Engine Oil
The engine was lubricated for test at the factory.
However, always check the lubrication level before
startup.
Consult the manual accompanying the engine,
and change the oil filter periodically as indicated. If
operated under extremely dusty conditions,
change the filter more frequently.
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-belts 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.
Drive Belt
Check the drive belt regularly for excessive wear
and proper tension. Refer to the separate Mainte-
nance and Repair manual for belt replacement
and adjustment procedures.
COLD WEATHER PRESERVATION
(All Models)
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.
