2 Testing
2.1 Testing by machine operator
Before the start of each work shift, the machine operator must test
the effectiveness of the control and safety devices as well as check
the proper attachment of all protective devices.
During operation, construction machines must be tested by the machine
operator for their operational safety.
If defects are found in the safety devices or any other area that could
impair safe operation, the supervisor must be notified immediately.
For defects posing a hazard to persons, the operation of the construction
machine must be halted until the defect is eliminated.
2.2 Periodic inspection
Construction machines must be tested for safe operation by a specialist
as the usage conditions and operating circumstances require, but at least
once a year.
Pressure vessels must undergo the prescribed inspections by
authorised experts.
The inspection results are to be documented and must be stored at least
until the next inspection.

12 Function
12.1 Description
1 2 3
Fig. 5: Description
The PFT MULTIMIX is a powerful batch mixer that is
particularly suitable for special mixtures comprising
different components.
The mixed material can be added straight into
the hopper (2) and be prepared via the water inlet (3)
using the specified quantity of liquid.
Powerful mixing arms save time while producing
homogeneous mortar mixtures.
The mixed material is quickly and cleanly drained
using a flat slide valve (1) on the hopper base.
12.2 Areas of application
Fig. 6: Use
Areas of application:
Concrete refurbishment
PCC and SPCC mortars
Fine concrete
Screeds
Furnace construction
Flue construction
Powder adhesive
Mineral plasters
Acoustic plasters*
Synthetic resin plasters
Epoxy resins
Granulates
* The TURBO mixing unit might have to be screwed
on for sensitive mortars, e.g. acoustic plasters.
The corresponding guidelines of the mortar manufacturer
have ultimate priority.

20 Operation
20.1 Safety
Personal protective equipment All machine operators must wear the following protective equipment:
Protective work clothing
Safety goggles
Safety gloves
Safety shoes
Ear protection
NOTE!
The warning signs illustrated in this chapter relate to
additional protective equipment that must be worn
for particular working conditions.
Basic information
WARNING!
Danger of injury due to improper operation!
Improper operation can lead to serious injuries
or equipment damage.
Therefore:
Carry out all operating steps as described this
operating manual.
Before starting any work, ensure that all covers
and protective devices are installed and
functioning properly.
Never disable protective devices during operation.
Keep the operating area clean and tidy.
Components and tools that are stacked on one
another or left lying around can cause accidents.
An increased noise level can cause permanent
hearing loss. Operation can result in noise
that exceeds 78 dB (A) in close proximity to
the machine. Close proximity is defined as
the area within 5 metres of the machine.
