Safety*
The assembly must be installed, maintained
and repaired exclusively by persons familiar
with the instructions.
Always disconnect power source
(electricity, air or hydraulic) from the
equipment when it is not being used.
This equipment generates high pressure.
Extreme caution should be used when
operating this equipment as material leaks
from loose or ruptured components can
inject fluid through the skin and into the
body. If any fluid appears to penetrate the
skin, seek attention from a doctor
immediately. Do not treat injury as a simple
cut. Tell attending doctor exactly what type of
fluid was injected.
Any other use not in accordance with
instructions will result in loss of claim for
warranty or liability.
• Do not misuse, over-pressurize, modify
parts, use incompatible chemicals, fluids,
or use worn and/or damaged parts.
• Do not exceed the stated maximum
working pressure of the equipment or of
the lowest rated component in your
system.
• Always read and follow the manufacturer’s
recommendations regarding fluid
compatibility, and the use of protective
clothing and equipment.
• Failure to comply may result in personal
injury and/or damage to equipment.
CAUTION
Do not operate equipment without
wearing personal protective gear.
Wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing pro-
tection used for appropriate conditions
will reduce personal injuries.
Failure to comply may result in light
personal injury.
WARNING
Do not allow any body part
to be trapped by equipment.
Body parts can be crushed
by subassemblies during
operation.
Failure to comply may result in death
or serious physical injury.
WARNING
Do not allow fluid to leak
onto floor when operating
equipment. If spill occurs,
clean any fluid on floor before continuing
operation.
Failure to comply may result in death
or serious personal injury.
WARNING
Do not use this equipment to supply,
transport, or store hazardous
substances and mixtures in accordance
with annex I part - of the CLP
regulation (EG /) or HCS 
CFR . marked with GHS,
GHS and GHS hazard pictograms
shown:
Explanation of signal
words for safety
NOTE
Emphasizes useful hints and
recommendations as well as
information to prevent property damage
and ensure efficient trouble-free
operation.
CAUTION
Indicates a dangerous situation that can
lead to light personal injury if
precautionary measures are ignored.
WARNING
Indicates a dangerous situation that
could lead to death or serious injury if
precautionary measures are ignored.
DANGER
Indicates a dangerous situation that will
lead to death or serious injury if
precautionary measures are ignored.
WARNING
Do not operate equipment
without reading and fully
understanding safety
warnings and instructions.
Failure to follow warnings and
instructions may result in serious injury.

The  Pump is used as the Pumping
Unit for a Centralized Lubrication System
having a Single Line Circuit of SL-, SL-,
or SL- Injectors. Dispenses grease up
through NLGI No. .
It is an air-operated, single-stroke pump
requiring air for both forward and return
stroke and discharges *. cu. in. of lubri-
cant into the circuit for each pump stroke
(Lubrication Cycle).
The total quantity of lubricant needed for
the lubrication cycle of the system must not
exceed the amount of lubricant discharged
per pump stroke.
To fill reservoir
Use a manual filler pump to fill reservoir
through the filler fitting in the pump body.
Attach coupler on delivery hose to filler fit-
ting. Stroke filler pump handle until lubricant
weepage is noted at air vent hole in the res-
ervoir (lower portion of follower must rise
beyond air vent hole to expel entrapped air
from lubricant).

NOTE
When filling the reservoir, caution
should be used as extreme pressure can
cause damage to reservoir and follower
assembly.

To prime system
Supply lines
After pump reservoir has been filled with
recommended lubricant, turn vent plug
counter-clockwise one complete turn and
operate pump until lubricant flows freely
from opening in vent plug to expel air pock-
ets trapped between the pump and the sup-
ply line connection. Tighten vent plug.
Remove all plugs in dead ends of the injector
manifolds and supply lines. Operate pump
until lubricant flows from any plug opening.
Close opening with plug. Continue operating
pump until lubricant flows from another
plug opening. Repeat this procedure until all
supply lines are primed and plug openings
closed.
Feeder lines
Fill each feed line with lubricant before con-
necting lines to outlet of injectors and bear-
ings. This will prevent having to cycle each
injector for every inch of feed line between
injector and bearing.
Injectors
Check each injector for proper operation.
Injector stem moves when injector dis-
charges lubricant to bearing. This may
require cycling system several times. After
checking injectors for operation, adjust
injectors for the volume required for each
bearing.

What to do if:
Pump loses prime
Check lubricant supply.
System fails to cycle
And calculated system planning has been
followed - Lubricant is leaking by packing of
 Check or the  Check. Failure of
injectors to cycle can also be caused by a
leak in supply lines. Examine supply lines
and connections.

Check air supply.
To clean line check
