HYDRAULIC FLUID BLEEDING
PROCEDURE
1.
Fill the hydraulic tank with a recommended
hydraulic oil (refer to page 28) to a level
¹⁄₂
"
below the top of the tank.
2.
Remove the plug from the tee fitting near
the hydraulic cylinder.
3.
Install the bleeder tube (supplied with tool),
hand tight, into the tee fitting.
4.
Remove breather cap. Insert the end of the
bleeder tube (clear hose) into the tank so the
tube end is submerged in the hydraulic fluid.
5.
Connect the tool to its proper power supply.
6.
Set power switch to the “ON” position.
7.
Flip toggle switch to the “Jog” position.
8.
Depress the safety foot switch and observe
the hydraulic fluid start flowing through the
bleeder tube. The fluid should have air bubbles
in it. Continue running the fluid through the
bleeder tube for at least five minutes. While
doing this, lightly tap on all of the steel hydrau-
lic tubes to free air trapped on tubing inside
walls. Also, manually depress and release the
hydraulic cylinder ram several times to free
trapped air inside cylinder. Do this while the
fluid is flowing through the bleeder tube. Once
the fluid is flowing through the bleeder tube
without any air bubbles, continue running for
at least two to three minutes. Release foot
switch.
• Lower roll will rotate during Step 8. Avoid contact
with lower roll.
Failure to do so may result in serious personal injury.
