Safety and operating instructions

Maintenance

Regular maintenance is a basic requirement for the
continued safe and efficient use of the machine.
Follow the maintenance instructions carefully.
Before starting maintenance on the machine, clean
it in order to avoid exposure to hazardous
substances. See "Dust and fume hazard".
Use only authorised parts. Any damage or
malfunction caused by the use of unauthorised
parts is not covered by warranty or product liability.
When cleaning mechanical parts with solvent,
comply with appropriate health and safety
regulations and ensure there is satisfactory
ventilation.
For major service of the machine, contact the
nearest authorised workshop.
After each service, check that the machine's
vibration level is normal. If not, contact the nearest
authorised workshop.
The SMART is maintenance free, except for cleaning.
The converter case must be clean to get the best
cooling effect.
NOTICE The unit contains components which have
dangerously high voltages. Wait 2 minutes before
any dismantling is performed.
NOTICE Never use high-pressure water to clean
the drive unit.
Tripping of residual current device (RCD):
1. Inspect cable and plug, replace any damaged or
defective parts.
2. If the problem remains, replace the converter.
Problem with the converter:
1. Press the switch to stop the converter.
2. Wait 30 seconds.
3. Press the switch to start the converter. If the
converter started again, it was overloaded due
to a defective mechanical part or the poker got
stuck in the steel reinforcement.

1. With the machine unplugged and power
removed, short circuit between phases on the
poker side:
Disconnect the wires from the converter to the
vibrating head. Measure the resistance between
phases on poker side. Compare the values with
those stated on the poker with the table, see
below. If the values are incorrect, inspect the
wiring and the tube stator. Replace the defective
part.
2. Short circuit between phases and ground (earth):
Measure the resistance between each phase
and the ground (earth). If the resistance is 10
Mega ohms or less, inspect the wiring and the
stator tube. Replace the defective part.
3. Overload:
Raise the poker from the concrete, measure the
input current to the poker (see the table below
for maximum values). The measurements are
taken after two minutes. If the measured values
do not correspond with the values stated in the
table, dismantle the vibrator tube and check the
mechanical parts. Replace the defective part. If
the mechanical parts are correct, there is an
overload in the converter. Check the input current
to the poker when the poker is immersed in the
concrete. Make sure that the current does not
permanently exceed the ampere stated on the
data plate.
4. Overheating: temperature of the converter casing
is >60°C (140°F).
This could be caused by overload or too high
ambient temperature.
Wait until the temperature of the casing has
decreased by 10°C (50°F), then press the
ON/OFF switch.
