WARNING: When using electric tools, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury, including the following.

5. Consider Work Area Environment Do not expose tool to rain Do not use tool in damp or wet locations. Keep work area well lit. Donotusetoolinpresenceofflammable liquids or gases.

6. Guard Against Electric Shock Preventbodycontactwithgrounded sufaces. For example: pipes, radiators, ranges, refrigerator enclosures.

7. Keep Children Away Do not let visitors contact tool or extension cord.Allvisitorsshouldbekeptawayfrom work area.

8. Store Idle Tools Whennotinuse,toolsshouldbestoredina dryhighorlocked-upplace-outofreachof children.

9. Do Not Force Tool Itwilldothejobbetterandsaferattheratefor whichitwasintended. 10. Use Right Tool Donotforcesmalltoolorattachmenttodothe jobofaheavy-dutytool.Donotusetoolfor purpose not intended.

MAINTENANCE

NOTE: The internal components of the pump and piston area have very close clearances and are sensitive to damage from dust, dirt, contamination of the hydraulic fluid or improper handling. The disassembly of the pump housing requires special tools and training, and should be attempted by a qualified repair person. The improper servicing of electrical components can lead to conditions that could cause serious injury.

ANY ATTEMPT BY UNAUTHORIZED PERSONNEL TO SERVICE THE INTERNAL COMPONENTS OF THE PUMP AREA WILL VOID THE WARRANTY.

HELPFUL HINTS FOR HOLE PUNCHINGEachofthepunchesisprovidedwithasharppointatitscenter.Iftheholelocationsarecenterpunched,thepointontheendofthepunchmaybeusedto"find"thecenterpunchedspot.
