WARNING
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.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment
until you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information
about your material, request MSDS forms from distributor or retailer.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your distributor for information.

Warnings
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:
• Protective eyewear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
• Hearing protection

Pumping Rate
During the pump suction stroke an amount of oil equal
to the pump displacement is drawn through the drip tube
into the sight well. The amount of fluid in the site tube
indicates the pumping rate.
NOTE: Allow sufficient time to insure an accurate rate
indication. The drip tube flow rate is only accurate after
the pump has operated long enough to stabilize the
pressure inside the sight well.

Service
Pressure Relief Procedure
The equipment stays pressurized until pressure is
relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the dispenser, or
splashing fluid, follow this Pressure Relief Procedure
whenever you:
• Check, clean or service any system equipment.
• Install or clean fluid nozzles.
1. Disconnect power supply.
2. Open any bleed-type master air valves and fluid
drain valves in the system.
Service
A
3. Leave drain valves open until you have completed
repairs and are ready to pressurize system.
NOTICE
• All installation, maintenance, and repair work
must be completed by qualified personnel.
• If the correct pumping rate is maintained, no service is required other than periodic replenishment of the reservoir.
Service Instructions
1. Check lubricator operation by observing the drip
tube. If the sight glass well pumps dry or no flow is
observed, check the following points until the cause
is determined and corrected.
• Check the vent plug (A) for proper sealing. Any
knicks or cracks in the rubber plug will cause an
air leak into the sight glass (F
IG. 9).
FIG. 9
• Check shaft rotation. If the lubricator shaft is not
rotating, determine the cause and repair as necessary.
• Check oil level and viscosity. Be sure the reservoir is filled with oil, and if necessary heat the
reservoir to maintain viscosity at the correct
level for the desired flow.
• Check pump priming. If necessary, prime the
pump in accordance with the operating instructions, page 5.
• Check the feed adjustment (C, F
page 6) and adjust if the pumping rate is too
low.
IG. 7 and FIG. 8,
• Check the actuating linkage for proper operation. If defective, isolate the broken part and
repair or replace as required.

Service
‘
2. If items listed in step 1 are not the cause, check the
pump assembly. The following items should be
checked before removing the pump assembly from
the cover.
• Check the sight glass for inward leakage due to
a crack in the sight glass, improper sight glass
seating, or a defective o-ring. Repair as
required (F
IG. 6, page 6).
• Check for an obstruction in the drip tube and
remove if found.
• If these steps do not isolate the malfunction:
a. Relieve system pressure, page 7.
b. Disconnect the discharge tubing (E) (F
c. Remove 4 screws (F) holding pump to cover
IG. 10).
(F
d. Remove the pump assembly (G) (F
NOTE:
• Keep a spare pump on hand for use during
emergencies and when the pump is being
repaired.
• If a spare pump is available, it will not be necessary to stop the equipment the lubricator is
installed on or to empty the reservoir.

• If the sight glass fills with lubricant proceed as
follows:
a. Remove system pressure, page 7.
b. Remove vent plug (A) (F
IG. 11).
c. Allow the lubricant to pump down to the
proper level.
8 311842C
Service
d. Replace vent plug (A).
The pump should operate normally.
• If the sight glass continues to fill with lubricant:
a. Check all terminal check valves for proper
operation.
b. Relieve system pressure, page 7.
c. If valves are operating properly, disconnect
the discharge tubing (E) (F
IG. 10)
d. Remove 4 screws holding pump to cover
(F
IG. 10, page 8).
e. Remove pump assembly.
f. Clean pump assembly.
g. Reinstall pump assembly to cover and check
operation.
• When the unit is operating the sight level will
vary depending on temperature variations.
a. If the level falls to less than 1/4 inch above
the sight glass flange, add lubricant to the
proper level (3/8 inch below the discharge of
the drip tube) through the vent hole.
b. If the level is too high, remove the vent plug
and allow the unit to pump down before
replacing the vent plug.
Other servicing that may be required is listed below:
• Clean lubricator periodically to eliminate contamination that may have occurred in the oil. To accomplish
this, remove all pumping units and clean the pumps
and reservoir by brushing loose all foreign matter,
dipping in solvent and blowing dry with compressed
air.
• If external leakage is observed, determine the
cause (loose bolts, defective gaskets, or seals) and
repair as required.
3. If the sight glass still fills with lubricant it may be
caused by temperature variation.
• When the unit is not operating:
a. Relieve system pressure, page 7.
b. Remove vent plug (F
IG. 11, page 8).
c. Allow lubricant to pump down to the proper
level.
d. Replace vent plug.
The pump will now function properly. The
sight glass may fill with fluid without affecting
the operation of the lubricator as long as the
drip tube remains above the lubricant level to
show the rate of pumping.
