Locking the Screwdriver
The Cordless Screwdriver is fitted with an automatic
spindle locking system. When the screwdriver is locked,
it is possible to use it as a conventional, manual tool. This
is convenient when higher turning torque is needed. The
spindle locks automatically when the trigger switch is
released.
CAUTION:
When the screwdriver is locked, do not exceed
400 in. lbs. (45.2 N•m) turning torque. Safety
could be compromised or damage to tool could
result.
