MT1745 Mini Composite 1/4" Impact Wrench
FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY
OPERATION
Soak rusted nuts in penetrating oil and break rust seal before removing with
impact wrench . If nut does not start to move in three to five seconds use a
larger size impact wrench . Do not use impact wrench beyond rated capacity
as this will drastically reduce tool life .
The reversing valve is used to change the rotation of the tool . When the valve
is to the right, the tool is in a forward or right hand rotation . When the valve is
pushed to the left, the rotation is reverse or left hand .
NOTE: Actual torque on a fastener is directly related to joint hardness, tool
speed, condition of socket and the time the tool is allowed to impact .
Use the simplest possible tool-to-socket hook up . Every connection absorbs
energy and reduces power .
