MAINTENANCE [,A DANGER i To avoid injury, never put lubricants on the blade while it is spinning. [_, WARNING I To avoid fire or toxic reaction, never use gasoline, naphtha acetone, lacquer thinner or similar highly volatile solvents to clean the miter saw. _,A WARNING I To avoid injury from unexpected starting or electrical shock, unplug the power cord before working on the saw. [_, WARNING] For your safety, this saw is double-insulated. To avoid electrical shock, fire or injury, use only parts identical to those identified in the parts list. Reassemble exactly as the original assembly to avoid electrical shock. 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. CAUTION: Do not use solvents on the guard. They could make the plastic "cloudy" and brittle. I_. WARNING] When cleaning the lower guard, unplug the saw from the power source receptacle to avoid unexpected startup. SAWDUST Periodically, sawdust 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 sawdust. I_ WARNING] If blowing sawdust, wear proper eye protection to keep debris from blowing into eyes. REPLACING CARBON BRUSHES (FIG. FF) 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, first unplug the saw. Then remove the black plastic cap (1) on the side of the motor (2). Remove the cap cautiously, because it is springloaded. Then pull out the brush and replace. Replace for the other side. To reassemble reverse the procedure. The ears on the metal end of the assembly 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. This will avoid a break-in period that reduces motor performance and increases wear. Fig. FF LUBRiCATiON (FIG. GG, HH) 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 bearing lubrication is required. Lubricate the following as necessary: Chop pivot: Apply light machine oil to points indicated in illustration. Fig. GG Chop pivot Central pivot of plastic guard: Use light household oil (sewing machine oil ) on metal-to-metal or metal-toplastic guard contact areas as required for smooth, quiet operation. Avoid excessive oil, to which sawdust will cling. Fig. HH Central pivot plastic guard 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, 23
