  • Page 10 Never exceed the maximum capacity of the trailer. By doing so you risk damage to your Demco trailer. If it’s ability to do a job, or to do so safely is in question DON’T TRY IT.
  • Page 11 Safety LOAD DISTRIBUTION SAFETY The total weight of the load you put on the trailer, plus the empty weight of the trailer itself, must not exceed the trailer’s Gross Vehicle Weight Rating (GVWR). You must distribute the load on the trailer such that the load on any tire or axle does not exceed the tire load rating or the Gross Axle Weight Rating (GAWR).
  • Page 12 BOLT TORQUE, TORQUE DATA FOR STANDARD NUTS, BOLTS, AND CAPSCREWS. Tighten all bolts to torques specified in chart unless otherwise noted. Check tightness of bolts periodically, using bolt chart as guide. Replace hardware with same grade bolt. NOTE: Unless otherwise specified, high-strength Grade 5 hex bolts are used throughout assembly of equipment.

  • Page 13: Torque Requirements

    TORQUE REQUIREMENTS It is extremely important to apply and maintain proper wheel mounting torque on your trailer axle. Torque is a measure of the amount of tightening applied to a fastener (nut or bolt) and is expressed as length times force. For example, a force of 90 pounds applied at the end of a wrench one foot long will yield 90 lbs-ft of torque.
  • Page 14 Safety/Decal/Reflectors Important: Install new safety decals and reflectors if the old decals and reflectors are destroyed, lost, painted over or cannot be read. When parts are replaced that have decals or reflectors, make sure you install a new decal with each new part. AP4495 AP2914 AP4292...

  • Page 15: Safety Decals

    Safety/Decal/Reflectors HOW TO APPLY SAFETY DECALS: Be sure that the installation area is clean and dry. Be sure temperature is above 50°F(10°C).

  • Page 27: Full Function Anti-Lock Brake System

    Full Function Anti-lock Brake System GENERAL OPERATION OF THE ABS SYSTEM The Full Function Anti-lock Brake System (FFABS) maintains stability and control during braking by preventing wheel lock-up. FFABS consists of Sensors and Exciters, Modulating Relay Valve, and an Electronic Control Unit (ECU) to maximize the braking ability of the trailer.
  • Page 28 The Full Function ABS System The Full Function ABS Valve was designed as a method of providing a complete trailer braking system combined with skid control in a single package. This valve combines the functions of several separate valves while providing all the valve needs for trailer service and spring brakes.

  • Page 36: Adjustment And Operation Of Brakes

    Adjustment and Operation of Brakes CARE AND ADJUSTMENT OF BRAKES The trailer brake system will perform safely and efficiently only as long as you maintain it properly and do not abuse it. Trailer brakes should be inspected and adjusted frequently in connection with a Trailer Preventative Maintenance program. Out-of- adjustment brakes can cause increased stopping distance, shorter brake component life, and a greater tendency for the trailer to jackknife.
  • Page 37 Adjustment and Operation of Brakes WARNING: Do not operate this vehicle with any brake defects or with brakes out of adjustment. CHECK BRAKE OPERATION Before entering traffic, check the operation of the trailer brakes to be sure they are in good working order. Try foot pedal, emergency dash control valve (push, pull or flip), and trailer brake lines to assure brake application and release in each instance.

  • Page 38: Tires

    The total load per tire must not exceed the tire manufacturer’s specified load carrying capacity at stated inflation pressures for both tires and rims. Demco Side Dump trailers, as required by the certification regulations of the National Highway Traffic Safety Administration (CFR 49, Part 567), has a Gross Axle Weight Rating plate on each trailer for your information on the running gear capacity.
