Change oil initially after 50 hours operation and every 800
hours, or yearly. Use high-quality SAE 80-90 gear lube as
replacement. Check oil if leakage is noted.
To check the oil level:
1. With the machine on level surface, position the
wheel so the check/drain plug is at either the three
or nine o'clock position (Fig. 50).
1. Check/drain plug (3 or 9 o'clock position)

To Drain Gear Oil:
1. With the machine on level surface, position the
wheel so the check/drain plug is at the lowest

BATTERY SERVICE

IMPORTANT: Before welding on the machine or
performing service to the electrical system, disconnect
the negative (–) battery cable from the batteries to
prevent damage to the electrical system.
Check the battery cables and connections every 100 hours
and check the batteries with a hydrometer every 500 hours
operation. Keep the terminals and the entire battery case
clean. Clean the batteries with a solution of baking soda and
water, then rinse with clear water. To prevent corrosion, coat
the battery posts and cable connectors with Grafo 112X
(Skin-over) grease, TORO Part No. 505-47.
CAUTION
Wear safety goggles and rubber gloves when working
with the batteries. Charge batteries in a well-ventilated
place so the gases produced while charging can dissipate.
Since the gases are explosive, keep electrical sparks and
open flames away from the batteries. Do not smoke.
Nausea may result if the gases are inhaled. Unplug the
charger from the electrical outlet before connecting to or
disconnecting charger leads from the battery posts.
1. Unlatch, raise and prop the hood open. Unlatch and
remove the left engine side panel.
