3.10 Power Feed
1.
Adjust the power feed chain as needed. Measure the power feed chain tension with the saw head all the way
toward the front of the mill. Use the two lock nuts to tighten or loosen the power feed chain. Adjust the chain
until it measures 7 to 8 inches (17.8 to 20.3 cm) from the top of the top rail at its lowest point.
CAUTION!
Do not overtighten the feed chain. Damage to the power feed
motor may result.
See Figure 3-5.
3.11 Hydraulic System
1.
Check the hydraulic fluid level every fifty 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.
1.
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. To change fluid
types, replace one gallon of the current fluid with one gallon of the alternate fluid.
