Section 1: Safety! 1-3
SAFETY REQUIREMENTS FOR STRINGPIN PINSETTERS
As with all machinery, a certain amount of risk is involved in working on the StringPin Pinsetter.
However, if the necessary care, knowledge and responsibility are exercised, damage to the pinsetter and
people involved in accidents can be avoided. The following steps should be taken:
Safety Guidelines
1. ONLY PROPERLY TRAINED PEOPLE ARE QUALIFIED TO WORK ON OR OPERATE
THE PINSETTER.
2. Never operate the pinsetter without ALL factory supplied guarding in place.
3. Never operate the pinsetter if a guard or safety device is damaged or improperly tted to the
machine.
4. Never bypass, disable, or tamper with the safety switches or pinsetter function switches.
5. Never attempt to climb over or around any mechanical barrier or machine guard.
6. Reinstall all the machine guards and the ladder after any troubleshooting or maintenance work
has been done on the pinsetter(s) or ball accelerator.
7. Always face toward the machine when using the ladder to climb onto or o the machine. Only
one person should be on the ladder at any time.
8. Suitable clothing must be worn (for example: rubber-soled shoes). Do not wear loose clothing
such as neckties or smocks that could get caught in moving parts. Remove rings, watches,
earrings, bracelets and other jewelry to avoid injury.
9. Care should be taken while near the front of the machine. Accidentally blocking the photocell
beam may cause the pinsetter to cycle.
10. Always turn the pinsetter o before working on the machine. Use the Stop/Run Switches
mounted on the rear or front of the pinsetter to turn o the pinsetter.
11. If more than one person is working on a machine or if a stop/run switch will be out of reach
while working on the machine, turn o both stop/run switches to prevent a person from turning
on the pinsetter before the other person says he/she is clear of the pinsetter.
12. When working on both machines of a lane pair or components that are common to both
machines (for example: the ball accelerator) power must be turned o at the StringPin Pinsetter
Controller. In addition, the main power switch on the StringPin Controller must be locked into
the o position using a suitable locking mechanism.
13. Fire extinguishers must be on hand and maintained properly. Keep oily rags and other
combustibles in approved re proof containers.
14. If more than one person is working on a machine, be sure the other person is CLEAR before
restarting the machine.

1-4 Section 1: Safety!
15. When working in the pinsetter area while machines are in operation, ear protection should
be worn. Sound levels greater than 83db can be experienced within 1.6 meters of operating
machines.
16. Never work on or around the pinsetter while under the inuence of alcohol, drugs, or any other
substance that can impair your physical abilities or mental judgment.
17. Always use the correct tools for the job.
18. The StringPin pinsetter is designed for use as a 10 pin bowling machine. Do not use the
machine or any of its subassemblies for any other purpose.
19. Poisonous or toxic cleaners must not be used. Always check the material safety data sheets
before using new cleaners.
20. Always use factory approved parts when repairing the pinsetter. Using substandard parts may
pose a safety risk.
21. Always make sure that a bowler is not positioned to throw a ball before putting yourself
between the bowler and the machine. It is good practice to have another employee positioned
near any bowler to ensure they cannot throw a ball. Additionally, make sure to properly secure
a Brunswick Ball Stop or similar 3rd party product to the lane between you and the bowler for
added protection.

Section 2: Overview 2-1
Section 2 - Overview
This manual is designed to help you service, repair, and perform preventive maintenance on your
pinsetters in a safe and ecient manner. Prior to working on one of these pinsetters, you should read the
safety information and be familiar with the Safety Requirements located at the beginning of the manual.
This manual also provides troubleshooting guidelines that will help reduce downtime and can be used
to provide years of reliable operation of your pinsetters.
OPERATION AND CYCLES
Turning the Pinsetter On/Off
The pinsetter can be turned o using the Stop/Run switches located at the back or front of each
individual machine or on the String Pin Controller box. Always turn the Pinsetter o before working

Actions That Start a Machine Cycle
Any of the following occurrences will cycle the pinsetter.
1. Pushing the reset button on the ball rack.
2. The pulling of a string attached to a pin such as when a bowling ball knocks over one or more
pins along with a ball detect signal from the pinsetter ball detector.
3. The second ball in a frame breaking the pinsetter ball detector.
4. Switching the main power located on the StringPin Controller to the “On” position.
5. The scoring system sending the pinsetter a “Reset” command through its communication cable.
Description of Pinsetter Cycles During Bowling
First Ball Cycles
Strike
Three seconds after the rst pin falls, all ten pins are raised to the full up position and then lowered to
the pindeck.
Gutter Ball (Bowling ball rolled in the channel)
The machine will receive and remember the ball detect signal. There is no machine activity and after
ve seconds the machine is ready for the second ball.
Some Pins Knocked Down (Standing Pin Cycle)
Three seconds after the rst pin falls, all ten pins are raised to the full up position and those that were
left standing will be lowered to the pindeck.
Second Ball Cycles
Three seconds after receiving a ball detector signal all ten pins are raised to the full up position and then
lowered to the pindeck.

Section 2: Overview 2-5
PINSETTER GUARDING
The StringPin Pinsetter is equipped with guards to prevent injury and to limit access to moving parts
of the pinsetter. Two guarding options are available; UL certied and CE Certied. UL Certied
guarding is the standard guarding for centers outside the European Union while CE Certied guarding
is required for centers in European Union countries as well as all residential installations. Refer to
Figure 2-4 and Figure 2-5 for an explanation of all pinsetter guarding.
Brunswick strongly encourages all centers to consider upgrading to
Brunswick’s CE Certied guarding.
WARNING! Do not operate the pinsetter without the guarding in place. Severe
injury could result if the pinsetter guarding is not used while the machine is
operating.

Section 2: Overview 2-9
MACHINE COMPONENT LOCATION AND DESCRIPTION
The simple design of the StringPin pinsetter makes it easy and inexpensive to operate and maintain.
Because the pins are tethered to the machine by the “strings”, only 10 pins are required rather than the
20 - 23 pins typically used in free fall pinsetters. The design also eliminates the need for additional
components required to collect pins and move them through the machine. This reduces the noise and
pin handling issues associated with free fall pinsetters. Refer to Figure2-9.
The StringPin Pinsetter consists of four subassemblies:
1. Main Frame (Drive Motor, String Spool, Pin Motion Interface)
2. Setting Platform (Centering Cones)
3. Ball Pit (Ball Stop, Carpet Mat, Pit Assembly)
4. Ball Accelerator
