WARNING

WEAR RESPIRAT ORY PROTECTION

Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contain chemicals known to the State of California to cause cancer, birth
defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-base paints,

• Crystalline Silica from bricks, cement and other masonry products, and

• Arsenic and Chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work.
To reduce your exposure to these chemicals, work in a well ventilated area and work
with approved safety equipment, such as those dust masks that are specially designed
to filter out microscopic particles.

DANGER

DANGER: KEEP HANDS AWAY FROM CUTTING AREA
Keep hand away from cutting area and blade. Keep your second hand on auxiliary handle or
motor housing. If both hands are holding the saw, they cannot be cut by the blade.

Keep your body positioned to either side of the saw blade, but not in line with the saw
blade. KICKBACK could cause the saw to jump backwards. (See KICKBACK)

Do not reach underneath the work. The guard can not protect you from the blade below the

work.

WARNING

WORK AREA
Keep work area clean and well lit. Cluttered benches

and dark areas invite accidents.

Do not operate power tools in explosive atmo­spheres, such as in the presence of flammable
liquids, gases, or dust. Power tools create sparks

which may ignite the dust of fumes.

Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to

lose control.

ELECTRICAL SAFETY
A battery operated tool with integral batteries or a separate battery pack must be recharged
only with the specified charger for the battery. A charger that may be suitable for one type of

battery may create a risk of fire when used with another battery.
Use battery operated tool only with specifically designed battery pack. Use of any other

batteries may create a risk of fire.

PERSONAL SAFETY
Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use tool while tired or under the influence of drugs, alcohol, or medication. A

moment of inattention while operating power tools may result in serious personal injury.

Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry, or long hair can be

caught in moving parts.
Avoid accidental starting. Be sure switch is off before plugged in. Carrying tools with your

finger on the switch or plugging in tools that have the switch on invites accidents.
Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left

attached to a rotating part of the tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. Proper footing and balance

enables better control of the tool in unexpected situations.
Use safety equipment. Always wear protective glasses. Dust mask, nonskid safety shoes,

hard hat, or ear plugs must be used for appropriate conditions.

Cordless Circular Saw Operator's Manual 5

CAUTION

TOOL USE AND CARE
Use clamps or other practical way to secure and support the workpiece to a stable
platform. Holding the work by hand or against your body is unstable and may lead to loss of

control.
Do not force tool. Use the correct tool for you application. The correct tool will do the job

better and safer at the rate for which it was designed.
Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the

switch is dangerous and must be repaired.

Disconnect battery pack from tool or place the switch in the locked or off position before
making any adjustments, changing accessories, or storing the tools. Such preventive safety

measures reduce the risk of starting the tool accidentally.
Store idle tools out of reach of children and other untrained persons. Tools are dangerous

in the hands of untrained users.

When battery pack is not in use, keep it away from other metal objects like: paper clips,
coins, keys, nails, screws, or other small metal objects that can make a connection form
one terminal to another. Shorting the battery terminals together may cause sparks, burns, or a

fire.
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with

sharp cutting edges are less likely to bind and are easier to control.

Check for misalignment of binding of moving parts breakage of parts, and any other
condition that may affect the tools operation. If damaged, have the tool serviced before
using. Many accidents are caused by poorly maintained tools.

Use only accessories that are recommended by the manufacturer for your model.

Accessories that my be suitable for one tool, may become hazardous when used on another tool.

SERVICE
Tool service must be performed only by qualified repair personnel. Service or maintenance

performed by unqualified personnel could result in a risk of injury.

When servicing a tool, use only identical replacement parts. Follow instructions in the
maintenance section of this manual. Use of unauthorized parts or failure to follow the

Maintenance Instructions my create a risk of electric shock or injury.

6 Cordless Circular Saw Operator's Manual

CAUTION

CHECK LOWER GUARD FOR PROPER CLOSING BEFORE EACH USE. DO NOT OPERATE
SAW IF LOWER GUARD DOES NOT MOVE FREELY AND CLOSE INSTANTLY. NEVER
CLAMP OR TIE THE LOWER GUARD INTO THE OPEN POSITION. If saw is accidentally

dropped, lower guard may be bent. Raise the lower guard with the Retracting Handle and make
sure it moves freely and does not touch the blade or any other part, in all angles and depths of
cut.

CHECK THE OPERATION AND CONDITION OF THE LOWER GUARD SPRINGS. IF THE
GUARD SPRINGS ARE NOT OPERATING PROPERLY, THEY MUST BE SERVICED
BEFORE USE. Lower guard may operate sluggishly due to damaged parts, gummy deposits,

or a buildup of debris.

