My hitachi jackhammer runs slow and gets hot
The armature AND electric field must together replaced to get a safe working again, and the defect will not repeat if it be shure have its operating hours on it and give a full service.

It sounds like the gearbox oil is getting low. The GBH5 uses oil in the gearbox, not a grease - the grease is used for assembly only. The correct type is a PG-150 (fully synthetic gear oil). Unable to find it in small quantities, I now use PAG150 oil for automotive a/c systems, it's available in small bottles. As for quantity, no-one seems to know... I just fill to cover the big bottom gears.

Check your brushes. The brushes on the Brute breaker have a spring loaded, non-conductive pin in them. When either brush wears down far enough the pin pops out and prevents damage to the expensive armature. If by chance the brushes are OK you may have to have your armature tested.
