WARNING

SKIN INJECTION HAZARD

High-pressure fluid from dispense valve, 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 dispense valve at anyone or at any part of the body.

• Do not put your hand over the end of the dispense nozzle.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Follow Pressure Relief Procedure in this manual, when you stop dispensing and before cleaning,

checking, or servicing equipment.

MOVING PARTS HAZARD

Moving parts can pinch or amputate fingers and other body parts.

• Keep clear of moving parts.

• Do not operate equipment with protective guards or covers removed.

• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,

follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.

SUCTION HAZARD

Never place hands near the pump fluid inlet when pump is operating or pressurized. Powerful suction could cause serious injury.

BURN HAZARD

Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:

Operation

Oil Level

FIG. 2

• Install each pumping unit with a high pressure check valve in the discharge line adjacent to the pump discharge connection so that pump assembly may be removed from reservoir without loss of lubricant in lines (F

• Install a second of these valves at the point of lubrication to prevent line drainage and feedback of system pressure to pump (F

IG. 1).

1. Remove vent plugs (A) located on the top of the pump sight glasses to allow lubricant to rise in the drip tube to the level of the oil in the reservoir and reduce the priming required at start up (F

2. Completely fill the lubricator reservoir with clean filtered lubricant.

IG. 2).

Operation

NOTE:

• Three sight glasses (B) are provided in the reservoir at various levels to permit observation of fluid level (F

IG. 3).

• Oil level should not be allowed to drop below the bottom sight glass.
