Introduction; Operation; Connecting The Vibrator Casing; Disconnecting The Vibrator Casing - Wyco Sure Speed WVD1 Manual Del Operador Y De Servicio

INtroductIoN

The Sure Speed vibrator motor is used to power
concrete flex shaft vibrators which provide vibra-
tion to consolidate freshly poured concrete. The
vibration is created by an eccentric (off center)
weight within the vibrator head. As the weight
spins it forces the head housing to move within the
fresh concrete. The continuous head movement
agitates the concrete mixture resulting in signifi-
cantly reduced voids.
The Sure Speed motor can be used with any valid
Wyco vibrator head and shaft combination. table
1.0 is provided to show the commonly used head
and shaft combinations. Shafts are available in
lengths of 2, 5, 7, 10, 14, and 20 feet.
do not use non-approved parts. The use of non-
approved parts may cause a hazardous condition
for the operator.

nance instructions in this manual. Carefully check
that the power cord has no cuts or exposed wires
and that the vibrator housing is intact.
do not start the motor without a shaft con-
nected. The exposed shaft connection presents a
safety hazard as it rotates at high speed. Clothing or
skin may become entangled in the shaft connection
causing injury.
Ensure that the motor, shaft and head are con-
nected securely as described in the maintenance
instructions.
Ensure that the power plug is connected to the
appropriate power source.
Ensure that the motor is not immersed in concrete
and that any cord connections are not in water or
fresh concrete.
Turn vibrator on by moving the rocker switch to
the "I" (on) position. (See Figure 3.0 for switch
location.)
