CCAAUUTTIIOONN
• Improper usage of the product can cause injury to the patient or operator. Operate the product only as described in this
manual.
• Do not modify the product or any components of the product. Modifying the product can cause unpredictable operation
resulting in injury to patient or operator. Modifying the product also voids its warranty.
• Do not steam clean or ultrasonically clean the product.
• Do not exceed 180 °F (82 °C) as the maximum water temperature.
• Do not exceed 1500 psi (130.5 bar) as the maximum water pressure. If you are using a hand held wand to wash the

1. Using the 5/32" hex wrench and 7/16" combination wrench or socket, remove the socket screw from the center of the
lock pedal. The wheel lock is initially assembled with the pedal set at the minimum locking force. The marker on the
pedal (A) is aligned with the marker on the octagonal sleeve (B) (Wheel locking force adjustment).
2. Remove the sleeve (B). Rotate the sleeve counterclockwise to increase the pedal locking force and clockwise to
decrease the locking force. Insert the sleeve into the pedal (Wheel locking force adjustment).
3. Using the 5/32" hex wrench and 7/16" combination wrench or socket, reinstall the socket screw.
4. Test the pedal locking force and make sure that the pedal holds properly before returning it to service.
