20V max* LITHIUM-ION CORDLESS CIRCULAR SAW - 054-8332-4
OPERATING INSTRUCTIONS
To attach battery pack (g 1)
1. Make sure that the circular saw is turned off.
2. Align the raised rib on the battery pack with the
grooves on the bottom of the saw, and then attach
the battery pack to the saw.
NOTE: When attaching the battery pack to the tool,
make sure that the raised platform on the pack
aligns with the grooves on the bottom of the tool
main handle and that the latches snap properly into
place. Improper assembly of the battery pack can cause damage to internal components.
To detach battery pack (g 1)
1. Make sure that the circular saw is turned off.
2. Depress the battery-release button located on the front of the battery pack to release the battery pack.
3. Pull forward on the battery pack to remove it from the tool.
WARNING!
Battery tools are always in operating condition. Therefore, the circular saw should always be
turned off when not in use or when carrying the tool at your side.
Blade guard system (g 2)
The lower blade guard attached to your circular
saw is there for your protection and safety. It should
never be altered for any reason. If it becomes
damaged or begins to return slowly or sluggishly,
do not operate the saw until the lower blade guard
has been repaired or replaced. Always leave the
lower blade guard in its correct operating position
when using the saw.
DANGER!
When sawing through a workpiece, the lower blade guard does not cover the blade on the
underside of the workpiece. Since the blade is exposed on the underside of the workpiece,
ALWAYS keep hands and fingers away from the cutting area. Serious injury will result if any
part of the body comes into contact with the moving blade.

20V max* LITHIUM-ION CORDLESS CIRCULAR SAW - 054-8332-4
OPERATING INSTRUCTIONS
WARNING!
Never use the saw when the lower blade guard is not operating properly. The lower blade
guard should be checked for correct operation before each use. If you drop your saw, check
the lower blade guard and bumper for damage at all depth settings before using.
WARNING!
When using the saw, always stay alert and exercise control. Do not remove the saw from the
workpiece while the blade is moving.
Saw blades
Even the best of saw blades will not cut efciently unless it is kept clean, sharp and properly set. Using a
dull blade places a heavy load on the saw and increases the danger of kickback. Keep extra blades on hand,
so sharp blades are always available. Gum and wood pitch hardened on the blade slows the saw down. Use
gum and pitch remover, hot water or kerosene to remove them. Do not use gasoline.
WARNING!
Always remove the battery pack from the saw when assembling parts, changing blades and
making adjustments. Failure to obey this warning could cause serious personal injury.

The saw has an electric brake to quickly stop the blade rotation. The electric brake engages when the
trigger switch is released. When the brake is functioning properly, sparks may be visible through the vent
slots in the motor housing. This is normal and is the action of the brake.
WARNING!
If the electric brake repeatedly fails to quickly stop the blade rotation, the saw should be
repaired by a qualified technician.

OPERATING INSTRUCTIONS
WARNING!
Always remove the battery pack from the tool when assembling parts, changing the blade and
making adjustments. Failure to obey this warning could cause serious personal injury.
Depth-of-cut adjustments (g 8)
Always use the correct blade-depth setting. The correct blade-depth setting for all cuts should not be more
than 1/4 inch below the material being cut. Greater blade depth will increase the chance of kickback and
cause the cut to be rough. Your saw is equipped with a depth scale that enables you to accurately set the
depth-of-cut.
TO ADJUST DEPTH OF CUT
WARNING!
Always remove the battery pack
from the saw when assembling
parts, changing blades and making
adjustments. Failure to obey this
warning could cause serious personal
injury.
1. Remove the battery pack from the saw.
2. Loosen the depth-of-cut quick adjustment lever.
3. Hold the base flat against the workpiece and
raise or lower the saw until the indicator aligns
with the desired depth on the scale.
4. Securely tighten the depth-of-cut quick
adjustment lever.

