Recommended Basic Settings as Guidelines
The following values are practice-oriented guidelines. The risk assessment, filter selection, operating instructions, and company specifications always remain decisive.
| Situation | Recommendation |
|---|---|
| Long wearing time | Check battery level before starting, keep a replacement battery ready, and perform airflow test |
| Dust exposure | Check P3 particle filter and pre-filter according to the deployment plan and replace in time |
| Warm environment | Ensure a comfortable fit of the hood; the airflow helps maintain a fog-free field of vision |
| High physical load | Only start with a passed function check and take warning signals seriously |
Pro Workflow: How to Start Your Assignment Correctly
- Check the hazardous substance, particle load, and duration of use.
- Select the appropriate filter combination according to the risk assessment.
- Charge the battery and check for visible damage to the fan, hose, and hood.
- Correctly mount filters, pre-filters, and adapters.
- Perform an airflow test using the flow meter.
- Put on the hood and adjust the headband and neck seal comfortably.
- During work, pay attention to warning signals, airflow, and wearing comfort.
Troubleshooting: 4 Typical Problems
1. Low Airflow Warning Signal
Check filter for saturation, check hose for kinks, and check battery level. Then repeat the airflow test.
2. Field of Vision Fogs Up or Air Feels Uncomfortable
Check hood fit, air ducting, and hose connection. The SR 602 features air ducting that supports comfort and a clear field of vision.
3. Short Battery Life
Fully charge the battery, consider the age of the battery, and plan for a replacement battery during long shifts.
4. Uneven or Restricted Airflow
Check filter mounting, adapter, pre-filter holder, and hose routing. Replace blocked or heavily soiled components.
Maintenance: 5 Points for Reliable Protection
- Perform a visual inspection of the fan, hood, hose, and connections before every use.
- Replace filters and pre-filters according to load, specifications, and warning indicators.
- Clean the hood and components with suitable cleaning wipes.
- Store the battery in a dry, clean place according to temperature specifications.
- Do not improvise repairs on damaged parts; use only matching original parts.
