MAINTENANCE AND INSPECTION
WARNING: Be sure to switch power OFF and disconnect the plug from the
receptacle during maintenance and inspection.
1. Inspecting the drill bits
Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace
the drill bit with a new one or resharpening without delay when abrasion is noted.
2. Inspecting the screws
Regularly inspect all screws and ensure that they are properly tightened. Should any of
the screws be loose, retighten them immediately.
WARNING: Using this Jig Saw with loosen screws is extremely dangerous.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the power tool. Exercise due care to
ensure the winding does not become damaged and/or wet with oil or water.
4. Service and repairs
All quality power tools will eventually require servicing or replacement of parts because
of wear from normal use. To assure that only authorized replacement parts will be
used, all service and repairs must be performed by a HITACHI AUTHORIZED SERVICE
CENTER, ONLY.
