Short answer
The first hours of a new attachment affect its following years out of all proportion. Three jobs are done in those hours: confirming the delivery is complete, running the attachment with the machine at the right settings, and showing the operator what is particular about this attachment. All three look postponable and all three cost money when postponed; an incomplete delivery noticed three months later cannot be proved, a wrong hydraulic setting accumulates damage from day one, and training not given leaves the operator to develop a method of his own.
The delivery check
- Compare what arrived against the packing list: body, bracket, tool (and how many), hose and coupling set, any automatic lubrication unit, operating manual and parts catalogue.
- Look for transport damage: coupling mouths, tool shank, the bracket area and new scratches or dents on the housing. Do this at unloading, before the haulier leaves.
- Record and photograph the serial number. Warranty, spare parts and any future sale all hang on that number.
- Gather the documents in one place: invoice, packing list, manual, warranty document. That folder will be used for the attachment’s whole life.
- Confirm the bracket actually fits your machine, by fitting it rather than by measuring.
Commissioning
- 1
Confirm the hydraulic figures
Compare the machine’s auxiliary circuit flow and pressure against the range the attachment asks for. Make sure the relief valve setting has not been left from the previous attachment.
- 2
Fit it in the right order
Mechanical connection first, hydraulic second. We covered the order and the common mistakes in the fitting guide.
- 3
Do the first greasing
Before running, with the tool pressed up. With an automatic system, confirm the cartridge is fitted and the pump is running.
- 4
Run it off load and listen
Briefly, without setting into material. See that the rhythm is even, there are no leaks and the hoses are not moving excessively.
- 5
Start on softer material
Do not make the first breaks in the hardest material. A gradual load lets both attachment and operator settle.
- 6
Watch the first hours
Housing temperature, the base of the fittings, and the sound. If those three do not change through the first hours, commissioning has gone well.
What to watch in the first hours
What you are looking for is consistency, not performance. How fast a new attachment breaks is not measured in the first hours; what is measured is whether it behaves the same way hour after hour.
Heat is the most important indicator. If the housing is too hot to touch, work stops and the cause is separated: wrong hydraulic setting, insufficient greasing, or something on the machine side?
The second indicator is the base of the fittings. Damp at a fitting on a new attachment says something went wrong at assembly and is corrected early. The third is sound; remembering the sound you heard in the first hours is the only way to notice a change months later.
Run-in is not only for after a repair
New parts bedding in follow the same logic as run-in on an overhauled attachment: working at full load without pause in the first hours prevents a new bushing and seal from seating. We covered it in the run-in guide; the same approach applies to a new attachment.
When should the operator be trained?
The right time for training is delivery day, not a month later. The reason is simple: from the moment the operator starts using the attachment he develops his own method, and training given a month later is trying to change a settled habit.
The content is not general operation but what is particular about this attachment: where the grease points are, in what position grease is given, how the tool is changed, which sound is normal, which sign calls for stopping.
The form that works best is being there for the operator’s first shift. As valuable as any written instruction is being able to say "that sound, there" at the first blank blow.
Do and don’t
Do
- Do the delivery check before the haulier leaves, and photograph it.
- Record the serial number and gather the documents in one folder.
- Confirm hydraulic figures and the relief valve setting at first fitting.
- Do the first greasing before running it.
- Give operator training on delivery day; do not postpone it.
Don't
- Do not let a missing item pass on "they will send it later" without a note on the paperwork.
- Do not make the first breaks in the hardest material.
- Do not work at full load without pause in the first hours.
- Do not carry on through overheating on the grounds that "it is new, it will settle".
- Do not guess service intervals without reading the manual.
