 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.

Preparing the achine
18 2017-08-07
Basic infor ation
WARNING!
Danger of injury due to incorrect operation!
Improper operation may lead to serious damage to
persons or property.
Therefore:
Carry out all operating steps according to the
instructions in this user manual.
Prior to starting your work, ensure that all covers
and protection devices are installed and work as
intended.

operation.
Ensure order and cleanliness in the work area!
Loose components and tools on top of one
another or lying about pose potential accident
risks.
Increased noise level may cause permanent
hearing deficiencies. At close range of the
machine 78 dB(A) can be exceeded due to
operational conditions. Close range is a distance
of less than 5 metres to the machine.
15 Preparing the achine
Prior to operating the machine carry out the following steps for
preparing the machine:
Fig. 10: Grille cover
DANGER!
Rotating dosing shaft!
Risk of injury when reaching into the material
container.
– During machine preparation and operation, the
grille cover (1) must not be removed.
– Never reach into the running machine.
Fig. 11: Set-up
The operating elements have to be freely accessible.
Put up the machine on a stable, even surface and secure
against unwanted movements:

Fig. 12: Power supply 400 V
1. Connect machine (1) to three-phase network 00V.
DANGER!
Danger of death fro electric current!
The connection line has to be fused
properly:
Connect the machine only to a power source
with permissible RCCB (30 mA) RCD
(residual current operated device) type A.
16.2 Power connection with control cabinet
Fig. 13: Power supply 400 V
1. Connect machine (1) to three-phase network 00V.
DANGER!
Danger of death fro electric current!
The connection line has to be fused properly:
Connect the machine only to a power source
with permissible RCCB (30 mA) RCD
(residual current operated device) type A.
16.3 Check the individual connectors
Fig. 14: Power connections
 Connect water pump (1).
NO E!
he booster pump is necessary should the water
pressure be less than 2.5 bar when the machine is
running.
 Check connection of mixing motor (2).
 Check connection of Vibrator (3).
WARNING!
Danger to life fro rotating parts!

17 Check the direction of rotation
17.1 Main switch on the control cabinet
Fig. 15: M ain switch
Switch on the main selector switch (1).
HINWEIS!
Check the direction of rotation.
If the direction of rotation is incorrect, the yellow
direction indicator (2) lights up and the following
steps must be carried out:
he main selector switch (1) is locked in the neutral
position by sliding the selector plate to the left or
right in a preset position, thus selecting the direction
of rotation. If the switch is on the left, the switch can
be switched back to zero, but is disabled for the right
position.
17.2 On/Off switch with phase inverter
Fig. 16: On/Off switch with phase inverter
Rotating field control:
 All three phases are present and the rotating field is OK: LED
green lights up.
 One phase is missing: LED flashes red.
 L1 is missing: LED red flashes 1x (fast).
 L2 is missing: LED red flashes 2x (fast).
 L3 missing: LED red flashes 3x (fast).
 Wrong rotating field: LED red is always lit.
The PFT HM 2 is equipped with a phase display that will light up if
the direction of rotation is wrong. With the right phase order, the
mixing shaft should rotate clockwise.
The PFT HM 2 is equipped with a contact reversing switch that
enables the user to change the direction of rotation.
To do this, disconnect the power cable and alter the contacts with
a screw driver (1).
