9. INTRODUCTION
Personal safety
General safety rules
Use caution when operating the machine on slopes. Raised equipment, full tanks and other loads will change the
center of gravity of the machine. The machine can tip or roll over when near ditches and embankments or uneven
surfaces.
Never permit anyone other than the operator to ride on the machine.
Never operate the machine under the influence of alcohol, drugs, or while otherwise impaired.
When digging or using ground engaging attachments be aware of buried cables. Contact local utilities to determine
the locations of services.
Pay attention to overhead power lines and hanging obstacles. High voltage lines may require significant clearance
for safety.
Hydraulic oil or diesel fuel leaking under pressure can penetrate the skin, causing serious injury or infection.
• DO NOT use your hand to check for leaks. Use a piece of cardboard or paper.
• Stop engine, remove key and relieve the pressure before connecting or disconnecting fluid lines.
• Make sure all components are in good condition and tighten all connections before starting the engine or pressur-
izing the system.
• If hydraulic fluid or diesel fuel penetrates the skin, seek medical attention immediately.
• Continuous long term contact with hydraulic fluid may cause skin cancer. Avoid long term contact and wash the
skin promptly with soap and water.
Keep clear of moving parts. Loose clothing, jewelry, watches, long hair, and other loose or hanging items can become
entangled in moving parts.
Wear protective equipment when appropriate.
DO NOT attempt to remove material from any part of the machine while it is being operated or components are in
motion.
Make sure all guards and shields are in good condition and properly installed before operating the machine. Never
operate the machine with shields removed. Always close access doors or panels before operating the machine.
Dirty or slippery steps, ladders, walkways, and platforms can cause falls. Make sure these surfaces remain clean and
clear of debris.
A person or pet within the operating area of a machine can be struck or crushed by the machine or its equipment. DO
NOT allow anyone to enter the work area.
Raised equipment and/or loads can fall unexpectedly and crush persons underneath. Never allow anyone to enter
the area underneath raised equipment during operation.
Never operate engine in enclosed spaces as harmful exhaust gases may build up.
Before starting the machine, be sure that all controls are in neutral or park lock position.
Start the engine only from the operator’s seat. If the safety start switch is bypassed, the engine can start with the
transmission in gear. Do not connect or short across terminals on the starter solenoid. Attach jumper cables as
described in the manual. Starting in gear may cause death or serious injury.
Always keep windows, mirrors, all lighting, and Slow Moving Vehicle (SMV) emblem clean to provide the best possible
visibility while operating the machine.
Operate controls only when seated in the operator’s seat, except for those controls expressly intended for use from
other locations.
