Solution
The electric screwdriver
gets hot
Is the ON time of the electric
screwdriver too long?
Alternatively, is the OFF time too
short?
Review the operation time.
The rated operating time is 0.5 sec. ON and 3.5 sec.
OFF.
Aim at 15 screws per minute. (p. 4)
Is the input voltage 115 V AC?
Check the input voltage.
Even though the output torque is set
to the specification lower limit value,
does the screwdriver get hot to a level
where you cannot touch it?
When the output torque becomes higher, the electric
screwdriver becomes hot.
If it gets hot to a level where you cannot touch even
with the specification lower limit value, a failure is
suspected.
The rotation speed is not
stabilized.
Is the electric screwdriver heating up?
Is it the same electric screwdriver?
The specification value of the rotation speed is a
standard.
The rotation speed could change due to
temperature or mechanical loss of the main unit
or grease conditions. Also, it differs by the unit.
