Symptoms
Location to investigate
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)
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.
