Reverse the PTT motor leads between
the battery terminals when the tilt rod
fully extends and then reverse them
again when it fully compresses. Repeat
this procedure so the tilt rod goes up
and down several times.
Check the fluid level again, add fluid if
necessary, and then extend and com-
press the tilt rod several times as
explained above.
Repeat these steps until the fluid
remains at the proper level.
