ELECTRICAL CONNECTIONS
Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply
through an approved 13 amp BS1363 plug, or a suitably fused isolator switch.
If the plug has to be changed because it is not suitable for your socket or
because of damage, it must be removed and a replacement fitted, following
the wiring instructions shown below. The old plug must be discarded safely as
insertion into a power socket could cause an electrical hazard.
The wires in the mains lead should be
wired up in accordance with the
following colour code:
• Connect the BROWN coloured
wire to the plug terminal
marked a letter “L”.
• Connect the BLUE coloured wire
to the plug terminal marked a
letter “N”.
We strongly recommend that this machine is connected to the mains supply
via a Residual Current Device (RCD). If you are not sure, consult a qualified
electrician.
DO NOT try to carry out any repairs yourself.
This symbol indicates that this is a Class II product and does not

OPERATION
1. Switch the mixer on by pressing
the green (I) switch on the motor.
Stop by pressing the red (O)
switch.
2. Introduce water first, to prevent
the mixer from clogging.
3. Add cement as required.
4. Add aggregate to suit.
• Do not load the drum when the
machine is switched off. Always set the machine running before
filling.
• Avoid stopping and starting the mixer while there is a heavy weight
of material inside the drum as the extra strain could be harmful to
the motor.
• Keep the drum rotating while emptying the mixture.
5. When emptying, grip the tilt wheel
firmly and turn the wheel to
disengage the locking lugs.
6. Use the wheel to tip the mixer
drum forward.
• Only discharge the mixer when
a suitable receptacle for the
cement mix is in position.
• Do not operate this machine
on a steep gradient. Always
stand the mixer on firm, level ground where it cannot tip over.
• Always keep water away from the motor and other electrical
components as far as possible.
It is essential that the mixer is kept clean. Dried cement inside the drum will be
very difficult to remove. For the mixer to perform at its best it must be
thoroughly cleaned after every use.
WARNING: REMEMBER THAT THE CENTRE OF GRAVITY OF THE LOADED
MIXER MAY PRESENT A HAZARD WHEN OPERATING ON UNEVEN GROUND.

CARE AND MAINTENANCE
BEFORE STARTING WORK
Inspect the power cable and ensure it is free from damage and is not in
danger of being damaged by vehicles, equipment or other operations taking
place on the work site.
AFTER USE
At the end of the working shift it is essential that the machine is hosed down
thoroughly with clean water, being sure to remove all traces of the cement
mix especially from around the mixing blades. The drum may be scoured for a
couple of minutes running using course gravel and water which is then
discharged and the drum finally hosed clean.
Never allow cement residue to harden inside the drum and thereafter be
tempted to beat on the drum with hand tools to dislodge such accumulations
of dried cement.
The machine is constructed to IP44D ingress protection which enables the
drum and any other areas to be hosed down safety.
STORAGE
The mixer can be better stored with
the axle frame and support stand
folded away.
Remove the top bolts only from the
axle frame and support stand and
lower the mixer to the floor with the
help of an assistant. Loosely re-fit the
bolts and nuts into their respective
holes for safe keeping.
Leave the mixer with the drum
inverted to exclude water or debris and always store the mixer in a dry place
out of reach of children.
PERIODICALLY
After extensive use, inspect the paintwork and remove any rust that may be
apparent before touching up where necessary with a rust resistant paint.
CAUTION: OWING TO THE WEIGHT AND BULK OF THE MIXER, TWO
PEOPLE WILL BE REQUIRED TO LOWER THE MIXER AND RE-FIT THE BOLTS.
