For your Yale GLP110MG forklift, the hydraulic system typically uses ISO VG46 hydraulic oil or John Deere JDM J20C fluid. Both meet the required cleanliness specs and are commonly used in this series.
Now, if you're doing a fluid change or flushing the system (like after switching types), make sure to follow the proper cross-contamination cleaning procedure — it's a bit involved, includes filter swaps and fluid cycling, but it’s all outlined in the service manual.
If you want exact service steps, oil volume, filter part numbers, and maintenance intervals, this repair manual will have all of that covered in detail 👍🏻
