are fully charged. 
To install the battery packs (T) into the tool, align the 

battery packs with the rails on the side of the motor 

housing and slide them in until they are firmly seated in 

the tool and ensure that they do not disengage. Insert 

the dust cover (BG) into the corded power supply 

receptacle (BF) in between the batteries.

NOTICE:

 

Keep the dust cover in place whenever 

the corded power supply is not in use.

To remove the battery packs from the tool, press the 

battery release button (BA) and firmly pull the battery 

packs out. Insert them into the charger as described in the charger section of this manual.

Installing and Removing the Corded Power Supply into 

and from Tool (Fig. 16–18)

Before inserting the corded power supply into your tool, remove the end of the dust cover 

(BG) from the tool's corded power supply receptacle (BF). Pull the dust cover away from the 

tool’s corded power supply receptacle so that it does not interfere with insertion of the corded 

power supply. Inspect the corded power supply receptacle for debris. Debris inside the 

receptacle can prevent the corded power supply from fully seating. If debris is present, clean 

it using low pressure air. Refer to Cleaning the Corded Power Supply Receptacle.

NOTICE:

 

The corded power supply is for AC power sources only when used with 

this tool.

 Use with DC power sources could result in damage to the tool.

 

To install the corded power supply into your tool:

1. With the corded power supply unplugged, align

FIG. 16

BE

BF

 

its AC connector with the tool's corded 

power supply receptacle (BF) then snap into 

place.

2. Ensure that it is fully seated in the tool and 

does not disengage. 

3. Attach the dust cover (BG) to the dust cover 

holder (BH Fig. 17) in the corded power 

supply.

4.  Secure the cord clip (BD) into the tool's cord 

holder (BC, Fig. 18). Firmly press the clip into 

the holder.

5. With the tool turned off, plug the corded 

power supply into a standard 120V household 

electric power outlet. Do not attempt to 

use the corded power supply on any other 

voltage.

6. Use the tool according to the tool instructions, 

making sure the cord is located so that it will not be stepped on, tripped over, or otherwise 

subjected to damage or stress.

To remove the corded power supply from the tool, first unplug the corded power supply from 

the outlet, then press the release button (BE) and firmly pull the corded power supply out 

of the tool. Firmly press the end of the dust cover (BG) into the tool’s corded power supply 

receptacle (BF).

FIG. 19

C

To turn the saw on, push the lock-off button (C) to the left, 

then depress the trigger switch (B). The saw will run while 

the switch is depressed. Allow the blade to spin up to full 

operating speed before making the cut. To turn the saw off, 

release the switch. Allow the blade to stop before raising the 

saw head. There is no provision for locking the switch on. A 

hole (BI) is provided in the trigger for insertion of a padlock 

to lock the switch off.
Always be sure the blade has stopped before removing it 

from the kerf.

Body and Hand Position (Fig. 20A, 20B)

Proper positioning of your body and hands is crucial when operating the miter saw. Never 

place hands inside the cutting area between the two red lines on the base while the blade is 

turning. Clamp or hold the workpiece tightly to the table and the fence when cutting. Keep 

both hands in position until the trigger has been released and the blade has completely 

stopped. ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS SO THAT 

YOU CAN CHECK THE PATH OF THE BLADE. DO NOT CROSS HANDS, AS SHOWN IN 

FIGURE 20B.
Keep both feet firmly on the floor and maintain proper balance. As you move the miter arm 

left and right, follow it and stand slightly to the side of the saw blade. Sight through the guard 

louvers when following a pencil line.

Cutting With Your Saw

 WARNING: To reduce the risk of serious personal injury, turn tool off and remove 

the battery packs or power supply before transporting, making any adjustments, 

cleaning, repairing, or removing/installing attachments or accessories. 

An accidental 

start-up can cause injury.

If the slide feature is not used, ensure the saw head is pushed back as far as possible and 

the rail lock knob (V, Fig. 4) is tightened. This will prevent the saw from sliding along its rails 

as the workpiece is engaged.

NOTE:

 Although this saw will cut wood and many non-ferrous materials, we will limit our 

detailed discussion to the cutting of wood only. The same guidelines apply to the other 

materials. 

DO NOT CUT FERROUS (IRON AND STEEL) MAT ERIALS, MASONRY OR 

FIBER CEMENT WITH THIS SAW. 

Do not use any abrasive blades.

NOTE:

 Refer to 

Guard Actuation and Visibility

 in the 

Features and Controls

 section for 

important information about the lower guard before cutting.

QUALITY OF CUT

The smoothness of any cut depends on a number of variables. Things like material being cut, 

blade type, blade sharpness and rate of cut all contribute to the quality of the cut.
