Warnings and Cautions
The Warning on the right specifies that if any of the red
lights on the instrument panel are "ON" (during truck
operation), the truck should not be operated.
The switch in this panel is a manual test switch to check
all indicator lights for operation.

This decal on the R.H. instrument panel warns the
operator that the transmission will upshift automatically
if engine overspeeds. Apply brakes to slow down.
If the Engine Overspeed Warning Light illuminates and
the warning buzzer sounds, the operator MUST take
some action to reduce the engine speed BELOW 2350
RPM. i.e. Remove foot from accelerator, and apply the
retarder (and/or service brakes, if necessary) to slow
the vehicle down. See Section 3, Operaton for details.

This decal is applied to the right side cab window to
identify the various symbols that are on the instrument
panel or gauges. Refer to "Operator and Instrument
Controls", for function/control identified by symbol.

WA9702 decal is located on the battery box cover. The
battery box is mounted on the right deck structure. This
decal informs the technician that the truck electrical
system is Negative Ground.
If batteries are removed, proper polarity must be main-
tained at installation. Always disconnect ground last.
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.
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-
o
o
o
tween 160
- 190
F (71
- 88
coolant may be expelled from the radiator resulting in
serious scalding and burning if pressure is not released
prior to removal of cap.
