How to use

Before use, verify the condition of the insulated handle and ensure there are no visible damages or cracks. Confirm that the screwdriver is appropriate for the screw head size to avoid slipping. Use the screwdriver on live installations only within the rated 1000 V and follow applicable electrical safety procedures, including proper personal protective equipment and isolation practices where required. Apply steady axial force and keep the tip engaged with the screw head while turning to maintain control and avoid damaging the fastener.

Recommendations

Inspect the insulation regularly and replace the tool if the handle shows wear, cracking, or contamination. Do not exceed the insulation rating; for voltages above 1000 V or where tool certification is required, use equipment explicitly certified for those conditions. Store the screwdriver in a dry, clean environment and keep it separate from non-insulated tools to avoid accidental misuse.
