guys I haven't used my warthog in over three years. now since I bought another trailor jetter I need it to work properly. the new jetter is just 2000psi at 12gpm..which is enough to cut out most residential roots but I guess since its been not in use for so long its frozen. I already oiled it with the lube oil but still wont spin. Any ideas?comments?..can I mail it to somewhere to get fixed?..let me kno...thanks.
