Emptying must be carried out with the mixing drum working, moving
the drum mouth downwards by turning the hand-wheel provided (ref.11,
If part of the batch is left in the drum for later use, it is necessary to leave
the drum turning. In any case, minimise the time the batch stays in the
drum after the required consistency has been reached.
Every two working months, check the following:
dirt and rubbish.
Check on a weekly basis that the contacts of the plug and socket con-
nector on the electrical panel are clean, dry and free of rust.
If the cement mixer is to be used after standing for a long time outside,
check that the tipping reduction gear is properly lubricated.
After each daily work session or before long periods of inactivity, the
mixing drum must be cleaned thoroughly both inside and outside.
When using a hose for cleaning, do not direct the spray into the plug-
switch unit.
Clean the outside of the mixer with a brush and water. Scrape off any
cement or concrete deposits.
There should not be any deposits of cement or concrete inside the drum.
The inside of the drum can be cleaned better if, at the end of the work
session or before a prolonged period of inactivity, the drum is rotated
with a few shovel-fulls of gravel and water. This will prevent any residue
of cement or concrete from hardening.
The mixing drum must not be struck with hard objects such as hammers
or shovels, etc. A dented drum will reduce the mixing effects and make

Having to replace one or both wheels, it is recommended to use a fork-
lift truck:
1. Raise the machine by a few centimetres, engaging the forks in the
special seats (ref.B; Fig.3).
2. Pull out the split pin (pos.28, pag.24) and remove the wheel (ref.29,
pag.24).
4. Lower the machine to the ground.
If you do not have a fork-lift truck, proceed as follows:
1. Raise the machine a few centimetres from the ground, resting the
wheel axle on a sturdy and stable support (e.g. piece of wood or other
homogeneous material). The height of this piece should be slightly hi-
gher than the wheel radius.
2. Pull out the split pin (pos.28, pag.24) and remove the wheel (ref.29,
pag.24).
4. Lower the machine to the ground.
1. carefully clean the cone of the shaft of the reduction unit and the cone
