WARNING

To reduce the risk of injury, wear

safety goggles or glasses with side

shields.

OPERATION

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.

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.

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.

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

Do not operate the Sawzall with the

handle rotation button pressed in

or with the handle not locked into

position.

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.

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.

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.

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.
