Safety Precautions General
– 3 –
steering lock or its wiring. Under no cir-
cumstances must the ignition switch be
separated from the steering lock.
Oils and Lubricants
Many liquids and other substances
used in commercial vehicles are highly
toxic. These must not be consumed or
inhaled and, as far as possible, must be
kept from skin contact. These sub-
stances, amongst others, include bat-
tery acid, anti-freeze, hydraulic fluid,
lubricants, fuel, windshield washer fluid,
refrigerant, and various adhesives.
Avoid unnecessary contact with used
engine oil. Prolonged and repeated
contact with used engine oil may cause
serious skin disorders.
Extreme care must be taken when
draining engine oil; hot engine oil can
cause severe personal injury.
Maintenance Activities
Do not use the jack as the sole means
of support; position suitable supports
beneath the chassis frame.
Do not attempt to work on the vehicle
with the cab partially tilted.
Do not attempt to stand on the cab roof.
Chassis Frame
Do not weld or subject the chassis
frame to a severe localized heat source.
Failure to observe this precaution may
result in irreparable damage to the
material structure of the chassis frame
with consequent loss in chassis frame
strength.
Welding or drilling on the chassis frame
must not be undertaken without the
prior written consent of PACCAR Inc.
Unauthorized, indiscriminate welding or
drilling may adversely affect the safe
load-carrying characteristics of the
chassis frame.
Welding
• Observe these recommended pro-
cedures to protect electronic sys-
tems during welding operations.
All Electronic Engines
Before welding on vehicles equipped
with electronic engines, the following
precautions should be observed:
NOTE: Welding to frame rail
may void frame rail warranty.
• Turn engine OFF.
• Disconnect all electronic connec-
tions to the vehicle batteries.
• Remove battery power cable and
insulate it from the vehicle.
