POWER CORD.
OPERATION
Start the engine / motor as instructed above and
allow gasoline engines to reach operating
temperatures. Close the engine cowl. NEVER
operate the mixer with cowl open. NEVER operate
the mixer with the drum guard open or removed.
Move the clutch lever clockwise to the DOWN
position to engage the drive train and set mixer
paddles in motion.
The mixer is now ready for the addition of the
mortar mix. For best results proceed as follows:
. Pour half the required amount of water
into drum.
2. Add half the required amount of sand.
3. Add the total required amount of mortar
mix (cement, lime, etc.).
4. Add the balance of sand and water.
After mixing for the proper length of time
(homogeneous mix obtained), discharge the mix
from the drum by using the dump handle to dump
the drum and control the discharge.
After discharge, if another batch of mortar is to be
mixed, return the drum to the mixing position and
make sure the drum latch is engaged. Immediately
pour in half of the required water for the next batch
with paddles turning. This will clean the paddles
and drum between batches and help prevent lumps
of dried mortar from forming and contaminating the
next batch.
If no more mortar is to be mixed in the next hour or
so, the mixer drum and paddle should be thoroughly
cleaned. If no more mortar is to be mixed that day,
the entire mixer should be thoroughly cleaned inside
and outside to insure maximum life and
performance.
CLEANING
For consistent performance, long life and continued
high quality mixing of plaster or mortar, thoroughly
clean the mixer inside and out at the end of each
day's operation. To prevent lumps of dried plaster
from forming and contaminating future batches of
plaster or mortar, do not allow build up materials to
form on drum guards, around paddles or anywhere
inside the drum.
Before cleaning, shut the engine or motor and
disconnect the spark plug wire or electric cord to
prevent accidental starting. Spray the mixer with
water before the mix dries to remove any
accumulations. Dried mix should be scraped out as
necessary. DO NOT beat on the drum with a
shovel, hammer or other device to break up
accumulations of dried mix, as this will dent and
damage the drum.

HARDWARE
Periodically inspect all hardware on the mixer and
engine / motor. Loose hardware can contribute to
early component failure and poor performance.
NOTE: Some hardware is used to retain parts that
have to move freely for correct operation of this
unit. These items include the guard lifter and drum
guard. The hardware for these items should be snug
enough to prevent excessive play, yet loose enough
to allow the parts to pivot freely.
