See the following pages. Urschel recommends that customers operate the machine only if it has a brake motor. The goal of Urschel is to help ensure a safe machine operating environment. Urschel can provide a quote for a brake motor or brake repair parts.
Supplement Brake Maintenance Testing the Brake WARNING Qualified trained personnel are required to perform this test. Any problems found during this test must be corrected by qualified personnel before the machine is operated, or serious injury such as amputation could result. IMPORTANT Excessive heat from frequent stops at short intervals can damage the motor and brake.
Adjustment and repair information is the same for earlier versions except as noted. Older machines used an earlier brake model; contact your Urschel representative for replacement information. WARNING According to the brake manufacturer, inhaling dust from inside the brake may be dangerous to your health.

Supplement Brake Maintenance 4. Adjust the air gap. Use a 3/16" hex wrench or flat screwdriver on older models. To decrease the air gap, turn both adjusting screws (1) clockwise. To increase the air gap, turn both screws counterclockwise. Turn the screws evenly, 1/8 turn, then manually depress the plunger.
Supplement Brake Maintenance Replacing the Friction Discs 1. Disconnect and lock out the power supply. Remove the housing. 2. Remove the support plate assembly (1). Three screws hold the assembly in place. The wires to the solenoid coil can remain attached. Support the assembly so that wires are not damaged;...
Supplement Brake Maintenance Replacing the Solenoid Coil The solenoid coil (1) used in the 10 pound-foot brake on a standard machine is a multiple voltage and dual frequency coil with four leads* (also called a quad coil). For a machine with direct-on-line starting, power is supplied to the coil from the motor windings.

Supplement Brake Maintenance 4. Replace the coil (1). Remove the plunger guide (2). Use a screwdriver to push up on the catch (3) on the bottom of the coil. Slide the coil out of the frame (4) and discard. Install the new coil and plunger guide.
S.10 Supplement Brake Maintenance Replacing the Brake Assembly Check the power requirements and verify the voltage before ordering a brake assembly. 1. Disconnect and lock out the power supply. 2. Remove the brake assembly. Remove the housing. Check the wires (1) at the terminals and verify that the markings on the insulation are legible.
Page 13
Supplement S.11 Brake Maintenance 3. Disassemble the new brake assembly. Remove the housing from the brake assembly. Remove the support plate assembly (1). Push the hub out of the end plate. If additional wires (2) are included at the terminal strip, remove the wires and discard.
