Maintenance Notes:
1)
Initial 500 hours only. Follow regular intervals thereafter.
2)
Change oil yearly if operating under 8000 h. Lubricant may require more frequent changes depending on operating environment and running
conditions. For oil life versus operating temperature see chart on page 31.
3)
Do not tamper with safety valve setting - it is factory set - only check operation! Tampering will void warranty and result may cause severe injury or
death.
4)
Replace as necessary or every 5 years.
5)
Visual check weekly. Re-tension and re-align 50 hours after belt change. Check tension and alignment every 500 hours thereafter. Change belts
every 4,000 hours or as needed. Refer to the FS-Curtis Technical Bulletin #W 20151213-TB003 for detailed instructions on belt replacement, ten-
sioning, and pulley alignment.
*
The maintenance intervals described herein are for normal operating condition in clean and well ventilated environments. Frequency of intervals will
increase for non-standard environments. Please contact your authorized FS-CURTIS distributor for more information and recommendations.
