THE GIBS (DOVETAIL SLIDES)
The gibs require adjustment if too loose. To adjust, loosen the lock nuts and
adjust the adjustor screws evenly while moving the handle up and down.
Adjust so that there is no free play, and no binding anywhere in its range of
travel. Then retighten the lock nuts. Periodically check, lubricate, and adjust as
needed.
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and must be replaced when they reach their wear limit.
Caution: Always replace the brushes as a pair.
To replace:
1. Remove the 4 screws and remove the motor tail cover.
2. Using pliers rotate the brush spring out of the way and slide the old
carbon brush out of the brush holder.
3. Unscrew the screw to remove the brush lead. The old carbon brush may
now be lifted away.
4. Install a new brush. Installation is the reverse of removal.
5. Replace the motor tail cover.
AUTO STOP CARBON BRUSH
Due to the auto stop carbon brush design, if the machine comes to a stop
without any reason, the brushes have to be checked. The auto stop feature
stops the machine before the carbon brushes are finished and protects the
motor.
MAGNET TROUBLESHOOTING
Full magnet performance is absolutely essential for magnetic drill operation.
If the magnet works, but does not hold well, it is likely that one of the coils has failed. If the magnet does not
work at all, it is likely to be a failed rectier. (It is highly unlikely that both magnet coils would fail at the same
time)
NOTE: A faulty magnet coil can also damage the rectier, so whenever there is a magnet problem, BOTH
the magnet coils and rectier must be checked.
WARNING: Never attempt to operate a magnetic drill with a faulty magnet!
