ENVIRONMENTALCONSIDERATIONS
Thefollowingrecommendationscanbeuseful:
• Becomefamiliarwithpertinentlegislation currentlyoperativeinthecountryofuse,andbe certainitisproperlyunderstood.
• Intheeventthatnostatutoryregulationsexist, askforspecificinformationfromthesuppliersof lubricants,fuel,antifreezeandcleaning compoundsregardingtheireffectsonhumans andontheenvironment,andhowtostore, handleanddisposeofthesesubstancessafely.
