You must be familiar with your machine in order to understand the machine's capabilities. Also, before you operate your machine you must become familiar with the job site. If necessary, walk around the area and take note of the following items.
- Check the area for clearance. Check for both vertical clearance and for horizontal clearance.
- Check for the presence of overhead obstructions.
- Check for electrical power lines. Keep the machine and the attachments away from electrical power lines at least 8 m (25 ft).
- Check for steam lines. Check for compressed air lines.
- Check for changes in the stability of the surface of the job site. Check trenches that have been backfilled. Check deteriorated roofs of basements and of tunnels.
- Check sewers and service ducts.
When a load is picked up or when the boom is extended, ensure that the surface on the job site offers even resistance for the tires. Also, when a load is picked up or when the boom is extended, ensure that the surface on the job site offers even penetration for the stabilizers.

Make sure that the load charts and the instruction plates are in place and that the load charts and the instructions can be read. Do not operate the machine until you understand the correct method of using the load charts.
On machines that are equipped with a cab, secure the door in the shut position. Secure the windows in either the open position or in the shut position. Ensure that all windows are clean for the best visibility.
Inspect the condition of the seat belt and of the mounting hardware. Replace any parts that are worn or damaged. Regardless of appearance, replace the seat belt after three years of use. Do not use a seat belt extension on a retractable seat belt.
Make sure that all protective guards and covers are secured on the machine.
Adjust the seat so that full pedal travel can be achieved with the operator's back against the back of the seat.
Make sure that the machine is equipped with a lighting system that is adequate for the job conditions. Make sure that all of the machine lights are working properly.
Make sure that the machine horn, the backup alarm and all other warning devices are working properly.
Clear all obstacles from the path of the machine.
Before you attempt to start the engine and before you move the machine, ensure that no one is underneath the machine, around the machine, or on the machine. Make sure that the area is free of personnel. Fasten the seat belt.
Start the engine only from the operator compartment. Never short across the starter terminals or across the batteries. Shorting could damage the electrical system by bypassing the engine neutral start system.
