Suction performance check
・
Limit continuous operating time of the vacuum pump to 30
seconds or less.
・
Operating the pump for 30 seconds or more continuously may
cause overheat of the engine, then wait until it cools down,
or
discharge water to cool down the engine.

After the vacuum is generated enough (about
-0.08
MPa (-12psi)), immediately return the priming lever
