Installing the Outer Arm
The Outer Arm is used to automatically establish the Diameter of the Wheel being balanced.
Important:
To install the Outer Arm:
1. Locate the Outer Arm Mount Bar, the Outer Arm, and the Hex bolts required to connect them.
– The Outer Arm Mount Bar connects to the Mount Box using four 5 mm hex bolts, four split
lock washers, and four standard washers. These come in place on the Mount Box.
– The Outer Arm connects to the Outer Arm Mount Bar using one 4 mm hex bolt, one split lock
washer, and one large black plastic washer. These come in place on the long piece connected
to the Outer Arm counterweight.
2. Remove the four 5 mm hex bolts, four split lock washers, and four standard washers from their
location on the Mount Box.
3. Connect the Outer Arm Mount Bar to the Mount Box using the four 5 mm hex bolts, split lock
washers, and standard washers you just removed. Tighten securely, but do not overtighten.
4. Remove the 4 mm hex bolt, split lock washer, and large black plastic washer from the end of the
Rod connected to the Outer Arm counterweight.
5. Slide the Rod through the Tube on the Outer Arm Mount Bar, then reattach the 4 mm hex bolt,
split lock washer, and large black plastic washer you just removed. Tighten securely, but do no
overtighten.
6. Run the Cable coming off the Outer Arm through the clips on the underside of the Outer Arm
Mount Bar, then connect the fitting on the end of the cable to the appropriate Connector.
The Display Panel Cable Connector has three holes in it.
