hydraulic tank.
It is important to ensure as little air as possible in
the hydraulic system at all times. Trapped air can
cause the ram to act erratically during operation.
To purge the air from the hydraulic system, turn
the machine
ON. Fully retract the ram into the
hydraulic cylinder, then cycle the ram through its
full range of motion 4–6 times.
Air has been properly purged when the ram
moves smoothly through its full cycle while apply-
ing pressure to the workpiece.
The hydraulic fluid should be changed after the
first 3,000 hours of operations, then every 5,000
hours thereafter.
Items Needed:
Qty
ISO-46 Hydraulic Fluid ....................... 13 Gallons
Open-Ended Wrench 17mm .............................. 1
Clean Rags ........................................ As Needed
15 Gallon Drain Pan .......................................... 1
Funnel ................................................................ 1
To change hydraulic fluid:
1. Position drain pan beneath hydraulic tank
and remove fill cap from top of tank.
3. Remove drain pan and dispose of fluid
according to state and federal regulations.
4. Re-install drain plug, then insert funnel into
top of tank and pour in new hydraulic fluid
until it reaches fill mark in sight glass (see
Figure 26).

5. Replace fill cap and operate press as outlined
in
Purging Hydraulic System to ensure
proper performance.
