Minster IOI, Service Manual

Page: 28 / 92

It is normal for the oil level in the reservoir to lower while
the lube system is in operation; however, the level
should never be permitted to fall below 2.00” (50 mm)
from the bottom of the reservoir — even during CON-
TINUOUS operation. Add oil, if necessary, to maintain
proper level. To prevent over filling, turn OFF electrical
power to the press and wait several hours for oil to drain
from upper parts of the press to the reservoir.
INITIAL LUBRICATION
The press (and its auxiliary equipment) must be thor-
oughly lubricated before it is cycled. In most cases,
dies are not in place when the press is received and
their installation should be delayed until the press has
been thoroughly lubricated, tested and found to be
working properly. Model 101 OBI/OBS Series presses
are shipped without oil in the lube reservoir.
CAUTION
DAMAGE TO THE PRESS DUE TO IMPROPER
LUBRICATION IS CONSIDERED WILLFUL
NEGLECT; SUCH ABUSE COULD RESULT IN
EXTENSIVE REPAIRS AND COSTLY DOWNTIME.
Before operating the press for the first time, or if it is
installed in a new location, complete the following
checks and procedures:
1. Fill the lube reservoir following the instructions
under “Filling And Maintaining Lube Reservoir Oil
Level,” page D-2.
2. Lubricate the counterbalance cylinder (if furnished).
Fill the counterbalance rod cup (located near the
top of the cylinder) with Minster Lubricant No. 1.
(See Figure 2D.)
3. Pour one-half pint (0.24 liters) into the slide ball box.
(See Figure 2D.)
4. Fill clutch/brake air line lubricator and slide adjust
motor/die-namic fixture air line lubricator (if sup-
plied) with an approved lubricant meeting the spec-
ifications of Minster Lubricant No. 3. (See Figure
2D.) (Refer to “Servicing the Pneumatic System” in
Section E for further information.) Do not over fill.
NOTE: Make certain the air line lubricators are set
for the proper drip rate.
5. Lubricate the (optional) inclining jack (OBI presses
only). Lubricate the jack gear box with one shot of an
approved lubricant meeting the specifications of
Minster Lubricant No. 2. (See Figure 3D.) Hand lubri-
cate the screw threads with an approved lubricant
meeting the specifications of Minster Lubricant No. 1.
6. If the press is equipped with a die cushion, and the
die cushion is equipped with a one-shot lubricator,
fill the lubricator with Minster Lubricant No. 1 and
pull the one-shot lubricator handle. If the die cush-
ion is not equipped with a one-shot lubricator, use a
hand oil gun to lubricate the die cushion with one
shot of Minster Lubricant No. 1 through the dot fit-
ting provided on the die cushion.
7. Lubricate other applicable points as instructed in
the “Summary Of Lubrication Areas” section on
page D-9.
