6. Do not wear loose clothing or jewelry. Keep your
hair, clothing and gloves away from moving parts.
Loose clothes, jewelry or long hair can be caught in
moving parts.
7. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection can
reduce dust-related hazards.
Power Tool Use and Care
Electrical Safety
1. Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed or grounded power tools. Unmodied plugs and
matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges, and refrigerators. There is
an increased risk of electric shock if your body is earthed
or grounded.
3. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
4. Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
5. When operating a power tool outdoors, use an extension
cord suitable for outdoor use to reduce the risk of
electric shock.
6. If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply to reduce the risk of electric shock.
OTE:N The term residual current device (RCD) may be
replaced by the term ground fault circuit interrupter
(GFCI) or earth leakage circuit breaker (ELCB).
1. Do not force the power tool. Use the correct power tool
for your application.
2. Do not use the power tool if the switch does not turn it
on and o. Any power tool that cannot be controlled with

Additional Safety Note
Double insulated tools are equipped with a polarized plug
(one blade is wider than the other). This plug will fit in a
polarized outlet only one way. If the plug does not fit fully
in the outlet, reverse the plug. If it still does not fit, contact
a qualified electrician to install a polarized outlet. Do not
change the plug in any way. Double insulation eliminates the
need for the three-wire grounded power cord and grounded
power supply system.
INTRODUCTION
This concrete vibrator motor is used to power concrete flex
shaft vibrators which provide vibration 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 significantly reduced voids.
This motor can be used with any valid Wyco vibrator
head and shaft combination. See Table 1: Head and shaft
combinations on page 6 or common combinations. Shafts
are available in lengths of 2, 5, 7, 10, 14, 20 and 30 feet (0.61,
1.52, 2.13, 3.05, 4.27, 6.1, and 9.14 m).
WARNING
DO NOT USE NON-APPROVED PARTS. THE USE OF NONAPPROVED PARTS MAY CAUSE A HAZARDOUS CONDITION
FOR THE OPERATOR.

OPERATION
Before Starting the Motor
DANGER
DO NOT USE DAMAGED EQUIPMENT. INSPECT THE
VIBRATOR FOR DAMAGE PRIOR TO USING THIS
EQUIPMENT. READ, UNDERSTAND AND FOLLOW ALL
SAFETY AND MAINTENANCE INSTRUCTIONS IN THIS
MANUAL. CAREFULLY CHECK THAT THE POWER CORD
HAS NO CUTS OR EXPOSED WIRES. VERIFY MOTOR
HOUSING IS INTACT. CHECK ALL ACORN NUTS TO VERIFY
THEY ARE TIGHTENED.
DANGER
DO NOT START THE MOTOR WITHOUT A SHAFT
CONNECTED. 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 connected
securely. See Preventive Maintenance on page 12.
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 I. See
Table 3: Concrete vibrator replacement parts on page 12 for
switch location.
OTE:N The Sure Speed has been designed with a soft
start and will slowly ramp up to speed over a 1
second period.
Insert the vibrator head into the concrete to be consolidated.
Do not run the vibrator head outside of fresh concrete for an
extended period of time. The vibrator depends on moving
concrete to cool the bearings.
Avoid sharp bends in the flex shaft during operation. Sharp
bends reduce shaft life.
Remove the vibrator head from concrete and turn the rocker
switch to O. See Table 3: Concrete vibrator replacement parts
on page 12 for switch location.
Variable Speed Control Models Only
The variable speed option allows the operator to choose
between 8000, 10,500, and 12,000 VPM (vibrations
per minute).
OTE:N This instruction only pertains to model numbers that
start with WV.
OTE:N See “Concrete vibrator replacement parts” on page
12 for switch and button locations.
When the power switch is turned on, the motor will always
start at 10,500 VPM. From the time the power is applied
there is a 20 second window in which to choose one of the
alternate motor speeds.

wipe all parts clean. Replace bearings, seals and hex
driver. Maintain concentric alignment of the hex driver
with respect to the rotor shaft. Rell with proper amount
of Wyco No. 514-O non-foaming vibrator oil. See Table
4. Apply Loctite 545 adhesive/sealant or equivalent to
threads on both ends of rotor.

Flexible Shaft Lubrication Procedure
When vibrators are shipped completely assembled from the
factory, the shafts are lubricated and broken-in. If separate
cores and casings are shipped, they require the following
lubrication and break-in procedure. Core and casing
combinations should be checked for lubricant levels at least
every 50 hours.
To lubricate, lightly coat the core with grease (Wyco 514-B
shaft lubricant) while inserting it into the casing. Do not
over lubricate. Surplus lubricant may get past the seal in
the vibrator head. Over lubrication will also increase the
amount of torque required to operate the vibrator, resulting
in additional stress on the motor and possibly early core and
casing failure.
When adding lubricant on the job, after each 50 hours of
operation, loosen the casing from the motor and pull out the
core about 15…18 inches (318.... 457.2 mm). Apply lubricant
as above to the exposed section of core. Reinstall the core,
making sure that it engages with the vibrator head. During
operation, the grease will travel the full length of the casing.
A break-in procedure is required after the assembly of
separately shipped core and casing. This procedure involves
repeatedly coiling the flex shaft from the head to the motor
while the motor is running. The coiling and uncoiling should
be repeated at least three times for proper break-in.
OTE:N For shorter core and casing combinations, coiling
is not possible. Break-in for short core and casings
requires bending into a U-shape instead of a coil.
Water is one of the greatest enemies of satisfactory
performance of vibrator heads. As the head is submerged in
the mix, water and cement can infiltrate into the head unless
precautions are taken. In addition to securely tightening the
head onto the flexible shaft, the threads on the head and
shaft must be coated with Permatex Form-A-Gasket No.
2. This must be done each and every time that the head is
removed and reinstalled.

Extension Cords
When selecting an extension cord for use with Wyco electric motor cord sets using a three-prong polarized plug, an
equivalent plug set must be used for the grounded or earthed version.
MPORTANTI
A grounded or earthed motor requires a grounded or earthed extension cord.
A two-prong extension cord may be used for the double insulated motor. Extension cords must be approved for outdoor use
and the wire gauge of the cord must be appropriate for the expected load. See Table 5.
