Exclude danger and damage, check centre lock and battery retention, then interpret the exact model. On 3403/3404, one light flashing four times, eight times and a hot-pack indication are not interchangeable.

Release immediately; do not cycle a stalled drill. Isolate only after safe standstill. Restart preparation requires an identified corrected cause and restored tool/work conditions.

Inspect edges, flutes and gripping shank while isolated. Retire visible damage; investigate poor cutting conditions separately instead of extending a damaged bit’s life with pressure.

Inspect the shank and three-jaw contact with power isolated. Persistent abnormal motion with a sound correctly fitted accessory requires service, not a hand, ruler or probe near rotation.

Read both the flash timing and the sequence before and after insertion. Swelling, leakage or abnormal heating overrides normal lamp troubleshooting.

Remove the battery before reseating. If a sound, correctly fitted bit slips again, stop using the chuck.

Remove the battery and follow the release arrow with normal hand force. If the sleeve or jaws will not move normally, stop and arrange service.

Keep away from smoke, hissing or rapidly increasing heat; do not carry or remove the pack. Even without an active incident, stop work and do not treat a cool case as charging clearance.

Stop and isolate to check actual bit/recess fit, then direction, retention and clutch. A damaged recess or abnormal resistance is not cured by a higher setting.

Release and isolate only after a safe standstill. DS18DEX/DV18DEX rapid blinking groups overload and RFC; slower blinking indicates temperature protection. A cleared light does not clear the cause.

Stop fully before checking the selector. Stop using a switch that cannot move or hold position normally. A tight screw after selecting reverse does not establish switch failure.

First distinguish a missed connection from a shutdown accompanied by electrical damage. The external problems you can correct are limited; repeated starting does not clarify an unknown fault.

Small loops and hooked scratches are a reason to inspect the setup, not immediately reach for finer paper. Where the marks appear can help you decide what to check first.

A smooth-feeling board is not necessarily flat. Separate changes in shape from changes in colour or scratch pattern before sanding one patch again.

Use the last change to organise disconnected checks. Damage, severe symptoms and unexplained changes are not reasons for repeated restarts.

Record where dust appeared, then stop and inspect that component. A torn bag, unlatched lid and poor pickup beneath the pad are different problems, not reasons to tape every seam.

Do not add glue to a disc that lifts or has come off during use. Disconnect power and compare it with one new, correctly matched disc before replacing parts.

Do not keep fitting fresh discs and hoping. Match the tear, the disc condition before fitting and the work route to separate contact damage, damaged consumables and attachment problems.

A discoloured patch and a smoking housing, battery or collector need different responses. Stop safely before deciding which checks apply.

When dust suddenly increases, recall what changed last. New-disc holes, a lid refitted after emptying and a replacement hose connection deserve attention before blaming an internal fan.

A random-orbit pad is not a fixed-speed disc. Unfamiliar motion, vibration or stopping behaviour calls for taking it out of use, not pressing harder, touching the pad or sanding more wood to decide.

Address immediate danger, then keep the tool out of use and arrange the appropriate assessment and handling route.