1. Secure the workpiece.
2. Clamp a straight edge to the workpiece using C-clamps (not included).
NOTE: Position the C-clamps so that they will not interfere with the saw housing during the cut.
3. Press the lock-off button and depress the trigger switch to start the saw.
4. Allow the blade to reach full speed, then guide the saw into the workpiece and make the cut.
5. Saw along the straight edge to achieve a straight rip cut.
6. Release the trigger switch and allow the blade to come to a complete stop.
7. Lift the saw from the workpiece.
Always use a guide when making long or wide rip cuts with your saw. You can use either a straight edge or
an edge guide (sold separately).
NOTE: The edge guide can be used on the left or right side of the blade (g 9).
WARNING!
Always remove the battery pack from the saw when assembling parts, changing blades and
making adjustments. Failure to obey this warning could cause serious personal injury.
1. Remove the battery pack from the saw.
2. Position the edge guide (sold separately) so that the arm with the ruler side is facing up. Slide the arm of
the edge guide through the mounting slots at the front of the saw base.
3. Adjust the edge guide to the desired width of cut.
4. Tighten the edge-guide locking knob.
5. When using an edge guide, position the face of the edge guide rmly against the edge of the workpiece.
This will help make a true cut without binding the blade.The edge of the workpiece must be straight for
the cut to be straight. Use caution to prevent the blade from binding in the cut.
Operating the saw
It is important to understand the correct method for operating the saw. Refer to the instructions in this
section to learn the correct and incorrect ways of handling the saw.
WARNING!
To make sawing easier and safer, always maintain proper control of the saw. Loss of control
could cause an accident resulting in serious injury.

OPERATING INSTRUCTIONS
WARNING!
Always securely clamp and support the workpiece. Always maintain proper control of the
saw. Failure to clamp and support the workpiece and loss of control of the saw could result in
serious injury.
WARNING!
Do not bind the blade in the cut. It could cause the saw to “kickback” towards you, which
could result in serious injury.
Integrated crosscut rulers
Marked along the base across the front of the saw is a ruler for measuring repetitive cuts. It is marked
1-1/2 inches to the left of 0° and 4 inches to the right of 0° in 1/16-inch increments.
NOTE: The distance from the line of cut to the guideline is the amount you should offset the guide.
Cross cutting (g 10)
Maintain proper control of the saw. Loss of control could cause an accident resulting in serious injury.
DANGER!
When lifting the saw from the workpiece, the blade is exposed on the underside of the saw
until the lower blade guard closes. Make sure that the lower blade guard is closed before
setting the saw down.

1. Draw a guideline along the desired cutting line
before beginning the cut.
2. Support the workpiece so that the cut is always
on the operator’s side and not directly in line with
the operator’s body.
3. Support the workpiece near the cut.
4. Clamp the workpiece securely so that the
workpiece will not move during the cut (g 10).
5. Hold the saw rmly with both hands. Avoid
placing your hand on the workpiece while
making a cut (g 12).
6. Always place the weight of the saw on the
portion of the workpiece that is supported, as
shown in (g 10), and not on the “cut-off” piece,
as shown in (g 11).
7. Place the workpiece with the “good” side down.
8. Align the cutting line with the blade-guide notch
on the base (g 10).
NOTE: The saw blade aligns with the middle of the blade guide notch. Make a trial cut in scrap material
along a guideline to determine how much to offset the cutting guideline on the cutting material.
9. Rest the front edge of the base on the workpiece without touching the blade to the workpiece.
10. Start the saw and allow the blade to reach full speed.
11. Guide the saw into the workpiece, and make the cut.
12. Release the trigger switch and allow the blade to come to a complete stop.
WARNING!
If the blade comes in contact with the workpiece before it reaches full speed, it could cause
the saw to “kickback” towards you, which could result in serious injury.
WARNING!
Do not bind the blade in the cut. It could cause the saw to “kickback” towards you, which
could result in serious injury.
