Connecting The Water Supply; Using The Centring Suction Plate (Accessories); Switching On The Wet Diamond Drill And Drilling - Baier Elektrowerkzeuge BDB 819 Translation Of The Original Instruction Manual

5.2

Connecting the water supply

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.
•
10 Connect the water supply (2) with the
coupling (3) to a hose with a Gardena hose
connector (½ inch).
•
10 The water supply can be switched on and
off and finely controlled using the tap (1).
•
Set the water flow rate as low as possible to
avoid the risk of splashing/spraying.
5.3 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 wet diamond core drill
bit diameter must be fitted. The centring suction
plate is available as an accessory (see "Tools and
Accessories" on page 46 or 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 suc-
tion plate is positioned must be flat and imper-
meable to air.
•
11 Select centring disc (2) and rubber sealing
disc (3) according to the diameter of the wet
core drill bit.
•
11 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).
•
12 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 wet diamond
drill and drilling
•
Use the drill for hand-held wet drilling only in
conjunction with the BAIER centring suction
plate (see page 41) and a suitable water
suction appliance (e.g. BAIER special dust
extractor) (see "Tools and Accessories" on page
46 or BAIER catalogue).
•
Before starting up the wet diamond drill, check
all the points described in the "Before starting
work" chapter (see page 39).
•
4 Test the PRCD switch and switch on (see
page 39).
NOTE
Changing gear while the machine is running can
cause damage to the drill.
Wait for the machine to completely stop.
•
5 Set the appropriate speed for the core drill
bit diameter at the gear change knob (1) (see
"Technical specifications" on page 37).
•
13 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 wet
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.
•
14 Press the ON / OFF switch (3) to switch on
the wet diamond drill and wait until the working
speed has been reached – green LED (1) lights
up.
•
10 Open water supply (1) slightly.
