How can I fix my Bosch hammerdrill. is this model 'worth being fixed'?

Bosch hammerdrill model 0 601 194 639 which I've owned for 2 1/2 years but only lightly used till last night, when i was putting some holes in a foundation wall abruptly stopped turning as if some gears had stripped or something. Is this tool not really as good as the reputation for Bosch has traditionally been? Is it worth me fixing it? Or, is it going to be a 'red Herring"? If it's not 'under built' like all Black andDecker junk is then, is it something I can get a 'fix it' manual for, and procure the parts for? Appreciate any info you could provide me with. Thanks, and happy Mothers day to you and yours. mike grane
