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); not necessary for REMS Picus DP.
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 WARNING
Note that the diamond core drilling crown can become blocked at any
time. During hand-held core drilling, there is a risk of injury from the diamond
core drilling machine being torn out of your hand and spinning round as the
torque increases. Never use stage 1 for hand-held drilling with REMS Picus
SR.
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, REMS Picus SR and
REMS Picus DP are equipped with a multi-function 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 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.).
3.1.1 Manually-controlled dry boring REMS Picus S1, REMS Picus S3 and REMS
Picus SR (fi g. 4)
WARNING WARNING
Use the counterholder (12) provided with the diamond core drilling machine for
hand-held drilling. Losing control of the diamond core drilling machine 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 risk of injury from the diamond core drilling machine being torn out of your
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 REMS universal diamond core drilling crown/REMS
universal diamond core drilling crown LS onto the drive spindle (11) of the drive
unit and lightly hand-tighten. There is no need to tighten it with a wrench. Use
the G ½ UDKB tapping tool (49) (see 2.4.1.). Hold the drive unit by the motor
handle (20) and the brace (12) and place the G ½ UDKB tapping tool (49) in
the centre of the desired core hole. Switch on the drive unit with safety inching
switch (21).
Use a respirator
Use hand protection
3.1.2 Hand-held dry drilling REMS Picus DP (Fig. 10)
WARNING 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 WARNING
Pull out the mains plug! Screw out the G ½ UDKB tapping tool (49); loosen
with a size 19 open-ended wrench if necessary. Using the dust-extraction
system (see 2.4.2.). Continue boring until the core-drilling opera tion is complete.
Always hold the drive unit by the insulated grip surfaces to safely absorb torque
surges (risk of accident!). 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 NOTICE
Always wet drilling with REMS universal diamond core drilling crowns
and REMS universal diamond core drilling crowns LS for steel-reinforced
concrete!
Always dry drilling with REMS dry diamond core drilling crowns LS with
core drilling machines with micro-pulse technology. Suck off the resulting
drilling dust with a suitable safety vacuum cleaner/dust extractor! Observe
the national regulations.
WARNING WARNING
Use the counterholder (12) provided with the diamond core drilling machine for
hand-held drilling. Losing control of the diamond core drilling machine can
cause injuries. Always bear in mind that the diamond core drilling crown could
block at any time. There is a risk of injury from the diamond core drilling machine
being torn out of your hand and spinning round as the torque increases.
NOTICE NOTICE
For dry drilling in concrete/steel-reinforced concrete with REMS Picus DP and
the REMS dry diamond core drilling crowns LS, it is necessary to switch on the
micro-pulse technology and use a suitable safety vacuum cleaner/dust extractor
of dust class M, e.g. REMS Pull M, for dust extraction. For drilling in masonry
and other materials, the micro-pulse technology can be switched off and a
suitable safety vacuum cleaner/dust extractor, e.g. REMS Pull M, must be used.
Observe the national regulations.
Screw the selected REMS dry diamond core drilling crown TDKB LS onto the
drive spindle (11) of the drive unit and lightly hand-tighten. There is no need to
tighten it with an open-ended wrench. Use the G ½ TDKB tapping tool (49)
(see 2.4.1.). Connect a suitable safety vacuum cleaner/dust extractor, e.g.
REMS Pull M, to REMS Picus DP (see 2.4.2.). Switch off the micro-pulse
technology of REMS Picus DP for tapping. To do this, turn the micro-pulse
technology adjusting ring (Fig. 10 (69)) to the detent position so that the red
markings are not in line. Hold the drive unit by the insulated grip surfaces of
the motor handle (20) and the brace (12) and place the G ½ TDKB tapping tool
(49) in the centre of the desired core hole. Switch on the drive unit with safety
inching switch (21).
WARNING WARNING
Never lock the safety inching switch (21) of the drive unit when holding
the drill by hand (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 can only
be brought to a standstill by pulling out the mains plug.
Tap until the diamond core drilling crown has penetrated to a depth of approx.
5 mm.
WARNING WARNING
Pull out the mains plug! Screw out the G ½ TDKB tapping tool (49); loosen
with a size 19 open-ended wrench if necessary. Use a dust extractor (see 2.4.2).
Switch on the micro-pulse technology of REMS Picus DP. To do this, turn the
micro-pulse technology adjusting ring (Fig. 10 (69)) to the detent position so
that the red markings are in line. Continue drilling until the core hole is fi nished.
Always hold the drive unit by the insulated grip surfaces to safely absorb torque
surges (risk of accident!). Make sure that you have a safe footing. Carry out
larger core-drilling operations with a drill stand.
