Fluid Spillage Containment
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting and
repair of the machine. Be prepared to collect the fluid with
suitable containers before opening any compartment or
disassembling any component containing fluids. Refer to
"Tools And Shop Products Guide", NENG2500 for tools and
supplies suitable to collect and contain fluids in Caterpillar
machines. Dispose of fluids according to local regulations and
mandates.

NOTICE
Do not pry on the injector hold down bracket. Damage to
the injector could occur. The injector has a notch in it on
the side opposite the rack. This notch is used for prying
the injector loose. Also, some injector racks may move
freely when the spring is not compressed, however, do not
move the unit injector rack without the injector spring
slightly compressed. Damage to the injector could occur.
