The MT2838 3/8" ratchet is designed to fasten and unfasten threaded
fasteners while operating under recommended conditions. Note
the directional setting of the reversing lever before depressing the
throttle. Ensure body stance to be in excellent balance and have full
control of the tool before use. Be fully alert as sudden reaction torques
and directional changes may unexpectedly occur. Be aware that air
ratchets are not torque wrenches or pry bars. Joints and fasteners
requiring a specific torque must be checked with a torque wrench
as the final step. Using the air ratchet while the power is in the "off"
position, to tighten or break-free fasteners, can irreversibly damage its
internal mechanism and will void any remaining warranty.
