CAUTION

If crankcase pressure is exces-

sively high, this pressure may

exceed the capacity of ma-

nometer. To prevent blowing

liquid out of manometer, dis-

continue test if liquid level

approaches limits of manome-

ter scale by closing manometer

tube connector.

Start engine and operate at 2500 RPM, FULL

LOAD. Slowly open manometer tube

connector (1), connected to nonmetallic

tubing (6), while carefully observing liquid

level in manometer tube.

NOTE

. A manometer measurement is the sum of the displacements from zero of the two

columns of liquid. The value expressed is in inches of water.

●

For model 5063-5299, crankcase pressure must not exceed 0.9 inch of water at 2500

RPM, FULL LOAD.

●

For all except model 5063-5299, crankcase pressure must not exceed 3.0 inches of

water at 2500 RPM, FULL LOAD.

When manometer tube connector (1) has been opened one full turn,

manometer scale.

Stop engine by moving governor stop lever to NO FUEL position.

Disconnect hose (6) and remove coupling half (5).
