OperatiOn
This ratchet wrench is rated at 3/8" USS bolt size. Rating must be
down graded for spring U bolts, tie bolts, long cap screws, double
depth nuts, badly rusted conditions and spring fas ten ers as they
absorb much of the impact power. When possible, clamp or wedge the
bolt to prevent springback.
Soak rusted nuts in pen e trat ing oil and break rust seal before
removing with im pact wrench. If nut does not start to move in three to
five sec onds use a larger size impact wrench. Do not use impact
wrench be yond rated ca pac i ty as this will dras ti cal ly reduce tool life.
The forward/reversing button is used to change the ro ta tion of the
tool. When the button is set to the right, the tool will turn in a right
hand ro ta tion. When the button is set to the left, the tool will turn in a
left hand ro ta tion.

• Impact wrenches are not torque control devices
Fasteners with specific torque requirements must be
checked with suitable torque measuring devices after
installation with an impact wrench.
• Use only impact wrench sockets and accessories on this
tool.
• Do not lubricate tools with flammable or volatile
liquids such as kerosene, diesel or jet fuel.

NOTE: Actual torque on a fastener is di r ect l y related to joint hard-
ness, tool speed, condition of socket and the time the tool is allowed
to impact.
Use the simplest possible tool-to-socket hook up. Every connection
absorbs energy and reduces power.
