MACHINE OPERATION

Picking Up Dry Substances
Before picking up dry substances, the bag-type filter should
always be installed in the tank. It is then easy to dispose of
the material picked up and the service life of the main filter
element is significantly increased.
WARNING: Inflammable substances must not be
picked up with the machine!
After picking up liquids, the filter element is damp. Damp
filter elements can clog more quickly when dry substances
are picked up. For this reason, the filter element should be
dried or replaced before picking up any dry substances.
Picking Up Liquids
For both wet and dry applications be sure to leave the
cartridge filter and the cloth filter in place around the float
cage. Also be sure to frequently clean the filters. This is
especially true when the vacuum is being used with
strippers and wax.
Daily Maintenance
CAUTION: Strippers and some detergents produce
foam which will damage the vacuum motors. The
vacuum float shut-off may not be sensitive to all
foams. Be sure to check that the tank is not filling
with foam. Use a defoaming agent to avoid pulling
foam through the vacuum motor. Should the vacuum
motor become wet, remove source of overflow and
immediately run vacuum motor open to purge the
motor dry. Both the cartridge filter and the cloth filter
should be rinsed and dried to remove stripper or wax.
Do not allow stripper or wax to dry in the filters, as
this will adversely affect performance.
1. Drain and rinse tank and remove head assembly to
allow drying.
2. Remove, rinse, and clean filters and allow to dry.
3. Inspect the power cord and hoses for damage.
WARNING: Inflammable liquids must not be picked up
with the machine!
Switching On The Machine (CTV 7, 15, 20)
Turn the switch to position "I" .
Switching On The Machine (CTV 7 AS)
Two operating modes are possible.
1. Switch position "I":
The machine motor starts immediately.
2. Switch position "auto":
The machine motor starts only when the tool con-
nected to the appliance plug socket is switched on.
CAUTION: Before turning the switch to position
"auto", ensure that the tool connected to the appli-
ance plug socket is switched off.
The motor speed and thus the suction power can be varied
at the suction force regulator. This permits a precise
adaptation to different substances to be picked up.