LOWER GUARD SHOULD BE RETRACTED MANUALLY ONLY FOR SPECIAL CUTS SUCH
AS "POCKET CUTS" AND "COMPOUND CUTS". RAISE LOWER GUARD BY RETRACTING
HANDLE. AS SOON AS THE BLADE ENTERS THE MATERIAL, LOWER GUARD MUST BE
RELEASED. For all other sawing, the lower guard should operate automatically.

ALWAYS OBSERVE THAT THE LOWER GUARD IS COVERING THE BLADE BEFORE
PLACING SAW DOWN ON BENCH OR FLOOR. An unprotected, coasting blade will cause the

saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the
blade to stop after switch is released.

NEVER HOLD PIECE BEING CUT IN YOUR HANDS OR ACROSS YOUR LEG. It is important
to support the work properly to minimize body exposure, blade binding, or loss of control.

HOLD TOOL BY INSULATED GRIPPING SURFACES WHEN PERFORMING AN OPERATION
WHERE THE CUTTING TOOL MAY CONTACT HIDDEN WIRING. Contact with a "live" wire

will also make exposed metal parts of the tool "live" and shock the operator.
WHEN RIPPING ALWAYS USE A RIP FENCE OR STRAIGHT EDGE GUIDE. This improves

the accuracy of the cut and reduces the chance for blade binding.

ALWAYS USE BLADES WITH CORRECT SIZE AND SHAPE (DIAMOND VS. ROUND)
ARBOR HOLES. Blades that do not match the mounting hardware of the saw will run eccentri-

cally, causing loss of control.
NEVER USE DAMAGED OR INCORRECT BLADE WASHERS OR BOLTS. The blade washers

and bolt were specially designed for your saw, for optimum performance and safety of operation.

CAUSES AND OPERATOR PREVENTION OF KICKBACK: Kickback is a sudden reaction to a
pinched, bound, or misaligned saw blade, causing an uncontrolled saw to lift up and out of the
workpiece toward the operator. When the blade is pinched or bound tightly by the kerf closing
down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator.
If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade
can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back
toward the operator. Kickback is the result of tool misuse and/or incorrect operating procedures
or conditions and can be avoided by taking proper precautions as given below:

MAINTAIN A FIRM GRIP ON THE SAW AND POSITION YOUR BODY AND ARM IN A WAY
THAT ALLOWS YOU TO RESIST KICKBACK FORCES. KICKBACK forces can be controlled

by the operator, if proper precautions are taken.

Cordless Circular Saw Operator's Manual 7

CAUTION

WHEN BLADE IS BINDING, OR WHEN INTERRUPTING A CUT FOR ANY REASON,
RELEASE THE TRIGGER AND HOLD THE SAW MOTIONLESS IN THE MATERIAL UNTIL
THE BLADE COMES TO A COMPLETE STOP. NEVER ATTEMPT TO REMOVE THE SAW
FROM THE WORK OR PULL THE SAW BACKWARD WHILE THE BLADE IS IN MOTION OR
KICKBACK MAY OCCUR. Investigate and take corrective actions to eliminate the cause of

blade binding.

WHEN STARTING A SAW IN THE WORKPIECE, CENTER THE SAW BLADE IN THE KERF
AND CHECK THAT THE TEETH ARE NOT ENGAGED IN THE MATERIAL. If the saw blade is

binding, it may walk up or KICKBACK from the workpiece as the saw is restarted.

SUPPORT LARGE PANELS TO MINIMIZE THE RISK OF BLADE PINCHING AND KICKBACK.

Large panels tend to sag under their own weight. Supports must be placed under the panel on
both sides, near the line of cut and near the edge of the panel.

A TYPICAL ILLUSTRATION OF SUPPORT
FOR LARGE PANELS

(Fig. 1)

DO NOT USE DULL OR DAMAGED BLADE. Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade binding, and KICKBACK.

BLADE DEPTH AND BEVEL ADJUSTING LOCKING LEVERS MUST BE TIGHT AND SECURE
BEFORE MAKING CUT. If blade adjustment shifts while cutting, it will cause binding and

KICKBACK.

USE EXTRA CAUTION WHEN MAKING A "POCKET CUT" INTO EXISTING WALLS OR
OTHER BLIND AREAS. The protruding blade may cut objects that can cause KICKBACK.

Hold tools by insulated gripping surfaces when performing an operation where the cutting tool
may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.

