Milwaukee 2668-21CT Benutzerhandbuch

This impact driver is intended for use with drill and 

driver bits with a 1/4" hex shank and ball detent 

recess. 

1. To attach an accessory, pull the ring out and 

insert the shank. Release the ring. It may be 

necessary to pull the bit out slightly to engage 

the holding mechanism.

2. To remove the accessory, pull out the ring and 

remove the accessory. Release the ring.

1. Use only the appropriate size Square Drive 

Sockets.

2. To attach a socket, align the accessory with the 

anvil and push it fi rmly over the retaining ring.

3. To remove the accessory, pull the accessory 

off the anvil.

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.

To rotate the drive head for a more comfortable grip:

1. Loosen the drive head screw. 

2. Pull the drive head away from the tool and rotate 

to one of the detent positions. 

3. Press the drive head onto the tool and tighten 

the drive head screw securely.

1. To start the tool, grasp the tool by the insulated 

gripping surface and pull the paddle switch. Keep 

hands clear of the drive head.

  NOTE: An LED is turned on when the trigger is 

pulled.

2. To vary the driving speed, increase or decrease 

pressure on the paddle switch. The further the 

paddle switch is pulled, the greater the speed. 

3. To stop the tool, release the paddle switch.

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 hand-torque wrench. If the fasten-

ers are too tight, reduce the impacting time. If they 

are not tight enough, increase the impacting time.

Oil, dirt, rust or other matter on the threads or 

under the head of the fastener affects the degree 

of tightness.

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 fi nal tightening.

The control switch may be set to three positions: 

forward, reverse and lock. Always allow the motor 

to come to a complete stop before using the control 

switch to avoid damage to the tool.

For forward (clockwise) rotation, push in the control 

switch from the right side of the tool ►. Check the 

direction of rotation before use.

For reverse (counterclockwise) rotation, push in 

the control switch from the left side of the tool ◄. 

Check direction of rotation before use. 

To lock the trigger, push the control switch to the 

center position. The trigger will not work while the 

control switch is in the center locked position. Always 

lock the trigger or remove the battery pack before 

performing maintenance, changing accessories, 

storing the tool and any time the tool is not in use.

Allow the tool to come to a complete stop before 

changing speeds.

1. For  Low speed, push the speed selector to 

display “1”.

2. For  High speed, push the speed selector to 

display “2”.
