Usage and Care Tips
Position the safe on a hard, level floor and leave enough clearance in front for the 250° door swing. Remove the wheels once it is in its final place. Remember that the panel locks after wrong entries, so keep your code and the key in separate secure places away from the safe. Wipe the steel body with a damp cloth and operate the handle and lock without force for a long, trouble-free service life.
