Quik-Lok® Blade Clamp Maintenance
Periodically clean dust and debris from
the Quik-Lok® Blade Clamp with dry
compressed air.
If the collar resists twisting, twist itr back
and forth to shake debris loose.
Periodically lubricate Quik-Lok® Blade
Clamp with dry lubricant such as graph-
ite.
Removing broken blades from the Quik-
Lok® Blade Clamp
Unplug the tool before removing blades.
Broken blades can be removed by the
following methods.
Point the tool downward, twist the collar,
and shake the tool up and down (do not
turn the tool on while your fi ngers are
holding the blade clamp open). The
shank of the broken blade should drop
out of the clamp.
If shaking the tool doesn't work:
In most cases, a corner of the broken
blade will extend beyond the blade
clamp. Simply twist the collar and pull
the broken blade out of the clamp by this
corner.
If the broken stub doesn't extend far
enough to be grabbed by its corner, use
a thin blade with small teeth (such as a
metal cutting blade) to hook the blade
that is jammed in the clamp while twist-
ing the collar and pull it out.
OPERATION
WARNING
To reduce the risk of injury, wear
safety goggles or glasses with side
shields.
Adjustable Pivot Shoe
The shoe can be adjusted forward or back-
ward to six positions to take advantage of the
unused portion of the blade or for special jobs
requiring low blade clearance.
Fig. 3
1/4 Turn
1.
To adjust the shoe, pull the shoe
release lever down 1/4 turn and slide
the shoe forward or backward to the
desired position.
2.
To lock the shoe in position, push the
shoe release lever up.
3.
After adjusting the shoe, slowly pull
the trigger to be sure the blade always
extends beyond the shoe and your work
throughout the stroke.
DO NOT OPERATE SAWZALL WITHOUT
SHOE. STRIKING THE SPINDLE AGAINST
WORK MAY DAMAGE THE RECIPROCAT-
ING MECHANISM.
WARNING
To reduce the risk of injury, be sure
the blade always extends beyond
the shoe and work throughout the
stroke. Blades may shatter if they
impact the work or shoe (Fig. 4).

Impact Protection System
All models are equipped with a unique pat-
ented gearing system that provides effi cient
power transmission and extended life in the
most diffi cult cutting applications. This durable
system will absorb impacts, blade lock ups,
and motor stalls. These models can be used
for extreme cutting applications such as large
diameter pipe, thick metal, pallets, and heavy
demolition and renovation work as well as for
general purpose cutting.
WARNING
Do not operate the Sawzall with the
handle rotation button pressed in
or with the handle not locked into
position.
Rotating the Handle (Cat. No. 6523-21)
The 6523-21 Orbital Sawzall® handle can
rotate continuously in either direction, al-
lowing the user to achieve optimal cutting
positions and comfort. The handle can be
locked into one of eight (8) detent positions,
one at every 45° angle.
To rotate the handle:
1.
Unplug the tool.
2.
Press in the handle rotation button.
3.
Rotate the handle to the desired
position.
4.
Release the handle rotation button. This
will lock the handle fi rmly into position.
NOTE: Make sure the handle does not
rotate before using the tool.

WARNING
If the handle can not be locked
into position, do not operate the
Sawzall®. Return the Sawzall®
to a Milwaukee service facility
immediately for repair.
Starting, Stopping and Controlling
Speed
1.
To start the tool, grasp the handle fi rmly
and pull the trigger.
2.
To stop the tool, release the trigger. Al-
low the tool to come to a complete stop
before removing the blade from a partial
cut or laying the tool down.
Orbit Control Switch
®
The Orbital Sawzall
is equipped with
an orbit control switch. The tool may
be operated with straight reciprocating
(non orbital) or orbital action. Straight
reciprocating action should be used when
a smooth cut is needed. Orbital action is
recommended for fast, aggressive cut-
ting. The optimal orbital action should be
determined by the user for their specifi c cut-
ting requirements.

1.
For straight reciprocating action, move
the orbit control switch to the straight cut
symbol (1).
2.
For orbital action, move the orbit
control switch towards the orbital cut
symbol (2).
The amount of orbital action may be adjusted
by moving the orbital control switch to any
position between the two symbols. For larger
orbital action, move the orbit control switch
closer to the orbital cut symbol (2). For
smaller orbital action, move the orbit control
switch closer to the straight cut symbol (1).
Orbital action may be adjusted when the
tool is running.
NOTE: Orbital action will not operate if the
blade is installed upside down.
