Installation Instructions
Unpacking Instructions
Upon receiving your Impact Wrench promptly remove it from the shipping container. Always keep top
side of container up. Inspect unit for damage which may have incurred during shipping and report it to
carrier for claim.
Tool Preparations
The impact wrench is ready for use after unpacking and no special preparation is required. If the tool
is used in cold weather, preheat the hydraulic fluid by running power source at low engine speed.
Fluid temperature should be at or above 50 °F/10 °C (400-ssu / 82 centistoke) before use, when
using recommended fluids. Using too thick of fluid may result in tool damage.
Testing
Never stick foreign objects, fingers, or other extremities into
moving mechanism. Failure to follow these instructions may lead to
severe personal injury or tool damage.
Before operating the Impact Wrench, it is important to inspect the trigger linkage mechanism for
obstructions. Make sure all sockets are securely mounted. Follow all safety precautions when
inspecting tool.
•Connect the tool to the power source.
•Hold the impact by the handles resting it on the ground.
•When the trigger is pulled, the socket should rotate.
•Release the trigger and allow the socket to stop rotating.
•Press the button to reverse the rotation and check that the tool rotates in both directions.
When operating the Impact Wrench do not change the rotation
without letting the socket stop rotating completely. Be sure to
follow all safety guidelines.
Hose Requirements
It is not often necessary or advisable to use long hoses. All hoses must have an oil resistant inner surface
and an abrasion resistant outer surface. Each hose must have male pipe ends for most application.
Longer hoses can be used when necessary but can affect the operation of the tool due to resistance in
the hose.
If small diameter or long hoses are used, or if restrictive fittings are connected to the supply and return
ports, the pressure required to push the fluid through the system and back to the tank will be higher. This
will reduce tool power.
Important: Oil should always flow from the male coupler through the female coupler.
Note: The pressure increases in uncoupled hoses left in the sun. This may make them difficult to
connect. When possible after use, connect the free ends of the operating hoses together.
