GENERAL SAFETY RULES:
Cover of
Grounded
Outlet Box
ELECTRICAL SAFETY
Grounded tools must be plugged into an outlet properly
installed and grounded in accordance with all codes
and ordinances. Never remove the grounding prong or modify
the plug in any way. Do not use any adaptor plugs. Check with a
qualified electrician if you are in doubt as to whether the outlet
is properly grounded. If the tools should electrically malfunction or
break down, grounding provides a low resistance path to carry
electricity away from the user.
Outlet
Ground
Grounding
Prong
Avoid body contact with grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of
electric shock if your body is grounded.
Don’t expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord to carry the tools or
pull the plug from an outlet. Keep cord away from heat, oil,
sharp edges or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electric shock.
When operating a power tool outside, use an outdoor extension
cord marked “W-A” or “W.” These cords are rated for outdoor use
and reduce the risk of electric shock.
Note: When using an extension cord, be sure to use one heavy
enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage resulting in
loss of power and overheating. John Deere recommends
using a minimum 12 gauge extension cord not to exceed
100 feet. The table below is supplied only as a guide to
minimum gauge for extension cords, where the smaller the
gauge number, the heavier the cord.

WARNING
GENERAL SAFETY RULES:
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 plugging
in. Carrying tools with your finger on the switch or plugging in tools
that have the switch on invites accidents.
Remove adjusting keys or switches 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 eye protection. Dust mask,
nonskid safety shoes, hard hat, or hearing protection must be used
for appropriate conditions.
Never touch the moving parts. Never touch the blade while the
power cord is connect to the power source.
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 your application. The
correct tool will do the job better and safer at the rate for which it is
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 the plug from the power source before making any
adjustments, changing accessories, or storing the tool. 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.
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 or 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 may be suitable
for one tool, may become hazardous when used on another tool.
Never touch the moving parts. Never touch the blade while the
power cord is connected to the power source.

CAUTION
SPECIFIC SAFETY RULES:
DANGER: KEEP HANDS AND BODY AWAY FROM AND
TO THE SIDE OF THE BLADE. CONTACT WITH
BLADE WILL RESULT IN SERIOUS INJURY.
DANGER: KEEP HANDS 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.
WARNING: TO REDUCE THE RISK OF INJURY, CHECK
LOWER GUARD. IT MUST CLOSE INSTANTLY!
HOLD SAW WITH BOTH HANDS. SUPPORT AND
CLAMP WORK. WEAR EYE PROTECTION.
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 “Causes and Operator Prevention of Kickback.”)
Do not reach underneath the work. The guard can not protect you
from the blade below the work.
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 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 spring. If the
guard and the spring 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.
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 or its
own cord. 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 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 eccentrically, 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.

CAUTION
SPECIFIC SAFETY RULES:
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 material causing the blade to climb out of the kerf and jump
back toward 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 with both hands on the saw and position your body and arm to
allow you to resist KICKBACK forces. KICKBACK forces can be controlled by the
operator, if proper precautions are taken.
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 restarting a saw in the workpiece, center the saw blade in the kerf and check
that saw teeth are not engaged into the material. If 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.
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 may 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.

CAUTION
SPECIFIC SAFETY RULES:
CONFIRM THAT NO ITEMS SUCH AS AN ELECTRIC CABLE OR
CONDUIT ARE BURIED INSIDE
Be sure the saw will not cut through wire, cable or conduit that are
behind or under the area you are cutting. In such cases, metal parts
could become electrically live and present a serious shock hazard.
KEEP THE RIGHT PARTS IN THE RIGHT POSITION
Do not remove covers and screws which have been factory-mounted.
They perform important respective roles. Keep them in the right
positions.
SHOULD THE PLASTIC HOUSING OR HANDLE OF A POWER
TOOL BE CRACKED OR DEFORMED, DO NOT USE IT
Since cracked or deformed parts may lead to an operator receiving an
electric shock, do not use such a power tool. Immediately have it
repaired.
ALWAYS KEEP THE MOTOR AIR VENT FULLY OPENED
A constantly open motor air vent is necessary to allow air to come in
and out for cooling the motor. Do not allow it to become clogged up,
even if dust is blown through it.
OPERATE POWER TOOLS AT THE RATED VOLTAGE
Operate power tools at voltages specified on the nameplates.
STOP OPERATION IMMEDIATELY IF ANY ABNORMALITY IS
DETECTED
Should a power tool be detected as out of order or should other abnor-
malities be observed during operation, stop using the tool immediately.
NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER
OFF.
Don't leave tool until it comes to a complete stop.
CAREFULLY HANDLE POWER TOOLS
Should a power tool be dropped or struck against hard materials
inadvertently, it may be deformed, cracked, or damaged.
DO NOT WIPE PLASTIC PARTS WITH SOLVENT
Solvents such as gasoline, thinner, benzine, carbon tetrachloride, and
alcohol may damage and crack plastic parts. Do not wipe them with
such solvents. Wipe plastic parts with a soft cloth lightly dampened
with soapy water.
KEEP BLADES CLEAN AND SHARP
Sharp blades minimizes stalling and kickback.
ADJUSTMENTS
Before cutting be sure depth and bevel adjustments are tight.

b. AT-4424-J for aluminum up to 3/8" solid.
c. AT-4425-J for stainless steel up to 1/4" solid.
- Aggressive contact with blade into material. Let the blade do the work.
- Too much vibration due to insufficient clamping, worn or bent blade, or worn parts (see “Saw
Vibrates” below).
Machine will not turn on:
- Check overload. If it has been tripped, it will extend out. Push in after allowing saw to cool down to
re-set. Check continuity.
- Inspect power cord for damage. Check continuity. Replace if needed.
- Inspect brushes for excessive wear. Replace if needed.
- Do not exceed 30 minutes run time without cool down of saw.
- Check trigger switch for continuity. Replace if needed.
Losing Power:
- Inspect brushes and replace if needed.
- Extension cord too long. Limit cord length to 100’.
- Extension cord too thin. Use 12 AWG or larger.
Blade Guard Sticks:
- Remove guard and remove any foreign material. Wipe any excess material from guard & face
plate. If contact surface of guard or face plate is galled, use emery cloth or fine sandpaper to
smooth out surfaces. Guard must move freely. Use light grease on mating contact surfaces to aid
in movement.
- Check guard return spring for sufficient tension. Replace if spring is weak.
- Check guard for distortion. Replace if distorted or damaged.
Blade Spins on Spindle:
- Check for proper tightness and installation. Inspect Inner blade flange and outer blade flange
centering shoulder for wear or damage. If the flanges are allowed to slip too many times, they will
no longer hold the blade properly. Replace if wear is excessive.
- Check flange mating surfaces for flatness. Replace if excessive distortion exists.
- Check to ensure flat washer and lock washer are present between bolt head and outer blade
flange.
Saw Vibrates:
- Check blade for tightness.
- Inspect inner blade flange and outer blade flange centering shoulder for wear or damage. Replace
if needed.
- Check to ensure work is properly clamped. Both primary and drop piece can cause vibration.
- Check bevel lock and depth lock for tightness.
