Return a ball through the ball lift and observe the braking action of the transition
blocks. The momentum of the ball should be significantly reduced, and the ball
should not jump or bounce. Inspect the urethane transition pads. Replace them
before they become so worn that they allow the bowling ball to contact metal, or if
they are badly gouged or no longer function adequately to slow the ball as it exits the
Ball Lift.

Inspect the Ball Lift’s upper and lower guide strips as well as the left and right side
wear strips for excessive wear, especially where the ball enters the lift and where the
ball transitions onto the upper guide strip. These are very long-wearing components,
but occasionally one may need to be replaced. Also, replace any missing plastic
rivets (938-101-005) and tighten any loose hardware.
Inspect the upper and lower V-wheels. These items are very tough and should
provide a very long life, but can be damaged from use. To replace a V-wheel,
remove the three bolts that secure it to the upper or lower shaft assembly and install
a new wheel in its place. Tighten the three bolts securely.
Check the operation of the safety switch. The guard should pivot freely, and when
actuated, the Ball Lift should turn off immediately and sound an audible alarm.
Lubricate the pivot shaft sparingly as needed where it passes through the side
plates. Reset the switch actuator and return the Ball Lift to the NORMAL Mode.
Wipe up or vacuum out any accumulated debris. Inspect the brackets for damage
and check for the smooth operation of the pulleys, bearings, etc. With the belt
removed, the lower large pulley wheel should be capable of rotating independently
of its associated V-wheel when turned in the clockwise direction, but should
immediately lock up and rotate as a unit with the V-wheel when rotated in the
counterclockwise direction. This arrangement allows the V-wheel to momentarily
rotate faster than the pulley without causing stress to the drive components when a
ball first enters the Ball Lift.
For replacement part numbers, refer to the Drawings and Part Numbers section at
the back of this manual.
