Cylinder lubrication box: Warning

Before checking lubrication level, stop the engine and remove
the engine starter key. We recommend using soluble type oil
(water & oil mixture). The oil level should be checked everyday
prior to pumping. The oil level should be maintained at a height
of 5 inches or about ½ the concrete cylinder height.

Important notice! During freezing temperature after pumping,
completely drain the water box and cover the hopper. Frozen
liquid will restrict the piston travel and cause damage to the
pump.

As the rubber piston cups naturally wear, fine cement particles
will accumulate in the box. Once the concrete paste reaches a
height of about ½ inch from the bottom. The box should be
drained and cleaned. To clean, remove the drain plug located
at the bottom of the box. Once the box is drained, start the engine
and stroke the cylinder (keep hands out of box) ten to fifteen
times. While stroking, spray water inside of the box to thoroughly
clean out all contamination. When the box is clean replace drain
plug, add new lubrication and install the top cover.

Any questions regarding the above mentioned procedure,
please call the Mayco Service Department: 1-800-30-MAYCO.
