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
Milwaukee original instructions · English printed page 14 · reviewed 19 September 2026 · The original manufacturer instructions explicitly name this model. Catalogue kit variants are matched through the Milwaukee UK product listing. The combined manual has distinct columns: M12 FHIR14LR 2.52 m/s² and M12 FHIR38LR 2.80 m/s², both K=1.5. Only the matching column is used. · Match your exact model, generation, attachment and working mode.
| Working mode | Declared m/s² | Uncertainty K m/s² |
|---|---|---|
| Ratchet · declared test | 2.52 | 1.5 |
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.
