5.2 Cleaning and servicing of the hand held poker vibrator
During concrete compaction the poker vibrator, hand grip, PRCD and supply cable will become dirty.
Periodical maintenance is vital to the safe and efficient operation of the poker vibrator. It is, therefore,
highly recommended to clean the poker vibrator daily with water and a cleaning detergent which
does not affect material of the poker vibrator. The hand grip should be cleaned with a damp cloth.
When storing the poker vibrator make sure that the operation hose does not kink, in order to prevent cuts and
cracks to the rubber hose.
If the poker vibrator is to be stored for a long period of time, it should be put on an appropriate stand and left to
hang.
