To Check Calibration
Of The Shutheight Indicator:
1. Remove dies or tooling from the press.
2. Place the POWER, OFF-ON-BAR Selector Switch
in the ON position.
3. Start the main drive motor. Make certain that oil is
dripping from the gibs.
4. Place the Stroking Selector Switch in the INCH
position. Then position the slide at the bottom of the
stroke.
NOTE: Slide must be at exact Bottom Dead Center
of stroke.
WARNING
MAKE CERTAIN THAT ALL PERSONS ARE CLEAR
OF ANY PINCH POINTS ASSOCIATED WITH THE
OPERATION OF THE PRESS AND/OR ITS AUXIL-
IARY EQUIPMENT.
5. Stop the main drive motor. Place the Stroking
Selector Switch in the OFF position. Make certain
that the flywheel has stopped turning completely.
Attach a WARNING sign to the press controls to
warn other personnel that the press is currently
being serviced.
WARNING
MAKE CERTAIN THAT POWER IS DISCONNECTED
FROM THE MAIN DRIVE MOTOR AND THAT THE
FLYWHEEL HAS STOPPED TURNING BEFORE
PROCEEDING.
6. Turn ON the air supply to the press. Charge the
counterbalance cylinder (if applicable) with air pres-
sure that is greater than the amount shown for “0”
die weight. If the press is not equipped with a coun-
terbalance cylinder, place a hydraulic jack between
the slide face and the bed (or bolster). Place the
jack directly under the connection screw.
NOTE: To prevent damage to slide and bed (or bol-
ster), place flat steel plates between jack
and slide, and between jack and bed (or
bolster).
7. Energize the hydraulic jack and apply enough pres-
sure to support the slide assembly.
NOTE: Applied jack pressure should never exceed
5 percent of press rated tonnage.
8. Using the inside micrometer or other precision mea-
suring instrument, measure the exact distance
between the slide face and bed (or bolster). Take a
measurement near the center of the slide and
record it to the nearest thousandths of an inch (or
hundredths of a millimeter).
9. Check the actual reading on the shutheight indica-
tor and compare it with the measurement just taken.
If the indicator reading is incorrect, recalibrate the
unit according to the procedure listed under “To Cal-
ibrate The Shutheight Indicator.”
To Calibrate The Shutheight Indicator:
(Ref. Figure 5F)
1. Perform Steps 1 through 9 under “To Check Cali-
bration Of The Shutheight Indicator.”
2. Remove the shutheight indicator cover.
3. Loosen the two (2) indicator .250” - 20 x . 375” long
mounting set screws which secure the indicator to
the slide.
4. Remove the indicator with gear attached.
5. Rotate indicator gear by hand until the meter read-
ing matches the shutheight measurement taken.
6. Reinstall the meter and cover on slide.
CONNECTION CAP INSTALLATION
The connection cap and its associated mounting cap
screws are normally subjected to “snap-through” forces
whenever blanking operations are performed on the
press. To offset the effect of these forces, the connec-
tion caps are preloaded by tightening the cap screws to
a prescribed torque value. That preload is correctly set
at the factory.
If the connection caps are disassembled to remove the
slide for replacing bushings or for any other reason, the
cap screws must again be properly torqued when the
