3.10 Hydraulic System
1. Check the hydraulic fluid level every 50 hours of operation. Add fluid as necessary. The level in the
hydraulic pump should be 3/4" (19mm) from the top with all cylinders collapsed.
If humidity is a problem or the mill is used outside in humid weather, drain and replace two quarts
(.95 liters) of fluid every six months. This will drain any accumulated water and help prevent pump
failure due to water ingestion. It also will prevent excessive fluid wear and allow the fluid to maintain
its hot end performance. If humidity is not a problem, drain and replace one gallon (3.8 liters) of fluid
every year to prevent fluid wear.
See Figure 3-7. If you are operating in temperatures -20° to 100° F (-29° to 38° C), use an
all-weather hydraulic fluid such as Exxon Univis J26. For alternate fluids and/or other temperature
ranges, refer to the chart below. Operating above the recommended temperature range of a fluid
could result in excessive pump wear. Operating below the recommended temperature range could
result in reduced hydraulic cylinder speed.
2. Replace the hydraulic system cartridge filter every 500 hours of operation.
3. Periodically check all hydraulic lines and fitting as needed. Replace as necessary.
