    SAFETY General Safety Guidelines AMF believes strongly in its commitment to safety. Proper service and repair are important to the safety of the mechanic as well as the safe, reliable operation of the pinspotters. Please read, understand, and follow all of the recommended safety procedures presented in this manual.
  • Page 10 AMF 90XLi PINSPOTTER Safety Labels and Symbols It is important to understand the safety labels and symbols used in this manual set. Three of these labels are used to show the relative risk associated with a particular activity or instruction. These labels are shown below in order of decreasing importance.
  • Page 11 SAFETY Safety – Refer to the Service Manual before performing maintenance or repair. – Caution! Severe pinching hazard - belts. It is also important to understand that the use of these symbols and labels is not all- inclusive because it is impossible to warn of all the possible hazards and consequences that could result from failure to follow these instructions.
  • Page 12 AMF 90XLi PINSPOTTER Guards and Safety Precautions All safety guards must be in place before operating the machine. When maintenance is required, the following steps must be followed: 1. Disconnect the power plug before working on the pinspotter. 2. Remove guards only as required to perform the maintenance.

  • Page 16: Positive Ball Lift Description

    The purpose of the ball lift is to raise the ball high enough to permit a gravity return to the bowler. The 90XLi Pinspotter’s Positive Ball Lift is equipped with AMF’s Gripper Ball Lift system ensuring reliable operation even with today’s heavily oiled lanes. The ball lift consists of a number of separate assemblies that work together to achieve the desired result.

  • Page 17: Positive Ball Lift Belt Adjustment

    SECTION 2.0 Operation & Adjustment 7. If the ball lift is not aligned with the track rails: Rotate the ball lift support shafts so that the slots in the adjustable plates are in line with the direction of offset between the support brackets on the kickback plates (see Figure 2-2).

  • Page 18: Sensor Assembly Operation

    AMF 90XLi PINSPOTTER Sensor Assembly Operation The cam follower roller must be low enough so that it will slide under the rudder cams when paddle movement is blocked, but high enough so that the rudder cams will lock behind it in the power drive position (see Figure 2.4).

  • Page 19: Rudder And Sensor Adjustment

    SECTION 2.0 Operation & Adjustment Rudder and Sensor Adjustment 1. Remove the retaining nut from the crank pin and save (see Figure 2-6). 2. Remove the rod assembly from the crank pin and swing it out of the way so that the sensor assembly can be moved manually.

  • Page 21: Trip Cam Adjustment

    SECTION 2.0 Operation & Adjustment Trip Cam Adjustment 1. Turn the drive pulley to place the rudder in the center of its travel (center of ball lift). 2. Push the trip cam followers forward as far as they will go. There should be a 1/8-inch gap on each side between the trip cam and rollers (see Figure 2-8).

  • Page 22: Checking The Reset Cams

    AMF 90XLi PINSPOTTER 2.10 Checking the Reset Cams 1. Manually rotate the rudder drive pulley. While the sensor is moving back and forth, move one of the trip cam follower rollers towards the rear of the machine. Continue rotating the drive pulley until the roller contacts the reset cam, returning the trip cam follower roller to its normal (forward) position.

  • Page 23: Positive Ball Lift Assembly Adjustment

    SECTION 2.0 Operation & Adjustment 2.11 Positive Ball Lift Assembly Adjustment 1. The Positive Ball lift assembly must be centered between the return rails (see Figure 2-9). To adjust, loosen the nuts on the four clamp studs in the upper and lower mounting brackets, adjust the lift from side to side as needed, and retighten the nuts.

  • Page 24: Lift Arm Adjustment

    AMF 90XLi PINSPOTTER 2.12 Lift Arm Adjustment 1. Measure the height of the lift arm above the door weldment (see Figure 2-11). This distance should be no more than 1/8 inch. Adjust this gap by adjusting the length of the rod that connects between the lift arm and the ratchet drive assembly (see Figure 2-12).

  • Page 25: Rubber Bumper Adjustment

    SECTION 2.0 Operation & Adjustment 2.13 Rubber Bumper Adjustment 1. Place a bowling ball on the lift arm assembly (see Figure 2-13). 2. Measure the clearance between the ball and the ball lift belt. This clearance should be between 3/8 and 1/2 inch. The increase in clearance from earlier units is needed because of the thicker rail covers of the new Gripper ball return.

  • Page 27: Lubrication Instructions

    SECTION 3.0 Lubrication LUBRICATION INSTRUCTIONS LUBRICATION Lubrication is one of the most important items in the proper operation and maintenance of the Positive Ball Lift. Care must be taken to insure that lubricants are applied correctly. Avoid excessive lubrication to minimize the possibility of transmitting lubricants to the bowler.
