BLADE SELECTION

In order to obtain the best performance from

the saw, it is important to select the correct

blade for the particular application and type

of material to be cut.

Blades with fewer teeth, such as those with

10 teeth per inch (TPI), are typically used

for cutting wood, while blades with more

teeth are better for cutting metal or plastic.

We recommend 14 TPI for plastics and soft

metals and 18 TPI for hard metals.

INSTALLING A SAW

BLADE (FIG. 4)

1. Remove the battery pack from the saw.

2. Rotate the blade clamp counterclockwise

and hold it open.

3. nsert saw blade until it is fully seated, and

release the blade clamp to secure the blade

in position.

REMOVING THE SAW

BLADE (FIG. 4)

1. Remove the battery pack from the saw.

2. Rotate the blade clamp counterclockwise

and hold it open.

3. Remove the saw blade from the blade

clamp.

WARNING:

The saw blade may be

hot after use. Allow the blade to cool or

wear gloves when removing a blade.

GENERAL CUTTING

(FIG. 5A AND 5B)

WARNING:

Before attaching the

battery pack on the tool, always check

to determine that the switch performs

properly and returns to the “OFF” position

when released.

WARNING:

Hold the tool only by

the plastic handle and the insulated grip

area to help prevent electrical shock.

When sawing into walls or oors you may

encounter electrical wiring. Sawing into a

“live” wire will cause electric shock.

1. Make sure that the workpiece is firmly clamped.

2. Use the appropriate type and size of blade

for the workpiece material and size.

3. Check for clearance behind the workpiece

so that the blade will not impact another

surface.

4. Mark the line of cut clearly. If cutting

metal, apply cutting oil on the line.

5. Hold the saw firmly with one hand on the

insulated gripping surface. Do not use two

hands with this saw (Figs 5a and 5b).

6. Depress the lock-off button and trigger

switch to start the saw and bring it to the

maximum desired cutting speed before

applying the blade to the workpiece.

7. With the shoe firmly on the workpiece,

apply the blade to the workpiece and begin

the cut.

8. Do not force the tool. Place the shoe

firmly on the workpiece while cutting. Use

only enough steady pressure on the blade

to keep the saw cutting.

9. Reduce pressure as the blade comes to

the end of the cut.

10. Allow the saw to come to a complete

stop before removing the blade from the

workpiece.

11. If sawing fiberglass, plaster, wallboard,

or spackling compound, clean the saw

motor vents frequently with a vacuum or

compressed air. These materials are highly

abrasive and may accelerate the wear on

motor bearings and brushes.
