370 OPERATION
CAUTION
DO NOT operate the vehicle if the
plungers are not fully engaged and the
trailer landing gear is not fully retracted.
Doing so may cause damage to the tractor,
trailer and landing gear.
Visually check to see that the slide plungers are fully engaged. It may be necessary to
leave the trailer brakes locked and to move the tractor slightly to engage the slide plungers
into the rail.
Wind up the trailer landing gear to its fully retracted position.
