Numatic NVD 750F Owner's Manual

NUMATIC - NVD 750F / SNTD 750
NOTE: As with all electrical equipment, care and attention must be exercised at all
times during its use, in addition to ensuring that routine and preventative maintenance is
carried out periodically in order to ensure its safe operation. In particular the electrical
supply cable and flexible hose should be regularly inspected by a competent person
and immediate action taken to rectify any faults found. Failure to carry out maintenance
as necessary, including replacement of parts to the correct standard, could render the
equipment unsafe and the manufacturer can accept no responsibility in this respect.
See the enclosed exploded drawings for correct replacement parts.

MACHINE COMPONENTS

Powerhead
The 2 bypass vacuum motors are housed within the epoxy coated steel head. To start
the vacuum, there is 1 switch mounted on the front of the handle assembly. The
powerhead is removed by lifting up on the 2 steel toggles and releasing the claws from
the rim of the powerhead.
The exhaust port of the vacuum is equipped with a screw on diffuser to divert the
exhaust airflow. This may be removed if required. Also it is possible to fit an exhaust
hose to divert the processed vacuum air to another area. For this it is recommended to
use the shortest 2" Numatic hose possible, and to increase the diameter to proprietary
exhaust hose as soon as possible to reduce back pressure.
