond core drilling crown is being replaced.
On the REMS Simplex, REMS Duplex and REMS Duplex 300, the feed
lever (4) can be secured, in accordance with operating conditions, on
either the right- or left-hand side of the feed slider (2). The feed slider
should be locked, as described above, when doing so. In the case of
the REMS Simplex, the turning handle (9) and two washers on the op-
posite side of the feed lever are removed; then the feed shaft is pulled
out of the feed-mechanism housing, along with the feed handle, and
pushed in again from the other side. Refit the washers and turning handle.
On the REMS Duplex and REMS Duplex 300, only the feed lever (4) is
pulled off the feed shaft. It is then pushed onto the shaft butt end on the
opposite side.
3. Operation
Connect by plugging into the mains supply. Always check the PRCD
fault-current safety switch (19) for correct functioning before starting a
drilling operation. To do so, press the RESET button (17) and watch for
the red indicator light (16, operating status). The indicator light should
go off when the mains plug is pulled out. Push the mains plug back into
its socket and press the RESET button. The indicator light should be
red (operating status). Press the TEST button (18), and the indicator
light should go out. Press the RESET button (17) again, and the drive
unit is ready for operation.
Important: DO NOT start drilling operations if any of the above PRCD
functions are defective! DANGER OF FATAL ACCIDENT!
Different material characteristics (concrete, steel-reinforced concrete,
porous or solid masonry) require different and varying feed pressures
on the diamond core drilling crown. Further influence is brought to bear
by the varying peripheral speed and size of the bit. It is inevitable, espe-
cially during manually controlled boring, that the machine will occasio-
nally become slightly tilted as it operates. These factors, which are merely
examples of those that might arise, can lead to overloading of the drive
unit during drilling operations. You will normally hear the turning speed
of the motor drop, although the diamond core drilling crown may become
completely blocked. This can lead, especially during manually-controlled
boring, to torque-related jarring – which will affect the operation.
Important:Note that the diamond core drilling crown can become blocked
at any time. During manually controlled core drilling, there is a danger
of the drive unit jumping out of your hands.
In order to simplify the handling of the machine, and to avoid damage,
the REMS Picus S1, REMS Picus S3 and REMS Picus S2/3,5 are
equipped with a multi-function electronic system, along with a mecha-
nical sliding clutch. The multi-function electronic system performs the
following tasks:
Initial-current limitation and jerk-free startup for smooth tapping.
•
Limiting of idling speed in order to reduce noise and prevent wear to the
•
motor and transmission.
Motor overload regulation relative to feed pressure. Before the drive unit
•
can be overloaded by excessive feed pressure on the diamond core dril-
ling crown, or as the result of a blockage, the motor supply current – and
thus its turning speed – is reduced to a minimum. The drive unit does
not shut down however. 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 pres-
sure, the drive unit must be shut down and the diamond-tipped annular
bit freed manually (see 5.).
Important: DO NOT switch the drive unit on and off in an attempt to free
a blocked diamond core drilling crown.
3.1. Manually-controlled dry boring REMS Picus S1 and
REMS Picus S3
Important: Never carry out manually-controlled drilling without first
fitting the holder-up. DANGER OF ACCIDENTS!
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 tapping tool (see 2.4.1.). Secure the drive
unit to the motor handle (20) and holder-up (12), and locate the tapping
tool at the centre of the desired core-drilling point. Activate the drive unit
at the switch (21).
Important: Avoid accidents: NEVER block the drive unit switch during
manually-controlled boring! If the drive unit is knocked out of your hands
as a result of a blocked diamond core drilling crown, a blocked switch
can no longer be released. The drive unit will then run out of control,
and the unit must be shut down by unplugging it from the mains supply.
To make a tapping hole, drill until the diamond core drilling crown has
bored to a depth of about 5 mm. Pull out the mains plug. Remove the
tapping tool, using a SW 19 wrench if required. Using the dust-extrac-
tion system (see 2.4.2.). Continue boring until the core-drilling operation
is complete. PREVENT ACCIDENTS: The drive unit should be held
firmly throughout in order to prevent torque-related jarring. Check to en-
sure correct stability. Carry out larger core-drilling operations with the
drill upright.
If the dust produced by dry boring is not removed, the diamond core dril-
ling crown may overheat and suffer damage. There is also a danger of
the compressed drilling dust in the drilling gap causing the diamond core
drilling crown to become blocked. If you need to work without the dust-
extraction system when handling fine-pored materials, pull the diamond
core drilling crown out at regular intervals and push it back in with a slight
turn, so that the drilling dust is expelled from the drilling gap.
Important: Always wet drilling for steel-reinforced concrete!
3.2. Manually-controlled wet drilling REMS Picus S1 and
REMS Picus S3
Important: Never carry out manually-controlled drilling without first
fitting the holder-up. DANGER OF ACCIDENTS!
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. Connect the water supply (see 2.5.). Using the tapping
tool (see 2.4.1.). Secure the drive unit to the motor handle (20) and
holder-up (12), and locate the tapping tool at the centre of the desired
core-drilling point. Activate the drive unit at the switch (21).
Important: Avoid accidents: NEVER block the drive unit switch during
manually-controlled boring! If the drive unit is knocked out of your hands
as a result of a blocked diamond core drilling crown, a blocked switch
can no longer be released. The drive unit will then run out of control,
and the unit must be shut down by unplugging it from the mains supply.
To make a tapping hole, drill until the diamond core drilling crown has
bored to a depth of about 5 mm. Remove the tapping tool, using a SW
19 wrench if required. Adjust the pressure in the water supply system
(15) to a point where there is a moderate, but constant, flow for water
from the bore hole. Insufficient water pressure (where the waste mate-
rial flows out of the bore hole as thick sludge rather than liquid) is as bad
