INSPECTION, MAINTENANCE, AND CLEANING
1. WARNING! Make sure the Pipe Threader is disconnected from its electrical
outlet prior to performing any inspection, maintenance, or cleaning procedures.
2. Before each use, inspect the general condition of the Pipe Threader. Check for
cracked or broken parts, damaged electrical wiring, damaged Die Blades, and
any other condition that may affect safe operation. If abnormal noise or vibration
occurs, have the problem corrected before further use.
Do not use damaged equipment.
3. To replace the Motor Carbon Brushes: It may become necessary at sometime
to replace or clean the two Carbon Brushes (36) when the Motor performance
decreases, or stops working completely. The Carbon Brushes are located on
each side of the Motor Housing (33). To replace the Carbon Brushes, remove
the two Brush Holder Covers (37). Then, remove the two Carbon Brushes from
the two Brush Holders (35). If either Carbon Brush is worn down more than
halfway, replace
both
Carbon Brushes. If the Carbon Brushes are just dirty,
however, they may be cleaned by rubbing them with a pencil eraser. When
reusing Carbon Brushes, reinstall the brushes in the same orientation as
previously to prevent excess wear. When installing the Carbon Brushes, make
sure the carbon portion of the Carbon Brushes contact the Motor’s Rotor (27) and
that the springs face away from the Motor. Also, make sure the springs operate
freely. After replacement or cleaning, replace the two Brush Holder Covers.
NOTE: New Carbon Brushes tend to arc or spark when first used until they wear
and conform to the Motor’s Rotor. (See Figure I.)
4. To replace the Die Blades: Worn Die Blades (55, 55A, 55B, 55C) can result in
poor thread quality. When replacing Die Blades, make sure the size of the new
Die Blades correspond to the size of the Die (1/2”, 3/4”, 1”, or 1-1/4”). To replace
the Die Blades, remove the four Screws on the Die. Remove the Chrome Ring
from the Die. Then, remove each of the
four
Die Blades. Once removed, insert
BRUSH HOLDER COVER (37)
CARBON BRUSH (36)
BRUSH HOLDER (35)
