Grounding

Grounding
The equipment must be grounded to reduce the risk of
static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.

manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before clean-
ing, checking, or servicing the equipment.

knob fully counterclockwise.
3. HTX2030 Air Spray Trigger Gun only: Pull gun
trigger to release pressure.
4. Turn prime/drain valve down to DRAIN position.
Fluid from drain valve can splash in eyes or skin and
cause serious injury. Keep hands clear of pressure
relief valve and always wear safety glasses.

pletely clogged or that pressure has not been fully
relieved after following the previous steps, cover the
connection at end of hose with a heavy rag and very
slowly loosen connection.
