Upon the completion of disassembly and repair, measure the insulation resistance and conduct a dielectric
strength test.
Insulation resistance: 7M or more using a DC 500 V megohm tester
Dielectric strength: AC 4000 V/1 minute, with no abnormalities
The allowable deflection level of the saw blade shall be as follows:
When the unit becomes soiled, use a clean, soft rag moistened with soapy water to clean it. Never use
chloric solvents, gasoline or thinner (which tend to damage plastic material) for cleaning.
