Jet Tools JMS-12SCMS manual Maintenance, Replacing Carbon Brushes, Lower Blade Guard, Saw Dust

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.
