STOW MS-93 MIXER — OPERATION MANUAL — REV. #5 (03/26/10) — PAGE 11

STOW MS-93 PLASTER/MORTAR MIXER — TOWING GUIDELINES

Towing Safety Precautions

CAUTION

To reduce the possibility of an accident while transport­ing the mixer on public roads, always make sure that the
mixer towing components and the towing vehicle are in
good operating condition and both units are mechani­cally sound.

The following list of suggestions should be used when tow­ing the mixer:

■ Check with your county or state safety towing regulations

department before towing your mixer.

■ Make sure that the hitch and coupling of the towing vehicle

are rated equal to, or greater than the trailer "gross vehicle
weight rating" (GVWR).

■ ALWAYS inspect the hitch and coupling for wear. NEVER

tow the mixer with defective hitches, couplings, chains
etc.

■ CHECK the tire air pressure on both the towing vehicle

and the trailer. Also check the tire tread wear on both
vehicles.

■ ALWAYS make sure the mixer is equipped with a "Safety

Chain".

■ ALWAYS attach trailer's safety chain to the frame of tow-

ing vehicle.

■ ALWAYS make sure that the towing vehicle's directional,

backup, and brake lights are working properly.

■ Remember in most cases the maximum speed unless

otherwise posted for highway towing is 55 MPH, however
before towing your mixer, check your local state, and
county vehicle towing requirements. Recommended
off-road towing is not to exceed 10 or 15 MPH or less
depending on type of terrain.

■ Place chocked blocks underneath wheels to prevent roll-

ing, while parked, if disconnected from towing vehicle.

■ Inflate tires to correct pressure, inspect tires for cuts, and

excessive wear. See Table 9 (Tire Wear Troubleshooting).

■ When towing of the mixer is required, place the drum in

the up position (mouth facing upwards) and lock the drum
latch.

Regularly Inspect

Towing Components

■ ALWAYS make sure that the fuel valve lever is in the OFF

position (gasoline models only).

■ Check wheel mounting lug nuts with a torque wrench.

Torque wheel lug nuts as described in the maintenance
section of this manual.

■ Check tightness of U-clamp nuts, torque suspension

hardware as referenced in the maintenance section of
this manual.

■ Avoid sudden stops and starts. This can cause skidding,

or jackknifing. Smooth, gradual starts and stops will
improve gas milage.

■ Avoid sharp turns to prevent rolling.

Tow Bar to Vehicle Connection (Coupler Only)

1. Check the vehicle hitch ball, and mixer's coupler for signs
of wear or damage. Replace any parts that are worn or
damaged before towing.

CAUTION

If the mixer tow bar is deformed or damaged, replace the
entire tow bar. NEVER tow the mixer with a defective tow
bar. There exists the possibility of the mixer separating
from the towing vehicle.

2. Use only a 2-inch ball diameter (towing vehicle), this will
match the mixer's 2-inch coupler. Use of any other ball
diameter will create an extremely dangerous condition
which can result in separation of the coupler and ball or
ball failure.

3. After tow bar has been connected to mixer (see next
page), attach mixer's coupler to the hitch ball on the
towing vehicle securely and make sure the lock lever
is in the down position (locked).

Mixer Tow Bar Vehicle Connection (Pintle and Loop)

1. Make sure the bumper on the towing vehicle is
equipped to handle either a pentle or loop type tow bar
configuration.

2. After tow bar has been connected to mixer (see next
page), secure either type of tow bar to the towing vehicle,
following state and county towing regulations.

3. As a minimum, use a 1/2-inch bolt and nylock nut grade
5 when securing the tow bar to the towing vehicle and
to the unit being towed.

Replacing

Towing Components

PAGE 12 — STOW MS-93 MIXER — OPERATION MANUAL — REV. #5 (03/26/10)

STOW MS-93 PLASTER/MORTAR MIXER — SAFETY CHAIN CONNECTION

CAUTION

NEVER! tow the mixer with the safety chain removed. The

safety chain is intended to prevent complete separation
of the mixer from the towing vehicle in the event of a tow
bar failure.

Reference Figure 2 for the installation of the safety chain.

Tow Bar to Mixer Connection

1. Insert the tow bar through the round opening at the
bottom of the mixer stand.

Align the hole on the tow bar with the hole on the mixer

frame, and insert 1/2-inch bolt through tow bar and frame.
Secure tow bar to frame with 1/2-inch nylock nut. Tighten
to 40 ft.-lbs.

Always Tow with

a Safety Chain

2. Route the safety chain through the holes just above the
tow bar, located on each side of the mixer stand.

Loop the chain together and place under the tow bar.

Secure the loop with the connector link.

3. extend the safety chain along the length of the tow bar,
looping it through the tow bar's connector link. Remove
any excess chain slack.

4. Connect the free end of (clevis safety hook) the safety
chain to the towing vehicle. Remember it is critical that
the length of the chain be properly adjusted, to prevent
the draw bar and the front of the mixer stand from
dropping to the the ground (contact) in the event the
draw bar becomes disconnected from the towing vehicle.

CAUTION

DO NOT tow the mixer unless the mixing drum is com-

pletely empty. ALWAYS make sure the drum latch pin
is fully engaged to the right (Figure 3) of the drum stop
block. This will keep the drum from rotating.

Application

The STOW MS-93 series mixers (drum capacity of 9.0 cu.
ft./263 liters) are shipped completely assembled and have been
factory tested and are ready for use.

This mixer is only intended for the production of plaster and
mortar. The mixer must be used for its intended purpose
and is not suitable for the mixing of flammable or explosive
substances. The mixer must not be used in an explosive
atmosphere. This mixer has a batch capacity between 2-1/2
and 3-1/2 bags.

Power Plants

The STOW plaster and mortar mixer can be powered by
either a Honda GX240K1HA2 air-cooled, 4-stroke

engine

or a 2 HP electric motor. Refer to Table 2 for specific

gasoline

engine or electric motor data information.

Electrical

If mixer is equipped with an electric motor, make sure that
the power being supplied to the motor corresponds to the
voltage rating label on the motor. Supplying the wrong volt­age to the electric motor will cause severe electrical damage
to the motor.

Ensure that the extension cable is carefully laid out avoiding
wet areas, sharp edges and locations where vehicles might
run over it. Avoid allowing the extension cable to be trapped
underneath the mixer.

Unroll the extension cable fully or it will overheat and could
catch fire. Make sure that all extension cable connections are
dry and safe. Replace any defective or badly worn extension
cable immediately.

Hardware

Check all hardware on the mixer before starting. Periodically
inspect all hardware. Loose hardware can contribute to
early component failure and poor performance. Use Table
4 as general guideline when torqueing of mixer hardware
is required. Remember to keep all mixer hardware compo­nents tight.

Always make sure the OFF/ON switch on the electric motor
is in the OFF position before applying power.

It is strongly recommended when inserting the mixer's
power cord into a receptacle, that a G.F.C.I. (Ground Fault
Current Interrupter) receptacle be used (115 VAC applica­tions).

Extension Cables

The extension cable should be a 3-wire configuration that
includes a ground wire that conforms to UL code. The wire
cross section must be a minimum of 2.5 mm2. Choose an
extension cord of adequate current carrying capacity as
referenced in Table 6. Remember cable distance affects
the current-voltage capacity of the extension cable.

Engine Maintenance

For basic engine maintenance, refer to the engine mainte­nance section in this manual. For a more detailed engine

diameter of the outer races and also fill the hub grease
cap. Reassemble the hub and mount the wheel. Then
tighten the adjusting nut, at the same time turn the wheel
in both directions, until there is a slight bind to be sure all
the bearing surfaces are in contact.

Then back-off the adjusting nut 1/6 to 1/4 turn or to the

nearest locking hole or sufficiently to allow the wheel to
rotate freely within limits of .001" to .010" end play. Lock
the nut at this position. Install the cotter pin and dust cap,
and tighten all hardware.

MAIN GEAR AND DRIVE PINION ALIGNMENT

1. Disconnect the spark plug wire (gasoline engines). If
mixer is equipped with an electric motor remove power
cord from AC power receptacle. In addition make sure
the clutch engagement lever is dis-engaged to relieve
V-belt tension.

2. The countershaft and drive pinion are mounted on a
slotted base. To align drive pinion with main gear, loosen
the pillow block mounting bolts and move them until the
necessary alignment has been made. Remember gears
must be paralleled aligned not skewed.

3. Using your hand, slightly move (rock) the drive pulley
back and forth to determine the amount of backlash.
Insert feeler gauge between gears to determine backlash
distance. Backlash should range between 0.007- 0.012
inches (Figure 30).

INSPECT TOOTH CONTACT BETWEEN MAIN GEAR AND
DRIVE PINION

1. Coat 3 or 4 teeth at 3 different positions on the main gear
with yellow paint.

2. Rotate the drive pulley in both directions.

3. Inspect the tooth pattern.

4. If gear teeth are not contacting properly (Figure 31), adjust
pillow block to correct the problem.

Figure 31. Gear Teeth Alignment

Tires/Wheels/Lug Nuts

Tires Wear/Inflation

Tire inflation pressure is the most important factor in tire
life. Pressure should be checked cold before operation. DO
NOT bleed air from tires when they are hot. Check inflation
pressure weekly during use to insure maximum tire life and
tread wear.

WARNING

ALWAYS wear safety glasses when
removing or installing force fitted
parts. Failure to comply may result in
serious injury.

Table 9 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.

Eyesight Hazard

Tires and wheels are a very important and critical compo­nents of the trailer. When specifying or replacing the trailer
wheels it is important the wheels, tires, and axle are properly
matched.

WARNING

DO NOT attempt to repair or modify

a wheel. DO NOT install an inter-tube
to correct a leak through the rim. If
the rim is cracked, the air pressure in
the inter-tube may cause pieces of the rim to explode
(break-off) with great force and can cause serious eye
or bodily injury.

Lug Nut Torque Requirements

It is extremely important to apply and maintain proper
wheel mounting torque. Be sure to use only the fasteners
matched to the cone angle of the wheel. Proper procedure
for attachment of the wheels is as follows:

1. Start all wheel lug nuts by hand.

2. Torque all lug nuts in sequence. See Figure 34. DO NOT
torque the wheel lug nuts all the way down. Tighten each
lug nut in 3 separate passes as defined by Table 10.

3. After first road use, retorque all lug nuts in sequence.
Check all wheel lug nuts periodically.

NOTE

NEVER! use an pneumatic air gun to
tighten wheel lug nuts.

Suspension

The rigid type axle and associated hardware (Figure 35)
should be periodically inspected for signs of excessive
wear, elongation of bolt holes, and loosening of fasteners.
Replace all damaged parts immediately.

Figure 35. Axle Support Components

Mixer Cleaning

1. ALWAYS disconnect the spark plug wire (gasoline
engines) before cleaning the inside of the drum. If mixer
is equipped with an electric motor remove power cord
from AC power receptacle. In addition make sure the
clutch engagement lever is dis-engaged.

2. Make sure the rear section of the safety grate is connected
to the mixing drum.

WARNING

When rotating the mixing drum from the dump position to the
upright position, keep hands clear of safety grate. The pos-
sibility exists of hands or fingers being crushed (Figure 37).

Figure 37. Safety Grate (Crush Hazard)

7. When cleaning of the entire mixer is done, return mixing
drum to an upright position.

Clear of Drum!

Keep Hands

3. At the end of each day’s operation, place mixer drum in
an upright position and spray inside of tub immediately
with water to prevent lumps of dried mortar or plaster
from forming and contamination of future batches, DO
NOT allow a buildup of materials to form on the blades
or anywhere inside the drum.

4. Rotate mixer to dump position and remove debris.

5. Thoroughly clean the entire mixer, wheels, cabinet and
frame.

6. NEVER! pour or spray water over the engine or electric
motor (Figure 36).

Figure 36. No Spraying of Water

Mixer Storage

For storage of the mixer for over 30 days, the following is
recommended:

 Drain the fuel tank completely, or add STA-BIL to the

fuel.

 Run the engine until the fuel is completely consumed.

 Completely drain used oil from the engine crankcase

and fill with fresh clean oil, then follow the procedures
described in the engine manual for engine storage.

 Clean the entire mixer and engine compartment.

 Place the mixing drum in the down position (mouth facing

downward).

 Cover the mixer and place it a clean dry area, that is

protected from harsh elements.
