1 OM-402 1 . Safety Precauti ons − Read Before Using 1.1 Symbol Usage OM-402B -4/97, safety_rom 4/97 Means Warning! W atch Out! There are possible hazards with this procedure! The possible hazards are shown in the adjoining symbols. Marks a special safety message.
2 OM-402 W elding on closed containers, such as tanks, drums, o r pipes, can cause them to blow up. Sparks c a n fly off from the welding arc. The flying sparks, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire.
3 OM-402 MOVING P ARTS can cause injury . Keep away from fans, belts, and rotors. Keep all doors, panels, covers, and guards closed and securely in place. Stop engine before installing or connecting unit. Have only qualified people remove guards or covers for maint- enance and troubleshooting as necessary .
4 OM-402 H. F . RADIA TION can cause interference. High-frequency (H.F .) can interfere with radio navigation, safety services, computers, and communications equipment. Have only qualified persons familiar with electronic equipment perform this installation.
