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.
At operating temperature, the engine coolant is hot and
under pressure. Steam can cause personal injury. Check
the coolant level only after the engine has been stopped
and the fill cap is cool enough to touch with your bare
hand. Remove the fill cap slowly to relieve pressure in the
cooling system. Cooling system conditioner contains
alkali. Avoid contact with skin and eyes to prevent
personal injury.
