4 OPERATION
4.1 TO THE NEW OPERATOR
OWNER
The Crown Construction Equipment
Mortar Mixer is designed to efficiently
combine water, lime, aggregate and
cement into a mixture forforming mortar.
It is the responsibility of the operator to
be familiar with the machine before
starting.
It is the responsibility of the owner or
operator to read this manual before
starting. Follow all safety instructions
exactly. Safety is everyone's business.
By following recommended procedures,
a safe working environment is provided
for the operator, bystanders and the
environment.
Many features incorporated into this
machine are the result of suggestions
made by customers like you. Read this
manual carefully to learn how to operate
the machine safely and how to set it to
provide maximum mixing efficiency. By
following the operating instructions in
conjunction with a good maintenance
program, your Mixer will provide many
years of trouble-free service.
4.2 HOWTHEMACHINE
WORKS
The Mortar Mixer consists of a large tilting drum
with internalrotating 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 mixing elements. A
set of pulleys anddrive 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
mixing elements. An extendable hitch allows the
hitch to extend for towing and retracts during
operation.

4.5 CONTROLS
Before starting to work, all operators should familiarize 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 procedures 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 shutoff valves:
Each engine is equipped with a shut-off valve between the fuel tank and
the carburetor.

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 firmly and pull the
rope sharply to start the engine.
Close the choke if the engine is cold.
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.
2. Electric Motor (Typical):
a. Master ON/OFF:
This switch controls the power to the electric motor that turns the
mixing elements in the drum. Move the switch rearward to turn ON and
forward for OFF.
2. Drum Position:
This lever sets the position of the mixing drum. Move the lever down
to empty the drum and up to mix.
3. Drum Position Lock:
This lever locks the mixing drum in its mixing position. Pull up on lever
to release the lock. It will automatically engage when the drum is
moved into its mixing position
4. Drum Position Lock: This lever locks the mixing drum in its mixing
position. Pull up on lever to release the lock. It will automatically
engage when the drum is moved into its mixing position.
5. Drive Engagement Clutch: This lever engages and disengages the
mixing elements in the drum. Move to the left to disengage the drive and
ease to the right to engage. Always disengage before starting the engine
or motor.

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 aggregate 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.
5. Starting machine:
A. Electric motor-powered units:
a. Check that everyone is clear of the ma- chine.
b. Move power engagement clutch to the left to disengage the mixing elements.
c. Unlatch and open the hood.
d. Turn the power switch ON.
e. Close and latch the hood.

1. Read and understand the Operator’s Manual and all safety signs before operating, servicing, adjusting, or
cleaning the Mixer.
2. Do not allow riders on the machine during transport.
3. Install, close and secure all guards, shields and hoods before starting or operating.
4. Stop engine or motor, disconnect spark plug wire or unplug power cord, and wait for all moving parts to
stop before servicing, adjusting, repairing, or cleaning.
5. Clear the area of all bystanders before starting.
6. Keep hands, feet, hair and clothing away from moving parts.
7. Keep working area clean and dry to prevent slipping and tripping.
8. Do not run the mixer in an explosive atmosphere or in a poorly ventilated or enclosed area.
9. Wear appropriate hearing protection when operating for long periods of time.
10. Always attach safety chain when towing.
11. Do not exceed a safe travel speed when towing. Slow down for corners and when going over rough
terrain.
12. Review safety instructions with all operators annually.
Gas engine powered units:
• Do not place hands in the drum unless the engine is OFF and the spark plug wire is disconnected.
• Stay away from hot engine components during operation.
• Do not smoke when refueling gas engine.
Electric motor-powered units:
• Do not place hands in the drum unless the motor is OFF and the power cord unplugged.
• Have a licensed electrician wire up and provide power to the motor. • Only use a power cord that is
grounded. • Always use an electrical cord with the required power carrying capacity.
