.2% Check battery condition weekly or after every 50
hours of operation. Keep terminals and entire battery
case clean because a dirty battery will discharge
slowly. To clean the battery, wash the entire case with
solution of baking soda and water. Rinse with clear
water. Coat the battery posts and cable connectors
with Grafo 112X (skin-over) grease (Toro Part No.
505Ć47) or petroleum jelly to prevent corrosion.
Inspect air cleaner and hose periodically to maintain
maximum engine protection and to ensure maximum
service life.
Assure hose between air cleaner and carburetor is
clamped securely in place. Replace the hose if it is
cracked or punctured.
Check air cleaner body for dents and other
damage which could possibly cause an air leak.
Replace a damaged air cleaner body.
Be sure dust cap is sealing around bottom of air
cleaner body.
Mounting screws and nuts holding air cleaner in
place must be tight.
Inlet cap must be free of obstruction.
Inspect the dust cup and rubber baffle once a week or
every 50 hours operation. However, daily or more
frequent inspection is required when operating
conditions are extremely dusty and dirty. Never allow
dust to build up closer than one inch (25 mm) from the
rubber baffle.
.2% If conditions are extremely dusty and dirty, begin
by checking dust cup and baffle after each day's
operation to establish approximately how long an
interval passes before dust cup should be emptied.
Base further maintenance requirements on this figure.
These conditions may be particularly prevalent if the
rear discharge cutting unit is attached.
