WARNING
READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS.
FAILURE TO FOLLOW THE WARNINGS AND
INSTRUCTIONS MAY RESULT IN ELECTRIC SHOCK, FIRE
AND/OR SERIOUS INJURY.
GENERAL POWER TOOL SAFETY
WARNINGS
OTE:NSave all warnings and instructions for
future reference.
OTE:NThe term power tool in the warnings refers to your
mains-operated (corded) power tool or battery-
operated (cordless) power tool.
Work Area Safety
1. Keep work area clean and well lit.
2. Do not operate power tools in explosive atmospheres,
such as in the presence of ammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
3. Keep children and bystanders away while operating a
power tool.
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. Unmodied 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:NThe term residual current device (RCD) may be
replaced by the term ground fault circuit interrupter
(GFCI) or earth leakage circuit breaker (ELCB).
Personal Safety
1. Do not use a power tool while you are tired or under the
inuence of drugs, alcohol or medication to avoid risk of
serious personal injury.
2. Always wear eye protection. Other protective equipment
such as dust mask, non-skid safety shoes, hard hat,
or hearing protection should be used in appropriate
conditions to reduce personal injuries.
3. Make sure the switch is in the OFF position before
connecting to power source and/or battery pack, picking
up or carrying the tool.
4. Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached
to a rotating part of the power tool may result in
personal injury.
5. Do not overreach. Keep proper footing and balance
at all times.
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, make sure these are
connected and properly used. Use of dust collection can
reduce dust-related hazards.
Power Tool Use and Care
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 the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools to reduce the risk of starting the power
tool accidentally.
4. Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool or
these instructions to operate the power tool.
5. Maintain power tools. Check for misalignment or binding
of moving parts, breakage of parts and any other
condition that may aect operation. If damaged, have
the power tool repaired before use.

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 for recommended
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
NON-APPROVED PARTS MAY CAUSE A HAZARDOUS
CONDITION FOR THE OPERATOR.

OPERATION
Before Starting the Motor
DO NOT USE DAMAGED EQUIPMENT. INSPECT
THE VIBRATOR FOR DAMAGE BEFORE 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.
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.
Make sure that the motor, shaft and head are connected
securely. See“Setup” on page 8.
Make sure that the power plug is connected to the
appropriate power source.
Make sure that the motor is not immersed in concrete and
that any cord connections are not in water or fresh concrete.
Operating the Motor
1. Turn vibrator on by moving the rocker switch to I.
OTE:NThe SureSpeed has been designed with a soft start
and will ramp up to speed over a 1 second period.
2. 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 ex shaft during operation.
Sharp bends reduce shaft life.
3. Remove the vibrator head from concrete and turn the
rocker switch to O.

PREVENTIVE MAINTENANCE
Wyco vibrator motors are designed to operate 50…100
hours between normal preventive maintenance intervals.
The service instructions below should be followed to
perform the preventive maintenance.
WARNING
THERE ARE NO USER SERVICEABLE PARTS CONTAINED
WITHIN THE MOTOR HOUSING. OPENING THE MOTOR
HOUSING MAY BE DANGEROUS AND WILL VOID THE
WARRANTY. ANY REPAIRS THAT REQUIRE OPENING
THE MOTOR HOUSING SHOULD BE PERFORMED AT
AN AUTHORIZED WYCO SERVICE CENTER OR AT THE
WYCO FACTORY. USE ONLY FACTORY AUTHORIZED
REPLACEMENTS PARTS.
Brush Removal
For the location of the parts used in the following
procedures see “Parts” on page 11.
1. Disconnect the line cord from the power source.
2. Lay the motor on its side with the brush cap (6) facing up.
3. Use a 1/2 in. 6-sided socket to unscrew the plastic brush
cap (6) from the motor half.
4. The brush spring (5) will pop out. Carefully remove the
brush spring by gently pulling on the spring.
5. Repeat these steps for the opposite side.
Brush Replacement
OTE:NBrushes should be replaced in pairs.
1. Inspect and replace damaged O-rings.
2. Lubricate the O-ring prior to cap installation
3. Align the new brush (5) with brush holder.
4. Insert the new brush.
5. Push the spring into the holder as you screw the brush
cap back into the housing.
OTE:NThe O-ring must be on the brush cap before you
screw the cap into the housing.
6. Torque the brush cap (6) to 35 in. lb.
7. Repeat these steps for the opposite side.
Filter Replacement
1. Pull the old lter down from the housing with
your ngers.
2. Place the new lter (2) in the housing, tapered side up.
See “Parts” on page 11.
ELECTRIC VIBRATOR HEAD
SERVICE AND MAINTENANCE
MPORTANTI
Service the vibrator head after every 50 hours of operation for
trouble-free running on the job.
When servicing, always replace the hex driver, seals and
bearings, or bushing for 750-D & 750-EH heads.
See“Electric Vibrator Head Assembly Drawings and Parts Lists”
on page 16.
All heads are equipped with seals at the flexible shaft end
and contain oil. The seals serve a double purpose; to keep
the oil in the head and to keep the grease from the flexible
shaft out of the head.
1. Hold the nose end in a vise and unscrew the end cap
counterclockwise with a chain wrench or a good pipe
wrench. See Figure 15.
Figure 15: End cap removal
Preventive Maintenance
Page 14 February 2020VBR-UM-02653-EN-05

2. Pull the eccentric rotor assembly out of the housing.
OTE:NIf the bearings are stuck and you have difficulty
removing them from the housing, screw the end
cap partly back into the housing and bounce the
head and cap down on a block of wood in order to
loosen the bearings from their seat, then pull out
the rotor assembly. See Figure 16.
Figure 16: Bearing Removal
OTE:NThe hexagon driver has left hand threads.
3. Flush the rotor assembly and housing with solvent and
wipe all parts clean.
4. Replace bearings, seals and hex driver. Maintain
concentric alignment of the hex driver with respect to
the rotor shaft.
5. Rell with proper amount of Wyco non-foaming vibrator
oil. See Table 2.
6. Apply Loctite 545 adhesive/sealant or equivalent to
threads on both ends of rotor.

Table 2: Head oil requirements
7. Replace the rotor assembly into the head housing.
8. Apply Loctite 545 adhesive/sealant or equivalent all
around the threads of the end cap.
9. Tighten and wipe o excess Loctite 545 adhesive/sealant.
Flexible Shaft Lubrication and Break-in
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.
Lubrication Procedure
To lubricate, lightly coat the core with grease (Wyco shaft
lubricant) while inserting it into the casing.
MPORTANTI
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:
1. Loosen the casing from the motor.
2. Pull out the core about 15…18 in. (318… 457.2 mm).
3. Apply lubricant as above to the exposed section of core.
4. Reinstall the core, making sure that it engages with the
vibrator head. During operation, the grease will travel the
full length of the casing.
Break-in Procedure
A break-in procedure is required after the assembly of
separately shipped core and casing. To break it in, repeatedly
coil 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:NFor 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 3.
