Installation and commissioning
18
8 Installation and commissioning
After the machine has been unpacked, check it for any damages caused during transportation. If there
is any damage, please notify the transport company and your local PFAFF agency.
The machine must only be installed and commissioned by qualified personnel. All
relevant safety regulations must be strictly adhered to!
8.01 Installation
A suitable connection for electricity must be available at the machine’s location, see Chapter 3
Specifications, p. 10. An even and firm foundation as well as sufficient lighting must also be available at
the machine’s location.
Slide the machine off the pallet.
If the foundation is not completely even
the machine must be stabilized using the
adjustable foot at the right back end of
the machine. Loosen the lock nut 2
with a
suitable wrench and turn the adjusting
screw 1with a suitable screwdriver to the
right or left until the machine stands
steady. Hold the adjusting screw 1with
the screwdriver
in position and tighten the
lock nut 2.
Connect the plugs from the pedal and from any existing knee switch to the control box.

Installation and
commissioning
19
8.02 Commissioning
Clean the machine thoroughly if necessary.
Check the machine, particularly its electrical wiring, for any damage.
Have a qualified person check whether the motor can be driven with the existing power voltage.
If there are any differences, the machine must definitely not be operated!
The machine must only be connected to a suitably grounded socket!
8.03 Switching the machine on/off
To switch on the machine, turn the
main switch (location of the switch see
section 7.01, p. 14) to position 1. After
approximately 30 seconds the control
panel will display the base menu last
called up, before the machine was
switched off, see Chapter 10 Sealing,
p. 23 ff.
To switch off the machine, turn the main switch to position 0.

Preparation
20
9 Preparation
All regulations and notes in this manual must be observed! Special attention must be
paid to the safety regulations!
All setting-up work must only be carried out by personnel with the appropriate training!
9.01 Adjusting the feed roller clearance (roller gap)
Before starting to seal, the gap between feed roller and sonotrode must be adjusted manually –
depending on the material to be sealed and the sealing parameters set. The adjustment can be made
from any of the sealing menus (see p. 23 ff.).
Switch on the machine.
Lower feed roller.
Adjust the roller gap with the adjustment
screw 1:
Turn towards +: gap will be extended.
Turn towards -: gap will be minimized.
After replacing the feed roller, the diameter (see section 11.06, p. 36) and the neutral point (see
section 11.07, p 37) of the feed roller must be set before adjusting the roller gap.
