Wanner High Pressure Grease Gun (32391.11) Instructions & Troubleshooting

Wanner High Pressure Grease Pump

Attention: Turn Pressure Gauge into correct position before achieving pressure.



  1. Open the Air Relief Screw (35591.00). Turn screw to the left.

  2. Turn the Handle with the Piston Rod; pull back firmly and lock it on to the end cover (38013.00).

  3. Turn the Cylinder (38195.00) to the left to unscrew it from the Gun Head (33731.00). Only remove the end over (38013.00) from empty lubricator for cleaning purposes.

  4. Remove the empty grease cartridge. By operating the Piston Rod the cartridge gets thrown out automatically. Do not forget to recatch.

  5. Insert New Cartridge as follows:

    1. Remove the loose rear cap of the grease cartridge.

    2. Insert the open end of the grease cartridge into to the Cylinder (38195.00).

    3. Remove the second cap of the grease cartridge with a screw driver or knife.

  6. Screw together the Cylinder (38195.00) and the Grease Gun Head (33731.00).

  7. Pull the Handle with the Piston Rod out of the catch and let it slide into Cylinder (38195.00).

  8. Once grease flows constantly out of the side hold of the Air Release Valve (35591.00) then close the valve.

  9. Check if the Pressure Relief Screw (33773.00) is closed. The High Pressure Gun is now ready to use.


To Produce Pressure

  1. Connect the Hydraulic Connector (36590.00) with the High Pressure Hose (35143.00) onto the high pressure nipple. (Make sure that the nipple is clean!)

  2. Check if Pressure Relief Screw (33773.00) is closed.

  3. Turn the Pressure Gauge (83746.01) to the required position.

  4. Operate the Lever (33707.00) until the Pressure Gauge (83746.01) indicates the required pressure.


To Release Pressure

  1. Turn the Pressure Release Screw (33773.00) to the left and wait until the pressure is released. Never unscrew it totally, as the Valve Ball (82008.00) may get lost.

  2. The grease will go directly back into the Cylinder (38195.00).

  3. Remove the Hydraulic Connector from the high pressure nipple by tilting it sideways and slightly turning it.

  4. Close the Pressure Release Screw (33773.00) again.

Important: It is absolutely necessary to follow these instructions, otherwise the Connector or the nipple may be damaged.
