Inserting sample coin or token, Adjusting selectivity, Cleaning your slugbuster – Laurel Metal Slugbuster User Manual
Page 2

To insert or change the sample coin:
1. Locate the sensing coil on your unit
2. Slide it in the direction of the arrow on the label, against the
spring tension and remove the existing sample
3. Insert a new sample coin or token into the sensing coil and
allow the spring tension to tighten the sensing coin against
the sample. The sample must be centered under the sensing
coil and firmly seated between it and the coin slide rail, as shown.
Adjusting Sensitivity
Do not adjust the selectivity unless your unit malfunctions as described in ‘Testing’ on page 1.
Your Slugbuster has been factory pre-set to accept US quarters and reject common slugs. If you wish to use a sample other than a
US quarter, first insert your sample (see ‘Inserting Samples’ above). Then check the unit’s performance as described in ‘Testing’ on
page 1 to determine if you need to readjust the selectivity for your sample.
Use caution when adjusting the selectivity trim pot (potentiometer). It is extremely sensitive and very little movement will cause a
change in performance. The full range of movement is 240°, or less than one turn. If you turn it too far either way, it will break and
void your warranty. Turn the trim pot counter-clockwise (ACCEPT) to accept more borderline coins or tokens; turn clockwise
(REJECT) to accept fewer kinds of slugs. NOTE: the unit must be powered up to make these adjustments.

For best results, use this procedure to adjust the selectivity:
1. Locate the sensing coil on your Slugbuster. There must be a sample coin or token in the sensing coil;
check to be sure the sample is centered in the sensing coil and properly seated and secured.
2. Remove the plug from the lower right corner of the electronic box lid, exposing the selectivity trim pot.
3. Using a plastic stylus, turn the selectivity trim pot fully clockwise (REJECT). This should make the unit
reject all coins, tokens and slugs.
4. Begin dropping your good coins into the unit, slowly turning the trim pot counter-clockwise until your
Slugbuster begins to accept them. Turn the pot an additional 2-5 degrees counter-clockwise and stop.
5. Replace the plug in the trim pot. This completes the adjustment.
If the unit is accepting incorrect coins, turn pot counter-clockwise;
If the unit is rejecting good coins, turn pot clockwise
.

After Completing the Selectivity Adjustment, repeat the Testing Procedure on page 1.
When you are satisfied that you have the unit adjusted properly, be sure to REPLACE THE PLUG to protect the
electronics from dirt and water damage. Installing the unit without the plug in place may void your warranty.
Cleaning Your Slugbuster
Clean your Slugbuster with a soft cloth and warm water. DO NOT use oil or other corrosive liquids.
