Important Safety Information
WARNING: These gloves are intended as an auxiliary safety tool for electrical equipment up to 400V. They are not primary insulation for high-voltage work. Always follow all local and national electrical safety codes and regulations.
- Use these gloves only for voltages below 400V.
- Always operate in a dry environment. Moisture significantly reduces insulation effectiveness.
- After correctly wearing the gloves, avoid touching charged bodies with any part of your hand other than the insulated palm and fingers.
- Inspect gloves thoroughly before each use for any signs of damage, punctures, tears, or degradation. Do not use damaged gloves.
- Do not use these gloves if they are wet or damp.
- Store gloves properly to prevent damage and degradation.
Setup and Pre-Use Inspection
Before each use, a thorough inspection of your Estink insulated gloves is critical to ensure their protective integrity.
- Visual Inspection: Examine the entire surface of both gloves for any cuts, tears, punctures, cracks, or signs of wear. Pay close attention to the rubberized palm and finger areas, as these provide the primary insulation.
- Air Test (Inflation Test): Gently roll the cuff of the glove to trap air inside, then squeeze the cuff to inflate the glove. Listen and feel for any air leaks, which would indicate a puncture. Alternatively, you can submerge the inflated glove in water and look for bubbles.
- Cleanliness: Ensure the gloves are clean and dry. Any dirt, grease, or moisture can compromise their insulating properties.
- Flexibility: Check that the gloves remain flexible and are not stiff or brittle, which could indicate material degradation.

If any damage is found during inspection, do not use the gloves. Replace them immediately to ensure your safety.
Operating Instructions
Follow these steps for safe and effective use of your Estink insulated gloves:
- Ensure Proper Fit: Select gloves that fit snugly but allow for full dexterity. An improper fit can hinder movement or reduce protection.
- Wear Correctly: Put on the gloves, ensuring they cover your hands and wrists adequately. The cuff should be positioned to prevent accidental contact with uninsulated areas.
- Maintain Dry Environment: Always work in a dry environment when handling electrical components. These gloves are designed for dry conditions.
- Handle with Care: The textured rubber palm provides an anti-slip grip, enhancing control and reducing the risk of accidents when handling tools and equipment. Utilize this feature for precise work.
- Voltage Limit: Remember these gloves are rated for auxiliary safety up to 400V. Do not exceed this voltage rating.

Maintenance and Storage
Proper maintenance and storage are essential to preserve the protective qualities and extend the lifespan of your gloves.
- Cleaning: If the gloves become dirty, gently wipe them with a damp cloth and mild soap. Rinse thoroughly and allow them to air dry completely before storage or next use. Do not use harsh chemicals or abrasive cleaners.
- Drying: Ensure gloves are completely dry before storage. Store away from direct sunlight and heat sources.
- Storage: Store gloves in a cool, dry, and dark place, away from ozone, chemicals, oils, solvents, and sharp objects. Avoid folding or creasing the gloves, which can cause material stress. Ideally, store them flat or hung.
- Inspection Frequency: Regularly inspect gloves even when not in use, especially if stored for extended periods.
- Aging Resistance: The nylon fabric is designed to resist aging, but proper care will further enhance its longevity.

Troubleshooting
This section addresses common concerns regarding the condition and performance of your insulated gloves.
| Problem | Possible Cause | Solution |
|---|---|---|
| Gloves show signs of damage (cuts, tears, punctures). | Physical damage from sharp objects, abrasion, or improper handling/storage. | Do not use. Replace the gloves immediately. Damaged gloves offer no protection. |
| Gloves feel stiff or brittle. | Material degradation due to age, exposure to extreme temperatures, chemicals, or improper storage. | Do not use. Replace the gloves. Material integrity is compromised. |
| Gloves feel damp or wet. | Exposure to moisture during use or storage. | Allow gloves to air dry completely in a cool, dry place before use. Do not use damp gloves for electrical work. |
| Reduced grip on tools. | Dirt, grease, or oil on the glove surface; wear of the textured rubber. | Clean gloves as per maintenance instructions. If the texture is significantly worn, consider replacement. |
For any concerns not addressed here, or if you suspect the gloves' protective capabilities are compromised, discontinue use and replace them.
