6 Notes on maintenance6.1 Prepare the truck for the servicing and maintenance operationsAll required safety measures must be taken to prevent any accidents in the course ofthe servicing and maintenance operations. The following preparatory operationsmust be performed:f– Park and lock the truck securely (see chapter E).– Unplug the battery connector, thus securing the industrial truck against accidentaloperation.– When work has to be performed under the jacked-up industrial truck, suitablemeasures must be taken to prevent any dropping, tilting or slipping of the truck.When lifting the industrial truck, the instructions contained in chapter “Transportationand commissioning” have to be observed (refer to chapter C).6.2 Cleaning the lifting chainsmIt is important to keep all lifting chains and pivots clean and lubricated at all times.Lifting chains are safety elements.Chains must not be excessively dirty. For cleaning, only paraffin derivatives (such as,for example, kerosene or diesel fuel) may be used.Never clean chains with steam jet pressure washer, cold cleaner, or chemicalcleaners.6.3 Inspection of lifting chainsImproper wear and external damages:According to the official regulations a chain is regarded as worn out if it has elongatedby more than 3% in the section where it runs around the deflection pulley. For safetyreason we recommend to replace a chain when it has elongated by 2%.mA chain should also be changed immediately when external damages are detected,as such damages result in fatigue fractures after a certain time period.If the industrial truck is equipped with two lifting chains, always both chains must bereplaced. The equal load distribution to both chains can only then be guaranteed.When replacing chains, the connection bolts between chain anchor and chain mustalso be renewed. As a rule, only original parts may be used.1102.GBF 9
