Symptoms

Rotation and impact pulses are steady, but a normal fastener advances much more slowly than expected.
The bit rotates, but no impact pulses begin when a correct fastener provides normal resistance.
The bit passed initial insertion, but backs out, falls free, or loses drive while the chuck body stays secure.
The bit rotates, but a real fastening load never produces the normal impact sound or pulses.
The accessory catches or stops in the material and the tool reacts sharply in the hand.
ट्रिगर वापस आता है और motor रुक जाता है, लेकिन LED लगभग 20 सेकंड से बहुत अधिक समय तक चालू रहता है।
The motor can be heard, but the front output remains still in both directions with the bit removed.
The motor runs normally, but the LED is dead, dim, or intermittent with trigger use.
The trigger returns normally and power drops, but the anvil repeatedly coasts instead of stopping promptly.
The tool works normally, but a fully charged pack empties much sooner on the same light task.
The accessory or fastener stops in the work and the tool stalls, twists, or cannot be withdrawn normally.
Spoušť se vrátí a napájení motor končí, ale sklíčidlo opakovaně setrvává mnohem déle než obvykle.
The charger shows charging or hot/cold delay, but the pack never reaches its normal charged indication.
The direction lever will not reach forward, reverse, or center lock, or the selected position does not hold.
The collar pulls, but the bit will not come out, or a short/broken piece is recessed in the chuck.
The direction button jams, will not hold center lock, or the tool runs in only one direction.
The quick-release collar is stuck, has limited travel, or does not spring back after it is pulled.
The trigger binds or does not spring fully OFF, or the motor keeps running after the trigger is released.
The trigger lights the work area, but the motor stays silent and the quick-release chuck does not turn.
A straight bit traces a visible circle at no load instead of rotating on a stable centerline.
