Maintenance and repair
4.1
Maintenance
Allthough the poker-vibrators type LHF & HS have a few moving parts, regular maintenance
promotes a long and trouble-free life.
Warning!:Do not clean the poker-vibrator with a high pressure cleaner.Disconnect the electrical
supply to the poker-vibrator before you carry out any maintenance activities to the poker-vibrator.
4.2
Cleaning and servicing of the poker-vibrator
During concrete compaction the poker-vibrator, switch and supply cable will become dirty.
Periodical maintenance is vital to the safe and efficient operation of the poker-vibrator.lt is therefor
highly recommended to clean the poker-vibrator daily with water and a cleaning detergent, that
does not affect the poker-vibrator’s material.
When storing the poker-vibrator make sure that the operation hose has been coiled properly, thus
preventing 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.
Tip:
ln case of failure or break down of the poker-vibrator, we advise you to send the machine
to an authorised Lievers/service-station.
Warning!:
We strongly advise you not to carry out repairs to the poker-vibrator by yourself,
without being instructed by the manufacturer or dealer. (read guarantee-provisions)
4.3 Changing the tip of the pokerhead
This paragraph exclusively deals with the replacement of the steel- and rubber tip of the
pokerhead.
1
Lock the rear part of the pokerhead in a vice.
2
File away the welding point where the rear part joints the front part.Loosen the screw thread
by tapping on the tip of the pokerhead with a hammer.
3
Unscrew the tip by means of a hook spanner.(available from the producer).
4
By locking the pokerhead in the vice vertically, you prevent the lubricating oil from running
out of the pokerhead.
5
Before the new tip is installed, the screw thread of the tip,needs to be winded with at least 8
windings of teflon tape.
6
Now tighten the tip by means of the hook spanner and secure it by providing the tip with
a welding point of approx. 5mm. diam.
Careful!: Refill oil if during the above described procedure oil has run out of the
pokerhead. If this special is not available, please contact your dealer or Lievers (Ø36mm-15 cc/
Ø50mm-20cc/Ø57-25cc/Ø65mm-30cc).
