24MM SDS-PLUS ROTARY HAMMER

K factor
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.

Weight
As a permanent member of EPTA, the European Power Tool Association, Makita is committed to publishing weights in according with the EPTA standards. This standard is derived from EU Directive 1999/44/EC. The standard is a strict agreement with EPTA as to how different machines are to be weighted, so you can compare machines across the market.

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.

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
