SECTION 1 − SAFETY PRECAUTIONS − READ BEFORE USING Y Warning: Protect yourself and others from injury — read and follow these precautions. 1-1. Symbol Usage Means Warning! Watch Out! There are possible hazards with this procedure! The possible hazards are shown in the adjoining symbols.
WELDING can cause fire or explosion. Welding on closed containers, such as tanks, drums, or pipes, can cause them to blow up. Sparks can 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.
STEAM AND HOT COOLANT can burn. D If possible, check coolant level when engine is cold to avoid scalding. D Always check coolant level at overflow tank, if pres- ent on unit, instead of radiator (unless told otherwise in maintenance section or engine manual). D If the engine is warm, checking is needed, and there is no overflow tank, follow the next two statements.
READ INSTRUCTIONS. D Use only genuine MILLER/Hobart replacement parts. D Perform engine and air compressor (if applicable) maintenance and service according to this manual and the engine/air compressor (if applicable) manu- als. H.F. RADIATION can cause interference. D High-frequency (H.F.) can interfere with radio naviga- tion, safety services, computers, and communica- tions equipment.
SECTION 2 − CONSIGNES DE SÉCURITÉ − LIRE AVANT Avertissement: Protégez vous et les autres des blessures − lisez et suivez ces précautions. 2-1. Signification des symboles Signifie Mise en garde ! Soyez vigilant ! Cette procédure présente des risques de danger ! Ceux-ci sont identifiés par des symboles adjacents aux directives.
LE SOUDAGE peut provoquer un in- cendie ou une explosion. Le soudage effectué sur des conteneurs fermés tels que des réservoirs, tambours ou des conduites peut provoquer leur éclatement. Des étincelles peuvent être projetées de l’arc de soudure. La projection d’étincelles, des pièces chaudes et des équipements chauds peut provoquer des incendies et des brûlures.
D Si le moteur est chaud et que le liquide doit être vérifié, opérer comme suivant. D Mettre des lunettes de sécurité et des gants, placer un torchon sur le bouchon du radiateur. D Dévisser le bouchon légèrement et laisser la vapeur s’échapper avant d’enle- ver le bouchon.
LIRE LES INSTRUCTIONS. D Utiliser seulement les pièces de rechange d’origine. D Effectuer la maintenance du moteur et du compresseur (si applicable) suivant ce manuel et le manuel du moteur/ compresseur (si applicable). LE RAYONNEMENT HAUTE FRÉ- QUENCE (H.F.) risque de provoquer des interférences.
