Regional instructions: My SV10 label and US manual 229602-01 match Use your supplied regional manual if it differs; do not infer compatibility from a similar name. PREPARE [ ] Read SV10 on the label, confirm the US 229602-01 manual and match the pinch-handle Filter A, twist-off Filter B and any head involved. [ ] Disconnect the charger, release the trigger and let the machine cool before handling removable parts. Keep your hand away from the trigger.

CONSUMABLE FIT Existing Dyson-specified charger: Match the charger to the exact machine through Dyson support; no universal voltage or part number is inferred. Fit: US SV10 machine and its specified charger Do not substitute: Damaged, substitute or modified chargers; opening or probing a charger Source: dyson-v8-manual, p11 Diagnostics – lights during charging; p12 Charging and storage; Battery safety instructions CHECK ROUTE safety: Is the charger disconnected, the machine cool and undamaged, and your hand away from the trigger? Yes -> check-1: Continue with the matching parts and the checks below. No -> service: Stop for a damaged charger, burning smell, liquid exposure, a swollen or leaking battery, broken catches or an obstruction you cannot safely reach. Contact Dyson and keep the battery sealed. Not sure -> prepared: Save your observations and compare the matching manual before continuing. check-1: Was the observed light on the machine during use, with the charger disconnected? Yes -> check-2: Use the during-use meanings below. No -> prepared: Use Read charging fault lights for a pattern seen while charging. Not sure -> prepared: Save your observations and compare the matching manual before continuing. check-2: Which color was seen during use? Blue -> steps: Record the number and whether it was solid or flashing. Red, solid or flashing -> service: A flashing red light indicates a battery fault; solid red indicates a main-body fault in this manual. Contact Dyson with the exact pattern. Unclear or another pattern -> prepared: Save the observation and compare the exact manual diagram; do not guess. CARE STEPS (only when the route reaches steps) [ ] 1. Keep the observation in context Leave the machine stopped while recording the light you saw. Do not repeatedly trigger it just to reproduce a fault. Record that the charger was disconnected. Look for: Charging lights must be interpreted in the separate charging task. Source: dyson-v8-manual, p11 Diagnostics – lights during use; Operation [ ] 2. Match steady blue lights Three solid blue lights mean high charge; two mean medium; one means low. These are charge-level indications during use. Look for: The number of solid blue lights is not a motor fault code. Source: dyson-v8-manual, p11 Diagnostics – lights during use; Operation [ ] 3. Match flashing blue One flashing blue light during use means the battery is empty and needs recharging. Record steady or flashing along with the number of lights. Look for: A flashing light is different from one steady low-charge light. Source: dyson-v8-manual, p11 Diagnostics – lights during use; Operation [ ] 4. Choose the next action For flashing blue, recharge with the correct Dyson charger after the machine has cooled following full discharge. For steady blue with a separate symptom, choose the relevant weak-pickup, brush or pulsing task. Look for: Blue lights alone do not prove the cause of a suction or brush complaint.

Save a useful support record Keep the context, pattern and associated symptom together. If a red light or unsafe symptom appears, stop using the machine and contact Dyson; keep the battery and main body closed. Look for: A manufacturer referral uses the exact observed pattern, not a guessed replacement part. Source: dyson-v8-manual, p11 Diagnostics – lights during use; Operation OBSERVATIONS Observation context (required): ____________________ Choices: During use, charger disconnected During-use pattern (required): ____________________ Choices: Three solid blue / Two solid blue / One solid blue / One flashing blue Next action (required): ____________________ Choices: Cool after discharge, then recharge correctly [further care/preparation needed] / Follow the task for the separate symptom [further care/preparation needed] / Charge level understood; no separate symptom RESULT CHECKS [ ] The during-use light pattern and charger context are recorded. [ ] The next action follows the light meaning and any separate symptom, without opening an electrical enclosure. NEXT CARE A light was observed while using the machine, especially before it stopped. As needed for this condition. No fixed calendar interval is specified for this check; choose your own review date if useful.
