Makita DUB186RT 18V BLOWER LXT

Ni-Cad (Nickel Cadmium) battery.
These batteries are reasonably priced but are very damaging to the environment. They also need to be completely discharged and cool to be able to accept a full charge.

Ni-MH (Nickel Metal Hydride) battery.
With this battery technology it was possible to increased the amperage to 3.
0Ah, they are also a better option environmentally than Ni-Cad. They can be fully charged whether they are warm or partially discharged.

Li-ion or Lithium-ion batteries.
Lighter weight, quicker charging and with more run time than an equal voltage Ni-Cad or Ni-MH battery. These batteries have a chip that communicates with the charger for optimum charging. Lithium-ion batteries also offer much improved charge retention over long periods of storage. Li-ion batteries do not have to be fully discharged before charging in fact they can be charged at any time with no ill effect.

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.

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.

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.

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.
