OPERATION SAFETY INSTRUCTIONS FOR BASIC SAW OPERATION BEFORE USING THE MITER SAW ! WARNING To avoid mistakes that could cause serious, permanent injury, do not plug the tool in until the following steps are completed: ● Completely assemble and adjust the saw, following the instructions. (ASSEMBLY & ADJUSTMENTS) ● Learn the use and function of the ON/OFF trigger switch, on/off switch for laser, upper and lower blade guards, head hold-down latch, bevel lock handle, and cover plate screw.
● To avoid injury from jams, slips, or thrown pieces, use only recommended accessories. ● Check the dust bag before you work. Empty the bag if it is more than half-full. ● Plan ahead to protect your eyes, hands, face and ears. ● Know your miter saw. Read and understand this Operator’s Manual and labels affixed to this tool. Learn its application and limitations as well as the specific potential hazards peculiar to this tool.
DRESS FOR SAFETY Any power tool can throw foreign objects into the eyes. This can result in permanent eye damage. Everyday eyeglasses have only impact resistant lenses and are not safety glasses. Glasses or goggles not in compliance with ANSI Z87.1 could seriously injure you when they break. ● Do not wear loose clothing, gloves, neckties or jewelry (rings, watches). They can get caught and draw you into moving parts. ● Wear non-slip footwear. ● Tie back long hair. ● Roll long sleeves above the elbow.
● When cutting odd shaped workpieces, plan your work so it will not bind in the blade and cause possible injury. Molding, for example, must lie flat or be held by a fixture or jig that will not let it move when cut. ● Properly support round material such as dowel rods, or tubing, which have a tendency to roll when cut, causing the blade to “bite”. ! MAKING A BASIC CUT ! Body and Hand Position (Fig. BB) Never place hands near the cutting area.
● If the blade doesn’t stop within 6 seconds, unplug the saw and follow the instructions in TROUBLESHOOTING GUIDE section. NOTE: To make the ON/OFF switch childproof. Insert a padlock (not provided), or chain with padlock, through the hole (2) in the trigger switch, locking the tool’s switch, preventing children and other unqualified users from turning the machine on. Before freeing jammed material: ● Release trigger switch. ● Wait for all moving parts to stop. ● Unplug the miter saw.
NOTE: When transporting the saw, always secure the sliding fence in the collapsed position and locking it. Removing 1. Unlock the fence cam locking lever (1) by pushing it out toward the rear of the machine. 2. Align the slot (2) with the bolt (3) in the rear of the fence, and then lift up the sliding fence to remove it from the saw. Fig. DD 2 Installing 1. Align the slot (2) with the bolt (3) in the rear of the fence to place the sliding fence onto the miter saw fence. 2.
NOTE: The quick-cam miter table lock should lock the table and prevent it from moving. If adjustment is needed, see the section of “QUICK-CAM MITER TABLE LOCK ADJUSTMENT”. 1. For chop cutting operations on small workpieces, slide the cutting head assembly completely toward the rear of the unit and tighten the sliding carriage lock knob (1). 2. To cut wide boards up to 12-1/2 in., the sliding carriage lock knob (1) must be loosened to allow the cutting head to slide freely. Fig. GG 1 3 Fig.
left and right. These locations represent the most common angles for cutting operation. To make a miter cut: 1. Unlock the miter table by lifting up on the quick-cam miter locking lever (2). 2. While raising the positive stop locking lever (3) up, grasp the miter handle (4) and rotate the miter table left or right to the desired angle. 3. Release the positive stop locking lever and set the miter at the desired angle making sure the lever snaps into place.
BEVEL CUT (FIG. JJ) ! Fig. JJ 2 WARNING ● The sliding fence must be extended to the left when making bevel cuts. The sliding fences note three bevel angles where the user must adjust the fences to match the degree of the bevel cut. Failure to extend the sliding fence will not allow enough space for the blade to pass through which could result in serious injury. At extreme miter or bevel angles the saw blade may also contact the fence.
To Slide Cut Wide Boards (Fig. MM) 1. Unlock the sliding carriage lock knob (1) and allow the cutting head assembly to move freely. 2. Set both the desired bevel angle and/or the miter angle and lock into position. 3. Use a hold-down clamp to secure the workpiece. 4. Turn the laser guide on and position the workpiece on the table for prealignment of your cut. 5. Grasp the trigger switch handle (2) and pull the carriage (3) forward until the center of the saw blade is over the front of the workpiece (4). 6.
CUTTING GROOVES (FIG. OO) CUTTING BOWED MATERIAL (FIG. NN) ! ! WARNING WARNING DO NOT USE A DADO BLADE, use only the standard 10 in. diameter saw blade for this operation. 1. Mark lines identifying the width and depth of the desired cut on the workpiece and position on the table so the outside tip of the blade is positioned on the inside edge of the line. Use a clamp to secure the workpiece beside the blade. 2.
CUTTING BASE MOLDING (FIG. QQ) Base moldings and many other moldings can be cut on a compound miter saw. The setup of the saw depends on molding characteristics and application, as shown. Perform practice cuts on scrap material to achieve best results: 1. Always make sure moldings rest firmly against fence and table. Use hold-down, crown molding vice or C-clamps, whenever possible, and place tape on the area being clamped to avoid marks. 2. Reduce splintering by taping the cut area prior to making the cut.
CUTTING CROWN MOLDING (FIG. RR, SS) 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. RR F e n c e Workpiece Miter saw table Fig.
