Rev. K, p. 2 of 19 DESIGN CONCEPT Curtis cabs feature an assembly of parts designed for your vehicle which require adjustment and alignment of components to accommodate vehicle variations and provide proper weather protection. For accurate installation, proper operation, and years of satisfaction, please read and understand the installation instructions. From all of us at Curtis, we thank you for choosing our product. ADDED WEIGHT Curtis Cabs, blades and general accessories add additional weight to the base vehicle. All Curtis accessory weights are listed in product brochures. Deduct the accessory's total weight from the vehicle's rated capacity and never exceed the vehicle's rated capacity including driver and passenger. Exposure to Carbon Monoxide can Cause illness, serious injury or death. Never operate vehicle if suspicious of Carbon Monoxide. Inspect exhaust system for leaks monthly. Leaks can result from loose connections, corrosion, cracks or other damage to the exhaust manifold. If leaks are found, repair or replace exhaust system. Do not use vehicle until repair or replacement is complete. CAB INSTALLATION BEFORE YOU START HELPFUL REMINDERS: A. Refer to parts diagram toward the back of this manual to help identify parts during the assembly process. B.

Although the mounting surface may appear clean, it is required that the surface be cleaned with isopropyl alcohol or an acetone or ammonia-based cleaner immediately prior to application of the sound barrier material. Allow cleaned surfaces to dry thoroughly. Good surface contact is required to achieve bond. Failure to follow these steps can result in the separation of the sound barrier material from the mounting surfaces. NOTE: paint thinners or products with any oil in them will not work and are detrimental to the proper cleaning of the underside of the fender. NOTE: clean rags are very important.

Rev. K, p. 12 of 19 CARE AND MAINTENANCE (IMPORTANT: be sure to leave this page with the owner once installation is complete. Check and tighten hardware after 40 hours of operation. Periodically inspect and tighten hardware for the remainder of the unit s service life. IMPORTANT CLEANING INFORMATION Keep the enclosure components clean in order to prevent dust and dirt from forming an unattractive film. The life of your roof, glass windshield, acrylic rear window, and doors depends upon following these care procedures: GLASS WINDSHIELD: 1) Clean with any conventional glass cleaner. Do not use on rear window. See below. ACRYLIC REAR WINDOW: 1) NEVER USE AN ALCOHOL-BASED PRODUCT FOR CLEANING. Do not use WINDEX, GLASS PLUS, FANTASTIC, etc. Use of these products will result in deterioration of the acrylic item. 2) To clean the inside of the rear window, remove the four Truss head bolts and fender washers. Wash with a mild soap or detergent using your bare hands to free or dislodge any caked-on dirt or other foreign particles. 3) Grease and oil may be removed with kerosene. 4) Novus I and Novus II are recommended plastic cleaners for acrylic units and can be used to remove light scratches. PLASTIC ROOF AND DOOR PANELS: 1) NEVER USE AN ABRASIVE DETERGENT/VEHICLE CLEANER OR A WIRE BRISTLED BRUSH. Do not use any CITRUS BASED CLEANERS such as orange or lemon. Use of these products will cause the plastic to become permanently damaged. 2) Clean the plastic surfaces thoroughly with warm soapy water and a COTTON cloth or chamois. Be sure to use mild soap, specifically a dish liquid or equivalent. Clean in a light circular motion for best results. 3) Remove grease and oil with mineral spirits and a COTTON cloth or chamois.
