1. Failure phenomenon: After power-on, click to operate normally, without impact, or with little impact
Cause analysis/exclusion method:
1. The head assembly of the impact drill is faulty/the head assembly is not clean and there are impurities. After wiping clean, drip a few drops of good engine oil (thin) or salad oil, connecting rods, pistons, aprons on the hammer Or the imported ring has worn out and replace it
2, the crankshaft breaks/changes the crankshaft
3, the large teeth on the crankshaft wear/replace the large teeth on the crankshaft
4, rotor teeth wear/change the rotor
2. Failure phenomenon: no response after power on
Cause analysis/exclusion method:
1. The switch or wire is broken/replace the switch or wire
2. The stator or rotor is burnt/replace the stator or rotor
3. The stator pull ring is burnt/replace the pull ring
4, carbon brush wear / change carbon brush
3. Failure phenomenon: After power-on, there is no noise and hammering, but the rotor sparks big
Cause analysis/exclusion method:
1. Carbon brush wear/change carbon brush
2. The brush holder is loose/fixed and the brush holder is replaced.
