INSTALLATION INSTRUCTIONS FOR
DSP9600/9100 WHEEL BALANCER
This document provides the information needed to install the DSP9600/9100 Wheel Balancer.
NOTE: Installation of the DSP9600/9100 Wheel Balancer should be completed only
by an authorized Hunter Service Representative.
Placement
The balancer should be placed in a dry area, which is not subjected to moisture. Clearance for the operator at the
front and to the right of the balancer should be at least 3 feet (0.91 meter). There must also be ample clearance at
the rear of the balancer to allow the safety hood to fully open. The electrical power cord should be positioned so
that it cannot be walked on, driven over, or tripped over.
Floor Requirements
The balancer should be placed on a solid concrete floor. Any floor condition that might allow the balancer to
move during operation is unacceptable.
If the location selected is a cement floor that is hollow underneath, place the balancer over a supporting beam or
close to a supporting wall.
Power Requirements
The customer must furnish a 230 volt (208 - 240), 50/60 Hz, 20 AMP single-phase electrical supply for the
balancer. This machine must be connected to a 20 amp branch circuit. Refer all power source issues to a certified
electrician.
The power cord supplied utilizes a twist lock connector, NEMA L6-20P. The receptacle may need modification to
allow the proper connection of the power cord.
Changes to the electrical power cord, plug, and/or power source must be performed by a certified electrician in
accordance with local electrical codes.
Air Supply Requirements
The customer must furnish a 90-145 psi (6.21–10.00 bar) air supply line. Necessary only for balancers equipped
with the optional wheel lift and/or Inflation Station™features. A moisture trap and/or filter may be necessary to
provide clean, dry air.
Special Tools Required
•Silicone or Teflon Grease
•Calibration Tool, 221-602-1 (for Dataset®Arms)

to prevent the arm from returning to the “home” position.
5. Lift the weight tray up and forward off the base.
6. Place the Inner Dataset® Arm back into its home position.
7. Place the hose back into the optional Inflation Station™holder.
Install Safety Hood:
NOTE: It is recommended to use an assistant during this portion of installation.
1. Apply a coating of silicone or Teflon grease to the hood shaft. The hood shaft is the bearing surface of the
hood assembly.
2. Place the thin steel washer, 77-248-2, on the hood shaft.
3. Slide the hood assembly, 69-1026-1, onto the shaft.
4. Verify that the plastic bushings on each end of the hood shaft are flush. If they are not flush, a soft head
hammer may be used to adjust the bushings.

Install Weight Tray:
1. On DSP9600, remove hose from optional Inflation Station™holder and drape over spindle shaft.
2. Slide the Inner Dataset®Arm out past the hub. Tilt the arm so that it catches on the hub. The hub will prevent
the arm from returning to the “home” position.
3. Place the weight tray on the DSP9600/9100 base assembly.
NOTE: When installing the weight tray, it may be necessary to lift up on the rear of
the weight tray, while pushing the weight tray backward into position.
4. Secure the weight anvil to weight tray with two socket head bolts previously removed.
5. Secure the weight tray to the base with the Phillips head screw previously removed from the weight tray’s
front left corner.
6. Place the Inner Dataset®Arm back into its home position.
7. Place the hose back into the Inflation Station™holder, if so equipped.
8. Connect the electrical power cord to the AC power source.
Weight Tray Decal Installation:
Place the weight tray decals, 128-421-2, on the indentations above the weight tray pockets.
Verifying the Hub and Shaft Installation:
Using a dial indicator, measure hub face and shaft runout. Runout on the hub face should not exceed 0.0015
inch. Runout on the shaft should not exceed 0.0015 inch. If runout exceeds these limits, replace the hub/shaft
assembly.

Switch Test
1. Connect electrical power cord to AC power source and air supply line to the air inlet (if necessary).
2. Turn the DSP9600/9100 Balancer “ON” while holding the Right and Left Split Weight buttons during power up
to enter “Diagnostic Mode.” Press the “Next” button to begin showing diagnostic variables.
3. Dial the “D” knob to diagnostic item number 36. Zero will be displayed on the right digits.
4. Press all buttons and close all switches. Each switch closure should be followed by a beep indicating that the
switch is functioning.
5. Dial the “D” knob clockwise to exit the switch test.
Verify Installation of Auto Dataset Arm(s) (DSP9600 only):
1. While in “Diagnostic Mode,” press “Next” to verify that the wire connection for the Inner and optional Outer
Dataset®Arms are correct:
a.) Dial the “D” knob to diagnostic item number 28. Move the Outer Dataset®Arm in a horizontal
line from right to left. The real-time numbers displayed on channel 28 on the screen should
increase.
b.) Dial the “D” knob to diagnostic item number 26. Move the Inner Dataset®Arm in a horizontal
line from left to right. The real-time numbers displayed on channel 26 on the screen should
decrease.
c.) Dial the “D” knob to diagnostic item number 27. Move the Inner Dataset®Arm in a vertical
line upward. The real-time numbers displayed on channel 27 on the screen should increase.
d.) If the numbers are not behaving as described above, the cable connections are reversed and
need to be exchanged.

move the beam. However, the mounting position of the beam must be
verified with the tire/wheel assembly in place.
19. Lift the end of the beam slightly when tightening the bolts to close the gap between beam mounting plate and
the attachment blocks.
NOTE: Ensure that the four bolts securing the beam’s mounting plate to the
attachment blocks are completely tightened.
20. To verify proper operation of the wheel lift assembly, remove the tire/wheel assembly from the trolley, raise
the wheel lift, and then close the hood of the balancer. Lifting beam and trolley should lower automatically.
