4.2 HOW THE MACHINE WORKS
Discount-Equipment.com
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 mixing 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 mixing elements. An extendable hitch allows the hitch to
extend for towing and retracts during operation.

ability is obtained.
21
External Emergency Stop Switch (Typical)
Fig. 9 STOPPING
WARNING
Machine is shown with engine
hood open for illustrative purposes
only. Never operate with hood
open.
NOTE
Add sand a little at a time until
the desired consistency is
obtained.
j. Mix until there is an even consistency
throughout the mixture. Look into the drum
and watch until the mixture is the same
color throughout. This means the mortar
mix is evenly distributed throughout the
mixture.
k. Disengage the mixing clutch.
l. Release the drum lock and slowly tilt the
drum down to discharge the mixture.
m. Raise the hinged grill out of the way when
discharging the mixture.
n. Move the drum back into its mixing position
and lock. Immediately engage the mixing
clutch and add half the water for the next
batch. This will help to keep the drum and
mixing elements clean and prevent lumps
from forming in the mortar.
10. Mixing time:
Discount-Equipment.com
After all the ingredients have been added to the
drum, allow time for the material to reach a uniform
color and consistency. Watch the color and consistency of the mixture as the drum is turning. When
the entire mixture becomes a pale green color,
it means the mortar mix is uniformly distributed
throughout the mixture and can be discharged. If
the mixture is not uniform, the mortar will have
weak spots.
11. Emptying drum:
All Mixers are equipped with a lock for anchoring
the drum at the mixing angle. Move the wheelbarrow or other mortar receiver up to the side of the
Mixer. To empty the drum:
a. Disengage mixing clutch.
b. Release drum lock.
c. Move the wheelbarrow into position.
d. Slowly tilt the drum down.
e. Lift the hinged grill out of the way.
f. Fill the wheelbarrow.
g. Raise the drum back into its mixing position
and lock.
h. Engage mixing clutch.
i. Add half the water and sand for the next
batch. This will help to clean the mixing ele-
ments and inside of the drum.
NOTE
The Mixer is equipped with a solid grill
and bag splitter over the drum opening.
Place the bag of material on the grill/splitter and let the material fall into the drum.
Repeat with the next bag until the required
amount is added.
12. Mixing Elements:
A Mixer can be equipped with paddles or a spiral for
mixing the materials into a uniform mixture. Each
system has adjustable wipers to clean the sides and
ends of the drum. Maintain the wipers at 1/16 to
1/8 inch (1.5 to 3.0 mm) from the drum surface. A
large gap can result in a build-up on the surface.
This build-up will break loose and produce lumps or
chips in the mixture.
13. Preventing Build-up:
To maintain high quality mixing, consistent per-
formance and machine life, thoroughly clean the
mixer inside and out at the end of each day.
Under normal operating conditions, adding water
and sand and some aggregate to the drum immediately after emptying will wash and clean the mixing
elements and the inside of the drum and keep them
clean providing the wipers are set at 1/16 to 1/8
inch (1.5 to 3 mm) from the drum surface. If a slow
build-up is occurring, add water and coarse sand to
the drum at the end of the working day and let it
run for 15 minutes.
Fig. 10 FILLING
14. Removing Build-up:
Always disable the machine by unplugging the
power cord or disconnecting the spark plug wire.
Dried mix should be scraped out as necessary. DO
NOT strike the outside of the drum with a shovel,
hammer or other device to break up and loosen any
build-up, as this will dent and damage the drum.
At the end of the working day, thoroughly wash the
inside of the drum and the outside of the machine to
remove any residue build-up or clumps. Do not get
water on the electric motor or gas engine.
15. Drum speed:
The best mixing action occurs when the mixing ele-
ments are turning 30 to 35 RPM for the paddles and
40 to 45 for the spiral. Do not operate outside of this
speed range. Increasing the mixing element speed
does not signicantly change mixing characteristics.
Mixing time is much more important and the mixture must be thoroughly blended to obtain uniform
and consistent mortar.
22
16. Capacities:
Discount-Equipment.com
Each model has its own specied capacity.
When that capacity is exceeded, the excess spills out
of the drum making a mess of the working area and
increases the required time for mixing. It is recommended to use an additional mixer if more mixing
capacity is required.
NOTE
On the larger models, a full drum
can ll more than one wheelbarrow. Change wheelbarrows until
the drum is empty.

