Abstract
A support for manual grease guns has a base and lever-restoring mechanism. Grease guns conventionally have a pumping head with a barrel and lever joined thereto for cycling through pumping and restoring strokes between restored and depressed extremes. The restored extreme has the lever and barrel flared apart. Conversely, since the pumping stroke closes the flare, the depressed extreme has the lever brought alongside the barrel. The base has ground-engaging feet as well as clamps for clamping the grease gun tightly by the barrel, preferably with the lever projecting away for pedal-style depression in a generally vertical plane by a user stepping on it. The lever-restoring mechanism links the lever to the base, and yields under the user's step while the lever moves through pumping strokes, but restores the lever toward the restored extreme therefor as soon as the user takes his or her step off the lever.
