CHECK THE HYDRAULIC OIL LEVEL

WARNING!

To avoid hydraulic oil injection or injury, always wear appropriate clothing and eye protection when working with or near hydraulic system.

See Figure 3. Remove the Right Engine Access Panel (37) and look at the Gauge (A) on the side of the reservoir. If the oil level is below the minimum level, add 10W30 motor oil until the gauge reads between the minimum and maximum levels. Change the oil if major contamination from a mechanical failure occurs. SERVICE NOTE: Remove the small access panel (49) directly above the reservoir to add oil. This panel is held on by (2) wing nuts on the underside of the panel. The large Allan Head Plug (B) on the top of the reservoir is for adding oil.
