Do not operate engine above 1000 rpm during warm-up until
OIL PRESS gage indicates 25 to 30 psi (172 to 207 kPa) at
800 to 1000 rpm. OIL PRESS gage should indicate 50 to 70
psi (345 to 483 kPa) when engine operates at 1800 to 2100
rpm. Lack of lubrication may damage engine.

Run engine at 800 to 1000 rpm for about three minutes.
