Safety
Before moving the machine to the work site, check to ensure that all doors, panels, and access covers are installed properly and secured. CAB EXITS There are 2 ways to exit the cab in case of an emergency. 1. Side Door – This is the main point of entry used under normal operating conditions to enter or leave the cab. This door is not equipped with a safety interlock switch and therefore when left open will not deactivate the pilot controls in the cab. The left armrest is equipped with a safety interlock switch that prevents machine operation when the armrest is raised. See SAFETY INTERLOCK SWITCH ON LEFT ARMREST for more details. ALWAYS shut OFF engine before using the side door exit. 2. Side Window – This is a second cab exit for use if the side door exit becomes blocked. This window is not equipped with a safety interlock switch and therefore when left open will not deactivate the pilot controls in the cab. ALWAYS shut OFF engine before using the side window as an escape hatch exit. It is important that the operator of the machine be familiar with these emergency exits and how to use them. All operators should practice using all the cab exits to become familiar with escape procedures should they need to perform them in the dark, when the machine is in a rolled position, or other possible adverse condition. The exits should be checked to make sure that they are operational and will function in an emergency. For additional information, refer to EMERGENCY EXITS in SECTION 2.
SAFETY INTERLOCK SWITCH ON LEFT ARMREST The left arm rest is equipped with a safety interlock switch (1) to prevent the machine from being operated while the armrest is in the raised position (pilot system is shut off). NOTE: The engine can be started but the machine functions cannot be operated with the left arm rest up. ARMREST

PILOT SYSTEM SHUT OFF
To operate: 1. With the engine running and the left arm rest DOWN, push the pilot reset switch. 2. Once the safety interlock system has been activated, the safety of both the operator and all persons outside the cab becomes the responsibility of the operator. 3. The left arm rest safety interlock switch (pilot system shut off limit switch) and the pilot reset switch are a safety feature and their function must not be defeated in any way. 4. When the engine is running, DO NOT allow anyone in areas of the machine where they may be crushed by moving components.
WARNING
5. Maintain a safe operating distance between the machine and other personnel. Never operate the boom or attachment over the heads of bystanders.
