• Keep small vent holes open.
• Recharge at 6-10 amperes for 1 hour.
NOTE: The original equipment battery on
your tractor is maintenance free° Do not
attempt to open or remove caps or covers.
Adding or checking level of electrolyte is
not necessary.

NOTE: Although multi-viscosity oils (5W30,
10W30 etc.) improve starting in cold weather,
the oils will result in increased oil consumption
when used above 32°E Check your engine
oil level more frequently to avoid possible
engine damage from running low on oil.
Change the oil after every 50 hours of opera-
tion or at least once a year if the tractor is
not used for 50 hours in one yean 19
