2.3.1. Fitting the diamond core drilling crown
WARNING
Unplug from the mains power supply! Screw the selected diamond core
drilling crown onto the drive spindle (11) of the drive unit, and lightly hand-tighten.
It is an advantage to insert the quick-release ring (54) (art. no. 180015) between
the diamond core drill crown and the drive spindle. Firm tightening with an
open-ended wrench is not necessary. Note that the threads on the drive spindle
and diamond core drilling crown must be clean.
2.3.2. Removing the diamond core drilling crown
WARNING
Unplug from the mains power supply! Use an SW 32 wrench to hold the
drive spindle (11) and an SW 41 wrench to loosen the diamond core drilling
crown (48).
Always unscrew the diamond core drilling crown from the drive unit when the
drilling task is finished. With wet-drilling operations in particular, t here is also
a danger of the diamond core drilling crown becoming corroded, making it
difficult to remove.
NOTICE
The casing pipes of the diamond core drilling crown are not hardened. Hitting
(with tools) and impact (during transport) on the casing pipe will lead to damage
that is likely cause the diamond core drilling crown and/or drilling core to become
seized. The diamond core drilling crown may then be rendered unusable.
2.3.3. Sharpening the diamond core drilling crown
REMS Universal diamond core drilling crowns have roof-shaped diamond
segments and do not have to be sharpened in the as-delivered state. At the
right thrust pressure and possibly by adding water, the diamond segments
sharpen themselves. Unsuitable thrust pressure as well as dry drilling in concrete
leads to the diamond segments being "polished" and no longer being able to
cut. If this occurs, use the diamond core drilling crown to drill 10 mm to 15 mm
into sandstone, asphalt or a sharpening stone (55) (accessory art. no. 079012)
in order to sharpen the diamond-tipped segments once more.
2.4. Manually-controlled dry boring REMS Picus S1, REMS Picus S3 and REMS
Picus SR (fig. 4)
Secure the holder-up (12) to the drill collar (13) of the drive unit.
WARNING
Only use the tool held by hand with the brace (12) fitted (danger of injury)!
Never perform hand-held dry drilling with REMS Picus SR in stage 1. The
resulting high torque can lead to injury.
Inhalation of the dusts produced by dry drilling is harmful to the health. Observe
the national regulations. It is recommended to use the suction rotor (46) (acces-
sory, part no. 180160) and a safety vacuum cleaner/dust extractor of dust class
M e.g. REMS Pull M (Art. No. 185501) with suitable filter (observe the operating
instructions of the safety vacuum cleaner/dust extractor).
CAUTION
The water supply system (15) gets in the way of manually-controlled dry boring,
and it should therefore be disconnected. Remember to shut off the water inlet
with its sealing cap (14) to prevent dust from getting into the machine.
NOTICE
Always wet drilling for steel-reinforced concrete!
2.4.1. Tapping tool for REMS Picus S1, Picus S3 and Picus SR
Manually-controlled tapping is made considerably easier, thanks to the REMS
tapping tool (49). This is fitted with a conventional hardened- m etal Ø 8 mm
masonry bit, which is secured in place with an SW 3 hexa gon socket head
wrench. The G ½ thread is used to screw the tapping tool into the spindle of
the drive unit, where it is gently tightened with an SW 19 wrench.
2.4.2. Dust extraction REMS Picus S1, REMS Picus S3 and REMS Picus SR
(fig. 4)
WARNING
Inhalation of the dusts produced by dry drilling is harmful to the health. Observe
the national regulations. It is recommended to use a dust extractor to remove
drilling dust from the core bore. This consists of the REMS suction rotor (46)
(Art. No. 180160) for dust extraction and safety vacuum cleaner/dust extractor
of dust class M suitable for commercial use, e.g. REMS Pull M (Art. No. 185501).
Observe the operating instructions of the safety vacuum cleaner/dust extractor.
The suction rotor (46) is screwed to the drive spindle (11) of the drive unit using
the G ½ connector. The combined annular core bit connector (47) on the
opposite side permits the fitting of diamond core drilling crowns with female
thread UNC 1¼ and the attachment of the tapping tool (49).
