Vibration data and trigger-time calculator
Calculate this tool’s exposure
Other tools in your current tab’s daily draft are kept when you add this tool. Review the combined daily total in the calculator.
Time and points at your selected magnitude
Times assume no other exposure that day and are rounded down to whole minutes. These thresholds are not safe-time allowances. Keep exposure as low as reasonably practicable.
Manufacturer declarations
Metabo original instructions 17027246 · 10/2024 · pp. 3, 17 · reviewed 18 September 2026 · The manual specifies EN 28662-1 / ISO 8662-11, not EN 28927. Single-event declaration retained for reference; no automatic trigger-time starting value. · Match your exact model, generation, attachment and working mode.
| Working mode | Declared m/s² | Uncertainty K m/s² |
|---|---|---|
| Fastener driving · single-event declaration (reference only) | 3.45 | 1.72 |
Declarations are test results, not workplace measurements. The catalogue starting value is the manufacturer declaration plus published K when K is above 1.5 m/s². Otherwise a 1.5 m/s² allowance is used, including when K is missing. This minimum allowance is a site default; the actual manufacturer K remains in the table above. No HSE tool-type minimum is applied. Missing declarations require an assessed value. Match the working mode, battery and accessory to the manufacturer source. Use your employer’s assessed value where appropriate.
Current and historical sources are included; catalogue coverage and UK sales status are not fully verified. Missing or ambiguous figures require assessment.
