of 250 hours or every six months is recommended.
This recommendation has been made to help
ensure proper lubrication during operation and to
prolong engine life under typical operating
conditions. Oil Change Procedures

Engine Oil Specifications

Due to the variations in the quality and performance
of commercially available oils, Terex Heavy Duty
Diesel Engine Oil – 10W30 is recommended. If
Terex lubricants are not available, use a substitute
meeting the following qualifications:
- API CH-4 multi-grade engine oil

Hydraulic Fluid and Filter

The hydraulic fluid should be changed every 500
service hours, and the hydraulic filter should be
changed every 250 hours. Hydrostatic components
require extremely clean oil for long service life.