NEVER TOUCH MOVING PARTS. Never place your hands, fingers or other body parts near the
tool's moving parts.

8 Cordless Circular Saw Operator's Manual

TO AVOID KICKBACK, SUPPORT THE
PANEL NEAR THE CUT

CAUTION

NEVER OPERATE WITHOUT ALL GUARDS IN PLACE. Never operate this tool without all

guards or safety features in place and in proper working order. If maintenance or servicing
requires the removal of a guard or safety feature, be sure to replace the guard or safety feature
before resuming operation of the tool.

USE RIGHT TOOL. Don't force small tool or attachment to do the job of a heavy-duty tool. Don't
use tool for purpose not intended- for example- don't use circular saw for cutting tree limbs or
logs.

NEVER USE A POWER TOOL FOR APPLICATIONS OTHER THAN THOSE SPECIFIED.

Never use a power tool for applications other than those specified in the Instruction Manual.

A CASE, LET THE BATTERY COOL BEFORE CHARGING.

WHEN THE PILOT LAMP FLICKERS RAPIDLY IN RED (AT 0.2–SECOND
INTERVALS), CHECK FOR AND TAKE OUT ANY FOREIGN OBJECTS IN
THE CHARGER’S BATTERY INSTALLATION HOLE. IF THERE ARE NO
FOREIGN OBJECTS, IT IS PROBABLE THAT THE BATTERY OR
CHARGER IS MALFUNCTIONING. TAKE IT TO YOUR AUTHORIZED
SERVICE CENTER.

SINCE THE BUILT-IN MICRO COMPUTER TAKES ABOUT 3 SECONDS
TO CONFIRM THAT THE BATTERY BEING CHARGED WITH UC24YFA
IS TAKEN OUT, WAIT FOR A MINIMUM OF 3 SECONDS BEFORE
REINSERTING IT TO CONTINUE CHARGING. IF THE BATTERY IS
REINSERTED WITHIN 3 SECONDS, THE BATTERY MAY NOT BE
PROPERLY CHARGED.

REGARDING ELECTRIC DISCHARGE IN CASE OF NEW BATTERIES, ETC:
As the internal chemical substance of new batteries and batteries that have not been used for

an extended period is not activated, the electric discharge might be low when using them the
first and second time. This is a temporary phenomenon, and normal time required for recharging
will be restored by recharging the batteries 2 – 3 times.

HOW TO MAKE THE BATTERIES PERFORM LONGER:

1. Recharge the batteries before they become completely exhausted. When you feel

that the power of the tool becomes weaker, stop using the tool and recharge its battery. If
you continue to use the tool and exhaust the electric current, the battery may be damaged
and its life will become shorter.

2. Avoid recharging at high temperatures. A rechargeable battery will be hot

immediately after use. If such a battery is recharged immediately after use, its internal
chemical substance will deteriorate, and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a while.

Operation

APPLICATIONS:

-Cutting various types of wood.

PRE-OPERATION:

1. Check the work area environment.

Check the work area to make sure that it is clear of debris and clutter.
Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

2. Check if saw blade is tightened.

While the saw blade is tightened securely for immediate use when it is assembled at the
factory, be sure to check it out again for caution's sake. A bolt can be tightened when it is
turned clockwise. Use the provided box wrench to check it out. For further details, refer to
the MOUNTING AND DISMOUNTING THE SAW BLADE.

3. Check if wing nut is tightened.

If the wing nut to adjust cutting depth (Fig. 7) is loose, injury can result. Make sure that it is
tightened securely.

4. Check performance of safety cover.

WARNING: MAKE ABSOLUTELY SURE THAT THE SAFETY COVER IS NOT FIXED.

The safety cover (refer to Fig. 2) serves to protect your body from coming into contact with
the saw blade. Make absolutely certain that the cover smoothly performs to cover the saw
blade. If the safety cover should not move smoothly, never use it without repairing it. In such
case, get in touch with a JOHN DEERE Authorized Service Center for necessary repair.

5. Check battery insertion.

ALSO, CHECK AND SEE IF IT CAN MOVE SMOOTHLY. IF THE SAW
BLADE IS KEPT EXPOSED, INJURY CAN RESULT.

6. Check for proper operation of the brake.

This circular saw features an electric brake that functions when the switch is released.
Before using the circular saw, ensure that the electric brake functions properly. If it does not,
bring the tool to a JOHN DEERE Authorized Service Center.

