Foredom Series H Motors - Manual

Special Insert for Assembly,
Operation, and Maintenance of
Series TXH, SRH, LXH, and H Motors
The models shown at right come equipped with longer, square
drive shafts and heavy duty protective sheaths that are different
from those on our standard TX, SR, and LX motors.
As a result, they can only be used with Foredom’s four square
drive style handpieces.
Aside from the assembly and maintenance of these unique items,
all other operating instructions and safety guidelines apply. Please
read manuals carefully and completely.
Square Drive Handpieces for TXH, SRH, LXH,
and H Motors
These handpieces are used with heavy duty “square drive”
shafts ONLY. They are unique products and not part of Foredom’s
system of interchangeable handpieces. They have permanently
lubricated and shielded ball bearings for cool running and
continuous use. H.25H, H.30H, and H.44HT have positive sheath
locking mechanisms (locking rings). The new H.28H attaches
without a locking ring.

FOREDOM ® Replacement of Motor Brushes
Motor brushes should be checked for wear periodically.
When new they are approximately 3/4 ″ (19mm) long.
Replace them when they have worn to 1/4 ″ (6mm). To
remove brushes, disconnect motor power cord and
unscrew the brush caps. Remove the worn motor
brushes, replace with new motor brushes, and screw
motor brush caps back on. Be sure to replace both
motor brushes even if one of them seems less worn
than the other. New Motor Brush Motor Brush that
needs replacement
