7.3 SPREADING / SQUEEZING / LIFTING
Rotating the control valve actuator regulates the hydraulic flow rate and power delivered to the tool. Turning the control valve actuator to
the end stops provides maximum hydraulic flow rate and power.

WARNING
When
When operating the spreader, the tool may rotate as it meets resistance. If tool rotation places the
user, operator, or others in jeopardy, immediately release the control valve actuator. Stop and
modify the extrication procedure. The deadman safety feature returns the control valve actuator to
the center (neutral) position stopping arm movement. Seek another purchase point to proceed with
the extrication.
WARNING
When
Spreading, squeezing, pulling, and lifting operations can cause loads to become unstable. Unstable
loads can cause injury or death. To avoid load instability:
• Position the spreader tips to maintain maximum contact with the surfaces to be spread, gripped
or lifted.
•
Always stabilize the object being lifted.
