6.1 Maintenance work
Maintenance work on the chain hoist may only be carried out by qualified persons.
Maintenance work beyond that described in these operating instructions may only
be carried out by the manufacturer or trained after-sales service personnel.
The maintenance intervals below apply to the corresponding mechanism groups in
accordance with FEM 9.511. If the chain hoist is operated in the FEM group specified
by the manufacurer, the correction factors listed below must be applied for quarterly
and annual maintenance work.

6.2 Maintenance intervals
6.2.1 Every day
• Check correct functioning of brake(s).
• Check load chain (visual inspection)
- clean, lubicated and not twisted
• Check bottom hook block (visual inspection)
6.2.2 Every month
• Check suspension of control pendant (cable and strain relief wire must be fitted).
• Check load chain for wear, see page 17
6.2.3 Every three months
• Check hook for wear, see page 17
• Check hook attachment
• Grease output pinion and open step of gearing on electric trolley
• Check attachment of rigid suspension or trolley suspension
• Clean and lubricate chain
• Check chain attachment (2/1 suspension bolt)
6.2.4 Every year
• Check screw connections (tightening torques, corrosion)
• Adjust brake
• Adjust slipping clutch; function of limit switch is also tested when allowing clutch
to slip under overload
• Calculate service life expired. Read operating hours counter if any.
• Check chain stopper (visual inspection)
6.2.5 Every five years
• Gear oil
Change oil, see "Oil change" page 21
6.2.6 Safety note
Periodic inspections including maintenance every 12 months, possibly earlier if so
prescribed by national regulations, to be performed by a fitter engaged by the manu-

conditions (dirt, solvents) necessitate shortening the inspection and maintenance
intervals
