IMPORTANT SAFETY INSTRUCTIONS
WARNING: When using electric tools, machines or equipment, basic safety
precautions should always be followed to reduce the risk of re, electric
shock, and personal injury.
READ ALL INSTRUCTIONS BEFORE USING THIS TOOL
1. KEEP WORK AREA CLEAN. Cluttered areas can cause injuries.
2. CONSIDER WORK AREA ENVIRONMENT. Don’t use power tools in damp,
wet, or poorly lit locations. Don’t expose tools to the rain. Keep the work area
well lit. Don’t use tools in the presence of ammable gases or liquids.
3. KEEP CHILDREN AND BYSTANDERS AWAY. All children should be kept
away from the work area. Don’t let them handle machines, tools or extension
cords.
Bystanders can be a distraction and can be injuried.
4. GROUNDED TOOLS must be plugged into an outlet that is properly
installed and grounded. Grounding provides a low-resistance path to carry
electricity to the ground away from the operator, should the tool malfunction elec-
-
trically. Do not remove the grounding prong from the plug or alter the plug in
any way. If in doubt as to whether the outlet is properly grounded according
to code, check with a qualied electrician.
5. OBSERVE PROPER PRECAUTIONS REGARDING DOUBLE INSULA-
TION. This tool is double insulated. It is equipped with a polarized plug.
One blade is wider than the other, so it will t into a polarized outlet only one
way. If you have difculty inserting the plug, try reversing it. If it still doesn’t
t , do not alter the plug; have a qualied electrician install a polarized outlet.
6. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces: pipes, radiators, ranges, and refrigerator enclosures. When your
body is grounded the risk of electric shock increases. When working wher-
ever “live” electrical wires may be encountered, try to ascertain whether
there is a danger of shock. DO NOT TOUCH ANY METAL PARTS
OF THE TOOL while using it. Hold the tool only by the plastic grip to prevent
electric shock if you contact a live wire.
7. DO NOT MISUSE THE CORD.
Never carry your tools by the cord or pull on
the cord to unplug it. Protect the cord from potential sources of damage:
heat, oil & solvents, sharp edges, or moving parts. Replace damaged cords
immediately.
8. WHEN WORKING OUTDOORS, USE AN OUTDOOR-RATED EXTENSION
CORD. An extension cord rated for outdoor use must be marked “W-A” or
“W”.
9. DO NOT EXPOSE ELECTRICAL POWER TOOLS TO MOISTURE. Rain or
wet conditions can cause water to enter the tool and lead to electric shock.
10. ENSURE THE EXTENSION CORD YOU USE IS OF SUFFICIENT GAUGE
!
FOR ITS LENGTH.
11. STORE IDLE EQUIPMENT. Store equipment in a dry area to inhibit rust.
Equipment also should be in a high location or locked up to keep out of
reach of children.
12. DON’T FORCE THE TOOL. It will do the job better and more safely at the
rate for which it was intended.
13. USE THE RIGHT TOOL. Don’t force a small tool or attachment to do the
work of a larger industrial tool. Don’t use a tool for a purpose for which it was
not intended.
14. DRESS PROPERLY. Don’t wear loose clothing or jewelry; they can be
caught in moving parts. Protective, non-electrically conductive gloves, protective
eyewear and non-skid footwear are recommended. Wear protective hair
covering to contain long hair and keep yourself from harm.