7. Prepare a wooden work bench (Fig. 6).

Since the saw blade will extend beyond the lower surface
of the lumber, place the lumber on a work bench when
cutting. If a square block is utilized as a work bench,
select level ground to ensure it is properly stabilized.
An unstable work bench will result in hazardous operation.

CAUTION: TO AVOID POSSIBLE ACCIDENT, ALWAYS ENSURE THAT THE

18 Cordless Circular Saw Operator's Manual

"ON" POSITION, THE POWER TOOL WILL START OPERATING
IMMEDIATELY, INVITING SERIOUS ACCIDENT.

NOT, IT MAY ACCIDENTALLY FALL OUT OF THE TOOL CAUSING
INJURY TO YOU OR SOMEONE AROUND YOU.

Operation

PRE-OPERATION:

ADJUSTING THE SAW PRIOR TO USE:

1. Adjusting the cutting depth (Fig. 7):

WARNING: IF THE WING-NUT IS LOOSE, INJURY CAN

RESULT. TIGHTEN IT SECURELY AFTER
ADJUSTMENT.

To adjust cutting depth, loosen the wing-nut and while
holding the base with one hand, move the main body up and
down to obtain the prescribed cutting depth. After adjusting
to the prescribed cutting depth, tighten the wing-nut securely.

2. Adjusting the angle of inclination:

WARNING: IF THE WING-NUT IS LOOSE, INJURY CAN

RESULT. TIGHTEN IT SECURELY AFTER
ADJUSTMENT.

As shown in Fig. 8 by loosening the wing-nut on the inclined
gauge, the saw blade may be inclined to a maximum angle of
45° in relation to the base. Always insure that the wing-nut is
thoroughly tightened after making the desired adjustment.

NOTE: Values of the inclined gauge provided on the base merely

serve as a rough guideline. For cutting operation at an
inclined posture, use the circular saw after adjusting the
angle between the base and the saw blade with a
protractor, etc.

3. Adjusting the guide piece:
On the circular saw, it is possible to make fine adjustment of
the fixing position of the guide piece, where the saw blade and
the pre-marked line are to be aligned. When the saw is shipped
from the factory, the linear portion of a front scale on the guide
piece is aligned with the central position of the saw blade.
(Fig. 9) Loosen the fixed screw on the guide piece, should the
fixing position be wrong, and make necessary adjustment of
the position. (Fig. 10)

(Fig. 7)

(Fig. 8)

(Fig. 9)

NOTE: For cutting operation at the inclination of 45 degrees,

4. Regulating the guide (Fig. 11):

Cordless Circular Saw Operator's Manual 19

make adjustment so that the notch on the guide piece and
the pre-marked line become aligned.

The cutting position can be regulated by moving the guide to
the left or right after loosening its wing-bolt. The guide may be
mounted on either the right or left side of the tool.

Operation

OPERATION:

WARNING: NEVER TOUCH THE MOVING PARTS.

NEVER OPERATE THE CIRCULAR SAW WITH THE SAW BLADE
TURNED UPWARD OR TO THE SIDE.

DO NOT FIX AND SECURE THE SWITCH LOCK. BESIDES, KEEP YOUR
FINGER OFF THE SWITCH TRIGGER WHEN THE CIRCULAR SAW IS
BEING CARRIED AROUND. OTHERWISE, THE MAIN BODY SWITCH CAN
BE INADVERTENTLY TURNED ON, RESULTING IN UNEXPECTED
ACCIDENTS.

KEEP THE LIGHT ON DURING CUTTING OPERATION ONLY. IF IT IS LIT
ON IN OTHER CASES, THE MAIN BODY SWITCH CAN BE
INADVERTENTLY TURNED ON, RESULTING IN UNEXPECTED
ACCIDENTS.

CAUTION: DON’T REMOVE CIRCULAR SAW FROM WORKPIECE DURING A CUT

NOTE: Take care not to lock the motor. If the motor is locked, immediately turn the power off. If

the motor is locked for a while, the motor or battery may be burnt.

1. Operation of switch (trigger and light switch) (Fig. 12):
a. For safe operation of the machine, a “switch lock”

is provided on the side of a handle.
If the “switch lock” is pressed in the direction
of the arrow mark, the main switch can be
turned ON. The “switch lock” is used as the
“light switch”. If the “switch lock” is engaged,
the light is turned ON.

b. After the switch is turned ON, even when you

release your hand from the switch lock, the body
continues running and the light continues being turned
ON as long as you keep on pulling the switch trigger.

c. If you release the switch trigger, you can turn OFF the

switch and the “switch lock” returns to the original
position automatically and the light turns OFF.

