Dixon 501 - Manual (Page 14)

FINAL PREPARATION
1. Remove battery from chassis.
2. Fill each cell with electrolyte (acid) to ring at bottom of fill cap.
3. Allow battery to sit for (10) minutes, re-check acid level and top off any
cells that are low.
4. Trickle charge battery using a charger of less than (6) amps until all cells
are gassing freely. Hydrometer readings may be taken, if desired.
5. Install permanent battery caps and wash any accumulated acid from battery
before re-installation on chassis.
6. Observe proper battery polarity when re-connecting leads on chassis. Always
connect positive lead first.
Engine Service:
1. Final preparation of engine should be completed using engine service manual
provided with mower.
Initial Start and Hydrostat Transmission Check:
1. Final hydrostat checks have been performed at the factory, however, it is
necessary to check that the pressure relief bypass on each hydrostatic
transmission is completely released before attempting to drive mower.
2. Each hydrostat has a bypass relief pin located at the bottom front of the
unit. A stop plate is provided to allow the mower to be rolled around
without complete servicing of the unit. To accomplish this, the stop
plate must be positioned to depress the bypass relief pin. If the stop
plate is depressing the pin, loosen the lock nut on the stop plate and
rotate the stop plate outward which will allow the pin to pop out to the
fully extended position. Tighten lock nut on stop plate at this point.
