| Schedule |
Check the hydraulic fluid level daily. | ||
The hydraulic system controls the movement | ||
of the conveyor belts. In order for this system | ||
to function properly and operate at the correct | ||
temperature, the hydraulic fluid level in the tank | ||
should be | 2 | ⁄3 full between the fill lines on the fluid |
|
| |
sight window, which is located on the front of the | ||
tank (see Figure 30). | ||
To add hydraulic fluid, remove the breather | ||
cap shown in Figure 30. Use an ISO VG 10— | ||
Antiwear 10 Hydraulic Fluid or equivalent. | ||

Inspect and clean the breather cap and filler screen every 40 hours of regular use.
The breather cap is vented to allow the hydraulic system to breathe during operation. Below the breather cap is a plastic filler screen.
Visually inspect both the breather cap and the plastic filler screen. If there is visual contami- nation, clean both items with solvent and com- pressed air. Allow them to completely dry before installing back in the tank.
Hydraulic System Minor Service
The hydraulic system minor service consists of changing the fluid filter, cleaning the breather cap and filler screen, and inspecting the hydraulic fluid for signs of thermal breakdown, dust con- tamination, and water contamination.
Perform a “Minor Service” every 960 hours or every 6 months of regular use.
The hydraulic system on this machine cre- ates very high pressure and the hydraulic fluid gets hot. Always stop the resaw, open the conveyor speed valves, make sure the pressure gauge reads 0 PSI, and make sure the fluid cools down before removing any lines or servicing the hydraulic system.
To change the filter:
1.Read and understand the hydraulic safe- ty instructions on Page 6 before continu- ing!
2.Thoroughly clean the entire area around the filter to remove all dust. (Getting dust into the hydraulic system will contaminate it.)
3.Remove the filter by unscrewing it from the housing (Figure 31).
