1. Be sure that the lifting wedge is fully retracted. Close the
release valve (turn release valve knob in the clockwise
direction until hand tight - DO NOT use tools).
2. Be sure the air vent is not obstructed in any way as this will
result in a vacuum within the system and the wedge will
not advance.
3. Ensure the minimum access gap under the item to be
lifted measures 0.39" [10 mm] or greater. Refer to Figure 2.
4. Lubricate the lifting wedge with grease. Refer to
instructions in Section 9.0.
5. Place the lifting wedge under the center of the item to be
lifted. The lifting jaw contains a series of steps. The step to
be used must be fully inserted into the access gap so that
the heel of the step is in contact with the outer surface of
the item to be lifted. Refer to Figure 3.
6. Operate the hand pump lever to advance the lifting wedge.
7. When the item has been lifted to the desired height, or to
the maximum height on the step used, insert the Enerpac
SB-2 safety block (included separately with lifting wedge).
Refer to Figure 4.
WARNING
Load will be lowered in the next step. Before lowering, be
sure hands, feet and other body parts are not inside the
access gap area. Failure to observe this precaution could
result in serious personal injury.
8. Slowly open the release valve to lower the load until it is
fully supported by the safety block.
9. If the item to be lifted must be raised an additional amount,
insert the wedge under the load using the next highest
wedge step. Then, repeat steps 4 through 8 of this
procedure to raise the load an additional amount.
7.4 Enerpac LWB-1 Stepped Block Accessory
The LWB-1 stepped block is useful when lifting items containing
a larger access gap. It allows the item to be lifted higher and
with less penetration.
The stepped block is included with the LWC-16 lifting wedge and
available as an optional accessory for the LW-16 lifting wedge.
WARNING
Failure to observe and comply with the following
instructions could allow the load to become unstable and
shift position. Death and/or serious personal injury could
result if load falls on persons working in the area.
To ensure safe operation:
• The stepped block must protrude under the load at least
0.59" [15 mm].
• The full width of the stepped block must be used.

8.0 INSPECTION, MAINTENANCE & STORAGE
• Keep the lifting wedge clean. Remove any loose dirt or dust
from exterior surfaces.
• Periodically check the lifting wedge for cracks, wear and damage.
Replace any cracked, worn or damaged parts immediately.
• Periodically check hydraulic components for loose
connections, oil leaks and other obvious problems. Replace
any leaking, worn or damaged components immediately.
• Store the lifting wedge in a clean, dry and secure location.
Keep the stored lifting wedge and hoses (if present) away
from heat and direct sunlight.
• Model LW-16 only:
- To prevent dirt entry, install dust caps on hydraulic
couplers after disconnecting the hydraulic hose from the
lifting wedge.
- Change the pump hydraulic oil at the recommended
interval shown in the pump instruction sheet. Change the
oil immediately if contamination is suspected.
• 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.
