Change Hydraulic Fluid and Filter (Revision 1 and 2)
The Revision 1 and 2 HPUs are equipped with a 10 micron cartridge
filter (
A
) behind the plug on the manifold block.
Revision 2 HPU models include a 3 micron pressure filter (
B
) located
below the accumulator of the HPU with a filter bypass indicator. If
the indicator is activated, the filter needs to be changed otherwise
the filter should be replaced every 500 hours.
To change the 10 micron filter:
Ensure the HPU is unplugged
from the power source and remove the plug on the manifold block.
Remove the old filter and replace with a new filter. Install the plug.
Tighten plug to 50 ft-lb.
To change the 3 micron filter:
Use a wrench to remove the bowl
from the filter housing. Remove the old filter cartridge and replace
with a new filter cartridge. Install the bowl on the filter housing.
The hydraulic fluid should be replaced every year.
Fill the reservoir from a clean container. Refer to the
section of this manual for hydraulic fluid recommendations.
