Tool Temperature
POTENTIAL BURN HAZARD
Fixtured tools have higher operating temperatures and do not have
additional thermal protection.
To Avoid Injury:
Wear thermal protective gloves when handling fixtured tools.
Stanley electric tools are thermally protected to prevent overheating.
Temperature is sensed inside the tool, either in the motor windings of E series or
on the resolver board on EA/EB/EC tools and the value is reported to the
controller. The thermal protection does not allow the tool to operate if the tool
temperature raises abnormally – the thermal protector resets automatically when
the tool cools down. The maximum tool temperature before damage occurs is
150°C.
EN60745-1 Hand-Held Motor-Operated Electric Tools - Safety is the most
applicable standard to the E/EA/EB/EC series tools. It defines +60°C as the limit
for thermal rise over ambient of a contactable surface (e.g. if the ambient is 25°C,
the surface limit is 85°C). Since the default limit is 85°C inside the tool
regardless of ambient, no external surface can exceed this value no matter what
the ambient temperature.
Stanley Assembly allows the temperature limit adjustment to provide flexibility
to the professional user. Once a customer changes the setting from the factory
default, it is their responsibility to ensure the safety of the user.
Controller parameter settings can have a significant effect on tool operating
temperatures.
