4.11 Lubricating Connecting Rod Bearing
See Graphic: wc_gr003451
Grease connecting rod bearing once a week or every 25 hours of
operation.
Use a hand operated grease gun. Add grease through grease fitting
located behind access hole (j) provided on front cover.
4.12 Cleaning Pump
See Graphic: wc_gr003451
When pumping heavy sludges or water containing large amounts of
dirt and solids, clean the pump often. If allowed to sit in the pump and
dry, these materials will harden and could damage the valves or
diaphragm inside the pump the next time it is used.
When cleaning pump:
4.12.1 Pump clean water through pump for a few minutes after each use to
flush dirt from inside pump and hoses.
4.12.2 Remove dirt from between engine cooling fins to prevent them from
clogging up. This will prevent engine from overheating.
4.12.3 Remove front cover (k) and clean dirt and grease build-up from
connecting rod and inside of front pump cover.
