MAINTENANCE
CHANGING THE BLADE
WARNING:
Use only cross-cutting saw blades.
WARNING:
When using carbide-tipped blades, do not use
blades with deep gullets as they can deflect and contact the guard.
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 counter-clockwise using the wrench (D). At the same time, use
the hex wrench (C) Fig. 43 to keep the arbor from turning.
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.
