reinforcement.
The electrical motor
has been overloaded,
due to a faulty electrical
supply.

pendulum are dirty, due
to lubrication with oil or
grease.
A break in the feeder
cable.

due to the feeder cable
being too long (longer
than 100m)
Dirt on the inside of the
powerhouse due to
extensive use.
SOLUTION
Prevent the flexible poker vibrator of getting
jammed between the reinforcement. Stop
operation if the poker vibrator gets jammed
after all. Reset - if necessary - the thermical
relay.
Electrical supply via a safety transformer:
check the distributed power from the safety
transformer.
Electrical supply via electrical mains: check
the plug connections for defects. Use an
extension lead of a maximum length of 25 m
with a cross section of 2.5 mm².
Tap against the tip of the pokerhead with a
solid object.
Replace the worn out carbon brushes for
new ones (replace every 6 - 12 months).
Dismantle the pokerhousing, the flexible
drive shaft and the pendulum. Remove the
grease from these parts from the inside of
the pokerhousing thoroughly. After
removing the grease, lubricate the flexible
drive shaft with a special grease, which is
available from the manufacturer.
Check the electrical cable and plug.
Replace the faulty part(s).
Move the electrical source closer to the
working area.
Dismantle the poker housing and the
