5.1.3 Conditioning Operation, continued
The machine hums or
chatters when it is buffing.
The buffer brush pressure is too high. Reposition the buffer
brush to reduce the pressure. Check for sufficient buffer belt
tension. Refer to Section 4 – Maintenance and Adjustments
for information about adjusting the buffer brush.
The buffer brush doesn’t lift
off the lane when it has
reached the distance at
which it should stop buffing.
Check the buffer return springs. The springs should be
connected to buffer spring brackets on either of the rear
frame corners.
Ensure the clevis pin(s) has not come out of the clevis.
If the springs no longer have sufficient tension, or if a clevis
pin(s) has broken, replace them. Refer to Section 7 - Parts
for part numbers.
There are streaks in the oil.
Check the squeegee. The smooth side of the squeegee
should be the side that glides along the lane. Reposition the
squeegee so that the smooth side faces down on the lane.
Additionally, check to make sure the nuts holding the
squeegee to the vacuum head aren’t too tight. This can
cause the squeegee to buckle. If the squeegee is buckled,
adjust the tightness of the nuts until smooth.
If this problem persists, the squeegee may need to be
replaced or the vacuum head height may need to be
adjusted. Refer to Section 7 - Parts for part numbers and
Section 4.3.5. – Adjusting the Vacuum Head Height.
