FREEZE PROTECTION
Follow all the steps for normal shut-down
and storage. Flush the cleaning system with
a 50% antifreeze and 50% water solution
using one of two methods:
Method One
Tip the unit on end exposing inlet garden
hose fitting. Remove screen filter from fitting
and pour in approximately 1/2 cup of
antifreeze and water mixture. Turn on unit
while pouring the
mixture in to allow
circulation of
antifreeze. Turn
unit off as soon
as all solution has
been poured into
the system.
Method Two
Attach a short garden hose (not to exceed
four feet) to inlet fitting on pump and put
other end into the antifreeze and water mix-
ture. Turn the unit on until mixture flows out
of the discharge fitting. Then shut unit off.
LUBRICATION
Keep crankcase filled to proper level (11 oz.
capacity) with Cat Pumps special formula
Premium ISO 68 Grade Non-Detergent
Hydraulic oil. Cat Pumps oil contains anti-
wear and anti-rust inhibiting additives for
maximum protection and cool running. Do
