WARNING
CALIFORNIA - Proposition 65 Warning
Engine exhaust and some of its constituents and some dust created by power sanding, sawing,
grinding, drilling and other construction activities contains chemicals known to the State of California
to cause cancer, birth defects and other reproductive harm.
Some examples of these chemicals are:-
Lead from lead-based paints
Crystalline silica from bricks
Cement and other masonry products
Arsenic and chromium from chemically
treated lumber
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals:
ALWAYS work in a well ventilated area, and work with approved safety equipment, such as dust
masks that are specially designed to lter out microscopic particles.

The Mortar Mixer consists of a large tilting drum with
internal rotating paddles or spiral blades for combining
cement, lime, aggregate and water into a mixture for
forming mortar. The enclosure on the back end houses
the electric motor or gas engine for turning the mix-
ing elements. A set of pulleys and drive belt within the
enclosure transmits rotational power to a gearbox that
powers the mixing elements.
A lever on the front end of the drum assembly allows
the operator to tilt the drum to the required position
for mixing and emptying. A lever on the bottom of the
frame extends to the power compartment and moves
the gearbox to engage the drive belt for turning the mix-
ing elements. An extendable hitch allows the hitch to
extend for towing and retracts during operation.

Ecient and safe operation of the Mixer requires that
each operator reads and understands the operating
procedures and all related safety precautions outlined
in this section. A pre-operation checklist is provided
for the operator. It is important for both personal
safety and maintaining the good mechanical condi-
tion of the machine that this checklist is followed.
Before operating the Mixer and each time there-after,
the following areas should be checked o:
1. Gas Engine Units:
a. Check all uid levels: fuel, engine oil and
gearbox oil. Refuel or top up oil as required.
b. Check the tires and be sure that they are
inated to the specied pressure.
c. Check the tension and alignment of drive belt
when engaged. Tension or align as required.
d. Check the engine speed at maximum. Be sure
it is set to give a paddle rotation speed of 30-
35 RPM and a spiral rotation of 40-45 RPM.
e. Use the emergency stop switch to stop the
engine to be sure that it works. Repair or
replace if it is not functioning.
f. Lubricate machine per Maintenance Section.
g. Close and secure all guards, shields and
hoods.
2. Electric motor units:
a. Check the tension and alignment of drive
belt when engaged. Tension and align as
required.
b. Check gearbox oil level. Top up as required.
c. Check the tires and be sure that they are
inated to the specied pressure.
4.3 PRE-OPERATION CHECKLIST

4.4 PRE-START PROCEDURES
All machines are sent from the factory in a special ship-
ping conguration to prevent spilling oil or gas. As a
result, the following items must be done prior to start-
ing the machine:
1. Gas engine powered units:
a. Fill the engine crankcase with its specied oil
(SAE 30W or 10W30 oil).
Refer to engine manual for oil specications if
operating in unusual temperature conditions.
b. Add SAE 80W90 oil to the gearbox.
c. Fill the fuel tank with regular unleaded gas. Do
not use an ethanol blend.
d. Start the engine and set the high idle speed
to give a mixing element rotation speed of 30
to 35 RPM for the paddles and 40 to 45 for the
spiral.
e. The machine is shipped with the drum tilt
lever pointing down or fastened to the safety
grill. Remove lever and turn it around so it is
pointing up. Tighten mounting bolts to their
specied torque.
f. Be sure the emergency stop switch is function-
ing properly.
IMPORTANT
The engine is supplied from the engine
manufacturer with the high idle speed set at
approximately 3500 RPM and no gas or oil.
As a result, the engine is not run when it is
mounted to the Mixer. It is the responsibility
of the customer to add oil and gas, start the
engine and reset the high idle RPM to the op-
erating range (Refer the Maintenance Section
for procedure).
IMPORTANT
Engine warranty is void if the
engine is run without oil.
d. Lubricate machine per Maintenance Section.
e. Close and secure all guards, shields and hoods.

4.5 MACHINE BREAK-IN
A special break-in procedure has been developed to insure the
integrity of the machine when rst starting. When using the
machine for the rst time, follow this procedure.
A. Before Starting:
1. Read the engine and Mixer Operator's Manuals.
2. Review and follow pre-start procedures before start-
ing machine (Section 4.4).
B. At 1/2, 2, 5 and 10 hours:
1. Check all machine uid levels: Fuel, engine oil and
gearbox oil. Refuel or top up as required.
2. Retorque wheel bolts.
3. Check for loose hardware. Tighten to specied torque.
4. Check drive belt tension and alignment when en-
gaged. Tension and align as required.
5. Lubricate the points dened in the Maintenance sec-
tion.
6. Then go to the service schedule as dened in the
Maintenance section.
C. At 10 hours:
1. Change the engine oil.
2. Change the gearbox oil.
3. Replace with their specied oil.
4. Then go to the oil replacement schedule as dened in
the Maintenance section and engine manual.

2. Electric motor powered units:
a. Have a licensed electrician provide power to the
motor. Use only a grounded cord with sucient
capacity to carry the required load.
b. Have a licensed electrician wire up the motor if it is
not a 110 volt unit.
c. The machine is shipped with the drum tilt lever
pointing down. Remove lever and turn it around
so it is pointing up. Tighten mounting bolts to their
specied torque.

f. External Emergency Stop Switch:
This push-pull switch shorts out the power to
the gas engine ignition system and is located
on the outside of the hood. Push the switch
in to stop the engine and pull out to allow it
to run.
4.6 CONTROLS
Before starting to work, all operators should familiar-
ize themselves with the location and function of the
controls.
1. Gas engine powered units:
Always read the engine Operator's Manual supplied
with the machine for the detailed operating proce-
dures for your engine.
a. Ignition switch:
This switch controls the electrical power to the
engine electrical system. Turn the switch clock-
wise to turn the electrical system ON and the
engine will run. Turn counterclockwise to stop
the engine.
b. Fuel shuto valves:
Each engine is equipped with a shut-o valve
between the fuel tank and the carburator. Slide
the fuel valve toward the block to turn ON and
away for OFF. Turn the fuel OFF when not in use
or before transporting.
c. Throttle:
This lever controls the engine RPM. Move the
lever laterally to increase or decrease the RPM.
Always run at maximum throttle operating.
d. Choke:
The choke controls the fuel/air mixture to the
engine. Close the choke when starting if the
engine is cold. Open the choke as the engine
warms. Always open the choke fully during
operation.
e. Starting rope:
This retracting rope and T bar is used to turn the
engine over for starting. Grasp the T bar rmly
and pull the rope sharply to start the engine.
Close the choke if the engine is cold.

familiar with the machine. When operating, follow this
procedure:
1. Review and follow the Pre-Start and Pre-Operation
checklists.
2. Review the location and function of all controls.
3. Determine ratio of the cement, lime, water and ag-
gregate required for your mixture. Always use the
same mixture ratio for each batch.
4. Be sure the mixing elements turn at 30 to 35 RPM
for the paddles and 40 to 45 RPM for the spiral to
insure proper mixing.
