MAINTENANCE
CHANGING THE BLADE
WARNING: Use only
WARNING: When using
WARNING: Use only 10 in. diameter saw blades which are rated for 5200 rpm or higher and have 5/8 in. diameter arbor holes.
WARNING: DISCONNECT MACHINE FROM POWER SOURCE!
1.Remove screw (A) Fig. 41 and rotate cover (B) to the rear (Fig. 42).
2.To remove the saw blade, insert the hex wrench (C)
Fig. 43 into the hex hole located on the rear end of the motor shaft to keep the shaft from turning.
3.Use a wrench (D) Fig. 44 to loosen the arbor screw (E) by turning it clockwise.
4.Remove the arbor screw (E) Fig. 44, the outside blade flange (B), and the saw blade from the saw arbor.
5.Attach the new saw blade making certain that the teeth of the saw blade are pointing down (Fig. 44). Place the outside blade flange (F) on the arbor, and attach the arbor screw (E) by turning it
6.Rotate the cover back to the front and replace the screw that was removed in STEP 1.
WARNING: Remove wrenches (C) Fig. 43 and (D) Fig. 44 before starting machine.
WARNING: The cover must be returned to its original position and the screw tightened before activating the saw. Failure to do so may allow the cover to contact the spinning saw blade resulting in damage to the saw and severe personal injury.
WARNING: DISCONNECT MACHINE FROM POWER SOURCE!
BRUSH INSPECTION AND REPLACEMENT
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 a replacement is necessary. To inspect the brushes:
WARNING: DISCONNECT MACHINE FROM POWER SOURCE!
1.Remove three screws (A) Fig. 45 and remove the motor cover
(B).
2.The brushes are located in the two holders (C) Fig. 46. Remove spade type terminal connector (D) and pull out brush holders (C).
3.Fig. 47 illustrates one of the brushes (E) removed from the holder (C). When the carbon on either brush (E) is worn to 3/16 in. in length or if either spring (F) or shunt wire is burned or damaged in any way, replace both brushes. If the brushes are found to be serviceable after re-moving, reinstall them in the same position.
KEEP THE MACHINE CLEAN
Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth.
NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.
WARNING: Wear ANSI Z87.1 safety glasses while using compressed air.
FAILURE TO START
Should your machine fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line.
