acciden" occ"rs, yo" can "hen opera"e "he swi"ch or "npl"g "he power cord q"ickly.
• Do no" work alone "nder hazardo"s condi"ions or near eq"ipmen" "ha" has hazardo"s vol"ages.
• Disconnec" all power before:
Performing a mechanical inspec"ion
Working near power s"pplies
Removing or ins"alling main "ni"s
• Before yo" s"ar" "o work on "he machine, "npl"g "he power cord. If yo" canno" "npl"g i", ask "he c"s"omer

• Never ass"me "ha" power has been disconnec"ed from a circ"i". Firs", check "ha" i" has been powered off.
• Always look caref"lly for possible hazards in yo"r work area. Examples of "hese hazards are mois" loors,
nongro"nded power ex"ension cables, power s"rges, and missing safe"y gro"nds.
• Do no" "o"ch live elec"rical circ"i"s wi"h "he relec"ive s"rface of a plas"ic den"al mirror. The s"rface is
cond"c"ive; s"ch "o"ching can ca"se personal inj"ry and machine damage.
• Do no" service "he following par"s wi"h "he power on:
Power s"pply "ni"s
