Torque driver

If you have a torque driver, refer to the “Torque” column for each step.

• Make sure that you use the correct screw. If you have a torque screwdriver, tighten all screws firmly to the

torque shown in the table. Never use a screw that you removed. Use a new one. Make sure that all
of the screws are tightened firmly.

• Ensure torque screw drivers are calibrated correctly following country specifications.
