Cold Hammering
If the hammer is stored for a long period of time or at cold temperatures, the lubrication may become stiff and the tool may not hammer initially or the hammering may be weak. If this happens:
1.Insert a chisel into the tool.
2.Pull the trigger and apply the chisel against a scrap piece of con- crete.
3.Turn the tool On and Off every few seconds. After 15 seconds to 2 minutes, the tool will start hammering normally. The colder the hammer is, the longer it will take to warm up.
Operator Force
These hammers feature the Vibration Isolation System to provide the opera- tor with comfort without sacrificing power or performance. The motor housing is suspended independently from the switch handle. Insulating elements absorb vibration when hammering and drilling.
Ideal operator force compresses the handle slightly and allows the tool to work aggressively while the handle provides maximum vibration dampen- ing.
Excessive operator force compresses the handle too far and reduces the vibration dampening. Users will be able to feel the difference and should adjust the force to the handle accordingly.
WARNING
Applying greater pressure does not increase the tool's effec- tiveness. If the applied working pressure is too high, the shock absorber will be pushed together making vibration to the handle noticeably stronger.
Hammering Only
1.Insert a chisel or other "hammering only" accessory into the tool (see "Installing Bits and Chisels").
2.Position the tool on the workpiece.
3.Grasp both handles firmly (trigger handle and either the spade handle or straight handle).
4.Pull the trigger. Always hold the tool securely using two handles and maintain control.
5.Use only enough pressure to hold the tool in place, engage the ham- mering mechanism, and prevent the tip of the chisel from wandering. This tool has been designed to achieve top performance with only moderate pressure. Let the tool do the work.
NOTE: To engage the hammering mechanism, maintain pressure on the bit/chisel. When pressure is released, hammering stops.
6.When chiseling or chipping, hold the tool at an angle to the work area. For best performance, work from a corner or close the edge of the work and break off a small area at a time.
If a hammer iron gets stuck:
1.Unplug the tool.
2.Pull out bit lock and rotate it 180°.
3.Pull the tool off of the stuck accessory.
4.Remove the accessory from the workpiece.
Hammering with Rotation
1.Insert a drill or coring bit into the tool (see "Installing Bits and Chis- els").
2.Position the tool on the workpiece.
3.Grasp both handles firmly (trigger handle and straight handle).
WARNING
To reduce the risk of injury, hold or brace securely. Always be prepared for drill reaction when bit binds, when hole becomes clogged, when striking embedded materials, and during hole breakthrough.
4.Pull the trigger. Always hold the tool securely using the straight handle and trigger handle and maintain control.
5.Use only enough pressure to hold the tool in place, engage the ham- mering mechanism, and prevent the tip of the bit from wandering. This tool has been designed to achieve top performance with only moderate pressure. Let the tool do the work.
When pressure is released, hammering stops.
6.When drilling deep holes, the speed may begin to drop off. Pull the bit partially out of the hole while the tool is running to help clear dust.
NOTE: Do not use water to settle the dust since it will clog the bit flutes and tend to make the bit bind in the hole.
If a bit binds:
If the bit should bind, a built in, nonadjustable slip clutch prevents the bit from turning when the tool is held or braced securely. If this occurs
1.Turn off and unplug the tool.
2.Free the bit from the workpiece.
3.Clear debris from the hole.
4.Begin drilling again.
WARNING
Use MILWAUKEE core bits Cat. No.
Using Rotary Percussion Core Bits (Fig. 5 - 7)
Core bits are useful for drilling larger holes for conduit and pipe. MILWAUKEE
1.Clean and lubricate the threads on the adapter and core bit to make later removal easier. Screw the threaded end of the adapter into the rear of the core bit.
2.Push the guide plate onto the pointed end of the center pin. Insert the center pin and guide plate assembly into the core bit. Be sure the small end of the center pin is securely placed into the hole in the center of the core bit (Fig. 5).

3.Insert the adapter into the nose of the tool (see “Installing Bits and Chisels”. Set the action selector to the
