9.0  LUBRICATION

 

NOTICE

 Use NLGI 2 grease for all grease lubrication 

procedures in Sections 9.1 through 9.4.

9.1  Lifting Wedge Lubrication (all models)

Machined surfaces and moving parts should be liberally 

coated with grease BEFORE each use. Without lubrication, 

binding and galling of lifting wedge components may occur 

during the retract stroke, resulting in possible erratic operation 

and/or excessive wear.
Use the following procedure to lubricate the lifting wedge. 

Refer to Figure 7, items 1, 3, 4, 5 and 6.
1.  Remove the grease nipple from its storage location on the 

lifting wedge handle.

2.  Screw the grease nipple into the upper grease port. Attach 

the grease gun and apply grease until grease seeps out. 

This will lubricate the mating surfaces of the lifting jaw and 

the driven wedge.

3.  Remove grease nipple from the upper grease port.
4.  Screw the grease nipple into the lower grease port. Attach 

the grease gun and apply grease until grease seeps out. 

This will lubricate the mating surfaces of the driven wedge 

and the base.

5  Remove grease nipple from the lower grease port.

9.2  Alternate Lubrication Method 

(all models - if grease gun is not available)

1.  Connect hydraulic hose and hand pump to the lifting 

wedge (Model LW-16 only).

2.  Close the pump release valve.
3.  Operate the pump lever to advance the wedge.
4.  Smear grease onto the exposed surfaces of the driven 

wedge.

5.  Open the pump release valve to retract the wedge.

9.3  Guide Pin Lubrication

To lubricate the guide pins:
1.  Remove any grit or dirt from the guide pin slots. Refer to 

Figure 7, item 2.

2.  Smear grease into the guide pin slots.

9.4  Pump Linkage Lubrication (Model LWC-16 only)

Periodically apply grease to the linkage pins so that they remain 

lubricated. Refer to Figure 7, item 7.

10.0  TROUBLESHOOTING

Refer to the troubleshooting guide (Table 1 or 2, as applicable) 

for a list of possible lifting wedge operational problems, causes 

and solutions.
For repair service, contact an Enerpac Authorized Service 

Center. Inspection and repairs should be performed only by an 

Enerpac Authorized Service Center or other qualified hydraulic 

tool service facility.
