minutes.

Insert flexible oil

return hose into

Proceed with normal

operations.

Disconnect flexible oil return

hose. Make sure it is cool before
handling. Try blowing air through

the hose.

Can you blow

air through it?

Submerge hose in very hot water,

keeping the water out of the hose.

Water in the hose will cause severe
