The E-clips have been a problem
on these vehicle lift platforms.
So much so that I recommend
stocking a couple of these Eagle
Lift clips to reduce down time.

We have had many pingame coin

cashboxes.

Every three months check to
make sure that the wheels that
the cable runs over are turning.
Very important. This inspection
can save you a cable from being
damaged. This item also applies
to Tommy Gate lift platforms.
CAUSE
This condition is caused by a
non-linear vertical waveform. -
as viewed with the oscilloscope
at TP3.
SownoN
Change capacitor C9 (100uf,
35V) in the vertical amplifier
circuit.

Due to the forward pitch of th~.
cabinet, the coins tend to pile up
towards the front of the box,
causing the coins to back up into
the coin mechs.
SownoN
A redesign with a backwards
pitch of the cashbox would
eliminate this annoying problem.
