WARNING

Product Overview
313888F June 2019
Product Overview
HTX 2030 with Base Coat Pump
(257369)
The HTX 2030 Sprayer comes equipped with a Base
Coat Pump 24B321. Only water-based materials are to
be used with this configuration, such as:
•Smooth to heavily aggregated textures with silica
sand, perlite, vermiculite and polystyrene
•Smooth, medium, coarse and extra coarse textures
•Most materials with aggregates up to 2.5 mm (.100
in.) in longest dimension
When Base Coat Pump is Installed
Pump will only run when on/off switch is in ON position
AND:
•Pump control is rotated clockwise away from OFF
position, and either of the following switches are
also switched ON:
Prime Switch on pressure control box AND/OR
Applicator Switch near end of material hose
The pressure control will limit the sprayer to 1,000 psi
(69 bar), stopping the pump whenever pressure limit is
reached.
Flow rate is dependent on engine speed and the setting
of the pump control knob.
1. Flow 3 (fully clockwise) - allows the pump to run
continuously with minimal pulsation:
2. Flow 2 (near middle of the rotation) reduces flow
slightly by briefly interrupting pump:
3. Flow 1 (near counterclockwise end of pump control)
reduces flow more by interrupting pump longer:
4. OFF (fully counterclockwise) - stops pump com-
pletely:
5. Adjust engine speed to control flow rate of sprayer.
Start with the slowest speed possible for maximum
spray control. Different spray tip nozzle sizes can
also be tried.

a. Rotating knob fully clockwise allows sprayer to
reach maximum working pressure of 3300 psi
(228 bar, 22.8 MPa)
b. Settings below maximum will lower system
pressure
•Pump will run whenever system pressure is below
the setting of the pump control
•Sprayer will not respond to Prime switch or Applica-
tor switch when Top Coat pump is installed

Grounding
June 2019 313888F
Grounding
Ground sprayer with grounding clamp to earth ground
when flushing sprayer.
To maintain grounding continuity when flushing or
relieving pressure: Hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun/valve.
Pressure Relief Procedure
Applicator and Air Spray Trigger Gun
(Base Coat Pump)
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Turn engine OFF.
2. Turn on/off switch OFF and turn pressure control
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.
NOTE: If you suspect spray tip nozzle or hose is com-
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.
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.
ti3058a
This equipment stays pressurized until pressure is
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.
