Tool Operation:
This ratchet is designed to remove and install threaded
fasteners .
NOTE:
Actual torque on a fastener is di rect ly related to joint hard-
ness, tool speed, condition of impact socket and the time the
tool is allowed to rotate .
Use the simplest possible tool-to-socket hook up . Every
connection absorbs energ
y and reduces power .
Make sure that the ratchet is turned off and the battery
cartridge is removed before carrying out any work on the
tool. To maintain product safety and reliability, repairs,
maintenance or adjustments should be carried out by a
Matco authorized service center.
