LUBRICATION
A periodic coating of light lubricating oil to pivot points

wheel fittings, will help to prevent rust and assure
that wheels, casters and pump assemblies move
freely. To help ensure trouble free operation, an in-line
air dryer and oiler is recommended.
CLEANING
Periodically check the pump piston and ram for signs
of rust or corrosion. Clean as needed and wipe with
an oily cloth.
