Important Safety Instructions
Read all warnings and instructions in this manual and in the pump instruction manual included
with your system. 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.
FIRE AND EXPLOSION HAZARD
When flammable fluids are present in the work area, such as gasoline and windshield wiper fluid, be
aware that flammable fumes can ignite or explode. To help prevent fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources, such as cigarettes and portable electric lamps.
• Keep work area free of debris, including rags and spilled or open containers of solvent and gasoline.
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Ground all equipment in the work area.
• Use only grounded hoses.
• Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment
until you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
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.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including
eye injury, hearing loss, inhalation of toxic fumes, and burns. This protective equipment includes but is
not limited to:
• Protective eyewear, and hearing protection.
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment may stay pressurized or may become
pressurized by an automatic lubrication cycle initiated
by a lubrication controller. To help prevent serious
injury from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the Pressure
Relief Procedure before cleaning, checking, or
servicing the equipment.
1. Disconnect power to the lubrication controller.
2. If connected to an air supply, disconnect air supply
to pump module to ensure the system is depressurized.
3. Consult your pump manual for any additional pressure relief instructions related to your pump module.
• The amount of dispensed volume can vary
depending on external conditions such as lubricant temperature and back pressure from the
downstream connection.
4. When the injector has been adjusted for the proper
lubricant output, wrench tighten the stroke adjustment lock nut (7).
NOTICE
To prevent component failure, the adjustment nut (8)
must not be extended beyond the fully retracted
position of the piston (6). See F
IG. 1.
