Cincinnati 175 CB - Initial Lubrication

After the machine is level, retighten foundation bolt nuts
securely. Recheck guide and slide alignment.. Do not
remove shims. Alignment may not be permanent. Recheck
level in a few weeks. Do not use any grouting around the
machine. Leave the bed pit empty and cover with steel
plate (175CB x 12, 230CB x 12, 350CB x 10, 12).
This condition is corrected by adding or removing shims
under one of the rear housing feet. In the example, the
excessive clearance was at the right guide and slide. To
bring the alignment into tolerance, shims could be added
under the right rear housing foot or removed from the left
rear housing foot. The alignment must be corrected even
if it causes the bed to be out-of-leveL

Let the machine down and recheck level. Repeat as often
as necessary.
Level the machine lengthwise with the level placed parallel
to the length of the bed and in the center. Raise the
housings with leveling screw as shown in Figure 3. Place
the required flat steel shims under the low housing ~ both
at the front and at the back. .'
Level machine front-to-back with the level crosswise on
the bed, first at the right end of the bed near the housing
and then at the left end. Use jack screw to insert or
remove flat steel shims under rear of both housings as
required. Recheck and repeat until level.

Before running the machine. tighten the
guide clamp bolts to 100 ft.-Ibs.

Do not run the machine until the phenolic spacers
are removed from each ram guide, and the ram
liners have been
installed and properly lubricated.
INITIAL LUBRICATION
Before starting your hydraulic press brake, the following
Iu brication steps should be taken:
Check the ram guide and slide alignment to make sure there
is no twist in the machine. This is done by loosening the
ram clamp bolts until the ram hangs free of the guides.
Measure with a feeler gage the clearance between the ram
slide liner and the ram guide at the top and bottom. See
Figure 4.
Clearance at the top of the right slide· minus clearance at
the bottom of the right slide, must be within .004 of
clearance at the top of the left slide minus clearance at the
bottom of the left slide.
1. Check hydraulic reservoir for proper fluid level (a
sight gage is located on the rear of the tank).
2. The hydraulic reservoir is supplied with a valve.
Before starting the pump, crack this open to drain
any water that . may have collected in the tank during
shipment. If no water comes out, or when oil starts
to come out, close this valve securely. Repeat this
check monthly.
3. Remove the filler-breather neoprene shipping seal from
under the cap.

Clean exposed portions of the leveling tape.
Since the difference of .030 is greater than .004, there is a
twist in the machine.
