VHC200
When several supporting platforms are provided, the
supporting platform to which the machine is anchored
must be handled with a forklift truck that can provide
adequate capacity. Then unpack the machine by laying
it down on a flat and horizontal surface that can provide
adequate capacity for the vacuum cleaner weight.
Setting to work - connection to the pneumatic
system
■ Make sure there is no evident sign of damage to
the machine before starting work.
■
Before connecting the machine to the pneumatic
supply, make
condensate-free air at the pressure indicated in
this manual (see technical data).
■
Regularly check there are no signs of damage,
excessive wear, cracks or ageing on the connecting
hose.
When the device is operating, do not:
■
Crush, pull, damage or tread on the connecting
hose.
■ Only replace the supply hose with one of the same
type as the original.
Those responsible for plant safety must ensure that:
■ Prevent any improper use or manoeuvre.
■ Make sure that the safety devices are not removed or
tampered with.
■ Check that all maintenance operations are regularly
performed;
■ Make sure that no machine part (couplings, holes, etc.) is
modified to attach additional devices;
■ Make sure that only original Nilfisk spare parts are used.

Supply pressure adjustment
The machine is equipped with a pressure governor only in case
the pressure governor optional has been purchased.
CAUTION!
If the adjustment procedure below is not properly
respected in each step or if the knob is forced
excessively in the direction of the maximum pressure
(clockwise), there is a risk of damage to the device and
the operator's safety can be compromised.
1. Adjust the pressure as required, according to the
compressor performances.
2.
In order to ensure proper performance of the machine,
check that the supply piping diameter is adequate, that is
to say not less than a nominal diameter of 14 mm.
3. Connect the machine to the air supply, then open the on/
off valve.
4. Adjust the supply air pressure as follows:
- Turn the pressure regulator knob in the direction of the
minimum pressure (counter-clockwise) up to the limit
switch (regulator closed)
- Turn the air regulator knob in the direction of the
maximum pressure (clockwise) until it reaches the desired
pressure, and check that it remains stable for at least 3
minutes; press the knob to lock it.
If the clockwise rotation reaches the end of the stroke without
having reached the desired pressure, and the conditions in
point 1 and 2 are met, set a lower supply pressure (see
table 1) and repeat the procedure starting from step "a".
