WASHINGTON (AP) _ The manufacturer of the Hedstrom Probe VI battery-powered riding toy has offered to repair the devices to eliminate a potential fire hazard, the Consumer Product Safety Commission announced Wednesday.

Eight instances have been reported in which the toys have caught fire, one resulting in a serious blaze in a mobile home, the commission said. The fires can occur both while the toy is being ridden and while it is being stored, the commission said.

The Probe VI is a six-wheeled, two-speed, all-terrain vehicle with two motors powered by six-volt, gel-type lead acid batteries. It is designed for children age 3 to 7.

According to the safety commission, the fire danger exists in units without fuses, about 30,000 of which were manufactured from 1983 to June 1985. They were sold nationwide.

The affected units can be identified by the model identification label on the front underside of the plastic body. Models involved in the repair program are 67-3890, 67-3891, 67-3892, 67-38921, 67-3893 and 67-38931 with dates of manufacture prior to June 1985. After that date, the company began using fuses in the wiring system.

Hedstrom Corp. is offering a fuse protection kit at no charge to owners of the affected toys. Until the kit is installed, the toy should not be used and the batteries should be removed, officials said.

To obtain the kit, Probe VI owners should call Hedstrom at 1-800-233-3271. Pennsylvania residents should call 1-800-242-9034. Owners also can write to Hedstrom Corp., Dept. 100, P.O. Box 432, Bedford, Pa., 15522-0432.
