Safety - Section 22 OM2231
Page 22-4 Warnings and Cautions
A warning plate is attached to the frame above the
hydraulic system Auxiliary Power Unit (APU) quick
disconnect fittings. The plate alerts technicians that
high-pressure hydraulic oil is present during opera-
tion. Use caution when opening the hydraulic sys-
tem. There is a chance of residual pressure being
present. Loosen the fittings slowly to allow pressure
to dissipate before removing any connections.
Pressurized hydraulic fluid may penetrate the
skin. Serious injury and death may result if
proper medical treatment from a physician famil-
iar with this injury is not received immediately.
This plate is located on the battery box near the bat-
tery disconnect switches, and indicates that the bat-
tery system is a negative ground system.
These decals are placed above the battery discon-
nect switches on the right side of the front bumper to
indicate the OFF and ON positions of the switches.
Attached to the exterior of the battery compartment is
a danger plate. This plate stresses the prevention of
sparks near the battery. When another battery or
24VDC power source is used for auxiliary power, all
switches must be OFF prior to connecting. Maintain
correct polarity: connect the positive (+) posts
together and then connect the negative (-) lead of the
auxiliary power cable to a good frame ground. DO
NOT connect to the negative posts of the truck bat-
teries.
DO NOT connect near the battery box. These
precautions minimize the danger of sparks near the
batteries.
Sulfuric acid is corrosive, toxic, and explosive. Use
safety goggles, rubber gloves, and a rubber apron
when working near batteries.
If battery electrolyte is splashed into the eyes or is
ingested, get the proper medical attention immediately.
A warning instruction is located below the
and brake lock switches, which are located to the
right of the steering column on the instrument panel.
Pushing the top of the rocker-style switch turns the
function ON; pushing the bottom, turns it OFF.
