which is a deadly poison and it causes
severe burns.
WHAT CAN HAPPEN
•If you carelessly drink electrolyte you could
die or if it gets onto your skin you will be
burned.
HOW TO AVOID THE HAZARD
•Do not drink electrolyte and avoid contact
with skin, eyes or clothing. Wear safety
glasses to shield your eyes and rubber
gloves to protect your hands.
•Fill the battery where clean water is always
available for flushing the skin.
•Follow all instructions and comply with all
safety messages on the electrolyte container.
1. Remove the battery from the tractor (refer to
Removing the Battery in your tractor Operator’s
Manual).
Note: Never fill the battery electrolyte with
the battery installed in the tractor.
2. Remove the filler caps from the battery. Slowly
pour electrolyte into each cell until the
electrolyte level is up to the lower part of the
tube (Fig. 3). Use an electrolyte with a specific
gravity of 1.265.

Checking the Wiring and
Fasteners
•Inspect the tractor for any loose electrical
connections and secure them as required. Check
the wire routing to make sure moving parts do
not interfere with wires and cause a short.
•Assure all fasteners are tight.
Burnishing the Clutch
The following break–in procedure must be performed
as part of predelivery service or when a new clutch is
installed.
Note: There must be a PTO driven
attachment installed to provide a load
in order to burnish the clutch facings
properly.
1. Run the engine at full throttle and engage the
clutch bringing the load to full speed. Then
disengage the clutch.
2. Let the load come to a full stop, then engage
again.
