Engine Starting
If a warning tag is attached to the engine start switch or to the controls, do not start the engine. Also, do not move any controls. Make sure that you are seated before you start the engine.
Move all hydraulic controls to the HOLD position and ensure that the hydraulic lockout control is in the LOCKED position before you start the engine. Refer to Operation and Maintenance Manual, "Hydraulic Lockout Control".
Engage the parking brake.
Note: Turn the key to the ON position in order to activate the monitor and check the status of the parking brake.
Diesel engine exhaust contains products of combustion which can be harmful to your health. Always run the engine in a well ventilated area. If you are in an enclosed area, vent the exhaust to the outside.
Briefly sound the horn before you start the engine.
