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
Manufacturer manual review · 19 September 2026 · 2819-002, 10 February 2026 · Left/right handles 4.8/3.3 m/s². No vibration uncertainty is stated in the reviewed technical-data section; noise uncertainty is not used as vibration K. This declaration is for the trimmer-head configuration, not every interchangeable attachment. · Match your exact model, generation, attachment and working mode.
| Working mode | Declared m/s² | Uncertainty K m/s² |
|---|---|---|
| Trimmer head · higher handle | 4.8 | Not available |
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.