NOTICE
Always wet drilling for steel-reinforced concrete!
If the dust produced by dry boring is not removed, the diamond core drilling
crown may overheat and suffer damage. There is also a risk of injury when the
drilling dust compressed in the gap blocks the diamond core drilling crown.
2.5. Wet boring
Optimum drilling performance will only be achieved if the diamond c ore drilling
crown is provided with a constant supply of water. This keeps the diamond core
drilling crown cool and allows drilled-out material to be swilled from the bore
20
hole. To connect the water supply system (15), remove the cover (14) and
attach the water supply system with the fillister head screw supplied. The
quick-action coupling with w ater shutoff device should be fitted with a ½" water
hose. Water pressure should not exceed 4 bar.
If there is no direct water connection available, water throughflow can be
achieved using the water pressure tank (51) (Art. No. 182006). Be aware that
there is sufficient water flow.
When drilling with REMS Titan or REMS Simplex 2 the water extractor (44)
(Art. No. 183606) can be used. See Fig. 10 and 11 for assembly. This consists
of a water collecting ring, a pressure ring and a rubber washer. The water
extractor is fixed to the base of the drilling column (1). The water collecting ring
is connected to a wet vacuum cleaner suitable for commercial use, e.g. REMS
Pull L or REMS Pull M. The rubber washer (45) must be cut out exactly to fit
the diameter of the diamond core drilling crown.
2.6. Boring with a drill upright
Good results can be obtained by operating with a drill upright. The purpose of
the drill upright is to guide the drive unit. Its power transfer rack-and-pinion
drive system ensures both hole-tapping with „feel" and powerful infeed of the
diamond core drilling crown. REMS Picus S1, REMS Picus S3 and REMS Picus
SR can be mounted optionally on the REMS Simplex 2 or REMS Titan drill
stands. REMS Picus S2/3,5 must be mounted on REMS Titan.
In REMS Titan the clamping angle (10) or the REMS Picus S2/3.5 must be
mounted. The clamping angle (10) or the REMS Picus S2/3.5 must be inserted
in the guide (53) and fastened with the screws (52) for this.
The boring trestle (1) of REMS Titan is infinitely adjustable up to 45°. This allows
angled core drilling operations to be carried out within this angle range. The
degree marks on the struts (40) serve for orientation. To adjust the angle, the
two hexagon head screws (31) at the foot of the boring trestle (1) are removed.
The hexagon head screw (37) and all the screws on the two struts must be
loosened. The boring trestle can now be swivelled to the desired position.
Retighten all screws before proceeding. The screws (31) are not installed to
produce the angled core drilling operation(s). The swivel adjustment of the
boring trestle causes the useful stroke range of the feed device of the REMS
Titan to decrease more or less. This means that you may have to use corre-
sponding annular bit extensions (see 3.7).
The feed slide (2) can be locked on the drill stands. Tighten the wing nut (32)
for this. Locking prevents such undesired movements as the accidental lowering
of the drive unit while the diamond core drilling crown is being replaced.
On all drill stands the feed lever (4) can be fitted to the right or left of the feed
slider (2) according to local conditions (not preassembled in the as-delivered
state of REMS Simplex 2). Lock the feed slider as described above for this.
Unscrew the fillister head screw (34). Pull the feed lever off the feed shaft and
push it onto the shaft stump opposite. Screw in and tighten the fillister head
screw (34).
To achieve better stability when drilling with REMS Titan and REMS Picus SR,
the spacer set (38, accessory art. no. 183632) can be mounted. For this, the
clamping angle (10) may have to be disassembled from the REMS Titan by
loosening the screws (52). Then clamping angle (10) is pushed onto the drill
collar (13) of the REMS Picus SR so that the tapped holes (60) of the gearbox
casing of Picus SR are positioned in relation to the screw holes of the clamping
angle (10). Insert the spacer (without fillister head screws) and align. Screw in
the fillister head screws included in the set and tighten. Tighten the fillister head
screws (8) of the clamping angle (10). Fix the mounted clamping bracket together
with Picus SR to the REMS Titan as described in 3.4.
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, Art. No.
183604) is inserted into the clamping bracket (10) and tightened with the fillister
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 fixed 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).
