2. Start & Adjust Gear: Long press the power switch to start the device, adjust the gear according to the scenario:

            ￮ Fine mist: Air humidification, pet care, foliar fertilization

            ￮ Medium mist: Daily home cleaning, potted watering

            ￮ Direct spray: Long-distance watering, stubborn stain cleaning

3. Correct Spraying: Keep a distance of 15-30cm between the nozzle and the target, move the device at a constant speed, and avoid spraying the same part for a long time. When spraying pesticides, stay away from the downwind direction and keep the device vertical to prevent uneven spraying or local water accumulation.

Post-use Maintenance of Handheld Electric Sprayer

Neglecting post-use maintenance is the main reason for early equipment failure. Standard maintenance can significantly extend the service life:

1. Thorough Cleaning: Pour out the remaining liquid, fill with clean water, tighten the cover and start the device to spray for 1-2 minutes; repeat 2-3 times until the outflowing water is free of residue. For pesticide spraying, rinse with lye first, then clean with clean water thoroughly. Disassemble the nozzle and filter screen, brush gently with a soft brush—do not poke the nozzle hole with hard objects to prevent damage.

2. Dry Storage: Wipe or air-dry the liquid storage pot, nozzle and spray rod to ensure no water residue, avoiding motor short circuit and part rust caused by humid environment. Store disassembled parts properly to prevent loss or damage.

3. Battery Maintenance: For long-term non-use (more than 1 month), fully charge the battery first, then store in a cool, dry and ventilated environment. Recharge the battery every 1-2 months to avoid damage from low power. Unplug the charger in time after full charge, do not overcharge for a long time.

4. Whole Machine Storage: Assemble the dry device completely, place it out of children's reach, away from fire sources, high temperature and corrosive items. Avoid collision and falling to prevent damage to the body and parts.

Common Faults of Handheld Electric Sprayer: Water Output Abnormalities & Solutions

Water output abnormality is the most common fault, including no water output, uneven water output, water leakage and intermittent water output. Users can troubleshoot and solve it by themselves without professional maintenance:

1. No Water Output (Motor runs but no water / No water at all)

Common Causes: Clogged nozzle/filter screen; insufficient liquid in the pot; insufficient air pressure due to loose pot cover; low battery power; dry/hard, loose or damaged cup leather; internal air not discharged from new devices.

Solutions: Add liquid to the safety water line, clean the nozzle and filter screen; tighten the pot cover and check the sealing ring; fully charge the battery; soak dry cup leather with a small amount of engine oil (replace if damaged); run the new device idle for 30 seconds to discharge internal air before adding liquid.
