Assembly
1. Remove all packaging material from the pump and its parts.
2. Thread the Lever Handle (1) into the Handle Bracket (2), and turn it clockwise
until it is tight.
3. Open all 4 Cover Clamps (17), by lifting their handles up from the bottom, and
letting their clamps fall away from the Drum Cover (5). Remove the complete
Drum Cover (5) and Pump (10) assembly, set these aside.
4. Wipe out the Grease Drum (9) with a clean, dry rag to remove any
contaminants that may be present.
5. Fill the Grease Drum (9) with up to 22 lbs. of bulk grease. Be sure to leave at
least 1” from the top of the Grease Drum (9) unfilled, to make room for the
pump and its components.
NOTE: Never put contaminated grease into the Grease Drum (9) as contaminants
may damage the pump or the mechanism the grease is eventually pumped into. If
grease is spilled onto the floor while filling, that grease should be discarded.
6. Place the Drum Cover (5) and Pump (10) assembly back onto the Grease
Drum (9), with the Follower Plate (8) resting on the grease.
7. Push the Drum Cover (5) down onto the top of the Grease Drum (9).This will
compress the Compression Spring (7), and will expel any air that might be
trapped in the grease.
8. Reattach all four Cover Clamps (17), by positioning the clamp over the edge
of the Drum Cover (5), and pressing the lever of the Cover Clamps (17) down
to lock them closed.Your Grease Pump is now ready for operation.

Steel Extension (14)
Operation
NOTE: This pump is designed for use with
petroleum based grease only. Do not use
this pump for oil or other low-viscosity
fluids, water-based materials, gasoline or
other flammable liquids, or corrosive
compounds. Do not use any materials
which may damage the steel, iron, brass or
nitrile rubber which make up the mecha-
nism of this pump.
NOTE: On first use, you will have to pump
several times until grease has filled the pump mechanism and the rubber hose.
Point the Steel Extension (14) and Coupler (12) into an appropriate waste recep-
tacle while pumping until grease is expelled from the Coupler (12).
WARNING: Never point the Steel Extension and Coupler toward any person or
animal while pumping. Expelled grease under high pressure may cause severe
injury.
NOTE: In the unlikely event that you are unable to get the grease to flow, it is likely
that there is air trapped in the grease which is interfering with the action of the
pump.To remedy this, open the Air Bleeder (16) by turning it counter clockwise a
few turns by hand. Do not remove the Air Bleeder (16) from the pump.With the Air
Bleeder (16) open, pump the handle until grease is expelled from the Air Bleeder
(16). Close the Air Bleeder (16) by turning it by hand clockwise, until hand tight. Do
not overtighten.
1. To operate the pump, attach the Coupler (12) to the grease fitting of the
equipment being serviced. Hold the Coupler (12) in a straight line with the
grease fitting on the machine, and ensure that the Coupler (12) is securely
fastened.
2. Place one foot onto the Foot Rest (11), and pump the Lever Handle (1).
Grease will flow from the pump into the machine being serviced.When the
machine is full, grease will begin to escape from the overflow port on the
machine.When you observe this, stop pumping.
3. To disconnect the Coupler (12), slightly tilt, twist and pull it off the grease
fitting.

Maintenance
1. When not in use, store the Steel Extension (14) in the vertical steel tube
attached to the side of the Grease Drum (9).
2. Protect the Coupler (12) from damage.Wipe it with a clean rag before each
use to prevent contamination of the grease being injected.
3. Store your Grease Pump in a clean dry place. Protect it from temperature
extremes. Do not expose this tool to corrosive environments.
4. If you observe any grease leaking from the Air Bleeder (16), Discharge Outlet
(15), or Coupler (12), check to be sure these parts are tightly installed.
5. Occasionally lubricate the pivot points of the Handle Bracket (2) and
Connecting Link (4) with a medium weight oil.
