Lift Assist Cylinder Lock-Up

When moving the raised planter more than a short dis-
tance, or over any paved surface, do not rely solely on
the lift cylinders to keep it raised. Install transport locks.

from their storage

positions. Do not store the locking pins on the empty
storage tabs.

Fully raise the planter (using both 3-point and lift
assist).

Remove any height adjusting blocks from the lift
assist cylinders.

4.

Install the transport locks on the cylinder rods

,

securing them with the same pins used for storage.

5.

Lower the lift assist cylinders onto the locks. Leave
the 3-point raised.
