MAINTENANCE
CHANGING THE BLADE
1.MAKE CERTAIN THE TOOL IS DISCONNECTED FROM THE POWER SOURCE. USE ONLY 10″ DIAMETER
SAW BLADES RATED FOR 5500 RPM OR HIGHER WITH 5/8" ARBOR HOLES.
2.Raise saw blade to its maximum height and remove the table insert (A) Fig. 62. NOTE: Be careful not to lose two rubber washers (E).
3.Using the open end wrench (B) Fig. 62, place wrench on flats on saw arbor and remove arbor nut (C) using wrench (D) by turning nut clockwise. Remove blade flange and saw blade.
4.Assemble new blade making certain teeth of blade are pointing down at the front, assemble outside blade flange and nut (C). Tighten nut (C) with wrench (D) by turning nut counterclockwise while holding arbor steady with wrench (B).
5.Replace table insert (A) Fig. 62.
BRUSH INSPECTION
AND REPLACEMENT
CAUTION: BEFORE INSPECTING THE BRUSHES, DISCONNECT THE TOOL FROM THE POWER SOURCE.
Brush life varies. It depends on the load on the motor. Check the brushes after the first 50 hours of use for a new machine or after a new set of brushes has been installed.
After the first check, examine them after about 10 hours of use until such time that replacement is necessary.
To inspect the brushes, proceed as follows:
1.Disconnect the tool from the power source and remove the table insert and saw blade.
2.Raise the motor to its maximum height and tilt the arbor to 45 degrees. One brush holder is shown at (A) Fig. 63.
3.Fig. 64, illustrates the brush cap (A) and brush (B) removed for inspection. When the carbon on the brush
(B) is worn to 3/16″ in length or if either the spring or shunt wire is burned or damaged in any way, replace both brushes. If the brushes are found serviceable after removing, reinstall them in the same position as removed.
4.To inspect the other brush, the saw must be turned upside down and placed on a flat non-scratch surface. The other brush is located 180 degrees from brush (A) Fig. 63.
