5. Snug the collar back into the clamp blocks by gently
pushing back on the collar assembly.
6. Slowly, while depressing the valve handle down,
move the shaft forward until the tool enters the
tubing. Be sure that the tool is centered with the
tubing.
7. Make the collector flange by advancing the tool
forward until the cylinder stops. Apply full pressure
for this operation. (See figure 3-A)
8. Retract the die by lifting up on the control handle.
9. Separate the collar from the tubing. Remove tooling
and return to the storage area.
MAINTENANCE
Your new bender was designed and built for years of
dependable service. The following maintenance schedule
has been formulated to produce satisfactory performance
and longevity of your machine. Reasonable care and
daily observation of wear items will supplement this
schedule and result in a prolonged service life.
HYDRAULIC OIL
Your new bender was shipped with approximately seven
gallons of hydraulic oil. The correct oil level will be shown
on the sight gauge located to the rear right of the
machine. To properly check the oil level, proceed as fol-
lows.
1. Advance the radius die until it just comes in contact
with the back shoes.
2. At this time visually check the oil by observing the oil
sight gauge. At the proper level, oil should appear
midway on the gauge.
3. If oil cannot be seen, it will necessary to add oil via
the fIller cap located on the reservoir.
If the oil level continues to drop and oil needs to be
added frequently, the machine should be
checked thoroughly for possible leaks.
Any of the following hydraulic oils may be used.
Make Brand
Chevron OC Turbine 46
Mobile DTE Medium
Texaco Rando HD 46
Conoco Turbine 46
Shell Shell Turbo 46
Citgo AW46
Pennzoil Zoil Medium or No.10
Union 76 UNAX AW46
If the above brands are not available, use any
10 medium weight mineral based hydraulic
fluid with a non-foaming additive.
NOTE:
The hydraulic oil should be changed after 1,500
hours of operation or yearly, whichever comes first.
The oil filter should also be changed at this time.
RECOMMENDED WEEKLY MAINTENANCE
Clean and re-grease guide plate, arbor and swager
clamp blocks.
Check for equal chain tension. (See page 34)
t Check all pressures. (See page 33)
t Inspect all hydraulic hoses for wear or cuts. Replace
faulty hoses.
t Check for hydraulic leaks. Repair leaks immediately.
RECOMMENDED MONTHLY MAINTENANCE
t Check depth-of-bend for accuracy.
(See pages 39 & 4O)
t Grease zirk fittings on barrel assembly.
t Clean and spray all dies with rust inhibitor.
t Tighten all hydraulic hoses as required. Do not
over-tighten.
t Check squareness of back gates and level guide
plate. Shim / adjust as required. (See page 35)
t Re-torque mounting bolts and nuts on all hydraulic
components.
t Lubricate caster assemblies.
t Remove any nicks or burrs from tooling with a small
file.
Snug arbor and ST-1 to cylinder shaft.
