this equipment. Failure to read and understand the Safety
Messages and Operating Instructions could result in injury to
yourself and others.
HAZARD SYMBOLS
NOTE
This Owner's Manual has been developed to provide
complete instructions for the safe and efficient operation
of the STOW VIBRATOR HEADS.
Before using this equipment, ensure that the
operating individual has read and understands all
instructions in this manual.
SAFETY MESSAGE ALERT SYMBOLS
The three (3) Safety Messages shown below will inform you
about potential hazards that could injure you or others. The
Safety Messages specifically address the level of exposure to
the operator, and are preceded by one of three words: DANGER,WARNING, or CAUTION.
Engine exhaust gases contain poisonous
carbon monoxide. This gas is colorless and
odorless, and can cause death if inhaled.
NEVER operate this equipment in a confined
area or enclosed structure that does not
provide ample free flow air.
Explosive Fuel
Gasoline is extremely flammable, and its
vapors can cause an explosion if ignited. DONOT start the engine near spilled fuel or
combustible fluids. DO NOT fill the fuel tank
while the engine is running or hot. DO NOT
overfill tank, since spilled fuel could ignite if it
comes into contact with hot engine parts or
sparks from the ignition system. Store fuel in
approved containers, in well-ventilated areas
and away from sparks and flames. NEVER
use fuel as a cleaning agent.

WARNING!WARNING!
DO NOT attempt to operate this vibrator head
until the Safety and Operating Instructions for
the Electric Motor or Gasoline Power Unit and
Flexible Shaft have been read and fully
understood. Failure to do so could result in
serious bodily injury and/or property damage.
1.The vibrator motor, flexible shafting, and heads are shipped
4.When connecting the head to the casing, clean the mating
threads with an anaerobic sealant primer and allow it to air
dry for several minutes. Apply a ring of anaerobic sealant
(Loctite 271, Hernon 427 or equivalent), to the casing
threads and screw the head tightly to the casing. Wait for
one hour before using.

5.See Compaction Coverage Chart, (Figure 2).
MAKE CERTAIN the motor is disconnected
from the power source and the switch is in the
"OFF" position.
The vibrator head is cooled by the concrete.
Operation of the vibrator head in air longer
than 2 minutes at a time will cause overheating
of the bearings which will result in premature
head failure.
Figure 2. Compaction Coverage
with 50% Radial Overlap
3.To connect the flexible shafting to the vibrator motor see
(Figure 1). (382V Shafting shown)
6.Immerse the head for 5 to 10 seconds, (until air stops rising),
and then withdraw it slowly to let the concrete fill the void
left by the head. The head should be completely below the
surface when vibrating to keep the head cool. When
vibrating a thin horizontal slab, the head can be used in a
horizontal position.
If the shaft begins to helix (buckle) excessively
during operation, stop and investigate. This is
an indication of an overload condition.

CAUTION!CAUTION!
The vibrator heads should be inspected and lubricated after
every 100 hours of use. Refer to (Figure 3).
To Disassemble a Vibrator Head:
1.Remove the flexible shaft from the head. Heat should be
applied to the threads to break down the anaerobic sealant.
This will help prevent possible damage to the threads.
Threads are left-hand.
2.Remove the casing adapter from the housing. Head should
be applied to the threads to break down the anaerobic
sealant. Threads are right-hand. (Ref. 9)
3.Remove the hardened tip from the housing. Heat should
be applied to the threads to break down the anaerobic
sealant. Threads are right-hand. (Ref. 1,12)
DO NOT allow the vibrator head to wear below
the following dimensions: See General
Specifications - page11.
4.Remove the cap screw or hex nut that holds the lower
bearings in place. (Ref. 2)
5.Remove the spindle with the upper bearings still attached.
The lower bearings (tip-end) can now be removed from
the housing.(Ref. 4)
6.Remove and discard the oil seals. Note the way the seals
face so that the new seals will be installed correctly. (Ref. 5)
7.Thoroughly clean all parts with a degreasing solvent and
blow dry with air. Compressed air is not recommended for
cleaning and drying solvents out of the bearings. Bearings
should never be spun at high speed using compressed air.
(Ref. 3)
8.After cleaning, inspect all parts for wear. The bearings
should be checked by applying a light thrust load against
one bearing ring, while slowly rotating the other ring. Do
this in both directions. If any roughness or excessive
looseness is felt, the bearing should be replaced. Any
other parts that show heavy wear should also be replaced
at this time. (Ref. 3)
To Reassemble a Vibrator Head:
6.Apply a high strength anaerobic sealant to the external
threads of the casing adapter. Screw the adapter into the
housing and tighten. Threads are left-hand. (Ref. 1,9)
7.Tip head over and pour in the required amount of Stow
Lube P/N 12000-301. Refer to General Specifications Table
on page 11.
CAUTION!CAUTION!
CAUTION!
CAUTION!CAUTION!
8.Assemble the lower bearings to the spindle. (Ref. 3)
9.Clean the tip threads and the mating threads on the housing
with anaerobic sealant primer. Allow to dry. (Ref. 1,12)
10.Apply a high strength anaerobic sealant to the tip threads
and screw the tip into the housing. Threads are right-hand.
(Ref. 1,12)
Assemble the Head to the Casing:
DO NOT use more than the specified amount
of lubricant in the vibrator head. Over-filling
will cause the head to overheat and lead to
premature failure.
1.Bearing Installation: Bearing installation should take
place under the cleanest possible conditions. Inspect the
spindle bearing seat diameter for nicks and burrs. If any
are found, carefully remove using a stone or fine file. Wipe
the bearing seat diameter with head oil to help prevent
galling while the bearing is being pressed on. While
installing the bearing, the installation force should always
be applied squarely and evenly to the inner race of the
bearing. (Ref. 3)
2.Seal Installation: Remove any nicks or burrs that will
interfere with the installation of the seal. Make sure the
seal is facing the right direction and that it is properly
positioned so that it will seat squarely without damage.
See illustration on page 12. Use an installation tool that
will apply the force evenly around the outer edge of the
seal.
3.Insert the spindle with upper bearings assembled on it,
into the housing. Using a light push fit, seat the bearings
into the housing. (Ref. 4)
4.Insert the seals into the casing adapter per the seal
installation instructions. (See page 12)
11.Clean the casing threads and the mating threads on the
head with an anaerobic sealant primer and allow to dry.
12.Apply a ring of anaerobic high strength sealand to the casing
threads. Screw the casing into the head and tighten.
13.Allow to set one hour before use.
5.Clean the casing adapter external threads and the mating
internal threads on the housing with anaerobic primer and
let dry. (Ref. 1,9)
