1. Which variant was ordered and what is in the crate
The PWD02 is listed as a mobile active-water cleaning machine with dry-steam, wet-steam and hot-water modes for indoor garages and narrow outdoor parking spaces, and the catalogue carries both a without-battery and a battery-included version. Confirm the model wording on the packing list and on the product page at PowerDe PWD02 steam cleaner matches the unit in front of you. Then tick off the accessories: steam hose, wand, nozzle set, water inlet fitting, charger if one was ordered, and the spare consumables agreed in the contract. A missing fitting becomes a delivery argument only after the container is emptied, so photograph the unpacked contents against the list.
2. How the machine will be powered without a battery
The without-battery version of the PWD02 ships alongside the version with a battery included, so the first thing to settle is how the machine you bought is fed, and how that differs from the battery version in the specifications. Write the answer down for the exact version on your order, not for the range in general. The PWD01 and HMW2 models in the same PowerDe cleaning equipment range have their own without-battery versions, and the wording on those pages does not always match the PWD02 page, so keep one set of answers per model if more than one unit is arriving. Then hand those written answers to your electrician — cable route to the work area, circuit rating, protective earth, residual-current protection — instead of a general product description.
3. Which protection functions the machine is expected to provide
The PWD02 page mentions leakage, short-circuit, high-temperature, high-voltage and water-shortage protection, while the version with a battery included is described with a longer list. Ask the supplier to confirm, for the exact version on your order, which protective functions the machine provides and what each one does when it acts. Then ask for the recovery procedure after each trip, and check that the wording in your contract matches the wording on the product page you ordered from. Work from the list of protective functions and not from a count of them, because the count differs between the two versions.
4. What the site water supply and drain can deliver
The PWD02 has dry-steam, wet-steam and hot-water modes, so the water it needs changes with the work. Confirm the inlet pressure and flow available at the bay, the tank volume, the inlet fitting type and size, and whether the tank is fed from a tap or filled by hand. Then settle where the run-off goes. Steam and hot-water cleaning uses far less water than a hose, but the water that does leave the bay carries oil, detergent residue and road grime, and that has to match whatever drainage arrangement the site already has.
5. What the site rules say about steam in that location
The PWD02 targets indoor garages and narrow outdoor parking spaces, and those are exactly the places where steam needs a check. Underground car parks often have rules on hot work, on ventilation, and on blocking escape routes with a machine and its cable. Ask the facility manager three questions before the start date: is steam cleaning permitted in the area, what ventilation is required while the machine runs, and what signage or barrier is expected around a working unit. Get the answers in writing from the party responsible for the site, not from the crew that booked the job.
6. Who operates it and against which surface rules
A high-temperature steam machine can damage what it touches if the nozzle is held too close or used on a surface that cannot take heat. Write the operating instruction down before the first job: which nozzle for which surface, the working distance, the pass speed, and the surfaces to stay off — loose trim, electrical connectors, open bearing housings, painted or vinyl-wrapped panels. Then train to that sheet rather than by shadowing an experienced operator. A written procedure is also the document an insurer or a site auditor asks for after an incident, so keep the signed training record with it.
7. What service cover applies to this variant
Ask the supplier what the service terms cover, for how long, and what ends them, and ask specifically about the version you bought: whether adding or swapping battery packs on site changes the service position. Confirm which components are treated as wear items, what spare parts are held and how long a replacement takes to reach you, and which channel handles a fault — the supplier direct, or a local dealer. Shenzhen PowerDe Automation Precision Equipment describes itself as covering equipment R&D and manufacturing, system integration, customized configurations and technical support, so ask which of those your service agreement actually gives you.
8. What proves the machine is ready for service
Hold a short acceptance test with the supplier's instructions in hand and sign one sheet. Run each mode once — dry steam, wet steam, hot water — and check the water inlet and tank, each protective function you can test safely, and the behaviour on shutdown. Record serial numbers, the supply arrangement used for the test, and any defect with a photo. Two copies, both signed, one for the buyer and one for the supplier, close the delivery and start the service period cleanly.
Before you put the machine to work
The machine ordered without a battery is not a simpler machine; the energy question has moved from the on-board pack to your building, your electrician and your operating discipline. Take the eight questions to the supplier and to the facility manager together, keep the answers with the operating sheet, and treat the acceptance run as the point where those paper answers become a working installation. If your site needs something the catalogue version does not cover — a different power arrangement, a different configuration — raise it during the enquiry at customized steam cleaning equipment rather than adapting the unit after delivery.
