THE STAND
1. With a split pin inserted into the
inner holes in each stub axle, place
a flat washer, then a wheel followed
by another flat washer. Insert another
split pin into the axle holes outside
each flat washer. Bend each side
of the pins outward so they do not
fall out.
2. With the frame lying on its side,
attach the support leg as shown.
Insert two M8X70 hex bolts through
the holes from one side, then flat
washers, lock washers and nuts
from the other side.

THE BOTTOM DRUM
1. Slide the bearing block on the shaft.
Hold it in place with Ø 42 spiral ring.
2. Carefully, and with two people, set the
bottom drum with support arm onto the
side supports of the stand as shown,
so that the bearing blocks slot into the
channels provided by the side supports.
The larger diameter shaft should be at
the leg end of the stand.
3. At each side, line up the holes in the
side support with those in the bearing
block and insert a M8X65 hex bolt from
one side, then a flat washer, lock washer
and nut from the other side. Tighten
with a wrench.
THE MIXING BLADES
Mount the mixing blades inside the bottom
drum loosely as shown - Two holes are
provided at the base of the drum into
which a M8X20 bolt may be inserted from
the outside. A leather washer, flat washer,
lock washer and a nut should be threaded
on loosely on the inside. The leather
washer should be placed under the blade
down against the drum.
NOTE: Two arrows are labeled on upper
drum and bottom drum to make their
position relative. If you have any diculty
in correctly positioning the mixing blades,
it is helpful if you temporarily mount the
upper drum on the top of the bottom drum,
rotating it so that the two arrows line up.

into each mounting hole in the rim.
Secure each bolt from below with a
flat washer, lock washer and nut. Make
sure the tightening process is carried
out progressively.
3. Secure the mixing blades to the upper
drum by inserting two M8X20 cross
headed screws, from the outside
through the holes in the drum.
4. A leather washer should be positioned
inside between the drum and blade.
Secure the mixing blade on the inside
using a flat washer, spring washer
and nut.
5. Finally, ensure top and bottom mixing
blade mountings are tight.
THE TIPPING BAR

OPERATING INSTRUCTIONS
DRUM TILTING
The spring-loaded tipping bar with locking lugs provides an easy positive control of
the drum which can be locked in the mix, discharge and stored position.
The drum is locked in position by lugs on the self-locating tipping bar/wheel which
engage into the locking plate on the mixer frame. To tilt the drum, withdrawn the
tipping bar to dis-engage the locking lugs. This then allows the tipping bar and drum
to be turned in the same direction.
To retain the drum in position, aligning the lugs with the slots, release the tipping bar
a little while retaining the drum. Rotate the tipping bar until the locking lugs engage
into the locking plate on the mixer frame.

LOADING
Completely unwind the extension cord. Connect it to the concrete mixer first
before plugging in power supply.
Always start the mixer before loading the drum. Loading the drum
with drum rotating.
Do not throw material into the mixer to avoid sticking firmly to the back of the
drum. Trickle it steadily over the ram.
NOTE: A built-in thermal protector is arranged in the motor to prevent it from
overheating. The thermal protector restores automatically when the motor
cools down.

For best results, proceed as follows:
1. Add the required amount of gravel into the drum.
2. Add the required amount of cement into the drum.
3. Add the required amount of sand into the drum.
4. Pour the required amount of water into the drum.
EMPTYING
Do not turn mixer o while full of load. Emptying the drum with drum rotating.
CLEANING
Never put hands inside the drum with drum rotating.
Thoroughly clean the mixer at the end of each day’s operation. Keep your mixer
clean. The slightest trace of material left in the drum will harden and attract more
each time you use it until the machine is useless. Dried cement should be scraped
out of the drum. Do not throw bricks into mixer drum to clean it out. Do not beat
on the drum with a shovel, a hammer or other tools to break up accumulations of
dried cement mix, as damage to the mixer may result. The drum may be scoured
for approximate 2 minutes, using 1” gravel and water mixture. Then discharge the
gravel/water mixture and hose down the drum assembly inside and out. The IP44D
protection class construction of the concrete mixer enables you to hose down the
drum assembly safely.
Do not pour or spray water directly over the motor cover, especially the
openings in it.
Wipe o any external material on the motor cover. Do not use petrol,
turpentine, lacquer or paint thinner, dry cleaning fluids or similar products.
The use of chemical products or solvents may aect the properties of the
cover which was made of high density polyethylene PET.
MAINTENANCE INSTRUCTIONS
Ensure the extension cord is always unplugged before the motor cover is
removed. The drive belt is under constant even tension by a spring loaded
jockey. No adjustment apart from a touch of grease on the spindle.
The bearings are sealed for life.
