rect level (see LUBRICATION in the Maintenance
and Repair Manual). Bearing overheating can also
be caused by shaft misalignment and/or excessive
vibration.
When pumps are first started, the bearings may
seem to run at temperatures above normal. Con
tinued operation should bring the temperatures
down to normal levels.
Air Compressor
The air compressor was lubricated for test at the
factory. However, always check the lubrication lev
el before startup.
Check the compressor V‐belt regularly for exces
sive wear and proper tension. Refer to the manual
accompanying the air compressor for v‐belt ad
justment procedures.
Consult the manual accompanying the air com
pressor and preform all duties and checks as indi
cated.
COLD WEATHER PRESERVATION
In below freezing conditions, drain the pump to
prevent damage from freezing. Also, clean out any
solids by flushing with a hose. Operate the pump
for approximately one minute; this will remove any
remaining liquid that could freeze the pump rotat
ing parts. If the pump will be idle for more than a
few hours, or if it has been pumping liquids con
taining a large amount of solids, drain the pump,
and flush it thoroughly with clean water. To prevent
large solids from clogging the drain port and pre
venting the pump from completely draining, insert
a rod or stiff wire in the drain port, and agitate the
liquid during the draining process. Clean out any
remaining solids by flushing with a hose.
