ENGINE MAINTENANCE AND INSPECTION SCHEDULE
Routine maintenance is necessary for all mechanized products. Periodic maintenance contributes to the
product’s life span. The following maintenance chart provides guidelines for engine maintenance and in-
spection scheduled to be performed by you and/or by an authorized DEALER. The schedule should be
adjusted according to operating conditions and use.
The recommended lubricants have been formulated to protect bearings, gears and engine components.
They must be used to avoid damage caused by improper lubrication.
IMPORTANT: Schedules for rental operations, commercial applications or high hour use will require
greater frequency of inspection and maintenance.
