Wet drilling

•
8 Mount or replace wet diamond drill bit (see
page 41).
•
5 For wet drilling, mount the BAIER wet
adapter (1) (see page 40).
•
Use the drill for hand-held wet drilling only in
conjunction with the BAIER centring suction
plate (see page 44) and a suitable water
suction appliance (e.g. BAIER special dust
extractor - see Tools and Accessories in the
BAIER catalogue).
5.3.1 Connecting the water supply to
the BAIER wet adapter
DANGER
Risk of injury due to electric shock.
Î Protect the machine against splashing water.
When inserting and removing the water hose,
ensure that no water penetrates the air slits of
the machine. Use intact Gardena couplings and
Gardena hose lengths only. Check the sealing
rings for wear or damage. The drill may not be
run with leaking hose couplings.
•
17 Connect the water supply (2) with the
coupling (3) to a hose with a Gardena hose
connector (½ inch).
•
17 The water supply can be switched on and
off and finely controlled using the tap (1).
5.3.2 Using the centring suction
plate (accessories)
Use the drill for hand-held drilling only in
conjunction with the BAIER centring suction plate
and a suitable water suction appliance (e.g. BAIER
special dust extractor). Before using the centring
suction plate, the appropriate rubber sealing
disc and centring disc for the diamond core drill
bit diameter must be fitted. The centring suction
plate is available as an accessory (see Tools and
Accessories in the BAIER catalogue).

WARNING
Risk of injuries due to inadvertent loosening of the
centring suction plate.
Î For long drill holes in the wall or floor, empty
the water suction appliance in-between, as a
full water suction appliance is no longer able to
draw on the centring suction plate tight enough.
Î The base or surface on which the centring
suction plate is positioned must be flat and
impermeable to air.
•
18 Select centring disc (2) and rubber sealing
disc (3) according to the diameter of the wet
core drill bit.
•
18 Screw the rubber sealing disc (3) and
centring disc (2) onto the centring suction
plate (4). Screw materials: 3x hexagon socket
head screw M6 (1), 3x washers M6 (5) and 3x
hexagon nuts M6 (6).
•
19 Push the water suction hose (2) onto the
socket (1).
NOTE
Greater effort may be required to push on the
suction hose in cold ambient temperatures.
5.4 Switching on the diamond drill
and drilling
•
Before starting up the diamond drill, check all
the points described in the "Before starting
work" chapter (see page 39).
•
3 Test the PRCD switch and switch on (see
page 39).
•
20 Align the centring suction plate (1) with the
drill hole and hold tight.
•
Switch the water suction appliance to
continuous operation.
•
Check whether the centring suction plate has
tightly attached itself to the wall or floor.
•
Always hold on tight to both handles of the
diamond drill with two hands.
•
With the wet diamond core drill bit at a standstill,
feed it into the centring suction plate; the wet
diamond core drill bit must not touch the wall
or floor.
NOTE
The ON / OFF switch must not be locked for hand-
held drilling.
