TROUBLESHOOTING
Cause
Not connected to compressed air
Rotor rusty due to humidity
Vanes jam (worn out)
Gear blocks
Impurities in the valve
Too little operating pressure Hose
diameter too small
Too little volume flow
Rotor is rubbing against the end plate /
cylinder bushing
Gear parts are worn down
Cause
Vanes are worn or broken;
broken parts are jammed between the
rotor and the cylinder bushing
No lubrication – ball bearings were
running dry; rotor was rubbing against
the end plates
Coarse dirt particles in the motor
compartment between the rotor and the
cylinder bushing
Needle cages are defective Gear
teeth are chattering Ball bearings are
defective
Drill chuck defective
Diameter of drill bit too small
Dirt in reversing area
Bearing needles jam
Remedy
Connect and open the supply line
Disassemble motor and clean it Check
functioning of maintenance unit
Disassemble motor and clean it,
replace worn out parts
