2-4 EM-506 (N-07/03)

This condition is corrected by adding or removing shims

under one of the rear housing feet. In Example #2 the

excessive clearance was at the right guide and slide.

Since this measurement was positive, the clearance was

at the top. 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.

After the machine is level, retighten foundation bolt nuts

securely. Recheck guide and slide alignment.

IMPORTANT: Before running the machine, tighten

the guide clamp bolts to 60 ft.-lbs. (81.4Nm) and

lubricate slide liners with light hydraulic oil. Use

tool shown in Figure 2-4 supplied by

CINCINNATI INCORPORATED.

IMPORTANT: After loosening and tightening guide

clamp bolts for ram guide and slide alignments, the

linear transducers should be checked and possibly

reset per “Ram Linear Transducer Adjustment”

instructions in SECTION 9.

Alignment may not be permanent. Recheck level in a

few weeks. Do not use any grouting around the machine.

For machines where the bed goes below floor level,

leave the bed pit empty and cover exposed pit opening

with steel plate.

HYDRAULIC RESERVOIR

The hydraulic reservoir is equipped with a drain valve.

See Figure 1-2. Before starting machine, crack this valve

open. Water may have collected in the tank during

shipment. If no water comes out, or when oil starts

coming out, close the valve securely. Repeat this check

monthly.

LUBRICATION

Proper lubrication is of extreme importance to your

machine. The following lubrication points should be

checked before start-up and at regular intervals

thereafter.

1. Hydraulic Reservoir: Before starting machine check

for proper fluid level at the oil sight gage. The ram

must be at full open height to properly check fluid

level. See Figure 1-2. Refer to

SECTION 9 for

details about proper fluid level.

2. Cylinder Clevis Pins: Lubricate while cycling ram

under load, such as obtained with a bumping die.

Lubricate once a month. Use a #2 lithium base

grease with “moly” additive (C.I. grease H-2M).

This must be done after electrical connections are

made and the machine is running.

3. Ram Guides and Slide Liners: Wipe clean and flush

with light hydraulic oil.

4. Gages: Clean and lubricate all exposed guide rails

with a light coating of spray lubricant or #10 oil. The

X and R-Axis ballscrews should also be lubricated

with a light coating of spray lubricant or #10 oil.

These ballscrews are easily accessed by removing

the protective covers. Do not use grease on the

ballscrews. See

SECTION 9, MAINTENANCE &

ADJUSTMENTS for more specific details.

ELECTRICAL CONNECTION

Suitable electrical leads must be brought to the machine

as shown on Foundation Plan drawing. These leads are

connected to the incoming side of electrical disconnect

switch in the main electrical enclosure. Be certain that

leads are the correct size and that proper voltage is fed to

the machine. CINCINNATI INCORPORATED

equipment requires that the incoming line supply at the

machine does not vary more than plus or minus 10%

from the nominal. Some installations may require

additional line conditioning other than supplied with the

machine controls. Contact CINCINNATI

INCORPORATED Service Department for further

information.

Machine must be connected to a good earth ground. A

ground lug on the electrical panel near the disconnect is
