Check the vent valve (2).

Note: If the reservoir is not properly vented, pressure will cause the wiper seal on the follower assembly inside the reservoir to fail when the reservoir is filled. Grease on the top side of the follower assembly may prevent the autolube system from functioning properly. Also, grease on the top side of the follower assembly may damage the autolube system.

Connect hose to port (4).

Pull out button switch (5) to the ON position and make sure that lube grease fill switch (6) is in closed state.

Fill the reservoir until the light activates on the button switch (5). Float switch (3) is tied to the button switch (5) and determines when the reservoir is full.

Note: The bulk capacity of the grease reservoir is 54 kg (120 lb).

Press the button switch (5) to the OFF position and make sure that lube grease fill switch (6) is in closed state.

The automatic lubrication reservoir provides lubrication for many components. There are fittings at the following locations: rear of machine, left side of machine and right side of machine.

If any of the remote lines become damaged, install a fitting in place of the remote line. Lubricate the item at the fittings until the remote line can be replaced.
