DI-switch (in-line protector PRCD)
(Fig. 1)
The machine is equipped with a portable residual
current device (PRCD) (i), which protects the user
against electric shock by interrupting the circuit
when a leakage current of 10 mA or greater is
detected.
WARNING: Never operate the machine
without the PRCD in place. Do not
use the machine if the PRCD does not
function properly. For the PRCD to work,
the machine must be connected to an
earthed wall socket.
TO SWITCH ON THE RCD
I = ON (red LED lights up).
Switch on the machine (also refer to the section
Switching On and Off).
To switch off, proceed in reverse order.
TO TEST THE RCD
O = Test button: the switch must break the circuit
(machine switches off).
WARNING:
• If in the test mode the switch does not
break the circuit, we recommend that
the unit is inspected by an authorized
WALT repair agent.
D
E
• It is not permitted to make any
modifications to the machine, in
particular it is not allowed to open
the PRCD or to repair or replace the
cable.
• Never use the PRCD as a main
switch. Always switch the PRCD
under no load condition.
ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of
injury, turn unit off and disconnect
machine from power source before
installing and removing accessories,
before adjusting or changing set-
ups or when making repairs. Be sure
the trigger switch is in the OFF position.
An accidental start-up can cause injury.
Fitting the Side Handle (Fig. 3)
The side handle (e) can be fitted to suit both
RH- and LH-users.
WARNING: Always use the tool with
the side handle properly assembled.
1. Twist the side handle to loosen it.
2. For RH-users, slide the side handle clamp over
the collar, handle at the left.
For LH-users, slide the side handle clamp over
the collar, handle at the right.
3. Rotate the side handle to the desired position
and tighten the handle.
MOUNTING AND REMOVING AN ACCESSORY (FIG. 4)
This tool uses threaded core bits and adaptors
which thread directly onto the spindle (d).
We recommend to use professional accessories
only.
1. Choose the appropriate core bit for wet or dry
drilling.
2. Follow the core bit or manufacturer's
recommendations for mounting the accessory.
You may require an adaptor to fit the bit onto
the spindle.
3. Hold the spindle using the open-ended
wrench (o) and tighten the core bit (p) by
rotating clockwise using the open-ended
wrench (q).
WARNING: Make sure the entire
assembly is tight before starting the
operation.
Three Gear Selector (Fig. 1)
The tool is fitted with a three gear selector (f) to vary
the speed/torque ratio.
1. Release the switch and select the required
position after the motor has come to a
complete standstill.
2. Always align the selector with the marks on the
gear housing.
3. Refer to the technical data to choose the
appropriate gear according to the diameter of
the core bit and the material to be drilled.
4. Do not change gears at full speed or
during use.
Connecting to a Water Supply (Fig. 5)
These tools have a standard 1/2" bayonet fitting for
the water supply fitting (g).
1. Screw the adaptor (r) onto the fitting (g) and
tighten firmly.
2. Close the water tap (s).
3. Connect an appropriate water supply system to
the adaptor.
WARNING: Make sure that the
pressure of the water supply is below
the max. pressure as stated in the
technical data.
