SAFETY MEASURES DURING MAINTENANCE STORING TIRES Basically, tires must be stored in a protected room that can- not be accessed by unauthorized persons. Place the tires on an even surface and incline them 60° to 70° (2) against a solid stopper. Secure the tires with wheel chocks (1) so that they cannot roll away, tip over, or slip. If, however, a tire tips over despite this safety measure, do not try to stop it, but get out of the way as quickly as possi- ble, since tires for construction machines are very heavy and may cause serious injuries. 3-30
