Maintenance And Inspection - Hitachi WH 8DC2 Bedienungsanleitung

4. Use a tightening time suitable for the screw
The appropriate torque for a screw differs according
to the material and size of the screw, and the
material being screwed etc., so please use a
tightening time suitable for the screw. In particular,
if a long tightening time is used in the case of
screws smaller than M6, there is a danger of the
screw breaking, so please confirm the tightening
time and tightening torque beforehand.

MAINTENANCE AND INSPECTION

1. Inspecting the driver bit
Using a broken bit or one with a worn out tip is
dangerous because the bit can slip. Replace it.
2. 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.
3. 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,
for they melt plastics.
4. Storage
Store the impact driver in a place in which the
temperature is less than 40°C, and out of reach of
children.
