Instructions for the prevention of functional failures and damage to equipment when performing cleaning operations on fork lift truck 2. Cleaning and servicing of chains Lifting chains fall into the category of safety elements. Their servicing and lubrication must be carried out with great care, as befits safety elements. Lack of lubrication causes rapid wear of chains. The intervals indicated in the servicing checklist apply to normal operating conditions. Under rugged working conditions (dust, high temperatures) more frequent lubrication becomes necessary. It is advisable to use the chain spray indicated in the lubrication schedule. With a clean chain (dust and grease crusts to be removed beforehand) this will ensure penetration of the lubricant. Mere external application of grease does not provide adequate lubrication. • Chains should not be excessively dirty. • Do not clean chains hy means of steam jets, i.e. do not direct the steam jet directly on to the chain. • Paraffin derivates only must be used for cleaning purposes (petrol, petroleum or diesel fuel). • Chains must be lubricated whenever they have been cleaned. • Corrosive products and acids must not come into contact with chains, as they will lead to their destruction. • When servicing or replacing lift chains, check for uniform tension and for aligned and smooth passage over the guide rollers. !
1. Cleaning operations, general • Unplug the battery connector or disconnect the battery, before commencing any cleaning operations. • Only non-inflammable liquids must be used when performing cleaning operations (for cleaning and servicing of chains refer to section 2). • Do not use water or a steam jet when cleaning electric and electronic assemblies or components. Use vacuum intake air, weak compressed air and a non-metal brush. • Carefully cover all delicate components, especially electric and electronic assemblies and components before applying water or a steam jet. • After completion of steam jet cleaning, grease the vehicle in accordance with the lubrication schedule. Friction surfaces, guide rollers and chains must only be greased with the lubricant specified for the respective operating conditions (normal operating conditions/operation in cold storage facilities). • Parts susceptible to corrosion must be subjected to the prescribed aftertreatment. • Before putting the vehicle into operation again, ensure that the electric/ electronic assemblies are dry. If necessary, dry them using air. Ensure that any residual water or liquid detergent still present on the chassis or inside the vehicle cannot penetrate into electric or electronic assemblies as a result of vehicle movements. • The entire vehicle must be perfectly dry, before operations in cold storage facilities are resumed. • Perform several braking tests (drying out the brakes) before putting the vehicle into operation again. • No sealing spray should be used, as sprayed surfaces tend to increase the attraction of dust and dirt. • Limit the application of contact spray to as little an area as possible.
