MAINTENANCE

WARNING: AVOID INJURY.
Read and understand the Safety
section before proceeding.
Proper maintenance can prolong the life of
unit. The Maintenance Schedule on Page 24
shows the recommended service schedule.
Your Gravely dealer can provide service and
adjustments to keep your unit operating at
peak efficiency. Contact an authorized engine
manufacturer's service center for engine
service.
More frequent service may be required due to
working conditions (heavy loads, high
ambient temperatures, dusty conditions, or
airborne debris).
See the maintenance instructions in the
Engine Manual for additional information.

service is due. Service time is measured for:

The service intervals preset into the hour
meter are:
• Hydraulic oil and filter: First 75 hours and

NOTICE: The preset engine oil services
intervals are normal recommended intervals.
