MAINTENANCE RECORD
Your Lil’ Thumper is designed to require only occasional
light maintenance. Attention to the following procedures
will significantly prolong the useful life of your pump.
1. Make a habit of carefully checking all nuts, bolts, fit-
tings, plugs, hoses and hose clamps daily to see that they
are secure.
2. Check drive chain alignment. If uneven sprocket wear
occurs, loosen the pump mounting bracket and move pump
and bracket accordingly. Keep the drive chain lubricated
with a good quality chain lubricant.
3. Keep the external surfaces of the pump clean. Dirt
and grease can cling to the pump in a heavy layer and may
cause an unnecessary heat build-up which can shorten
the life of your pump. A high pressure spray washer is
recommended to remove dirt and chemicals from the pump
and clutch assemblies after each use. Cover the vent hole
in the 1/4” breather plugs (located in the top of the drive
cases) so water does not enter the drive cases. Uncover
the breather plugs when washing is done.
4. Change the oil in the drive case of your pump annually.
This is done by removing the 1/2” fill plugs and the 1/4”
drain plugs and draining the oil. When all the oil has drained
out, replace the 1/4” drain plugs and fill the drive cases to
the bottom of the check plug hole with a good quality non-
detergent 30 weight oil as described in the “LUBRICATION”
section of this manual.
5. If chemical or water is found in the oil, the stackpack
glands may be leaking. Refer to the “PARTS BREAKDOWN”
section of this manual to replace these parts or see your
dealer for service assistance.
If replacement parts are required, order by part number
and description to insure prompt shipment.
6. Check the weep hole at the bottom front of the pump neck.
Any solution leaking there means that the front stackpack is
worn and should be replaced. Keep the airway in the drive
case breather plug clean. Remove the plug to clean. This
will keep dirt from falling into the drive case.
