NOTICE
Remove dirt from between rack and slide immediately otherwise the slide can
block. The rack and slide could also be damaged.
2.7 Laser drilling centre pointer
To position the REMS drill stand, the laser drilling centre pointer ((58) accessory
art. no. 183604) is inserted into the clamping bracket (10) and tightened with
the fi llister head screws (8). After switching on the laser drilling centre pointer,
the drill stand can be aligned accurately at the marked drilling centre with the
laser point and fi xed in position.
WARNING
Do not look directly into the laser beam!
2.8 Drilling template REMS Titan
A drilling template ((64) accessory art. no. 183605) can be used for REMS Titan
for easier location of the plug hole.
3 Operation
Use eye protection
Use ear protection
Suitable safety vacuum cleaners/dust extractors, e.g. REMS Pull M, a respirator
and disposable overalls must be used for work which could produce health
hazardous dusts. Observe the national regulations.
Plug the mains plug into the socket. Check the function of the PRCD fault
current circuit breaker (19) every time before starting drilling (see 2.1 Electrical
Connection).
Different material characteristics (concrete, steel-reinforced concrete, porous
or solid masonry) require different and varying feed pressures on the diamond
core drilling crown. Further infl uence is brought to bear by the varying periph-
eral speed and size of the bit. It is inevitable, espe cially during manually controlled
boring, that the machine will occasionally 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-
con trolled boring, to torque-related jarring – which will affect the operation.
WARNING
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, REMS Picus S2/3,5 and REMS Picus SR
are equipped with a multi-func tion electronic system, along with a mechanical
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 drilling 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.).
NOTICE
DO NOT switch the drive unit on and off to loosen a jammed diamond core
drilling crown. This can cause a machine defect (see 5.1.).
3.1 Manually-controlled dry boring REMS Picus S1, REMS Picus S3 and REMS
Picus SR (fi g. 4)
WARNING
Use the brace (12) provided with the power tool for hand-held drilling. Losing
control of the power tool can cause injuries. Always be prepared for blocking
of the diamond core drilling crown. Never use stage 1 for hand-held drilling with
REMS Picus SR. There is a danger of injury from the power tool being torn
from the hand and spinning round as the torque increases.
CAUTION CAUTION
When drilling dry by hand, the mounted water supply system (15) gets in the
way and should be removed. The holder for the water connection must be
sealed with the lid (14) otherwise dust can get into the machine.
Use dust extraction and suitable safety vacuum cleaner/dust extractor, e.g. REMS
Pull M. 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 (49) (see 2.4.1.). Secure the drive unit to the
motor handle (20) and holder-up (12), and locate the tapping tool (49) at the
centre of the desired core-drilling point. Activate the drive unit at the switch (21).
Switch on the drive unit with safety inching switch (21).

Use a respirator
Use hand protection
3.2 Manually-controlled wet drilling REMS Picus S1, REMS Picus S3 and
3.3 Ways of securing the drill upright
3.3.1 Securing with plugs in concrete with knock-in anchor (fi g. 5)
WARNING
Never lock the safety inching switch (21) of the drive unit during hand-held
drilling (Risk of injury)! If the drive unit is knocked out of your hand by a
blocking diamond core drilling crown, a locked safety inching switch can no
longer be unlocked. 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 (49), 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 fi rmly throughout in order to prevent torque-related jarring. Check
to ensure correct stability. Carry out larger core-drilling operations with the drill
upright.
Make sure that the suction hose of the safety vacuum cleaner/dust extractor
does not kink and impair the dust extraction. Also make sure that no fragments
of stone or other objects jam in the diamond core drilling crown, the suction
rotor ((46) accessory art. no. 180160) and/or the suction hose. Empty the dust
bag of the safety vacuum cleaner/dust extractor early and clean/renew the fi lter
regularly. Observe the operating instructions of the safety vacuum cleaner/dust
extractor.
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
fi ne-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. Suitable safety equipment, e.g. respirator, disposable overalls,
must be used. Observe the national regulations.
NOTICE
Always wet drilling for steel-reinforced concrete!
REMS Picus SR
WARNING
Use the counter-holder (12) delivered with the power tool for hand-held
drilling. Losing control of the power tool can cause injuries. Always bear in
mind that the diamond core drilling crown could block at any time. Never use
stage 1 for hand-held drilling with REMS Picus SR. There is a risk of injury from
the power tool being torn out of your hand and spinning round as the torque
increases.
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 (49) (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. Switch
on the drive unit with safety inching switch (21).
WARNING
Use the counter-holder (12) delivered with the power tool for hand-held
drilling. Losing control of the power tool can cause injuries. Always bear in
mind that the diamond core drilling crown could block at any time. Never use
stage 1 for hand-held drilling with REMS Picus SR. There is a risk of injury from
the power tool being torn out of your hand and spinning round as the torque
increases. 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 (49), 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, fl ow for water from the bore hole. Insuffi cient
water pressure (where the waste material fl ows out of the bore hole as thick
sludge rather than liquid) is as bad for the working effi ciency and service life
of the diamond core drilling crown as is excessive water pressure, which causes
completely clear water to fl ow out. Continue boring until the core-drilling
operation is complete. PREVENT ACCIDENTS: The drive unit should be held
fi rmly throughout in order to prevent torque-related jarring (danger of injury)!
Check to ensure correct stability. Carry out larger core-drilling operations with
the drill upright. Suck up the drilling water preferably with a suitable dry and
wet vacuum cleaner, e.g. REMS Pull L or REMS Pull M.
WARNING
Ensure that no water is allowed to get into the drive unit motor during
operation. DANGER OF FATAL ACCIDENT!
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 diffi cult.
For core-drilling operations in concrete, the drill upright should be secured with
a knock-in anchor (steel plug). Proceed as follows:
