EM-120PM — GENERAL INFORMATION

GENERAL

The Essick EM-120PM Series plaster and mortar mixers are
shipped completely assembled and have been factory tested.

The drum batch capacity of these mixers is between 3.5 and

4.0 bags. With proper care, they will give continuous service
year-after-year.

These mixers can be powered by either gasoline or electric
motors. The power from the engine is transmitted via the clutch/
reduction assembly directly to the paddle shaft. Therefore
providing high mixer torque and eliminating V-belts .

BEFORE STARTING

Before starting the engine, read the engine owners manual
and thoroughly understand the safety information.

Check the items listed below:

OIL LEVELS

Be sure to check the oil levels in the engine and engine reduction
unit before starting the unit.

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 the torque chart
below as a general guideline and keep all hardware tight:

GASOLINE ENGINE CARE

For care and operation of the gasoline engine, refer to the
engine manufacturer’s operating instructions furnished with the
engine. We recommend draining and refilling the engine
crankcase at least every thirty hours of operation. Check the
engine oil level daily.

GASOLINE MIXER OFF/ON SWITCH

This feature is on gasoline engine mixers only. Located on the
side of the engine cover. The purpose of this switch is to start
and stop the mixer in normal operation.

ELECTRIC MOTOR MIXER OFF/ON SWITCH

This feature is on electric motor mixers only. This switch is located
on top of the motor. Lift the engine cover to gain access to this
switch. The purpose of this switch is to start and stop the mixer
in normal operation. Never use the electric motor in an explosive
environment.

ENGINE THROTTLE AND CHOKE CONTROLS

Please refer to the engine owners manual for specific
instructions.

EM-120PM — CONTROLS

Figure 1. Mixer

Safety Grill — Provided for operator safety. This safety grill is

designed to keep hands and solid objects out of the mixing drum
when in use. This grill should be closed at all times when mixer
is in use. DO NOT remove the grill or grill opening bar. Keep the
grill clean by washing it down daily.

Bag Cutter— This feature allows compound mixing bags to be
opened easily, therefore allowing the contents of the bag to fall
directly into the mixing drum.

Mixing Paddles — Used in the mixing of material. This unit
uses four different types of paddles to provide a fast uniform mix.

Dump Handle — Pull this handle downward to dump the contents
of the drum. Push the handle upward to return the drum to its
vertical position.

Zerk Fitting — There is, on each end of the mixing drum a zerk
grease fitting. These fittings lubricate the dumping mechanism.
Lubricate both fittings at least twice a week.

Mixing Drum — Made of either
materials such as concrete, mortar, plaster are to be placed into
this drum for mixing. Always clean the drum after each use.

Tow Bar — When towing is required, connect tow bar to a
vehicle Reference page 14.

Engine Cover — Lift this cover to gain access to the engine
compartment.

ON/OFF Switch (gasoline) — This switch is provided on

with gasoline

engine cover. When activated it will shut down the engine.
ON/OFF Switch (electric) — This switch is provided on mixers

with electric motors. To gain access to this switch, lift the engine
cover. When activated it will shut down the electric motor.

Clutch Lever — Push the clutch lever forward, toward the tow
tongue end of the mixer to engage clutch. Once clutch is
engaged paddle shaft will rotate. To disengage clutch pull the
clutch backwards towards the engine.

The electric motor for this mixer is available in either a 5 HP
single-phase or 5 HP 3-phase configuration. The input voltage
requirement for these motors is either 230 VAC or 440 VAC only.

ELECTRIC MOTOR CONNECTION

A 12 inch electrical cable (Figure 2) with a pigtail at one end is
provided with the electrical motor for hookup to a power source.
Table 1. shows the required NEMA connector for the desired
motor horsepower rating. In addition, Table 2 also shows the
matching NEMA approved connector for the required extension
cord.

EM-120PM — TOWING

NOTE

Before towing, check with local and state laws for proper
compliance.

The tow bar and chain must be properly attached to the mixer
and towing vehicle prior to towing. Refer to the following
installation instruction:

Step 1.

Insert the Draw Bar into the main frame. Secure, utilizing the 3/4"
bolt (grade 5) and nylock nut. Tighten to 100 foot pounds.

REMOVE EXCESS
CHAIN (SLACK)

It is critical that the length of the chain be properly
adjusted, to prevent the
stand from dropping to the ground (contact) in the event
the Draw Bar becomes disconnected from the towing
vehicle.

BALL HITCH COUPLER

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

2. Use only the 2" ball diameter as indicated on your 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. Be sure the coupler is secured to the hitch ball and the lock
lever is down tight and locked.

Recheck tightness again after towing about 50 miles.

4. Check that trailer safety chains are properly connected.

■

Check the following before towing:

Extend the chain along the length of the Draw Bar, remove excess
chain (slack) and secure to bottom connector link. Secure the
chain to the towing vehicle, using the connector link.

EM-120PM — PADDLE BLADE ADJUSTMENT

Paddle blade adjustment is dependent on drum type,
using a polyethylene drum. Figure 4 illustrates the paddle blade adjustment when using a steel drum. When using a polyethylene
drum the paddle blade should come as close as possible to the drum end and side walls without making contact. If material builds
up on the drum, use a rubber mallet to dislodge the material without adverse effect to the drum.

EM-120PM — INITIAL START-UP

This section is intended to assist the operator with the initial
start-up of the EM-120PM mixer. It is extremely important that this
section be read carefully before attempting to use the mixer in
the field.

DO NOT use your mixer until this section is thoroughly
understood.

STARTING THE ENGINE (gasoline only)

The following steps outline the procedure for starting the engine.
Depending on the type of engine employed in the mixer the
steps may vary slightly. If your mixer has an electric motor
disregard this section.

1. Move the fuel shut-off lever (Figure 4) to the ON position.

CAUTION:

Failure to understand the operation of the EM­120PM mixer could result in severe damage to
the mixer or personal injury.

See Figure 1 (Page 10) for the location of any control referenced
in this manual.

LUBRICANTS

ENGINE OIL

1. Remove the engine oil dipstick from its holder.

2. Determine if the engine oil is low, add correct amount of
engine oil to bring oil level to a normal safe level.

CLUTCH OIL

1. Check the oil level in the clutch compartment, fill with 30
SAE engine oil if needed.

2. To start a cold engine, move the choke lever (Figure 5) to
the CLOSED position.

Figure 4. Fuel Shut-OFF Lever

REDUCTION GEAR OIL

1. Check the oil level in the reduction gear compartment, fill
with 90 SAE transmission oil if needed.

ZERK GREASE FITTINGS

1. Check the zerk grease fittings at each end of the mixing
drum. These grease fittings lubricate the dumping
mechanism. If the dumping handle is stiff or hard to move
lubricate these fittings.

3. Move the throttle lever (Figure 6) away from the slow
