machinery. Wear a face or dust mask if the operation is dusty.
Always wear safety goggles and/or face shields. Everyday
eyeglasses have only impact resistant lenses. They are not
safety glasses.
DO NOT ABUSE CORD
Never carry mixer by cord or yank it to disconnect it from
socket.
Keep cord from heat, oil and sharp edges.
EXTENSION CORDS
Extension cords must be no longer than 50 meters in length.
The wire section must be 1.5mm2 on 230V to allow sufficient
current flow to the motor. Improper use of extension cords
may cause inefficient operation of the mixer which can result
in overheating and motor damage.
Only extension cords to H07RN-F specification intended for
outdoor purpose may be used. Avoid use of free and
inadequately insulated connections. Connections must be
made with protected material suitable for outdoor use. Make
sure that any extension cord connections are dry and safe.
Ensure that the extension cord is carefully laid out avoiding
liquids, sharp edges and placeswhere vehicles might run over
it.Avoidallowingtheextensioncordtobetrappedunderneath

ELECTRICAL CONNECTION SPECIFICATIONS
This mixer is double insulated to Class II
protection andIP44Drated. Theinsulation
will only remain effective if the original
insulating parts are used for repairs and
the spaces between the original insulation
are maintained.
Double insulation eliminates the need
for the three-wire grounded power cord
andgrounded power supply system. Double
insulated tools can use either a two or three
wire extension cord.
Do not connect either core to
the earth pin.
The use of an Residual Current Device
(“RCD”), (earth leakage trip), on 230V
electrics is recommended. If using an
extension cable, plug it directly into the
RCD.
When operating in Switzerland, plug the
mixer only in sockets protected by fault
current breaker.

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. Also screw a M8X55 hex bolt with
lock and flat washers to the nut on the frame.
Tighten down.
1. Slide the bearing block on the shaft. Hold it
in place with 42 spiral ring.
2. Carefully,and withtwopeople, 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 fromthe
other side. Tighten with a wrench.
3. Turn the frame over and attach the axle
bracket with wheels in the same manner.
4. Make sure all bolts and nuts are tightened.

Mount the mixing blades inside the bottom drum
loosely as shown - Two holes are provided at
the base of the drum into which a M8X16 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 shouldbe placed under the
blade down against the drum.
2. Screw a M8X16 hex bolt with lock and flat
washers into each threaded hole in the
rim/ring gear. Make sure the tightening
process is carried out progressively.
3. Secure the mixing blades to the upper drum
by inserting two M8X16 cross headed screws,
from the outside through the holes in the
drum.
NOTE: Two arrows are labeled on upper
drum and bottom drum to make
their position relation. If you have
any difficulty 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.
4. A leather washer should be positioned inside
between the drum and blade. Secure the
mixingbladeon theinside usinga flat washer,
spring washer and nut.
5. Finally, ensure top and bottom mixing blade
mountings are tight.
THE TIPPING WHEEL
THE UPPER DRUM
1. Position the upper drum on bottom drum
over the rim, making sure the mounting holes
align in both as well as the labeled arrows.
1. Slide the locking plate over the large diameter
shaft at the leg end of the frame with the rim
facing inwards as shown. Secure with two
M8X25 bolts, each with a nut, lock and flat
washers.

NOTE: The wheel must be allowed to pivot
about the bolt so that the lugs on
the bracket can be engaged or
disengaged from the slots in the
locking plate.
THE TRANSMISSION CASE
Lining up the keyways, slide the transmission
case over the pinion shaft. Secure the case to
the frame with four M8 nuts.
2. The spring is clamped in its holder by a U
shaped plate for easier assembly. Slide the
wheel over the larger diameter shaft until the
holes in the bracket line up with the hole
drilled. Insert a M10X60 hex bolt and screw
on a nut with flat and lock washers from the
other side. Screw the nut up against the
bracket firmly, but not so tightly so as to
prevent the wheel from pivoting about the
bolt. Free the spring by removing the U
shaped plate.
OPERATION INSTRUCTIONS
DRUM TILTING

The drum is locked in position by lugs on the
self-locating tipping wheel which engage into
the locking plate on the mixer frame. To tilt the
drum, withdrawn the tipping wheel to dis-engage
the locking lugs. This then allows the tipping
wheel and drum to be turned in the same
direction.
To retain the drum in position, aligning the lugs
with the slots, release the tipping wheel a little
NOTE:
Do not throw material into the
mixer to avoid sticking firmly to
the back of the drum. Trickle it
steadily over the ram.
A built-in thermal protecter is
arranged in the motor to prevent it
from overheating. The thermal
protecter restores automatically
when the motor cools down.
while retaining the drum. Rotate the tipping
wheel until the locking lugs engage into the
locking plate on the mixer frame.
Loading/Mixing Position
For Mortar For Concrete
Emptying Position Storage Position
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.
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 off 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.
