Hydraulic Fluid Injection Hazard
WARNING! Accidental injection of high-pressure oil
into the hands or body is dangerous and could result in
death or serious injury. Use caution when checking
hydraulic leaks as pressurized hydraulic uid has
enough force to penetrate skin, causing serious
personal injury.
If you discover a leak:
• Ensure engine is turned off; relieve pressure in
hydraulic circuit.
• Wear proper hand and eye protection.
• Visually examine the hydraulic hoses or uid 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 uid
injection injury, do not take chances. Seek proper
medical care immediately. If any uid is injected into the
skin, it must be surgically removed within a few hours by
a doctor familiar with this type of injury.
Diesel Particulate Filter Hazard
You may need to run an active regeneration on some
machines with a diesel particulate lter (DPF). Running
an active regeneration to clean a DPF can create
extremely high temperatures. Consult your operator’s
manual for the proper procedure for running an active
regeneration.
WARNING! Extremely high temperatures can cause a
re or explosion, so do not run an active regeneration
in an explosive or ammable atmosphere.

Do not operate in

Electrical System Hazards
Light Bulbs and Illumination
Some machines are equipped with High-Intensity
Discharge (HID) Xenon light bulbs which operate at very
high voltage. Do not begin installation of HID-Xenon
lamps unless the lamps are turned off, the engine is
turned off, the key is removed (if equipped), and you are
wearing appropriate eye protection.
WARNING! Do not look directly into HID-Xenon
lamps. Eye damage could occur.
Wear gloves and safety glasses when handling bulbs.
Dangerous voltage sparks may occur and cause injury
or damage to the connector. See manufacturer’s
warnings packaged with replacement bulbs.
Before working on the electrical system, either hit
the main power disconnect switch, if equipped, or
disconnect the battery cable(s).
• Remove the battery negative (–) cable(s) rst.
• When reconnecting the battery, connect the battery
negative (–) cable(s) last.
Battery Hazards
The liquid in batteries contains acid, which is a POISON
and could cause SEVERE CHEMICAL BURNS.
Avoid injury:
• Wear a face shield to prevent contact with your eyes.
• Wear chemical-resistant gloves and clothing to keep
liquid off your skin and regular clothing.
WARNING! Liquids in batteries will damage eyes or
skin on contact. Always wear a face shield to avoid
getting liquid in your eyes.
If liquid from the battery contacts your eyes, ush
immediately with clean water and get medical attention.
Wear chemical-resistant gloves and protective clothing
to keep liquid off your skin. If liquid contacts skin or
clothing, wash off immediately with clean water. If liquid is
ingested, drink large quantities of water or milk. DO NOT
induce vomiting. Seek medical attention immediately.
