10.0 User-maintenance
Always disconnect power to
the machine before performing maintenance.
Failure to do this may result in serious personal
injury.
Change hydraulic oil and clean the suction screen
after first 3,000 hours of operation. Then change
after every 5,000 hours of operation. Follow local
regulations for disposal of used oil.
Keep table and dies and blades clean and free of
rust. Periodically apply a light coat of SAE30 oil or
equivalent to exposed metal surfaces, such as table,
fences and blades.
Keep blade area free of deposits or shavings, which
can impede cut quality and hasten blade wear.
Inspect blades and punch and dies before each use
for chips, cracks, or other defects which could cause
metal to break off during operation.
When blades become dull, they can be removed
and sharpened.
At the beginning of each workday or shift, but at a
minimum, weekly grease the rocker arm pivot and
the punch ram slide using NLGI#2 grease.
10.1 Blade Inspection
Always disconnect power to
the machine before performing maintenance.
Failure to do this may result in serious personal
injury.
Blades are sharp! Always wear
leather gloves and use caution when working
with the blades.
Failure to do this may result in serious personal
injury.

Shear blades are wearing parts and need to be
maintained or replaced over time. When worn or
chipped, shear blades must be replaced.
Observe the following procedure when maintaining
the Ironworker shear station.
Turn off power to machine by pressing the red
stop/off button and lockout upstream power at the
main electrical panel.
At the back (output side) visually inspect the blades
for defects. If any physical defects are found, the
blades must be replaced.
The blades may be disassembled from the station
and replaced when cut quality is reduced as the
blades become dull.
Maintain 0.010 clearance between fixed and
movable shear blades at all times. Replace the
blades if the gap cannot be restored to .010.
Reference the parts list for replacement blades.
10.2 Hydraulic Oil
The hydraulic oil is the primary medium for
transmitting pressure and also must lubricate the
running parts of the pump.
Use hydraulic oil #46 SHELL BRAND or an
equivalent with similar specifications.
Keep hydraulic reservoir filled between the Full and
Min marks on the reservoir.
Remove the oil fill cap to check the oil level. The
level should be between 1” (25.4mm) and 1/2”
(12.7mm) from bottom of filler neck (C).
A shortage of hydraulic oil will cause hydraulic
system breakdown to major mechanical
components due to overheating.
Every 5000 hours drain the hydraulic oil and fill with
3.0 – 3.2qts. of hydraulic oil. Used oil products must
be disposed of in a proper manner following your
local regulations.
