Electrical System Hazards

1-4
The hydraulic system is under pressure whenever the engine is running
and can hold pressure after the engine is shut down. After forks or
attachments are resting on the ground or support, make sure pressure is
relieved from all hydraulic lines and components before removing them
from the circuit.
Remember the following during inspection of the hydraulic system:
• Wait for fluid to cool down before disconnecting lines.
• DO NOT use your hand to check for leaks. Use a piece of cardboard or
paper to search for leaks.
• Wear appropriate eye protection.
• If any hydraulic fluid is injected into the skin, get medical attention
immediately.
• When venting or filling the hydraulic system, loosen the filler cap slowly
and remove it gradually.
• NEVER reset any relief valve in the hydraulic system to a pressure
higher than that specified in this manual.
Be aware of the following safety issues when working with batteries.
Explosive gases are always present around batteries. This is especially
true when the battery is being charged.
To avoid explosion...
• DO NOT use smoking materials near batteries.
• Keep arcs, sparks, and open flames away from batteries.
• Provide adequate ventilation.
