MT2840A 3/8" Dr. Mini Air Ratchet
FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY
OPERATION
This ratchet wrench is rated at 3/8" USS bolt size. Rat ing must be
down grad ed for spring U bolts, tie bolts, long cap screws, double
depth nuts, badly rust ed conditions and spring fas ten ers as they
absorb much of the impact power. When possible, clamp or wedge
the bolt to prevent springback.
Soak rusted nuts in pen e trat ing
oil and break rust seal before removing with ratchet wrench.
If nut does not start to move in three to five sec onds, use a larger
size ratchet wrench. Do not use ratchet wrench be yond rated
ca pac i ty as this will dras ti cal ly reduce tool life.
The reversing button is used to change the rotation of the tool. When
the button is turned to the left, the tool is in a for ward or right hand
ro ta tion. When the valve is turned to the right, the ro ta tion 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.
