Warnings

See the Dyna-Star HF and HP Pump Instruction manual
for additional warnings.

SKIN INJECTION HAZARD

High-pressure fluid from dispense device, hose leaks,
or ruptured components will pierce skin. This may look
like just a cut, but it is a serious injury that can result in
amputation. Get immediate surgical treatment.

Follow Pressure Relief Procedure in this manual,
when you stop dispensing and before cleaning, check­ing, or servicing equipment.

PRESSURIZED EQUIPMENT HAZARD

Over-pressurization can result in equipment rupture
and serious injury.

• A pressure relief valve is required at each pump
outlet.

• Follow Pressure Relief Procedure in this manual
before servicing.

Installation

Pressure Relief

Follow the Pressure Relief Procedure whenever
you see this symbol.

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 dispensing and
before cleaning, checking, or servicing the
equipment.

To relieve pressure in the system, use two wrenches
working in opposite directions on pump outlet fitting to
slowly loosen fitting only until fitting is loose and no
more lubricant or air is leaking from fitting as shown in
F

IG. 1.

PRESSURIZED ALUMINUM PARTS HAZARD

Use of fluids that are incompatible with aluminum in
pressurized equipment can cause serious chemical
reaction and equipment rupture. Failure to follow this
warning can result in death, serious injury, or property
damage.

• Do not use 1,1,1-trichloroethane, methylene chlo­ride, other halogenated hydrocarbon solvents or
fluids containing such solvents.

• Many other fluids may contain chemicals that can
react with aluminum. Contact your material supplier
for compatibility.
