Electrical Safety; Start-Up; Setting Up The Machine; Switching On And Off - Lescha SM 145 S Notice Originale

• Do not reach into mixer when it is
running (
rotating mixing apparatus).
Observe enough safety distance to the
concrete mixer. Prevent any contact to rotating or moving
parts of the machine.
• Fill or empty the mixing drum only when the motor is running.
• Observe the mixer's direction of rotation.
• Do not alter the revolution speed of the motor, since this
controls the safe maximum operating speed, and protects the
motor and all rotating parts against damage due to excess
speed.
• Concrete mixers which the manufacturer has not intended for
towed vehicle operation may only be run by means of a hand
wire pull.
• Be absolutely sure to pull the plug before:
− moving or transport
− cleaning, maintenance or repair work
− eliminating faults
− checking connecting lines, whether these are knotted or
damaged
− leaving unattended (even during short interruptions)
• Check the machine for possible damage:
Before further use of the machine the safety devices must
−
be checked carefully for their proper and intended
function.
Check whether movable parts function perfectly and do
−
not stick or whether parts are damaged. All parts must be
correctly installed and fulfil all conditions to ensure perfect
operation of the machine.
Damaged safety devices and parts must be properly
−
repaired or exchanged by a recognized, specialist
workshop; insofar as nothing else is stated in the
instructions for use.
Damaged or illegible safety labels have to be replaced.
−
• Store unused equipment in a dry, locked place out of the
reach of children.
Shockproof concrete mixers
(Protection Class II)
• Only start the machine when the panelling is complete and
fully closed.
• Protection Class II applies only if original insulating material
is used for repairs and insulation clearances are not altered.

Electrical safety

Danger to life and limb if not observed!
• Connecting attachments must be designed in conformance
with IEC 60245-4 and marked H 07 RN-F, or comparable
models. Cross section of wires at least 3 x 1.5 mm² up to a
maximum length of 25 m. Wire cross-section at least 2.5 mm²
for lengths of more than 25 m.
• Use only connecting attachments with a rubber plug device
for severe requirements
spraying water.
• Long and thin connection lines result in a potential drop.
The motor does not reach any longer its maximal power;
the function of the device is reduced.
• Unwind the cable completely when using a cable drum.
that is protected against
• Do not use the power cords for purposes they are not
intended for. Protect the cable against heat, oil and sharp
edges. Do jerk on the power cable when pulling the plug from
the socket.
• Check connecting attachments for defects or ageing before
using them.
• Never use defective connecting attachments.
• When laying the connecting attachments, be sure that they
do get crushed or bent, and that the plug-and-socket
connection does not get wet.
• Do not use any provisional electrical connections.
• Never bridge over protective devices or put them out of
operation.
• Only hook up the machine by means of a
fault-current circuit breacker: 30 mA!
A licensed professional electrician must make all electrical
connections and repairs, and observe local regulations in
doing so, especially those regarding protective measures.
The manufacturer or a company designated by the
manufacturer must attend to the repair of all electrical
parts on the machine.
Use only original spare. Accidents can arise for the user
through the use of other spare parts. The manufacturer is
not liable for any damage or injury resulting from such
action.

Start-up

Observe all safety instructions.

Setting up the machine:

• Set up and run the concrete mixer on a
solid, level base only (where it will not tip over).
• Keep the machine from sinking into the ground or floor.
Adhere to accident prevention regulations (danger of
tipping).
• When setting up the machine, make sure that the mixing
drum can be emptied without obstruction.

Switching on and off

Be sure that
− all protective devices are on the mixer and properly mounted.
− all safety instructions are adhered to.
• The on/off switch is located beneath
the motor housing. Switch the motor
on and off only at the switch.
• In the event of a power failure, the
machine will switch off automatically.
Press the switch again to restart the
machine.

Motor protection


The motor is equipped with a thermostat. The thermostat
switches the motor off automatically in the event of overload
(overheating). The machine can be restarted after a cooling-off
period.
