POWER TOOL SAFETY 12. ALWAYS WEAR EYE PROTECTION. Any power tool can throw foreign objects into the eyes and could cause permanent eye damage. ALWAYS wear Safety Goggles (not glasses) that comply with ANSI Safety standard Z87.1 Everyday eyeglasses have only impact –resistance lenses. They ARE NOT safety glasses. Safety Goggles are available at Sears. NOTE: Glasses or goggles not in compliance with ANSI Z87.1 could seriously injure you when they break.
COMPOUND MITER SAW SAFETY 18. MAKE SURE the blade is not contacting the workpiece before the switch is turned ON. SPECIFIC SAFETY INSTRUCTIONS FOR THIS COMPOUND MITER SAW 19. IMPORTANT: After completing the cut, release the power switch and wait for the blade to stop before returning the saw to the raised position. 1. USE ONLY CROSS-CUTTING SAW BLADES. When using carbide tipped blades, make sure they have a negative hook angle.
ELECTRICAL REQUIREMENTS AND SAFETY 4. FUSES may “blow” or circuit breakers may trip frequently if: a. MOTOR is overloaded – overloading can occur if you feed too rapidly or make too many start/stops in a short time. b. LINE VOLTAGE is more than 10% above or below the nameplate voltage rating. For heavy loads, the voltage at motor terminals must equal the voltage specified on the nameplate. c. IMPROPER or dull saw blades are used. 5.
ACCESSORIES AND ATTACHMENTS TOOLS NEEDED FOR ASSEMBLY RECOMMENDED ACCESSORIES Use only accessories recommended for this miter saw. Follow instructions that accompany accessories. Use of improper accessories may cause hazards. The use of any cutting tool except 10 inch saw blades that meet the requirements under recommended accessories is prohibited. Do not use accessories such as shaper cutters or dado sets.
CARTON CONTENTS UNPACKING YOUR MITER SAW To avoid injury from unexpected starting or electrical shock, do not plug the power cord into a source of power during unpacking and assembly. This cord must remain unplugged whenever you are adjusting/assembling the saw. 1. Remove the miter saw from the carton. IMPORTANT: Do not lift the miter saw by the switch handle or miter table handle. It may cause misalignment. Lift only by the built-in carry handle located at the top of the machine. 2.

GLOSSARY OF TERMS CRAFTSMAN COMPOUND MITER SAW TERMS STOP LATCH – Locks the miter saw in the lowered position for compact storage and transportation. ARBOR LOCK – Allows the user to keep the blade from rotating while tightening or loosening the arbor locking bolt during blade replacement or removal. SWITCH HANDLE – The cutting head handle contains the trigger switch and a safety lock-off slide switch. The blade is lowered into the workpiece by pushing down on the handle.
ASSEMBLY AND ADJUSTMENTS ASSEMBLY INSTRUCTIONS To avoid injury and damage to the saw, transport or store the miter saw with the cutting head locked in the down position. Never use the stop latch to hold the cutting head in a down position for cutting operations. To avoid injury, do not connect this miter saw to the power source until it is completely assembled and adjusted, and you have read and understood this Operators Manual. INSTALLING THE MITER HANDLE (FIG. A) 1.
Fig. F INSTALLING EXTENSION WINGS (FIG. E) To avoid injury or possible damage to the tool, support long work pieces by installing the extension wings to extend the work support surface. When using extension and stop block on the right side, hold down clamp must also be in right side. Using hold down clamp on the left side during this operation can cause kick-back and serious injury to the operator. INSTALLING THE STOP BLOCK (FIG. E): 1. Slide the stop block (1) onto the extension wing (2) 2.
INSTALLING THE HOLD-DOWN CLAMP (FIG. H-1) Place the Hold-down Clamp (1) in the desired mounting hole (2). 7 Fig. H 6 Fig. H-1 4 1 2 4 6 7 INSTALLING BLADE (Fig. F, G, H) 1. Install a 10” blade, making sure the rotation arrow on the blade matches the clockwise rotation arrow on the upper guard, and the blade teeth are pointing downward. 2. Place the laser guide (6) against the blade and on the arbor. Thread the arbor bolt (4) into the arbor in a counterclockwise direction. (Fig.
