SKIN & RESPIRATION ISSUES

POSSIBLE CAUSES

CORRECTIVE ACTIONS

1 2 3 4 5

Too low fluid level in tank Pump sucks air High return flow Too small tank Contamination by Emulsion for example

1 2 3 4 5

Fill up with oil Check & prevent air entry Pipe entry below oil surface System designed as total volume > 8 x Pump volume/min Identify source, add anti-foam

1 2 3 4 5

Alignment of nozzles & flow Too low oil flow Too low additive quantity Too high cutting speed Too high oil temperature

1 2 3 4 5

Re-align nozzle and check flow Check pump, open valves Add EP-additive, use higher duty oil Use higher duty oil Checking cooling unit and fluid volume in tank

1 2 3 4

Too high oil temperature Open Tanks and chips containers Mist extractor not working Wrong product

Metal chips in oil, Corrosion contact Water in oil Contamination by chemicals Oil ageing Yellow metal staining

1 2 3 4 5

Check filter, use magnetic filter if needed Check water content using crackle test, send sample to lab Send sample to lab Check odour, Send sample to lab Use oil free of active sulfur

1 2 3 4 5

Fluid flow, nozzles Volume, Pressure Abrasive wear Too high oil temperature Tramp oil Contamination

1 2 3 4 5

Check flow quality & nozzles not blocked Open valves, check for blockage Check Filters are not blocked Check cooling unit and tank fluid level Send fluid sample to Lab, add Additive Pack

1 2 3 4

Extreme Temperature Contamination by rain water Reaction with container Too long storage

1 2 3 4

Adapted storing (+5 to + 40°C) Correct storage conditions, lying (3 & 9 o‘clock) Don‘t use galvanized or painted containers Check manufacturer‘s advice for max storage duration
