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, without any 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.
CARBON BRUSHES
Due to the brush design, if the machine comes to a stop without any
reason, the brushes have to be checked. The brush design 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 rectifier. (It is highly unlikely that both magnet coils would fail at the same
time)
NOTE: A faulty magnet coil can also damage the rectifier, so whenever there is a magnet problem, BOTH
the magnet coils and rectifier must be checked.
