TopDrive hex ¼ ”
Torque Soft/Hard 5-12Nm/5-12Nm
Battery Type 2.0Ah or 3.3ah Makstar (not supplied)
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.
Noise sound pressure 71 dB(A)
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
Noise K factor 3 dB(A)
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.
No load speed 390 rpm
Vibration K factor 1.5 m/sec²