IMPORTANT SAFETY INSTRUCTIONS
15. USE EYE PROTECTION. Use a full-face mask if the work you’re doing
produces metal lings, dust or wood chips. Goggles are acceptable in other
situations. Wear a clean dust mask if the work involves creating a lot of ne
or coarse dust.
16. SECURE WORK. Use clamps or a vise to hold the work, this frees both
hands to operate the tool.
17. DON’T OVERREACH. Keep proper footing and balance at all times. Do not
reach over or across machines that are running.
18. MAINTAIN TOOLS. Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing accessories.
For safe performance. Keep handles dry, clean and free from oil and grease.
19. AVOID UNINTENTIONAL STARTING. Be sure the switch is in the OFF posi-
tion before plugging in.
20. ALWAYS CHECK AND MAKE SURE TO REMOVE ANY ADJUSTING KEYS
OR WRENCHES before turning the tool on. Left attached, these parts can y
off a moving part and result in injury.
21. DO NOT USE THE TOOL IF IT CANNOT BE SWITCHED ON OR OFF.
Have your tool repaired before using it.
22. DISCONNNECT THE PLUG FROM THE POWER SOURCE BEFORE MAKING
ANY ADJUSTMENTS.
Changing attachments or accessories can be dangerous
if the tool could accidentally start.
23. STAY ALERT. Watch what you are doing & use common sense. Don’t operate
any tool when you are tired.
24. CHECK FOR DAMAGED PARTS. Before using this tool, any part that is
damaged should be carefully checked to determine that it will operate prop-
erly and perform its intended function. Check for alignment of moving parts,
binding of moving parts, breakage of parts, mountings, and other conditions
that may affect its operation. Inspect screws and tighten any ones that are
loose. Any part that is damaged should be properly repaired or replaced by
an authorized service center unless otherwise indicated elsewhere in the in-
struction manual. Have defective switches replaced by an authorized service
center. Don’t use the tool if switch does not turn it on and off properly.
25. REPLACEMENT PARTS. When servicing, use only identical replacement
parts.
26. SERVICE AND REPAIRS should be made by qualied repair technicians at
an authorized repair center. Improperly repaired tools could cause serious
shock or injury.
1.
2. WOOD ONLY. The saw is designed for woodcutting only.
3.
DAMAGED OR WARPED SAW BLADES should not be used. They are out
of balance and could cause further damage to the saw and possible personal
injury.
4.
USE ONLY WITH GUARD IN PLACE. The guard protects the operator
from cutting debris as well as from broken pieces of the blade, should it break
in use.
5.
REPLACE THE TABLE INSERT WHEN WORN. Excessive tear-out increases
the likelihood of injury from ying debris. When setting the saw at a new angle,
check that the blade does not cut into the table insert, rear fence, or another
part of your saw.
6. ALWAYS USE THE BLADE WRENCH to tighten the saw blade onto the arbor.
7.
CONNECT YOUR MITER SAW TO A DUST COLLECTING DEVICEif pos-
sible. If not, use the dust bag that comes with the tool and empty it regularly.
USE A SAWBLADE SUITED TO THE CUTTING JOB AND MATERIAL TO BE
CUT.

8. ALWAYS USE TABLE EXTENSIONS AND CLAMPS to support the material
when sawing long work pieces.
9. THE MATERIAL SHOULD BE PLACED FIRMLY AGAINST THE FENCE AND
TABLE. The turning of the saw blade should force it down against the table
and rearward against the fence during the cut. Movement of the workpiece
during the cut may cause the blade jam and create a kickback. When this
happens, the cutting head may jump out of your hand or the workpiece may
fly loose and cause serious injury.
10. DO NOT START THE SAW WITH THE BLADE IN CONTACT WITH ANY
SURFACE. This may cause the saw to bounce or kick back violently and could
cause injury.
11. IF MAKING A CUT USING ONE HAND TO HOLD THE SAW, ensure the free
hand is clear of the cutting area.

OPERATING PROCEDURES
2. Engage the spindle lock by pressing the pin located between the
handle and the xed guard.
CAUTION: Never press the spindle lock pin while the saw is running!
3. Using protective gloves, rotate the blade by hand while pressing the pin until it
engages a slot in the arbor.
4. While holding the spindle lock pin in, and using the supplied wrench, unscrew
the arbor screw, remove the outside saw blade ange, and the saw blade.
6. Be sure that when mounting the new saw blade, the direction arrows on the
blade correspond with the arrow on the guard.
5. When replacing the blade, apply the above procedure in reverse.
CLAMPING WORKPIECE:
WARNING: For safe and accurate cuts, affix workpiece firmly into cutting position
1. Mount the hold-down clamp on one side of the fence. Insert the shaft of the hold-down
clamp into the mounting hole and tighten the hold-down clamp retainer screw
to affix the shaft of the hold-down clamp.
2. Adjust position of the hold-down clamp bracket according to the workpiece thickness
and shape. Tighten the screw to affix the bracket in place.
MOUNTING AND REMOVING THE BLADE
CAUTION! Be sure the saw is disconnected from its power source before making
1. Loosen the movable guard release screw and rotate the guard
center plate to expose the saw blade arbor screw.
