Replacing the Hydraulic Filter
Service Interval: After the first 100 hours—Change
the hydraulic filter and reservoir
hydraulic fluid when using any type
of fluid.
Every 250 hours—Change the hydraulic filter
and reservoir hydraulic fluid when using Mobil
1 fluid (more often in dirty or dusty conditions).
Every 500 hours—Change the hydraulic filter
and reservoir hydraulic fluid when using Toro
HYPR-OIL ™ 500 hydraulic fluid (more often in
dirty or dusty conditions).
Note:

Changing the hydraulic fluid unnecessarily
could damage the hydraulic system by
introducing contaminates into the system.
