Use C-clamps to clamp this mounting board to a stable work surface at the worksite. Read and understand the entire contents of this manual before attempting assembly or operation. Failure to comply may cause serious injury. 6.6 Releasing slide carriage Loosen slide locking knob (A, Figure 8-1). 6.0 Setup and assembly When transporting or storing miter saw, the slide carriage should always be locked in position. 6.1 Unpacking Inspect contents for shipping damage or missing parts.
6.8.2 Adaptor The adaptor can be used to convert the 1-5/8 in. diameter port to 2-1/2 in. diameter, for connection to a hose used with a shop vacuum or other dust collection system. Use a hose clamp to secure the dust hose (not provided) to the saw port. 6.9 Power cord storage clips The slide carriage has two clips for cord storage when machine is not in use (D, Figure 6-1). 6.10 Saw blade wrench The hex wrench used for blade changing is stored in the rear handle (E, Figure 6-1).
7.0 Electrical connections To avoid electrical hazards, fire hazards, or damage to the machine, use proper circuit protection. Your saw is wired at the factory for 115V operation. Connect to a 120V, 15 Amp circuit and use a 15 amp time delay fuse or circuit breaker. If power cord is worn or cut, or damaged in any way, have it replaced immediately to avoid shock or fire. Before connecting to power source, be sure switch is in off position.
Cord length Wire gauge (AWG) 0 – 25 ft. 16 25- 50 ft. 14 Table 3 Important: Make certain the receptacle in question is properly grounded. If you are not sure, have a registered electrician check the receptacle. 8.0 Adjustments Figure 8-1: selecting miter angles Note: Your miter saw was adjusted by the manufacturer. However, during shipment slight misalignment may have occurred. Check the following settings and adjust if necessary prior to using this miter saw. 8.2.
8.4 Fence adjustment 8.5 Bevel adjustments 8.5.1 90° (zero) bevel stop adjustment The fence extensions must be extended to left or right, or removed entirely, when making bevel cuts, to prevent blade or guard obstruction. Failure to comply may cause serious injury. Failure to extend the fence will not allow enough space for the blade to pass through. This could result in serious injury.
8.6 Depth adjustment Cutting depth can be pre-set for even and repetitive shallow cuts, such as slots or dadoes. Figure 8-6 6. If blade is not 90° to miter table (i.e. square does not sit flush against both surfaces), turn right set screw (E, Figure 8-7) in or out until blade is 90° to table. 7. If needed, loosen screw (D, Figure 8-7) and adjust bevel angle indicator to align with zero on scale. Retighten screw. 1. Raise cutting head. 2. Loosen screw (F, Figure 8-8) and slide plate (G) outward.
9.4 Jammed material If a jam occurs, release trigger and wait for all moving parts to stop. Unplug saw and remove jammed items. 9.5 Cutting options 9.5.1 Chop cuts For chop cutting operations on small workpieces, slide cutting head completely toward rear of unit and tighten slide lock knob (A, Figure 8-1). Follow general cutting procedures of sect. 9.3. Figure 9-1 Use rocker switch atop handle to turn laser guide on and off (see Figure 4-1). The laser must align with blade cutting path. 9.5.
9.9 Crown molding Miter stops are provided at common angles of 0°, 15°, 22.5°, 31.6°, 45° left and right, and 60° right. Tilt cutting head to desired angle as shown on bevel scale. Refer to sect. 8.5.1. 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.
10.2 Lower Blade Guard Do not use saw without lower blade guard. The lower blade guard is attached to the saw for your protection. Should the lower guard become damaged, do not use saw until the damaged guard has been replaced. Develop a regular check to make sure the lower guard is working properly. Clean the lower guard of any dust or buildup with a damp cloth. 3. Pull out brush assembly.

12.0 Troubleshooting JMS-10X,12X Miter Saws Symptom Possible Cause Correction * Motor will not start No incoming power. Check plug connection to receptacle. If satisfactory, check electrical panel for blown fuse or tripped breaker – replace fuse or reset breaker. Correct the low voltage conditions. Low voltage. Faulty power cord or plug. Motor will not start: fuse blows or circuit breaker trips. Motor overheats. Motor stalls, or fails to reach full speed. Open circuit in motor or loose connection.
