Ultra-Low Sulfur Diesel (ULSD) Hazard
WARNING!
Ultra-Low Sulfur Diesel (ULSD) poses a
greater static ignition hazard than earlier diesel
formulations with higher sulfur content. Avoid death or
serious injury from fire or explosion;
consult with your
fuel or fuel system supplier to ensure the delivery
system is in compliance with fueling standards for
proper grounding and bonding practices.
Engine Coolant Hazards
WARNING!
Avoid serious injury or death. Liquid
cooling systems build up pressure as the engine gets
hot, so
use extreme caution before removing the
radiator cap.
• Stop the engine and wait for the system to cool
• Wear protective clothing and safety glasses
• Turn the radiator cap slowly to the first stop to allow
the pressure to escape before removing completely
Hydraulic System Hazards
Be sure to follow manufacturer’s instructions for relieving
fluid pressure before performing any maintenance. The
hydraulic system is pressurized whenever the engine is
on and may hold pressure even after the engine is shut
off. Cycle hydraulic controls, including auxiliary hydraulic
control (if equipped), after the engine is shut off.
During inspection of the hydraulic system:
• Wait for fluid to cool before disconnecting the lines
Hot hydraulic fluid can cause
severe burns
• Wear appropriate eye protection. Hydraulic fluid can
cause permanent eye injury
• When venting or filling the hydraulic system, loosen
the filler cap slowly and remove it gradually
•
Never
reset any relief valve in the hydraulic system
to a pressure higher than recommended by the
manufacturer

Hydraulic Fluid Injection Hazard
WARNING!
Accidental injection of high-pressure
fluid into the hands or body is dangerous and could
result in death or serious injury.
Use caution when
checking hydraulic leaks as pressurized hydraulic
fluid has enough force to penetrate skin, causing
serious personal injury.
If a leak is discovered:
• Ensure engine is turned off; relieve pressure in
hydraulic circuit
• Wear proper hand and eye protection
• Visually examine the hydraulic hoses or fluid lines in
the vicinity of the leak for breaks or cracks.
Do not
use your hand to check for leaks
• Repair or replace hydraulic lines according to the
manufacturer’s recommendations
Fluid injection injuries are not always obvious. Victims
have reported such injuries feel like a bee sting or
splinter under the skin. If you suspect you have a fluid
injection injury, do not take chances. Seek proper
medical care immediately. If any fluid is injected into the
skin, it must be surgically removed within a few hours by
a doctor familiar with this type of injury.
