SAFETY GUIDELINES - DEFINITIONS It is important for you to read and understand this manual. The information it contains relates to protecting YOUR SAFETY and PREVENTING PROBLEMS. The symbols below are used to help you recognize this information. Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
Porter-Cable may cause hazards or risk of injury to persons. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in “OFF” position before plugging in power cord.
15. NEVER START THE TOOL with the workpiece against the blade. 16. KEEP HANDS out of path of saw blade. Clamp all workpieces that would require your hand to be in the “Table Hazard Zone” (within the red lines).
POWER CONNECTIONS A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3- prong grounding type plugs and matching receptacle which will accept the machine’s plug.
FUNCTIONAL DESCRIPTION FOREWORD Porter-Cable Model 3700L is a high capacity, 10" compound laser miter saw designed to cut wood and non-ferrous metals. This unit incorporates the latest technology TwinLaser™ line-of-cut indicator feature. It can crosscut 5-1/2" x 2-3/8" and 3-1/2" x 3-1/16", miter at 45° right 3-3/8" x 3-1/16", miter at 45° left 2-5/8" x 3-7/16", bevel at 45° left 5-1/2"...
UNPACKING AND CLEANING 1. Carefully remove the machine from the carton. Retain all packing materials until you have inspected and satisfactorily operated the machine. Do not operate this machine until you read and understand the entire instruction manual. 2. Place the machine on a firm, level surface with extra room for handling and proper support of the workpiece. 3.

Use a straight edge to align the fence slide support with the saw fence, and tighten the two screws. Position the fence slide (K) Fig. 8 in the valley on the top of the saw fence (J) and the fence slide support (E). Move the fence slide (K) back and forth several times to check the alignment of the fence slide support (E).
To start the machine, depress the switch trigger (A) Fig. 13. To stop the machine, release the switch trigger. This saw is equipped with an automatic electric blade brake. As soon as the switch trigger (A) Fig. 13 is released, the electric brake is activated and stops the blade in seconds.

ROTATING THE TABLE FOR MITER CUTTING This miter saw will cut any angle from 0° to 47° right and left. Turn the locking knob (A) Fig. 15 counter-clockwise, lift the miter detent trigger (B), and rotate the table. The compound miter saw is equipped with positive stops at 0°, 15°, 22.5°, 30°, and 45° left and right.
The sliding fence (A) Fig. 23 provides support for extra large workpieces used with your saw. Set it as close as possible to the saw blade. When miter cutting (blade 90° to the table and at an angle to the right or left), set the fence all the way toward the blade (Fig.
ADJUSTING 0° AND 45° BEVEL POSITIVE STOPS DISCONNECT THE MACHINE FROM THE POWER SOURCE. Adjust the saw so that both the bevel and miter pointers are set at 0°. Tighten the bevel lock handle (A) Fig. 25 and lock the cuttinghead in the down position.
HOW TO CHECK LASER ALIGNMENT Make sure the saw is set to 0 degrees, miter and bevel, and clamp a 2"x 6" board on the saw. Create a partial test cut in the workpiece (Fig. C). Turn the laser “ON/OFF” switch (Fig. B) to the “ON” position. Leave the workpiece clamped in place for the remainder of the adjustment.

(Fig. A). Use the 1/8" hex wrench to turn the left or right vertical alignment set screws. If, as the saw head goes from a raised to a lowered position, the laser line moves horizontally away from the blade, turn the vertical alignment set screw clockwise to correct.
Remove the blade from the saw and clean pitch build-up from the blade (Fig. K) Pitch build-up can block the laser and prevent it from accurately indicating the line-of-cut.
Fig. 34. This auxiliary fence is constructed of straight wood approximately 1/2" thick by 3" high by 20" long. NOTE: The auxiliary fence (A) is used ONLY with the saw blade in the 0 degree bevel position (90 degrees to the table). When bevel cutting (blade tilted), remove the auxiliary fence.
NOTE: Ensure that the top of the support 2 x 4’s (C) are level with the miter saw table. This is critical because the distance from the top of the 2 x 4’s (A) to the miter saw table varies from saw to saw. In most cases, standard 2 x 4’s (C) can used.
CUTTING CROWN MOULDING One of the many features of the saw is the ease of cutting crown moulding. The following is an example of cutting both inside and outside corners on 52°/38° wall angle crown moulding. 1. Move the table to the 31.62° right miter position and lock the table in position.

CHANGING THE BLADE Use only cross-cutting saw blades. When using carbide-tipped blades, do not use blades with deep gullets as they can deflect and contact the guard.
