Movable Arm Inspection Inspect the moveable arm for cracks every 24,000 miles (38,600 km), 3 months, or 900 operating hours, whichever occurs first. 4. Use the cloth to clean the exposed surface of the steel plate on the moveable arm. All dirt and grease needs to be removed. Dynaflux cleaner may be applied directly to the plate if needed. ☞NOTE: This maintenance interval may need to be adjusted to suit the specific operating conditions and geographic location. Exposure to slush, salt, and/or sand will require more frequent inspection. If the unit is subjected to spray or pressure washing, then it will be necessary to relubricate immediately following cleaning. 1. Remove the brake treadle. Refer to your New Flyer Service Manual for removal procedure. 2. With the brake treadle removed, rotate the moveable arm up such that it sits in a nearly vertical position and the steel plate on the underside is easily visible. See “Fig. 1: Moveable Arm Inspection” on page 3. DO NOT loosen screws or remove the steel plate from the moveable arm casting. 5. Allow 5 minutes for the cleaner to evaporate such that the plate on the moveable arm is completely dry and clean. The red penetrant may stain skin if not protected. 6. While wearing latex gloves and safety glasses, spray a medium wet coat of Dynaflux PHF315-16 penetrant onto the surface of the steel plate. ☞NOTE: DO NOT remove the moveable arm assembly unless replacing with maintenance kit. Refer to PMB-049 for kit part number. Avoid excess overspray on nearby components. 7. Allow the penetrant to soak for a minimum of 10 minutes. 8. Saturate an area of a clean cloth with Dynaflux cleaner and thoroughly wipe away the penetrant from the steel plate. ☞NOTE: Read warnings and follow guidelines printed on Dynaflux chemical containers. DO NOT spray cleaner directly onto the plate. 3. While wearing safety glasses and gloves, liberally spray Dynaflux CNF315-16 cleaner onto a clean cloth so as to saturate a small area of the cloth. 9. Allow 5 minutes for the cleaner to evaporate, and then apply an even coat of Dynaflux DNF315-16 developer to the steel plate. 2 of 5 The New Flyer vehicles described in this manual may be protected by one or more patents and design applications or registrations in the United States and Canada, and in other countries.
