Preventive Maintenance
In order to keep your tank cleaning machine servicing you as an efficient tool in your tank cleaning
operations, it is essential to maintain its high performance by following a simple preventive
maintenance programme, which will always keep your tank cleaning machine in good condition.
Good maintenance is careful and regular attention!
The following recommended preventive maintenance is based on tank cleaning machines working in
average conditions. However, you will appreciate that a tank cleaning machine, which has a rough and
dirty job to do, will need more frequent attention than one working in ideal conditions. We trust that you
will adjust your maintenance programme to suit.
Always use only proper tools. Use Toftejorg TZ-79 standard tool kit. Never force, hammer or pry
components together or apart. Always perform all assembly/disassembly steps in the order described
in this manual.
Never assemble components without previous cleaning. This is especially important at all mating
surfaces. Work in a clear well lighted work area.
Note : Recommended tightening torque for all screws: 4-5 Nm.
Every 300 working hours
1. Disassemble machine as described on the following pages.
2. Clean material build-up and deposits from internal parts with chemical cleaner and/or if desired
fine abrasive cloth.
3. Check Slide bearings (pos. 30) for wear. If hole is worn oval to max. diameter more than 12.4 mm,
Slide bearing should be replaced. If end face of Slide bearing is worn more than x mm into Slide

Check Collar bushes (pos. 12) in Gear frame. If holes are worn oval to max. diameter more than