18. Selection of Mortar type:
The performance of masonry is inuenced
by various mortar properties such as workability, bond strength, durability, extensibility and compression strength. Since
these properties vary with mortar type, it
is highly important that the mortar type
selected for a particular application is the
one that best meets the end-user requirements. Table 1 is a general guide for the
selection of for various masonry wall construction. Selection of mortar type should
also be based on the type of masonry units
to be used as well as the applicable building code and engineering practice standard requirements such as allowable design
stresses and lateral support.

for illustrative purposes only. Never operate with hood open.
Fig. 30 ENGINE OIL CHANGING (DRAIN PLUG)
5.2.2 ENGINE SPEED SETTING
Every engine is shipped from the engine factory without gas or oil because of re hazards
during shipping. They are all set with a high
idle of 3500 RPM. Since no uids are added at
the Mixer factory, the RPM is not reset. When
the Mixer is delivered, the uids must be
added and the RPM reset. To reset the RPM,
follow this procedure:
9. Run the engine for 1 minute and check for
leaks.
10. If leaks are found around the drain plug,
tighten slightly and repeat Step 12.
11. Check engine oil level. Top up as required.
Fig. 31 ENGINE SPEED SETTING
1. Read the engine manual supplied with
the machine.
2. Add fuel and the specied motor oil to
the crankcase and oil to the gearbox.
3. Start the engine and run at wide open
throttle.
4. Use a screwdriver to reset the high idle
stop screw.
5. Count the mixing element revolutions to
determine engine RPM. Set the engine
speed to give 30-35 RPM for the paddles
and 40-45 RPM for the spiral when mixing.
6. Load the drum and count the mixing element rotational speed again.
7. Reset if the speed changes as required.
39
5.2.3 AIR CLEANER MAINTENANCE
Discount-Equipment.com
Each engine is equipped with lter to remove dust
and dirt from entering the air intake. To clean
the lter, follow this procedure:
1. Read the engine manual supplied with the
machine.
2. Unlatch and open the hood.
3. Remove the lter cover.

WARNING
Fig. 32 AIR CLEANER
5.2.4 BELT TENSION AND ALIGNMENT
A drive belt and pulley system transmits power from the
motor or engine to the gearbox for rotating the
mixing elements. A clutch lever through an over
center linkage swings the gearbox and pulley over
to tighten and engage the drive. The belt tension
must be properly set when the clutch is engaged
to prevent slipping and the pulleys aligned to prevent belt wear. To set the tension and alignment,
follow this procedure:
Machine is shown with engine hood open
for illustrative purposes only. Never operate with hood open.
Clutch Engaged
1. Unlatch and open hood.
2. Disable power source by unplugging power
cord or disconnecting spark plug wire.
3. Remove the pins on each end of the linkage
arm.
4. Lengthen or shorten linkage arm length by
turning yokes on the threaded rod.
5. Repin linkage arm.
6. Engage clutch. There should be a denite
feeling when the clutch linkage goes over
center. If not readjust linkage.
7. The belt is properly tensioned when the midspan deects 1/4 inch (6 mm) when pushed
on with a 10 lb force.
8. Align the pulleys by loosening the motor or
engine mounting bolts.
9. Slide or tap the power unit into position to
align the pulleys.
10. Tighten power unit mounting bolts to their
specied torque.

5.2.6 GEARBOX OIL CHANGING
Each machine is equipped with wipers on the mixing
elements to scrape the build-up from the inside of the
drum. After extended use, they will wear. They need to be
adjusted so they clean the sides of the drum. To adjust or
repair, follow this procedure:
1. Thoroughly clean the inside of the drum to remove all
the build-up.
2. Open hood and disable power source by unplugging
power cord or removing spark plug wire.
3. To adjust wipers, loosen mounting bolts.
4. Tap or slide wipers to 1/16 inch (1.5 mm) from the
drum.
5. Tighten mounting bolts to their specied torque.
6. If there is no more adjustment available, remove old
wipers.
7. Replace wipers.
8. Set at 1/16 inch (1.5 mm) from the drum.
9. Tighten mounting bolts to their specied torque.
The gearbox transmits power from the belt/pulley drive to the
mixing elements in the drum. As the gearbox breathes during its warming and cooling cycle, contaminants can enter
through the breather. Change the oil annually to remove
these contaminants
To change the oil, follow this procedure:
1. Open the hood.
2. Disable the power source by unplugging the power cord
or removing the spark plug wire.
3. Place a pan under the drain plug.
4. Remove the drain, level and ll plugs and allow the oil to
drain for 10 minutes.
IMPORTANT
Allow the gearbox to cool before
changing oil. Hot oil can cause
burns if it contacts exposed skin.
Draining works best if the oil is
warm.
5. Clean the drain plug.
6. Install the drain plug and tighten.
Paddles
7. Add 1 quart of SAE 80W90 gear oil through the ll plug.
8. When the oil in the gearbox just lls the threads of the
level plug, the gearbox is at the proper level.
9. Install the level and ll plugs and tighten.
IMPORTANT
If the air passage
through the breather
is plugged, soak the
breather in solvent for
an hour and blow out
with an air hose.
NOTE
There is a hole in the top of the
shroud (with a rubber plug) for
lling the gearbox.
