Important Note
To reduce wear and noise, apply two drops of oil to the carriage rod:
1. One drop between the carriage bushings.
2. One drop in the center of the carriage rod.
Be sure to use a synthetic, low vapor-pressure oil that is compatible with the plastic parts and resistant to
evaporation. If this type of oil is unavailable, use one (1) drop of sewing machine oil between the car-
riage bushings.

toward the carriage to release the tension supplied by the spring (see Figure 6.12.11).
