The RCV3 is the simplest machine we sell to run, but the first hour matters: a coil loaded backwards or a feed length set too long will make a good machine look bad. This is the setup we walk customers through on the phone. The RCV3 handbook (PDF) has the diagrams.
1. Receiving the machine
The RCV3 ships by freight in a 38" × 25" × 35" crate at about 189 lbs. We include liftgate delivery, so the driver lowers it to the ground — you do not need a dock or forklift. Before you sign:
- Walk around the crate and note any damage on the delivery receipt.
- Photograph anything that looks crushed or punctured. This is what makes a freight claim painless.
Two people can move the uncrated machine; it rolls on its own caster wheels once it is on the floor.
2. Where to put it
- Flat, dry floor. Lock the casters once it is in position.
- Worktable height is 25.8", so it sits naturally at the end of a standard packing bench.
- Leave room on both sides for the carton to pass through and for the coil door to open.
- A standard 110V outlet. The machine accepts 110–240V, 50/60 Hz, and draws 250W — no dedicated circuit.
- Ambient 41–104°F, 35–85% humidity. Keep it out of direct sun; heat softens PP strap and changes the seal.
3. Which strap to buy
PP (polypropylene) only — no PET, no steel. Width 1/4"–5/8", thickness 0.02"–0.033". The coil holder takes standard 8" and 9" cores (3" also fits). Our 1/2" PP coil on an 8" core is the one most RCV3 customers run.
4. Loading the coil
- Power off.
- Open the coil compartment and slide the coil onto the holder so the strap pays off in the direction of the arrow on the holder. A coil loaded backwards is the number-one cause of "it won't feed".
- Cut the strap end square and clean — no burrs, no fuzz. A ragged end jams in the feed rollers.
- Feed the strap end into the feed rollers under the table until you feel them take it, then power on and use the feed function to bring the strap out through the slot on the worktable.
- Close the compartment.
If the strap comes out curled or twisted, it is usually riding on the coil flange — reseat the coil.
5. Your first three cartons
The RCV3 leaves the factory with sensible settings, so start there:
- Wrap the strap around the carton by hand and push the end into the slot on the table.
- The machine tensions, heat-seals, cuts and feeds the next length — under three seconds.
- Check the joint: tug it hard. It should not peel. Check the carton: the strap should be snug but not cutting into the corners.
Do three in a row before adjusting anything.
6. The three adjustments, and when to touch them
All three are on the front panel.
Tension (11–110 lbs)
Turn it up if the strap is loose on the carton; turn it down if the carton corners crush or the strap snaps. Light single-wall cartons live at the bottom third of the range. Change it one step at a time.
Cooling time
The seal is a heat weld; cooling time is how long the machine holds the joint before releasing. If you raise the tension and joints start to peel, add cooling time — that is exactly what it is for. In a hot shop, add a little too.
Strap feed length
How much strap the machine pays out after each cycle. Too short and you are pulling strap out by hand for every carton; too long and it curls on the table and jams. Set it so there is just enough to reach around your usual carton with a hand's width to spare.
7. Daily habits that prevent service calls
- Brush strap dust out of the sealing area at the end of the shift.
- Do not oil the rollers. Oil on the strap stops it sealing.
- Power off and unplug when idle.
- Keep spare coils off the floor and out of the sun.
FAQ
Can I use it for pallets? No — 110 lbs of tension and PP strap are for cartons. Pallets and lumber are the RCV2 with PET strap.
Is there a maximum carton size? No. The tabletop is open; only a minimum of 2.4" × 2.4".
Blue or white? Same machine, two colours (RCV3 and RCV3B).
