Connecting The Water Supply; Using The Centring Suction Plate (Accessories); Switching On The Wet Diamond Drill And Drilling - Baier BDB 819 Traduction Du Mode D'emploi Original

•
9 Use an open-ended spanner SW36 to hold
the output shaft tight (1).
•
9 Tighten the wet diamond core drill bit (2)
using an open-ended spanner SW41.
•
9 Tighten the wet diamond core drill bit (3)
using an open-end spanner SW22 or SW24.
NOTE
Check the fit and condition of the wet diamond core
drill bit. A damaged wet diamond core drill bit may
not be used and must be replaced immediately.
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 48 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 43) and a suitable water
suction appliance (e.g. BAIER special dust
extractor) (see "Tools and Accessories" on page
48 or BAIER catalogue).
•
Before starting up the wet diamond drill, check
all the points described in the "Before starting
work" chapter (see page 41).
•
4 Test the PRCD switch and switch on (see
page 42).
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 39).
•
13 Align the centring suction plate (1) with the
drill hole and hold tight.
