WARNING
Avoid injury!
Shut off the engine, remove the key, and make sure all machine motion stops before you service the
machine.
Failure to comply could result in death or serious injury.
W1128B
WARNING
Chemical hazard!
Use caution when opening the quick coupler cap from the load port. There may be product left in the
port.
Failure to comply could result in death or serious injury.
W1039A
WARNING
Crushing hazard!
The lifting systems must be operated by qualified personnel who are aware of the correct procedures
to follow. Make sure all lifting equipment is in good condition, and all hooks are equipped with safety
latches.
Failure to comply could result in death or serious injury.
W0256A
WARNING
Heavy objects!
Lift and handle all heavy components using lifting equipment with adequate capacity. Always support
units or parts with suitable slings or hooks. Make sure the work area is clear of all bystanders.
Failure to comply could result in death or serious injury.
W0398A
WARNING
Burn hazard!
Before performing any service on the hydraulic system, you must allow it to cool. Hydraulic fluid
temperature should not exceed 40 °C (104 °F).
Failure to comply could result in death or serious injury.
W0241A
WARNING
Escaping fluid!
Hydraulic fluid or diesel fuel leaking under pressure can penetrate the skin and cause infection or
other injury. To prevent personal injury: Relieve all pressure before disconnecting fluid lines or per-
forming work on the hydraulic system. Before applying pressure, make sure all connections are tight
and all components are in good condition. Never use your hand to check for suspected leaks under
pressure. Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your
doctor immediately.
Failure to comply could result in death or serious injury.
W0178A
WARNING
Chemical hazard!
When handling fuel, lubricants, and other service chemicals, follow the manufacturer's instructions.

  • 20. Engine - Engine and crankcase Engine - Remove WARNING Avoid injury! Shut off the engine, remove the key, and make sure all machine motion stops before you service the machine. Failure to comply could result in death or serious injury. W1128B WARNING Chemical hazard! Use caution when opening the quick coupler cap from the load port. There may be product left in the port. Failure to comply could result in death or serious injury. W1039A WARNING Crushing hazard! The lifting systems must be operated by qualified personnel who are aware of the correct procedures to follow. Make sure all lifting equipment is in good condition, and all hooks are equipped with safety latches. Failure to comply could result in death or serious injury. W0256A WARNING Heavy objects! Lift and handle all heavy components using lifting equipment with adequate capacity. Always support units or parts with suitable slings or hooks. Make sure the work area is clear of all bystanders. Failure to comply could result in death or serious injury. W0398A WARNING Burn hazard! Before performing any service on the hydraulic system, you must allow it to cool. Hydraulic fluid temperature should not exceed 40 °C (104 °F). Failure to comply could result in death or serious injury. W0241A WARNING Escaping fluid! Hydraulic fluid or diesel fuel leaking under pressure can penetrate the skin and cause infection or other injury. To prevent personal injury: Relieve all pressure before disconnecting fluid lines or per- forming work on the hydraulic system. Before applying pressure, make sure all connections are tight and all components are in good condition. Never use your hand to check for suspected leaks under pressure. Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your doctor immediately. Failure to comply could result in death or serious injury. W0178A WARNING Chemical hazard! When handling fuel, lubricants, and other service chemicals, follow the manufacturer's instructions. Wear Personal Protective Equipment (PPE) as instructed. Do not smoke or use open flame. Collect fluids in proper containers. Obey all local and environmental regulations when disposing of chemi- cals. Failure to comply could result in death or serious injury.
