Maintenance
• Only trained and authorized personnel, with a full awareness of safe procedures,
should be allowed to operate or perform maintenance or service on the machine.
• Use warning tag/control lockout procedures during service. Alert others that service or
maintenance is in progress by tagging the operator’s controls — and other machine
areas if required — with a warning notice.
• Never attempt to bypass the ignition keyswitch to start the engine. Use only the jump-
starting procedure described in this manual. See “Jump-starting” on page 90.
• Never use your hands to search for hydraulic fluid leaks. Instead, use a piece of paper
or cardboard. Escaping fluid under pressure can be invisible and can penetrate the skin
and cause serious injury. If any fluid is injected into your skin, see a doctor at once.
Injected fluid must be surgically removed by a doctor or gangrene may result.
• Do not attempt to loosen or disconnect any hydraulic lines, hoses, fittings, covers or
caps without first relieving hydraulic circuit pressure. Relieve hydraulic pressure by
performing the “Mandatory Safety Shutdown Procedure” on page 16 and slowly loos-
ening the hydraulic reservoir filler cap. Be careful not to touch any hydraulic compo-
nents that have been in recent operation. Failure to heed this warning could result in
severe burns.
• Do not attempt to remove the radiator cap after the engine has reached operating tem-
perature or if it is overheated. At operating temperatures, engine coolant is extremely
hot and under pressure. Always wait for the engine to cool before attempting to relieve
pressure and remove the radiator cap. Failure to heed this warning could result in
severe burns.
• Do not work on hot engines, cooling systems or hydraulic systems. Wait for the engine
to cool. When engine lube oil, gearbox lubricant or other fluids require changing, wait
for fluid temperatures to decrease to a moderate level before removing drain plugs.
Note: Temperatures below 49°C (120°F) will reduce the chances of scalding
exposed skin while allowing the fluid to drain quickly and completely. Do not let
the fluid fully cool, because drain time will be substantially increased.
• Do not run the engine if repairs are being performed alone. There should always be at
least 2 people present if the engine must be run during service. Both persons must
maintain visual contact with each other. Keep a safe distance away from all rotating
and moving parts.
• Always wear safety glasses with side shields when striking metal against metal. In
addition, it is recommended that a softer (chip-resistant) material be used to cushion
the blow. Flying metal debris can cause serious injury to the eyes or other parts of the
body.
• If the lift arm is raised, do not allow anyone underneath it and/or do not exit the
machine unless the lift arm support is properly applied. See “Lift Arm Support” on
page 44. Disconnecting or loosening any hydraulic line, hose, fitting or component,
parts failure, and venting hydraulic pressure all can cause the lift arm to drop.
