Maintenance

To avoid injury while performing maintenance, always unplug the power cord before working on the saw. Failure to comply may cause serious injury!

Never use gasoline or any highly volatile solvents to clean the miter saw. Failure to comply may cause serious injury!

Use only replacement parts that are identical to the parts list at the end of this manual and reassemble exactly as the original assembly to avoid electrical shock. Failure to comply may cause serious injury!

Replacing Carbon Brushes

Replace both carbon brushes when either has less than 1/4 in. length of carbon remaining, or if the spring or wire is damaged or burned.

To inspect or replace brushes:

1.Unplug the saw.

2.Remove the black plastic cap on the side of the motor

Remove the cap cautiously, because it is spring-loaded.

3.Pull out the brush and replace.

4.Reverse above steps to reassemble. Tighten the cap snugly, but do not over- tighten.

Replace the brush for the other side in the same manner described above.

Note: To reinstall the same brushes, first make sure the brushes go back in the way they came out. This will avoid a break-in period that reduces motor performance and increases wear.

Lower Blade Guard

Do not use the saw without the lower blade guard. The lower blade guard is attached to the saw for your protection. Should the lower guard become damaged, do not use the 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.

When cleaning the lower guard, unplug the saw from the power source receptacle to avoid unexpected startup.

Do not use solvents on the guard. They could make the plastic “cloudy” and brittle.

Saw Dust

Periodically, saw dust will accumulate under the work table and base. This could cause difficulty in the movement of the worktable when setting up a miter cut. Frequently blow out or vacuum up the saw dust.

If blowing saw dust, wear proper eye protection to keep debris from entering eyes.

Lubrication

All the motor bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions; therefore, no further lubrication is required.

Lubricate the following as necessary: Chop pivot: Apply light machine oil.

Central pivot of plastic guard: Use light household oil (sewing machine oil) on metal-to- metal or metal-to-plastic guard contact areas as required for smooth, quiet operation. Avoid excessive oil, to which saw dust will cling.

At the heart of the JMS-12SCMS is its robust motor, which delivers an impressive 15 amps of power. This strength allows it to handle a wide variety of materials, from hardwoods to softer composites, making it ideal for intricate cuts and heavy-duty applications. With a maximum cutting capacity of 12 inches, the JMS-12SCMS can effortlessly slice through larger workpieces with ease, providing the kind of versatility that woodworkers crave.

One of the primary features of the jet saw is its innovative sliding mechanism. This sliding arm design allows for expanded cutting capacity, so users can achieve precise crosscuts and bevels without the need for additional tools. The smooth glide feature ensures that the saw moves effortlessly along its track, significantly reducing friction and wear.

The JMS-12SCMS also boasts a dual bevel capability, allowing for bevel cuts up to 45 degrees left and right. This feature is particularly useful for complex projects that require intricate angles, giving users the flexibility to make precise adjustments without having to flip the workpiece. Additionally, the miter angle can be adjusted to a range of 60 degrees to the right and 52 degrees to the left, providing a comprehensive cutting range for any project.

For enhanced accuracy, this tool includes an easy-to-read digital display for miter and bevel angles, allowing users to set their cuts with confidence. The built-in laser guide further aids in precision, ensuring that every cut is exactly where it's needed.

Safety is always a priority, and the JMS-12SCMS incorporates several features to keep users protected. The saw’s blade guard effectively shields users from accidental contact with the blade, while the electric brake stops the blade quickly after the trigger is released, minimizing the risk of injury.

In conclusion, the Jet Tools JMS-12SCMS is an exceptional tool that combines robust power, innovative features, and a focus on safety. Its advanced technologies and user-friendly design make it a top choice for those seeking reliability and precision in their woodworking projects.
