OPERATING INSTRUCTIONS
WARNING! Gasoline engines create carbon monoxide, an odorless, colorless, tasteless gas that causes headaches,
nausea, dizziness and even death if exposure is prolonged. The engine does not have to be running to use this impact
wrench. If forced to run the engine, do so in a well-ventilated area.
NOTE: The motor in this wrench spins until it reaches maximum speed, then the internal clutch automatically
engages and the nut is loosened or tightened. THIS IS NORMAL AND DOES NOT INDICATE A PROBLEM.
Prior to using this impact wrench, be sure your vehicle or wheel is secured. If wheel is still on the vehicle, make certain
the vehicle is parked on firm, level ground, that it is in “Park” and that the Emergency Brake is engaged. Use wheel
chocks on the other wheels if available or a large rock, large piece of wood – anything to prevent inadvertent movement
of the vehicle.
This tool operates on 12V DC, such as that found in a standard automobile battery. Do not attempt to use this tool with
any other voltage. Do not alter the power cord in any way. Doing so is both dangerous and voids the warranty.
As shown in Figure 1, you may connect this impact wrench directly into the 12V
receptacle (A), the cigarette lighter in your vehicle, or you may use the Battery Adapter
Cable (B) and use the vehicle battery itself.
