OM2017.2 Safety - Section 2 Warnings and Cautions Page 2-19 WARNINGS AND CAUTIONS The following paragraphs give an explanation of the Warning, Caution, and Service Instruction plates and decals attached to the truck. The plates and decals listed are typical of this model, but because of customer options, individual trucks may have plates and decals that are different from those shown here. The plates and/or decals must be kept clean and legible. If any decal and/or plate becomes damaged or unable to be read, it should be replaced with a new one. A warning plate is mounted around the key switch on the instrument panel.
The warning stresses the importance of reading the operator’s manual before operation. A warning is mounted on top of the instrument panel above the voltmeter. This decal warns operator that operating truck (engine running) with less than 26 volts may result in a loss of dynamic retarding. A warning plate is mounted directly under the red warning lights in the center of the instrument panel. The plate warns that TRUCK SHOULD NOT BE OP- ERATED WITH ANY RED WARNING LIGHTS ON. If any of the red warning lights are on, the truck should be safely stopped, engine shut down, and main- tenence notified.
A Warning plate is mounted on the instrument panel around the " Dry/Slippery Road " switch and the Wheel Brake Lock switch. The " Dry/Slippery Road " switch on the instrument panel warns that the slippery road position reduces front wheel braking effort while maintaining full braking of the rear wheels. Reduced braking of the front wheels assists in steering control on slippery roads, but in- creases stopping distance. The Dry/Slippery road con- trol switch permits the operator to select either full braking capability at all wheels for "dry" road or re- duced braking at the front wheels for "slippery" road.
The Wheel Brake Lock should be used (with engine running) ONLY at the dump and loading operations. The Wheel Brake Lock applies pressure to the REAR WHEEL BRAKES ONLY. Front wheel brakes are NOT applied. DO NOT use for stopping or for parking truck with engine shut down. With engine shut down, pres- sure will bleed down, and service brakes will NOT hold truck if parking brake is not applied.
