OM2005.2 10/96 Safety - Section 2 Warnings and Cautions Page 2-7 The center Warning specifies that if any of the red lights on the instrument panel are "ON" (during truck opera- tion), the truck should not be operated. The switch in this panel is a manual test switch to check all indicator lights for operation. Attached to the exterior of the battery compartment is danger plate WA9704. This plate stresses the need to keep from making any sparks near the battery. When getting a battery assist from one truck to another, all switches must be "Off" prior to making any connec- tions. Be certain to maintain correct polarity.
Connect one lead of booster cable to 24V positive (+ ) post of battery needing assist, and other lead of the booster cable to the 24V positive (+ ) post of auxiliary battery. Connect one lead of second booster cable to 24V negative (-) post of auxiliary battery and then connect other lead of the booster cable to a good frame ground on the disabled truck away from the battery needing assist. This procedure will avoid the possibility of caus- ing sparks near the battery where explosive gases may be present. The Warning on the right specifies that when the slip- pery road control is in use, braking power to the front wheels is reduced.
The Slippery Road switch will not be present on Haulpak ® Trucks with rear oil-cooled disc brakes. . . . . . . . . . . . . . . . . . . . . . . . . . . . . WA6488 instruction decal is applied to the right side window of the cab. It identifies the various symbols that may appear on the instrument panel and gauges. Refer to Operator and Instrument Controls, for description of function or control being identified by symbol. Sulfuric acid is corrosive and toxic. Use proper safety gear, goggles, rubber gloves and rubber apron when handling and servicing batteries. . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Warning plate WA9707 is mounted on top of the radia- tor grille near the radiator cap. Radiator pressure must be released (refer to Radiator, Section "C"), before removing the radiator cap after engine has been running. The engine cooling system is controlled by thermostats which keep coolant temperature be- tween 160 o - 190 o F (71 o - 88 o C) during operation. Hot coolant may be expelled from the radiator resulting in serious scalding and burning if pressure is not released prior to removal of cap. . . . . . . . . . . . . . . . . . . . . . . . . . . . . WA9702 decal is located on top of the battery box cover. The battery box is mounted on top of the right deck structure.
This decal informs the technician that the truck electrical system is Negative Ground . If the batteries are removed, proper polarity must be main- tained at installation. Always disconnect ground last. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
