To remove a steel mini post : The first step is to firmly grasp the rubber ring and pull it straight up, off of the post.
Locate the washer and nylon stop nut for the post under the playfield. Using the ratchet and 1/4", deep socket from
above and the 3/8" open end wrench from below, remove the nylon stop nut and washer from the bottom of the
post. Apply firm pressure to the bottom of the post while slowly continuing to back the post out of the playfield
with the ratchet. WARNING : DO NOT simply pull the post out; you can damage your playfield surface!
To install a steel mini post
: Carefully align the threads of the post with the hole and begin "threading" it, by hand,
into the hole (slowly turning it in a CW direction). When it becomes difficult to turn the post by hand, use the
ratchet and 1/4", deep socket to continue "threading" it into the playfield. When the threads of the post sufficiently
protrude from the bottom of the playfield, install the #10 washer and 10-32 nylon stop nut. Using the ratchet and
socket from above and the 3/8" open end wrench from below, carefully tighten the nylon stop nut until the post is
pulled all the way down to playfield surface level and firmly held in place. You should not be able to move the post
at all by hand when you are done. DO NOT OVERTIGHTEN ! Lastly, install the post rubber ring, by sliding it over the
top of the mini post.
To remove a plastic post and screw : Locate the washer and nylon stop nut for the post under the playfield. Using
the #2 Phillips screwdriver from above and the 11/32" open end wrench from below, remove the nylon stop nut and
washer from the bottom of the post screw. Carefully pull the plastic post and screw straight up, out of the playfield.
To install a plastic post and screw : Install the rubber ring by sliding it over the top of the plastic post. Push the
8-32 machine screw through the center of the plastic post; ensure that you have the post upright. When upright,
the rubber ring will be positioned slightly above the middle of the post. Feed the bottom of the screw through the
playfield hole and install the #8 washer and 8-32 nylon stop nut from underneath. Using the #2 Phillips screwdriver
from above and the 11/32" open end wrench from below, carefully tighten the nylon stop nut until the plastic post
is pulled all the way down to playfield surface level and firmly held in place. You should not be able to move the
post at all by hand when you are done. DO NOT OVERTIGHTEN !
