MAINTENANCE
Cylinder Lubrication Box
1. The lubrication level should be checked every day prior
to pumping and maintained at a height of 5 inches or
about 1/2 the concrete cylinder height. We recommend
using a 30-weight motor oil.
2. As the rubber piston cups naturally wear, fine cement
particles will accumulate in the box. Once the concrete
paste reaches a height of about 1/2 inch from the
bottom of the box, drain and clean the lubrication box.
Cleaning the Lubrication Box
1. Remove the top cover and the drain plug (Figure 51)
located at the bottom of the box and fully drain the
inside of the box.
2. Once the box is drained, start the engine and stroke
the cylinder (keep hands out of box) ten to fifteen times.
3. While stroking, spray water inside of the box to
thoroughly clean out all contamination (Figure 51).
4. When the box is clean, replace drain plug, add new
lubrication and install the top cover.

NOTICE
When using the pump during freezing conditions,
completely drain the lubrication box and cover the hopper
after pumping. Frozen liquid will restrict the piston travel
and cause severe damage to the pump.
WARNING
ALWAYS
follow lock out/tag out procedures before
checking lubrication level. Stop the engine and remove
the engine starter key. The possibility exists of severe
bodily harm when hands are placed inside.
