SERVICE DATA
REGULARLY REPLACE THE HYDRAULIC
OIL
When a large volume of oil is used in one-
way for the attachments, such as snow
removing equipment and lawn mowers, the
oil deteriorates more quickly than that used
for a usual operation. Be sure to replace the
hydraulic oil and the return filter elements.
• Failure to replace these in time can lead to
damage to the machine and the
attachment hydraulic system. To prolong
the service life of the hydraulic devices,
properly replace the hydraulic oil and the
return filter elements according to the table
below.
• When replacing the hydraulic oil, clean the
suction strainer.
When the operating ratio of snow removing
equipment or lawn mower is 100%.
