Sound level
Machines have the habit of producing noise. Noise above 80 dB (A) is harmful.  The maximum time of exposure depends on the sound pressure level:

80dB (A): 8 hours
83dB (A): 4 hours
86dB (A): 2 hours
89dB (A): 1 hours
92dB (A): ½ hour
95dB (A): ¼ hours

K factor
The "K factor" is an industry standard uncertanty figure. It represents the natral variation in testing for noise. The true noise figure could be + or - the K factor figure.

The "K factor" is an industry standard uncertanty figure. It represents the natral variation in testing for vibration. The true vibration figure could be + or - the K factor figure.

Vibration
Machines by their nature have the habit of transferring vibration to the user. Use AVT machines to reduce your exposure to vibration. Vibration above
2.5 m / s ² is harmful.

The maximum time of exposure depends on the vibration value:
5 m/s²: 8 hours
10 m/s²: 2 hours
20m/s²: ½ hours

Tri-axial vibration values are used to calculate all Makita vibration figures.
