Drive the actuator motor to the up (fully retracted) position using the Service Test Mode or a jumper to
the batteries.

Do not allow the
Tube
to
bottom out against the
Motor
Housing
.

Manually rotate the
Tube
toward the
Motor
Housing
until it bottoms out, then back the
Tube
out at least 1½ turn, but no more than
two full turns, in order to align the mounting
holes.
Service Tip:
Be careful not to
rotate the
Tube
prior
to installing the
Scrub
Deck Actuator
into the
machine. This can
cause the
Scrub Deck
Actuator
to get out of
adjustment.
