This Maintenance Interval Chart was developed to match the Service and Storage chapter of this manual. Detailed
information on each Service Procedure is in the Service and Storage chapter. A Maintenance Log follows the
Maintenance Interval Chart for recording the maintenance procedures performed. Recording the 10-Hour (or
Daily) service procedures is impractical and is therefore not recommended.
IMPORTANT: Under severe operating conditions, more frequent service than the recommended inter-
vals may be required. Users must decide if the severity of their operation requires more frequent service
than normal.
