• Remove seal from grease gun cartridge and mount grease gun head back onto the barrel.
• Depress the air vent valve (fig. 2).
• Release the plunger rod using its tab, force the rod out and in a few times to eject air trapped in the grease via the air vent valve. When grease comes out of the valve, the air has been discharged.
• Pump the grease gun handle until grease flows continuously. If it does not, depress the air vent valve again and use the plunger rod to expel the trapped air.

4.3. Suction Loading
