Warranty and After Sales Service in Syria: What the Machine Contract Should Cover

Warranty and after sales service in Syria is settled by the machine contract, not by what a salesperson says on a call. Four fields decide the outcome: where the clock starts, which parts are covered and which are wear items, how a claim is filed and proved, and who answers first when the line stops. A plant running a press at 31.5 MPa beside a vibration system at 3,800 to 4,500 times per minute carries two failure families, and a contract that does not separate them leaves the argument to the day the fault happens.

What has to be written into the contract before the machine is built?

Two clauses carry most of the risk, and both are cheap to agree while the machine is still a drawing. The first is where the warranty clock starts. Shipment date and arrival acceptance date are different days, and on a 34 t frame moving by sea the gap between them is not cosmetic. Name the date in writing, with the document that proves it.

The second is the coverage boundary, written by part number rather than by a word like equipment. The phrase the machine means one thing to a service desk reading an order and another to a plant manager standing beside a stopped line. On a QST1800 the scope question alone touches a 104 kW installed capacity, a 1,400 x 1,400 x 30 mm pallet and 280 kN of vibration force.

• Start point: the exact date plus the document that proves it.
• Scope: the machine, the line and each covered assembly named by part number.
• Wear list and exclusions: every excluded item, plus what voids cover.
• Response chain: who receives a report and what the first written answer holds.

Where warranty cover ends and the wear part list begins

Moulds, pallets, vibration motors and seals sit near that line, and the contract must place each one on a side. The test is not the part name but the mode of failure. A mould takes a full press stroke on every cycle, so on a 15 to 23 s cycle it sees thousands of strokes in one shift. A vibration motor turns at the 3,800 to 4,500 times per minute the spec sheet quotes.

That does not drop all of those parts out of cover. A wear part failing far from its normal wear curve, or at a casting rather than at the wear surface, is a different event. Classify by failure mode, with a part number against each item in an annex: normal consumption is a buyer cost, premature or structural failure is a claim. Add the two inspection points that make the classification stand up, at day 7 and day 28 of production.

• Mould: even cavity wear is buyer cost; a crack at the frame is a claim.
• Pallet: rounding edges after thousands of passes is consumption; a warped batch is a supply claim.
• Vibration motor: worn bearings are consumption; a young unit losing a winding is a claim.
• Seals and oil: consumed on a schedule, and that schedule belongs in the manual.

How is a claim filed and proved?

A claim arriving without evidence is a conversation, not a claim. The contract should fix the file the buyer has to produce, so the service desk can act on the first exchange instead of the fifth. That file is short on an automated line: part number and serial, running hours on the counter, alarm text from the panel.

Then comes the chain. It names who receives the report, inside which coverage window, and what the first written answer holds. A sequence that works is an acknowledgement, a remote diagnosis on that file, and a plan with one of three outcomes: a parameter change the operator applies, a part number released for dispatch, or a request for a site visit.

• Part number and serial of the failed component, read off the part.
• Running hours from the machine counter, because a claim is dated by hours too.
• Photographs and a short video of the part in place, taken before dismantling.
• Alarm code and fault position text photographed off the control panel.
• Pressure and cycle time readings taken at the moment of failure.

Remote diagnosis, parameters and the parts that travel

Remote support is only as good as the data path behind it. A line with cloud remote monitoring and a self organised wireless network lets an engineer read status and fault history from outside the plant, so the first diagnosis does not wait for a flight. A standalone press is served more slowly, from panel readings, photographs and a call with the operator.

When a part has to ship, packing and marking carry as much weight as speed. The crate should show the part number, the machine serial and the quantity on the outside, be packed for humid conditions and two handling stages, and travel with the invoice and packing list inside the same documents. The contract should name who carries the export leg, the transit leg and the clearance leg, and the address closing each one.

When does an engineer have to travel to the site, and who carries the cost?

A site visit is the most expensive step in the chain, so it should have a trigger rather than be the default. Two triggers are standard. The first is installation and commissioning, where the frame is set, levelled and run against the target cycle before handover. The second is a fault the remote chain cannot close after the agreed evidence is supplied, typically a mechanical failure inside the frame or a control fault that survives a parameter reset.

Travel terms belong in the same clause. Name who books the ticket, who covers travel, lodging and local transport, and how many working days the visit includes. These items differ from one buyer to the next, so the contract should carry your agreed figures rather than a generic sentence.

The two inspections that catch most early faults sit in the same clause. At day 7 of production, re-torque the frame and mould fixings, check hydraulic pressure against the 31.5 MPa rated figure, and review the first week of alarms. At day 28, compare the mix design, cycle time and mould wear with the target output. Both produce a signed record.

The four link response chain to insist on

Whatever the wording, a response chain has four links and the contract should make each one explicit. The first is the report channel and the acknowledgement, with a coverage window that matches the shift pattern of the plant. The second is the diagnosis and the plan, in writing, with the reason stated when the answer is a visit. The third is the material answer: a parameter, a part number or a visit. The fourth is the closing record, with the root cause, the parts replaced and the parameters changed.

Then attach the machine data that keeps the chain fast, at delivery rather than at the first breakdown: model and serial number, installed capacity, pallet size, cycle time and pressure setting, with the plant contact and the site address. Start the record at unloading too, photographing the crate, noting the serials of the main assemblies and logging the counter where it stands. A unit such as the QST6-15, on a 980 x 680 x 20 mm pallet at 68 kN of excitation force, is serviced from that file.
