PRIME AND DISCHARGE
･
While the engine is running with the cowl
removed, do not touch the rotating parts of
the pulley or belt.
This may cause
personal injuries.
･
If the pump could not prime water in 30 seconds, or could
not suck up water continuously by the pump during the
discharge operation, check the following :
✓
Is the tip of the suction hose completely below the water
surface?
✓
Is air sucked through the joint of the suction hose?
✓
Is the suction hose damaged?
✓
Does the vacuum performance of the priming pump
reduced significantly?
✓
Does the pump case keep vacuum?(No air leak from the
pump case.)
✓
Does vacuum leak occur when the pump is connected to a
suction hose of which the opening is capped?
Refer to “Chapter 16 TROUBLESHOOTING”.
