units with fluid, as damage may occur. Do
not run the machine with the fluid below the
add mark.

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:
Use a summer filter when the temperature is
0°C (32°F) and above. Use a winter filter when the
temperature is 0°C (32°F) and below.
