Sundstrand Sauer Danfoss Series 15 Maintenance on Reservoirs
Maintenance Suggestions for your system.
If you have a sealed reservoir, the hydraulic fluid should be changed every 2000 hrs of operation.
Should it be an open reservoir, the hydraulic fluid needs to be changed every 500 hrs.
The reservoir needs to be free of any dirt, water, solvent, grease and any foreign matter. If it does have any of this in your reservoir, changing it will need to be more frequent.
Always use manufactured recommended hydraulic fluid.
A sealed reservoirs charge pump filter suggests it to be take out and replaced every 500 hrs.
Open reservoirs needs to be take out and changed every 100 hrs.
Also, the air breather on an open reservoir needs to totally replaced at every 500 hrs.
And without question, filters SHOULD always replaced with a new one when changing the fluid.
You need to check out your reservoir everyday. If you see water, note to see if it milky or cloudy look to it and if it has a foul smell (means intense heat).
Always use the correct hydraulic fluid for your unit.
