First inspection after delivery
It is mandatory that all delivery technicians check the machine settings at the end of the first running
operation. Factory settings can change during the initial phase of operation. If necessary, resetting should
take place right after initial run, without which faults are likely to set in.
After handing over the machine and approx. two hours into the initial operation, delivery technicians must
inspect the following items and settings:
1. Water safety switch
2. Solenoid valve
3. Pressure reducing valve
4. Motor safety switch^

Motor safety switch
10 – 16A for mixer and vibrator
Setting Up the Machine
Assemble the machine as follows:
- Set up the HM 6 straight
- Insert the mixing - dosing shaft
- Mount mixing tube and secure it on the hopper with snaps
Power Supply
- As per VDE regulations, connect the machine only to one electrical panel with
FI safety switch
- -Use a power cable 5 x 2,5 mm2with CEE plug 400 V, 5 x 16 A, 6h
(Item no. 20 42 33 50 )
Connect power cable
Connect vibrator (1)
Connect mixer (2)
The PFT HM 6 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.
If the direction of rotation is wrong, follow these instructions:
You can lock the main reversing switch by pushing the direction plate either to the
right or to the left. With that you have chosen the direction of rotation. If the switch is
turned to the left , it can be turned back to O, but not to the right side. The figure
printed on the plate shows you in what position the switch is locked

Water Supply
- Connect a 3/4“ hose to water mains. Open water discharge valve slightly. Let wa-
ter run through the hose to dearest and clean it. Wait till water comes out of the
hose
- Shut off water discharge valve
- Connect water hose to water inlet on the machine (dirt filter)

How can you avoid or rectify problems with the PFT HM 6?
Fault Cause Solution
Machine does not start!! Power
- Power connection in order? Check faults and rectify
- Proper connection to electrical
panel?
- FI safety switch activated?
- Main switch on?
Machine does not start! Material
Too much thick material in the hop-
per or mixing area?
Rectify faults. If needed, empty
hopper by half and start mixing
process all over again
- Material too dry in mixing tube? No water supply
Machine does not start! Water
- Solenoid valve (membrane opening)
clogged?
Check and rectify faults
- Solenoid coil faulty?
- Pressure reducing valve shut off?
- Water inlet at mixing tube clogged?
- Needle valve shut off?
- Cable to solenoid valve faulty?
Mixer motor does not start! - Mixer motor faulty? Check and rectify faults
- Connecting cable faulty?
- Plug or mounted socket faulty?
- Motor safety switch faulty or acti-
vated?
Water flow cannot be in-
creased!
- Dirt filter clogged? Clean or replace filters
- Filter on pressure reducer clogged?
- Hose or water connection too small? Increase size of water connection
Attach water booster pump
- Suction connection at water tank too
weak or too long?
Mortar stops flowing! - Poor mortar mix in mixing tube? Add water
- Dosing tube is damp, material is
congealing and blocking the dosing
area?
If this does not help, clean dosing
shaft; dry inlet at mixing tube and
start process all over again
Fluctuation in mortar consis-
tency-"thick/thin"?
- Too little water? Regulate water supply
- Pressure reducing valve adjusted
wrongly or faulty?
Replace faulty parts
- Dosing and/or mixing shafts worn
out?
- Power supply cable too long or too
weak?
- Too little material in hopper?

WARNING!
Assembly and maintenance tasks should only take place when the machine has been
switched off completely. Disconnect the machine from the electrical mains.
On a regular working day, clean the HM 6 only once at the end of operation.
Cleaning should take place in the following 3 steps:
1. When you finish work close the butterfly valve.
2. Let the system run till clean water is coming out (approx. 2 min)
3. Clean the hopper on the outside with a brush or dry mop. Use water to clean the
hopper only when it is empty.
4. Clean the hopper on the outside with a brush or dry mop. Use water to clean the
hopper only when it is empty.
WARNING!
No water should enter the bearings or electrical parts ( plug, main switch, motor con-
nections box).
While assembling cleaned parts, make sure they are really dry and clean. Connect
mixing shaft to dosing shaft.
WARNING!
Keep all snap locks and seals clean. Grease bearing tang and connectors regularily.
At subzero temperatures release all water!

Measures for Power Failure
The PFT HM 6 equipped with a restart lock. After a power failure switch on the ma-
chine at the main switch for operation.
Measures for Water Supply Failure
In case of a water supply failure, the PFT HM 6 will keep on running without mixing
the material. As soon as the fault is rectified, the HM 6 will mix material quite normally
again.
Measures for Subzero Temperatures
Empty the water manifold of the PFT HM 6 completely at subzero temperatures
- Depressure water connection and decouple it
- Open taps on manifold
Transport
- Disconnect power cable
- Depressure water connection and decouple it
- Dismantle machine components and transport them individually
Maintenance
WARNING!
Disconnect all power cables to carry out maintenance or assembly work.
After every operation, check the following parts for defects: bearings, hauling bracket,
all connectors, hose connections and power cable connections.
Remove and clean the dirt filter in the water inlet and in the pressure reducer at least
once every two weeks. Replace them, if necessary.
