Important Safety Instructions
Read all warnings and instructions in this 
manual and in the G1 Pump and USP Valve 
instruction manuals. Save all instructions. 

Warnings 
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The 
exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific 
risks. When these symbols appear in the body of this 
manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not 
covered in this section may appear throughout the body 
of this manual where applicable.
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper 
grounding, setup, or usage of the system can 
cause electric shock.
• Turn off and disconnect power at main 
switch before disconnecting any cables 
and before servicing or installing 
equipment.
• Connect only to grounded power source.
• All electrical wiring must be done by a 
qualified electrician and comply with all 
local codes and regulations.
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 spraying 
and before cleaning, checking, or servicing the 
equipment.
Relieve pressure in system using two wrenches working in opposite directions on pump element and pump 
element fitting to slowly loosen fitting only until fitting 
is loose and no more lubricant or air is leaking from fitting.
NOTE: When loosening pump element fitting, do NOT 
loosen pump element. Loosening pump element will 
change the output volume.
SKIN INJECTION HAZARD
High-pressure fluid from dispensing 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.
• Do not point dispensing device at anyone 
or at any part of the body.
• Do not put your hand over the fluid outlet.
• Do not stop or deflect leaks with your 
hand, body, glove, or rag.
• Follow the Pressure Relief Procedure 
when you stop dispensing and before 
cleaning, checking, or servicing equipment. 
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace 
worn or damaged parts immediately.
