Saddle Gib
Tools Needed:
Qty
Hex Wrench 3mm .................................................1
Before making adjustments to the saddle gib,
make sure the carriage lock (see Figure 44 on
Page 37) is loose by turning it counterclockwise
one full turn.
To adjust saddle gib:
1.
DISCONNECT LATHE FROM POWER!
2.
To tighten saddle gib, tighten set screws (see
Figure 92). To loosen gib, loosen set screws.
Note:
Be sure to adjust all set screws the
same amount. This will ensure even wear of
gib and sliding surfaces.
3.
Move carriage back and forth, repeating
adjustments as necessary, until saddle
movement is acceptable.
Belt Tension &
Replacement
The timing belt transfers power from the motor
to the drive pulley.
Because the molded teeth in the belt fit together
with matching teeth in the pulley, the timing belt
will not slip unless the belt teeth become overly
worn or belt tension is overly loose.
An improperly tensioned timing belt will slip,
which quickly causes it to become damaged
and unsuitable for further use. Therefore, it is
essential to maintain belt tension properly to
prevent slippage.
Once a timing belt begins to slip, it must
be replaced in order to regain proper power
transmission.
