In the ceiling, which
Assembling the frame and its fastening to the base is carried out using screws and dowels with a step 30-40 cm.
Speed ranges-for
Among other functional capabilities of screwdrivers, attention should be paid to the following:
Power source
The listed shortcomings are overcome in lithium-ion batteries, but they are more expensive at the price.
To charge them for
In addition, nickel-cadmium batteries are prone to self-discharge and it does not make sense to charge them for the future-the charge will not remain.
Battery capacity will
- However, if you begin to charge such a battery after incomplete discharge, zones that do not form an electric charge form in it.
Are durable, capable of
- Bquighties in screwdrivers use nickel-cadmium and, more modern, lithium-ionic.
To avoid thread breakdown
- The torque regulator makes it possible to experimentally choose the necessary value for specific working conditions to avoid thread breakdown, damage to the slots or premature discharge of the battery.
In low -power
- So that this time is acceptable, the voltage of the battery and its capacity must correspond to the power of the used electric motor.
