ADDING HYDRAULIC OIL:
* Use only an AW32 or equivalent hydraulic oil. DO NOT use brake fluid.
1) Unplug the power cord.
2) Rotate the pump valve lever to the open position and allow all oil in the system
to flow into the reservoir.
3) Make sure the area around the vented fill plug is clean.
4) Remove the vented fill plug.
5) Using approved hydraulic oil as noted above, pour the oil through a clean
funnel with a filter screen into the reservoir.
6) Fill the reservoir until it is approximately 2" from the top of the reservoir.
7) Re-install the vented fill plug.
REMOVING AIR FROM THE SYSTEM (BLEEDING):
– Air trapped in the hydraulic system can cause inconsistent performance. Follow
the steps below to bleed the trapped air from the system.
NOTE: Make sure the vented fill plug is installed on the pump reservoir prior to
performing the bleeding process.
1) Remove the hydraulic cylinder from the bender frame.
2) Ensure the cylinder is properly connected to the hydraulic pump with a hose
rated for 10,000 p.s.i.
3) Secure the hydraulic cylinder in the vertical position with the hose coupler
facing up. The cylinder should be positioned lower than the pump if possible.
4) Rotate the pump valve lever to the closed position.
DO NOT start the pump motor without the cylinder properly attached
to the pump. DO NOT attempt to operate the pump to full pressure by
restricting the travel of the hydraulic cylinder (Dead Heading).
CAUTION
The hydraulic cylinder should not be advanced more
than 3/4 of its full stroke.
