cribbing or other suitable supports before allowing persons to
reach or work inside the danger zone.
•Be alert while operating the spreader. If items become
unstable or begin to shift or tip, stop operating the spreader
immediately. Install suitable blocking and/or cribbing as
needed to prevent items from tipping, falling or shifting.
•The spreader pressure relief valve is factory set for 10,000
PSI [700 bar]. Never attempt to disable the pressure relief valve
or change the valve setting. Allow only qualified hydraulic
technicians to check and adjust the pressure relief valve
setting.
•Do not loosen or remove any plugs on the spreader while it
is in use.
• Never perform maintenance, adjustments or repairs while
the spreader is in use.
• Do not attempt to lift vehicles, such as cars and trucks, using
the spreader. The spreader is not intended for lifting vehicles.
•No modification or alteration of this product is allowed. Do
not use the spreader for any purpose other than for which it
is intended.
• Do not loosen release valve screw more than one turn
counter-clockwise from fully closed.
• Keep the spreader away from flames and heat. Excessive
heat will soften packings and seals, resulting in fluid leaks.
For optimum performance do not expose equipment to
temperatures of 150°F [65°C] or higher. Protect the spreader
from weld spatter.

Troubleshooting Chart
Problem Possible Cause Action
1. Spreader will not lift load or lift
performance is poor.
Release valve not tightly closed. Tighten release valve.
Air trapped in spreader. Remove air as described in Section 4.1.
Low oil level. Add Enerpac HF oil as required.
Excessive load. Reduce load. Spreader is rated for a
maximum load of 3000 lbs [13.4 kN].
Internal leakage in spreader. See Authorized Enerpac Service Center.
2. Spreader will not hold load. Release valve not tightly closed. Tighten release valve.
Internal leakage in spreader. See Authorized Enerpac Service Center.
3. Spreader will not lower after
unloading.
Release valve not fully open. Check that release valve is fully open.
Spreader overfilled with oil. Drain excess oil as required.
Jaw return springs weak or damaged. Replace return springs.
Spreader hydraulic cylinder jammed. See Authorized Enerpac Service Center.
4. Handle effort decreases and
upper jaw stops moving.
Pressure relief valve opening. Reduce load. Spreader is rated for a
maximum load of 3000 lbs [13.4 kN].
4. Tilt the spreader so that the “T” port is facing down. Allow
all used oil to drain into the pan.
Note: Dispose of used oil in accordance with all applicable
laws and regulations.
5. Close the release valve by turning it fully clockwise.
6. Position the spreader on its side so that the “T” port is
facing up.
7. Place a funnel in the “T” port. Slowly pour approximately
7.3 cubic inches [120 cm3] of new Enerpac HF oil into the
funnel. Allow time for the oil to flow into the spreader.
Note: Oil reservoir is FULL when spreader is in the normal
upright position, upper jaw is fully retracted, and oil level is up
to - but not above - the “T” port. See Figure 4.
8. Using an 8mm Allen wrench, reinstall the oil fill plug in the
“T” port.
9. Close the release valve by turning it fully clockwise.
10. Remove air from spreader hydraulic system as described
in Section 4.1. After air removal procedure is completed,
check for proper operation before returning spreader to
use.
5.2 Pressure Relief Valve
The spreader's pressure relief valve is factory preset at 10,000
psi [700 bar]. It is located under the pipe plug at the top of the
valve block. See Figure 4.
The pressure relief valve setting should not require checking or
readjustment unless the spreader has been repaired, or if it is
suspected that the setting has been changed.
IMPORTANT: Allow only qualified hydraulic technicians to
check and adjust the pressure relief valve setting.
5.3 Pressure Gauge “P” Port
The “P” port is provided to allow installation of a 0-15,000 psi
[0-1000 bar] hydraulic pressure gauge. It is to be used only by
qualified hydraulic technicians for troubleshooting and analysis
purposes. See Figure 4 for “P” port location.
WARNING: Be certain that the upper jaw is fully retracted
before removing plug from “P” port. The upper jaw will
retract immediately and load will drop if “P” port plug is
removed while spreader is in use. High pressure oil leakage will
also occur.
5.4 Lubrication
Periodically lubricate all pivot pins and linkages with grease.
