ASSEMBLY
OPERATION
WARNING Recharge only with the char- ger specified for the battery. For specific charg- ing instructions, read the operator’s manual supplied with your charger and battery.
WARNING Always remove battery pack before changing or removing acces- sories. Only use accessories specifically recommended for this tool. Others may be hazardous.
Inserting/Removing the Battery
To remove the battery, push in the release buttons and pull the battery pack away from the tool.
To insert the battery, slide the pack into the body of the tool. Make sure it latches securely into place.
WARNING Use only sockets and other accessories specifically designed for use on impact wrenches and drivers. Other sockets and accessories might shatter or break caus- ing injury.
Attaching and Removing Accessories
These tools are intended only for use with acces- sories designed for impact wrenches and drivers. Other sockets could shatter or break, causing injury. 1. Use only the appropriate size Square Drive
Sockets.
2. To attach a socket, align the accessory with the driveshankandpushitfirmlyovertheretainingring.
3. To remove the accessory, pull the accessory off the drive shank.
WARNING Always remove battery pack before changing or removing accesso- ries. Only use accessories specifically recom- mended for this tool. Others may be hazardous.
WARNING To reduce the risk of in- jury, keep hands away from all moving parts. Always wear safety goggles or glasses with side shields.
Using Control Switch
The control switch may be set to three positions: for- ward, reverse and lock. Due to a lockout mechanism, the control switch can only be adjusted when the trig- ger is not pressed. Always allow the motor to come to a complete stop before using the control switch. 1. For forward (clockwise) rotation, push the con-
trol switch from the right side of the tool. Check the direction of rotation before use.
2. For reverse (counterclockwise) rotation, push the control switch from the left side of the tool. Check the direction of rotation before use.
3. To lock the trigger, push the control switch to the center position. The trigger will not work when the control switch is in the locked position.
Always remove the battery pack before perform- ing maintenance, changing accessories, storing the tool and any time the tool is not in use.
Starting, Stopping and Controlling Speed These tools may be operated at any speed from 0 to full speed.
1. To start the tool, pull the trigger.
2. To vary the driving speed, increase or decrease pressure on the trigger. The further the trigger is pulled, the greater the speed.
3. To stop the tool, release the trigger.
Impacting Techniques
The longer a bolt, screw, or nut is impacted, the tighter it will become. To help prevent damaging the fasteners or workpieces, avoid excessive impact- ing. Be particularly careful when impacting smaller fasteners because they require less impacting to reach optimum torque.
Practice with various fasteners, noting the length of time required to reach the desired torque. Check the tightness with a
The torque required to loosen a fastener averages 75% to 80% of the tightening torque, depending on the condition of the contacting surfaces.
On light gasket jobs, run each fastener down to a relatively light torque and use a hand torque wrench for final tightening.
