To maintain the effectiveness of the double insulation system, follow the precautions
described below:
1. Always contact your dealer or an authorized service center when assembling,
disassembling or replacing parts other than accessories or carbon brushes. Improper
assembly and/or replacement with wrong parts may result in eliminating the double
insulation-feature.
2. Clean the exterior of the power tool with a soft cloth moistened with soapy water, and
dry thoroughly. Chloric solvent, gasoline, and thinner will cause plastic components to
dissolve.
REPLACEMENT PARTS
When servicing use only identical replacement parts.
