1. Remove the drain plug (Figure 28) at the bottom of the oil
tank with a 6 mm hex wrench and drain the hydraulic oil.
2. Clean the filter with light oil.
3. Reinstall the drain plug to the oil tank. Apply seal tape or
Roctite #575 to thread portion.

period of time, store in cool dry place and check the
battery charge level every month to maintain the
performance of the battery.
