Variable Speed Control Models Only - Wyco Sure Speed WVD1 Manual Del Operador Y De Servicio

Insert the vibrator head into the concrete to be
consolidated.
Do not run the vibrator head outside of fresh con-
crete for an extended period of time. The vibrator
depends on moving concrete to cool the bearings.
Avoid sharp bends in the flex shaft during opera-
tion. Sharp bends reduce shaft life.
Remove the vibrator head from concrete and turn
the rocker switch to the "o" (off ) position. (See
Figure 3.0 for switch location.)
