Maintenance And Inspection - Hitachi WH 12DAF2 Handling Instructions Manual

MAINTENANCE AND INSPECTION

1. Inspecting the driver bit (WH12DAF2)
Using a broken bit or one with a worn out tip is
dangerous because the bit can slip. Replace it.
2. Inspecting the socket (WR12DAF2)
A worn or deformed hex. or a square-holed socket
will not give an adequate tightness to the fitting
between the nut or anvil, consequently resulting in
loss of tightening torque. Pay attention to wear of a
socket holes periodically, and replace with a new one
if needed.
3. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so may result in serious hazard.
4. Cleaning of the outside
When the impact driver is stained, wipe with a soft
dry cloth or a cloth moistened with soapy water. Do
not use chloric solvents, gasoline or paint thinner, as
they melt plastics.
5. Storage
Store the impact driver in a place in which the
temperature is less than 40°C, and out of reach of
children.
