Lubrication
Monthly, or more often if needed, apply a light machine
oil or grease to handle pivot points, wing hinge, and pins.
Do not apply oil to hydraulic system components.
Hydraulic Oil
Checking Level/Adding Hydraulic Oil
Before each use, check oil level. Place the bender on a flat
level surface with the ram fully retracted. Remove the oil
vent cap – oil should be even with the bottom of the fill
neck. If oil is needed, add Shell Tellus 32 Hydraulic Oil or
other equivalent high quality hydraulic oil and replace
oil vent cap. See Figure 10 for location of oil vent cap.
Changing
Once a year, or more often with heavy use or use in dusty
conditions, the hydraulic oil should be changed.
Place the pump end of the hydraulic cylinder in a con-
tainer to collect the hydraulic oil as it is drained. Directly
under the cylinder is a plug (Figure 19). Remove the plug,
filter spring and filter and allow the hydraulic fluid to
drain. Open the oil vent cap and raise the ram end of the
cylinder slightly to improve drainage. Complete drain-
age may take up to several hours. Properly dispose of
the used hydraulic oil per the Material Safety Data Sheet
(MSDS) and local requirements.
Figure 19 – Hydraulic Oil Drain Plug and Access to Filter
Clean the filter by rinsing in clean hydraulic oil. Re-install
the clean or new filter, spring and plug. Fill the bender
with new hydraulic oil following the instructions for
adding hydraulic oil. Operate the bender through sev-
eral cycles to remove air from the system and check the
hydraulic oil level.
Oil Capacity
Low Temperature Operation
If the Hydraulic Bender will be used in low tempera-
tures (Less than 23°F (-5°C)) it is recommended that the
Hydraulic oil be changed to a high quality Hydraulic oil
suitable for the temperature.
