MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
• Clean out the upper and lower guards to ensure
there is no accumulated metal chips which may
impede the operation of the lower guarding system.
A dirty guarding system may limit the proper operation
which could result in serious personal injury. When
using compressed air to blow metal chips out of the
guards, wear a proper eye and breathing protection.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Inspecting saw blade
• Check the blade carefully for cracks or damage
before and after each use. Replace a cracked or
damaged blade immediately.
• Continuing to use a dull blade may cause a danger-
ous kickback and/or motor overload. Replace with a
new blade as soon as it no longer cuts effectively.
• Carbide-tipped saw blades for metal cutter
cannot be re-sharpened.
