General Safety Instructions

Important Safety Notice
Improper practices, carelessness, or ignoring the warnings
can cause burns, cuts, mutilation, asphyxiation or other
personal injury or death.
Read and understand all of the safety precautions and warnings
before performing any repair. This list contains the general
safety precautions that must be followed to provide personal
safety. Special safety precautions are included in the
procedures when they apply.
• Work in an area surrounding the product that is dry,
well lit, ventilated, free from clutter, loose tools, parts,
ignition sources and hazardous substances. Be
aware of hazardous conditions that can exist.
• Always wear protective glasses and protective shoes
when working.
• Rotating parts can cause cuts, mutilation
strangulation.
• Do not wear loose-fitting or torn clothing. Remove all
jewelry when working.
• Disconnect the battery (negative [-] cable first) and
discharge any capacitors before beginning any repair
work.
Disconnect the air starting motor if equipped to
prevent accidental engine starting. Put a "Do Not
Operate" tag in the operator's compartment or on the
controls.
• Use ONLY the proper engine barring techniques for
manually rotating the engine. Do not attempt to rotate
the crankshaft by pulling or prying on the fan. This
practice can cause serious personal injury, property
damage, or damage to the fan blade(s) causing
premature fan failure.
• If an engine has been operating and the coolant is hot,
allow the engine to cool before slowly loosening the fill
cap to relieve the pressure from the cooling system.
• Always use blocks or proper stands to support the
product before performing any service work. Do not
work on anything that is supported ONLY by lifting
jacks or a hoist.
• Relieve all pressure in the air, oil, fuel, and cooling
systems before any lines, fittings, or related items are
removed or disconnected. Be alert for possible
pressure when disconnecting any device from a
system that utilizes pressure. Do not check for
pressure leaks with your hand. High-pressure oil or
fuel can cause personal injury.