2. Working performance per single charge (Reference data):
Cutting capability differs according to the condition of lumber, type of saw blade, ambient
temperature, battery characteristics, etc.

To improve working efficiency per single charge,

• Minimize operation (no-load operation) other than cutting;

• Avoid any unreasonably forced pressure to the motor during cutting operation by twisting
or pressing the circular saw forcibly;

• Avoid any use of dull saw blade.

WHILE THE SAW BLADE IS MOVING.
PULL OUT THE BATTERY AFTER COMPLETING OPERATION.

3. Cutting procedures:

CAUTION: RECHECK THAT THE SAW BLADE IS

SECURELY CLAMPED.
CONFIRM THAT THE WING-NUT FOR ADJUSTING

THE SLOT DEPTH, THE WING-BOLT FOR
ADJUSTING THE ANGLE OF INCLINATION.

a. Place the base on the material, then align the premarked

line and the saw blade with the guide piece front scale
section at the front of the base. (Fig. 13)

b. When the base is not inclined, use the large notch as the

guide piece. (Fig. 13, Fig. 14) If the base is inclined (45
degrees), use the small notch as the guide piece.
(Fig. 13, Fig. 15)

NOTE: When using the saw at the inclination of 45 degrees, use

Cordless Circular Saw Operator's Manual 21

both the marks of [45 degrees] on the bevel plate and
[45] on the inclined gauge of the base. (Fig. 16)

What’s more, if it is absolutely essential to use the saw
at a precise angle, make adjustment using a protractor,
etc.

c. Ensure that the switch is turned to the ON position

before the saw blade comes in contact with the lumber.
The switch is turned ON when the trigger is squeezed;
and OFF when the trigger is released. Moving the saw
straight at a constant speed will produce optimum
cutting.

CAUTION: BEFORE STARTING TO SAW, ENSURE THAT

THE SAW BLADE HAS REACHED FULL SPEED
REVOLUTION.

SHOULD THE SAW BLADE BE STOPPED OR MADE
AN ABNORMAL NOISE DURING OPERATION, TURN
OFF THE SWITCH IMMEDIATELY.

WHEN FINISHED WITH A JOB, PULL OUT THE
BATTERY FROM THE MAIN BODY.

TWISTING AND FORCIBLY PRESSING THE SAW
DURING CUTTING CAN RESULT IN UNREASONABLE
PRESSURE ON THE MOTOR, SO TRY TO GO
STRAIGHT SMOOTHLY.

IN THE SITUATION WHERE THE CIRCULAR SAW IS
CONTINUOUSLY OPERATED WHILE REPLACING
THE BATTERY WITH STOCKED SPARE
BATTERIES ONE AFTER ANOTHER, THE MOTOR
TENDS TO OVERHEAT. THEREFORE, WHENEVER
THE HOUSING BECOMES HOT, GIVE THE SAW A
BREAK FOR A WHILE.

AVOID CUTTING OPERATION IN A STATE WHERE
THE BASE BOTTOM IS AFLOAT FROM THE MATE
RAIL BEING CUT. OTHERWISE, THE MOTOR CAN
GET LOCKED.

MOUNTING AND DISMOUNTING THE SAW BLADE

CAUTION: TO AVOID SERIOUS ACCIDENT, ENSURE THE

SWITCH IS IN THE OFF POSITION, AND PULL OUT
THE BATTERY.

1. Dismounting the saw blade:
a. Set the cutting volume at maximum, and place the

Circular Saw as shown in Fig. 17.

b. Depress the lock lever, lock the spindle, and remove the

hexagonal-head bolt and washer (B1) with the box
wrench.

c. While holding the safety cover lever to keep the safety

cover fully retracted into the saw cover, remove the saw
blade. (Fig. 18)

2. Mounting the Saw Blade (Fig. 19):

WARNING: IF THE BOLT IS WORKED USING OTHER

TOOLS THAN THE PROVIDED BOX WRENCH,
EXCESSIVE TIGHTENING AND INSUFFICIENT
TIGHTENING MAY TAKE PLACE, RESULTING IN
INJURY.

Take steps which are the reverse of detaching
procedures.

NOTE: Thoroughly remove any sawdust which has accumulated

on the spindle, bolt and washers.
To assure proper rotation direction of the saw blade, the

arrow direction on the saw blade must coincide with the
arrow direction on the saw cover.

Using the fingers, tighten the hexagonal-head bolt
retaining the saw blade as much as possible. Then
depress the lock lever, lock the spindle, and thoroughly
tighten the hexagonal-head bolt.