To Adjust Miter Angles: 1. Unlock the miter table by turning the miter handle (1) counterclockwise. 2. While holding the positive-stop locking lever (2) down, grasp the miter handle and rotate the miter table left or right to the desired angle. 3. If the desired angle is one of the nine positive stops, release the positive-stop locking lever making sure the lever snaps into position. 4.
Support the saw on a level work surface. Bolt or clamp the saw to its support. To avoid injury from an accidental start, make sure the switch is in the OFF position and the plug is not connected to the power source outlet. Place the saw in the desired location, either on a work bench or recommended leg set. The base of the saw has three mounting holes (1). - For stationary use, fasten the saw to a workbench. - For portable use, fasten the saw to a 3/4” piece of plywood.
OPERATION SAFETY INSTRUCTIONS FOR BASIC SAW OPERATIONS BEFORE USING THE MITER SAW Keep all guards in place, in working order and properly adjusted. If any part of this miter saw is missing, bent damaged or broken in any way, or any electrical parts don’t work, turn the saw off and unplug it. Replace damaged, missing, or defective parts before using the saw again.
PLAN YOUR WORK workpiece, fence and table that will let the workpiece shift after it is cut. Keep the cut off piece free to move sideways after it is cut off. Otherwise, it could get wedged against the blade and thrown violently. Only the workpiece should be on the saw’s table. Secure work. Use clamps or a vise to help hold the work when it’s practical. Use the right tool. Don’t force a tool or attachment to do a job it was not designed to do.
BODY AND HAND POSITION (FIG. P) Proper positioning of your body and hands when operating the miter saw will make cutting easier and safer. Never place hands near the cutting area. Position hands at least 7-1/4” away from the path of the blade. Hold workpiece firmly against the fence to prevent movement toward the blade. Keep hands in position until the trigger has been released and the blade has completely stopped.
MITER CUT (FIG. R) When a miter cut is required, unlock the miter table by turning the miter handle (1) counterclockwise. While holding the miter handle, press down on the positive stop locking lever (2). Rotate the miter table to the right or left with the miter handle. When the table is in the desired position as shown on the miter scale (3), release the positive stop locking lever and tighten the miter handle. The table is now locked at the desired angle. Positive stops are provided at 0°,15°,22.5°,31.
AUXILARY WOOD FENCE (FIG. W) When making multiple or repetitive cuts that result in cut-off pieces of one inch or less, it is possible for the saw blade to catch the cut-off piece and throw it out of the saw or into the blade guard and housing, possibly causing damage or injury. To minimize this an auxiliary wood fence can be mounted to your saw. Holes are provided in the saw fence to attach an auxiliary wood fence.
CUTTING A DIMENSIONAL 4X4 WITH ONE CUT (Fig. X) A dimensional 4x4-in may be cut in half with one cut by attaching an auxiliary wood fence of 3/4 inch thick. See “AUXILIARY WOOD FENCE” above. Fig. X CUTTING BASE MOLDING (FIG. Z) Base moldings and many other moldings can be cut on a compound miter saw. The setup of the saw depends on molding characteristics and applications, as shown. Perform practice cuts on scrap material to achieve best results: 1.
CUTTING CROWN MOLDING (FIG. AA, BB) Your compound miter saw is suited for the difficult task of cutting crown molding. To fit properly, crown molding must be compound-mitered with extreme accuracy. The two surfaces on a piece of crown molding that fit flat against the ceiling and wall are at angles that, when added together equal exactly 90°. Fig.
MAINTENANCE MAINTENANCE DANGER Never put lubricants on the blade while it is spinning. To avoid fire or toxic reaction, never use gasoline, naphtha acetone, lacquer thinner or similar highly volatile solvents to clean the miter saw. To avoid injury from unexpected starting or electrical shock, unplug the power cord before working on the saw. For your safety, this saw is double-insulated. To avoid electrical shock, fire or injury, use only parts identical to those identified in the parts list.
TROUBLESHOOTING GUIDE To avoid injury from accidental starting, always turn switch OFF and unplug the tool before moving, replacing the blade or making adjustments. Consult your Sears Service Center if for any reason the motor will not run. TROUBLESHOOTING GUIDE - MOTOR PROBLEM PROBLEM CAUSE SUGGESTED CORRECTIVE ACTION Brake does not stop blade within 6 seconds. 1. Motor brushes not sealed or lightly sticking. 2. Motor brake overheated from use of defective or wrong size blade or rapid ON/OFF cycling.
