3.5. Wet-boring with drill upright
REMS Picus S1 und 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.
Connect the water supply (see 2.5.). 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, and
– with the water supply at a minimum – carefully tap the drill hole. Once
the annular bit has engaged all-round, the feed rate can be increased.
Adjust the water pressure 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. Ensure that no water is allowed
to get into the drive unit motor during operation. DANGER OF FATAL
ACCIDENT!
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 repeated several
times in succession, prevents damage to the drive unit. If the motor re-
mains 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!
3.6. Removal of the drilling core
Important: When carrying out vertical drilling, e.g. in a ceiling, note that
the drilling core normally drops out as soon as the hole is complete! Take
appropriate steps to ensure that personal injury or material damage does
not result.
If the drilling core remains hanging in the diamond core drilling crown
after the core-drilling operation is complete, the bit must be unscrewed
from the drive unit and the drilling core knocked out with a rod.
Important: NEVER hit the casing of the drilling core with a metal item
such as a hammer or wrench in order to loosen the drilling core. This
will cause the casing pipe to become dented, which will make blocking
of the drilling core even more likely on future occasions. The diamond
core drilling crown may then be rendered unusable.
If the core-drilling operation does not penetrate fully, the drilling core can
be broken up, down to a depth of 1.5 x Ø, by inserting a tool such as a
chisel into the drilling gap. If the drilling core cannot be secured, use a
tool such as a hammer drill to make an angled hole into the drilling core,
and insert a rod to extract it.
3.7. Extending the diamond core drilling crown
If the stroke distance of the drill upright, or the useful drilling depth of the
diamond core drilling crown, is insufficient, an annular-bit extension (avai-
lable as an accessory) should be used. Start by drilling in as far as pos-
sible in the normal way.
If the stroke distance of the drill upright, and boring depth within the
usable boring depth of the diamond core drilling crown, are insufficient,
proceed as follows:
Unplug from the mains power supply. Do not pull the diamond core dril-
ling crown out of the core-drilling hole. Detach the diamond core drilling
crown from the drive unit (see 2.3.2.). Turn back the drive unit without
the diamond core drilling crown. Fit the annular-bit extension (50) bet-
ween the diamond core drilling crown and drive unit.
If the usable drilling depth of the diamond-tipped annular core is insuf-
ficient, proceed as follows:
Unplug from the mains power supply. Detach the diamond core drilling
crown from the drive unit (see 2.3.2.). Turn back the drive unit without
the diamond core drilling crown. Pull the diamond core drilling crown out
of the core-drilling hole. Break up the drilling core (see 3.6.), and remove
it from the core-drilling hole. Reinsert the diamond core drilling crown
into the hole. Fit the annular-bit extension (50) between the diamond
core drilling crown and drive unit.
4. Maintenance
Always disconnect at the mains plug before carrying out servicing or
repair work.
4.1. Maintenance
Carry out regular checks of the PRCD fault-current safety switch (see
3.). Keep the drive unit and handles clean. When the drilling operation
is complete, clean the drill upright and annular bit with water. Blow out
the ventilation opening of the motor from time to time with a compres-
sed-air hose. Keep the crown connection thread on the drive unit and
the connection thread on the diamond core drilling crown clean and
apply oil from time to time.
4.2. Inspection/Maintenance
Always unplug the unit from the mains supply before carrying out main-
tenance work. These tasks must be carried out by properly qualified or
suitably trained persons.
The motors of the REMS Picus S1, REMS Picus S3 and REMS Picus
S2/3,5 are fitted with carbon brushes. These are subject to wear, and
must be checked at regular intervals and replaced as required. We re-
commend having the drive units inspected and maintained after every
250 operating hours, or at least once a year, by an authorised REMS
customer service provider.
This is independent of any local rules that may apply with respect to the
operation of electrical equipment on construction sites.
5. Troubleshooting
Important: DO NOT switch the drive unit on and off in an attempt to free
a blocked diamond core drilling crown.
5.1. Fault: diamond core drilling crown jams.
Cause: Possibly caused by compressed drilling dust resulting from
dry-boring without a dust extraction system.
Remedy: Switch off drive unit. Use an SW 41 wrench to turn the dia-
mond core drilling crown back and forth in order to free it.
Carefully continue the drilling operation. Use a dust extrac-
tion system, or wet-boring.
5.2. Fault: diamond core drilling crown jams or cuts only with difficulty.
Cause: Loose material or metal debris have jammed up the mecha-
nism.
Remedy: Break up the drilling core and remove loose items.
Cause: Casing pipe is out-of-true or damaged.
Remedy: Use a new diamond core drilling crown.
5.3. Fault: diamond core drilling crown cuts with difficulty.
Cause: Incorrect turning speed (REMS Picus S3, REMS Picus S2/3,5).
Polished diamond-tipped segments.
