Maintenance and Lubrication

Maintenance

DANGER: Never put lubricants on the blade while it is spinning.

WARNING: To reduce the risk of injury from unexpected starting or electrical shock, unplug the power cord before working on the saw.

WARNING: For your safety, this saw i s d ou bl e in su la te d . To avoid electrical shock, fire or injury, use only parts identical to those identified in the parts list. Reassemble exactly as original assembly to avoid electrical shock.

Replacing Carbon Brushes

The carbon brushes furnished will last approximately 50 hours of running time or 10,000 on/off cycles. Replace both carbon brushes when either has less than 1/4" length of carbon remaining. To inspect or replace brushes, first unplug the saw. Then remove the black plastic cap on the side of the motor (caution, this cap is spring loaded by the brush assembly). Then pull out the brush. Repeat for the other side. To reassemble reverse the procedure. The ears on the metal end of the brush assem- bly go in the same hole the carbon part fits into. Tighten the cap snugly but do not overtighten.

NOTE: To reinstall the same brushes, first make sure the brushes go back in the way they came out. Otherwise a break-in period will occur that will reduce motor performance and increase brush wear.

Lower Blade Guard

Do not use the saw without the lower 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 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 build up with a damp cloth.

CAUTION: Do not use solvents on the guard. They could make the plastic "cloudy" and brittle.

WARNING: When cleaning lower guard unplug the saw from the out- let to avoid unexpected start-up.

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

WARNING: If blowing sawdust, wear proper eye protection to keep debris from blowing into eyes.
