WARNING
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.
WARNING
Pull out the mains plug! Remove the tapping tool, using a SW 19 wrench if
required. Using the dust-extraction system (see 2.4.2.). Continue boring until
the core-drilling opera tion is complete. 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.
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 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.
NOTICE
Always wet drilling for steel-reinforced concrete!
3.2. Manually-controlled wet drilling REMS Picus S1, REMS Picus S3 and
REMS Picus SR
WARNING
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).
WARNING
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 material flows out of the bore hole as thick
sludge rather than liquid) is as bad 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 complete. 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.
DANGER
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 for REMS Simplex 2 at distance of approx. 200 mm, for REMS
Titan with clamping angle for REMS Picus S3 and Picus SR approx. 250 mm,
for REMS Titan with Picus S2/3,5 approx. 290 mm from the centre of the core
hole. Set plug hole Ø 15 mm, drilling depth approx. 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 30 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 ensure that the locknuts do not prevent movement of the
adjustment screws. Tighten the locknuts as required. The drill stand can be
aligned to drill a perpendicular hole using 4 adjusting screws (5) and the level-
ling block (56).
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 secured with
an expansion anchor (anchor sleeve). Proceed as follows:
Mark plug hole for REMS Simplex 2 at distance of approx. 200 mm, for REMS
Titan with clamping angle for REMS Picus S3 and Picus SR approx. 250 mm,
for REMS Titan with Picus S2/3,5 approx. 290 mm from the centre of the core
hole. Set plug hole Ø 20 mm, drilling depth approx. 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 screw driver 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 30 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
ensure 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-drilling
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. The drill stand can be aligned
to drill a perpendicular hole using 4 adjusting screws (5) and the levelling block
(56).
3.3.3. Fastening in masonry with quick clamping set 500
In porous masonry it is to be expected that plug fastening of the drill stand will
not be successful. In this case we recommend drilling completely through the
wall with a drill diameter of 18 mm and fastening the drill stand with the quick
clamping set 500.
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 Titan. The necessary
parts (Art. No. 183603) for the drill stand are not included in delivery. 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). Connect vacuum pump (67, Art. No. 183670) to hose connec-
tion (41) and suck drill stand tightly to the base. Check the vacuum pressure
constantly during drilling (pressure gauge). Observe the operating instructions
of the vacuum pump used. Drill with low thrust pressure. The vacuum pump
should be left switched on during drilling to prevent the drill stand accidentally
coming loose.
3.3.5. Securing with a quick-action upright
The REMS Titan also offers the possibility of securing 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 1¼" steel pipe between the grip head
(29) of the drill upright and the ceiling/wall, and tightening it by holding a tool
such as a screw driver 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, REMS Picus S3 and REMS Picus SR
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.
NOTICE
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). Lock the switch in the pressed state
by pushing the orange button forward (only Picus S1 and Picus S3). In Picus
SR the knob next to the switch (21) must be pressed to lock the pressed switch
(21). 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 elec tronic 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 repea ted several times in
succession, prevents damage to the drive unit. If the motor remains stopped
