Ryobi P3410 Operation Manual - Page 8

OPERATION  Turn the grease tube counterclockwise to loosen and remove.  With the grease tube pointed up, grab the grease tube handle and move it away from the narrow slot.  Slowly allow the grease tube handle to move forward and eject the grease cartridge (not included). LOADING GREASE FROM A BULK CONTAINER See Figures 6 - 9, page 12. The grease gun can be loaded from a bulk container either directly or through a filler pump. To load directly from a bulk container:  Lock the switch trigger in the "off" position and remove the battery pack.  Turn the grease tube counterclockwise to loosen and remove.  Hold the grease tube firmly and turn the plunger assembly counterclockwise to loosen.  Remove the plunger assembly from the grease tube.  Use a clean dry cloth to remove any old grease from inside the tube.  Slide the plunger assembly back into the grease tube and rotate clockwise to secure.  With the grease tube handle pushed all the way in, submerge the open end of the grease tube into the bulk container.  Slowly pull the spring-loaded grease tube handle completely out to suction grease into the tube. Then move it to the side into the narrow slot to lock it into place. NOTE: To prevent air pockets from forming inside the grease tube, keep the open end of the tube completely submerged and away from the surface.  Remove the grease tube from the bulk container.  Use a clean dry cloth to remove excess grease.  Place the grease tube back onto the grease gun and rotate clockwise to secure. NOTE: Be careful to avoid cross-threading, which can cause the grease tube to leak during use.  Grab the grease tube handle and move it away from the narrow slot.  Slowly allow the grease tube handle to move forward and into the grease tube. NOTE: After the grease is loaded, use the purge valve to purge any air trapped in the grease tube. For more details, see Using the Purge Valve later in the manual. To load from a bulk container using a filler pump and low pressure coupler:  Lock the switch trigger in the "off" position and remove the battery pack.  Turn the grease tube counterclockwise to loosen and remove.  Remove the plunger assembly as described earlier.  Use a clean dry cloth to remove any old grease from inside the tube.  Connect the plunger assembly to the grease tube.  Place the grease tube back onto the grease gun and rotate clockwise to secure. NOTE: Be careful to avoid cross-threading, which can cause the grease tube to leak during use.  Locate the fill plug near the base of the tool.  Using a hex wrench, loosen and remove the fill plug from the bulk fill port. Store the fill plug for later use.  Install a 1/8 in. low pressure coupler (not provided) into the fill port. NOTE: Ensure that the coupler (not provided) is compatible with the grease gun and the filler pump (not provided). If the coupler is not compatible or if it fits improperly, the grease may not load correctly. WARNING: NEVER install a high pressure coupler into the bulk fill port. Using the wrong type of coupler could allow too much pressure to build inside the grease gun. Excessive pressure could cause parts of the tool to leak or burst and can lead to serious personal injury.  Slowly pull the grease tube handle out while rotating it counterclockwise to disengage it from the rest of the plunger assembly. NOTE: Do not move the handle inside of the narrow slot.  Once the handle is disengaged, gently move it back into the grease tube.  Attach the low pressure coupler (not provided) on the grease gun to the low pressure coupler on the filler pump (not provided). NOTE: The couplers are designed to fit loosely together and are not meant to form a tight seal. This design prevents the grease gun from being overfilled.  Using the filler pump (not provided), load grease into the unit until the grease tube handle extends about 8 in. NOTE: If the handle does not extend, it may not be disengaged from the rest of the plunger assembly. Disengage the handle and try again. 8 - English
