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 remains stopped despite the reduction in feed
pressure, the drive unit must be shut down and the diamond core drilling crown
freed manually (see 5.).

REMS Picus S2/3,5
Fix the REMS Titan in one of the ways described in 3.3. Loosen the two screws
(52) on the fl ange of the REMS Titan, insert REMS Picus S2/3.5 in the guide
(53). Hold the drive unit and tighten the screws (52) Tighten the lock nut. Screw
the selected diamond core drilling crown onto the drive spindle (11) of the drive
unit and tighten by hand with a slight swing. Tightening with an open-ended
wrench is not necessary.
Connect the water supply (see 2.5.). Switch on the drive unit with the rocker
switch (21a). Hold the diamond core drilling crown by the insulated grip surfaces,
move forward slowly with the feed lever (4) and start tapping carefully with a
low water supply. The feed can be increased once the diamond core drilling
crown has engaged all round. Set the water pressure so that a moderate but
constant supply of water emerges from the bore hole. Too low water pressure at
which the removed material emerges rather muddily from the bore hole is ,just
as much a disadvantage for the progress of work and useful life of the diamond
core drilling crown as too high water pressure at which the fl ushing water emerges
clearly from the bore hole. Suck up the drilling water preferably with a suitable
dry and wet vacuum cleaner, e.g. REMS Pull L or REMS Pull M.
WARNING
WARNING
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 remains stopped despite the reduction in feed
pressure, the drive unit must be shut down and the diamond core drilling crown
freed manually (see 5.).

3.6 Removal of the drilling core
NOTICE
NOTICE
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.
NOTICE
NOTICE
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 insuffi cient, an annular-bit extension ((50) accessory art.
no. 180155) should be used. Start by drilling in as far as possible in the normal
way.
If the stroke distance of the drill upright, and boring depth within the usa ble
boring depth of the diamond core drilling crown, are insuffi cient, proceed as
follows:

WARNING
Unplug from the mains power supply!
Do not pull the diamond core drilling
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 exten sion ((50) accessory art. no. 180155)
between the diamond core drilling crown and drive unit.
If the usable drilling depth of the diamond-tipped annular core is insuffi cient,
proceed as follows:
WARNING
WARNING
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) accessory art. no. 180155) between the diamond
core drilling crown and drive unit.
4 Maintenance
Notwithstanding the maintenance described below, it is recommended to send
in the power tool to an authorised REMS contract customer service workshop
for inspection and periodic testing of electrical devices at least once a year. In
Germany, such periodic testing of electrical devices should be performed in
accordance with DIN VDE 0701-0702 and also prescribed for mobile electrical
equipment according to the accident prevention rules DGUV, regulation 3
"Electrical Systems and Equipment". In addition, the respective national safety
provisions, rules and regulations valid for the application site must be considered
and observed.
4.1 Maintenance
WARNING
WARNING
Pull out the mains plug before maintenance work!
Check the function of the PRCD fault current circuit breaker regularly (see 2.1.).
Keep the drive unit and handles clean. Clean the drill stand and diamond core
drilling crown with water after fi nishing the drilling work. Blow out the air vents
on the motor from time to time. Keep the drilling crown connecting thread on
the drive unit and the connecting thread of the diamond core drilling crown
clean and oil from time to time. Clean plastic parts (e.g. housing) only with
REMS CleanM machine cleaner (Art. No. 140119) or a mild soap and a damp
cloth. Do not use household cleaners. These often contain chemicals which
can damage the plastic parts. Never use petrol, turpentine, thinner or similar
products for cleaning.
Make sure that liquids never get onto or inside the electric diamond core drilling
machine. Never immerse the electric diamond core drilling machine in liquid.
4.2 Inspection/Maintenance
WARNING
WARNING
Pull out the mains plug before maintenance and repair work!
This work
may only be performed by qualifi ed personnel.
The gear runs in a life-long grease fi lling and therefore needs no lubrication.
The motors of REMS Picus S1, REMS Picus S3, REMS Picus S2/3.5, REMS
Picus SR and REMS Picus DP have carbon brushes. These are subject to
wear and must therefore by checked and changed by qualifi ed specialists or
an authorised REMS customer service workshop from time to time.
5 Faults
NOTICE
NOTICE
Do not switch the drive unit on and off to loosen a jammed diamond core drilling crown!
5.1 Fault:
Diamond core drilling crown jammed.
Cause:
Remedy:
● Compressed drilling dust in dry drilling without dust extraction.
● Switch off the drive unit. Pull out the mains plug. Move the diamond core
drilling crown to and fro with a size 41 open-ended wrench until it is freed
again. Continue drilling carefully. Use a dust extractor or drill wet with REMS
Picus S1, REMS Picus S3, REMS Picus S2/3.5 and REMS Picus SR.
