The symptom pattern

Switch the TPL180 on and the motor runs — you can hear it — but the blade barrel doesn’t turn, or only creeps, and the tool doesn’t cut. That combination matters: it isn’t a dead tool and it isn’t a jammed blade, it’s a motor that’s spinning with nothing connecting it to the barrel it’s supposed to drive. Triton’s own troubleshooting table for the TPL180 lists exactly this symptom, “Barrel not rotating,” against one specific cause: a broken drive belt.

Confirming it, then fixing it

With the tool unplugged, remove the three cross-head screws holding the Drive Belt Cover on the left-hand side of the planer, viewed from the rear. Triton’s manual flags that the front screw is longer than the other two, so it’s worth noting which hole it came out of before you set it aside. With the cover off, a snapped, split or badly glazed belt confirms the fault — that’s the specific cause the manual names for this symptom, not a worn blade or a motor problem.

Replacing it is a full, numbered home procedure in Triton’s own manual, not a service-centre job. Pull the old belt off sideways over the top pulley while turning the bottom pulley by hand, then clean the pulleys and the area around them with a soft brush. Fit the new belt — it has six continuous V-profiles that face inward — over the bottom pulley first, half fit the other end onto the top pulley, then roll it fully into place while turning the pulley by hand. Check it runs evenly before refitting the cover and its three screws, remembering the longer screw goes back in the front hole. Plug the planer back in and run it unloaded for a minute to confirm the motor and belt are turning together properly before putting it back to work on wood.

Verdict

Of everything on Triton’s TPL180 troubleshooting table, this is one of the few rows with a genuine DIY fix attached. The “No power” and “Motor does not start” rows on the same table route worn carbon brushes and power-tool faults to an authorised Triton service centre — but a broken drive belt is just a belt, and Triton gives you the full replacement procedure rather than deflecting it. A new belt costs a small fraction of a replacement planer, so this is worth fixing yourself rather than a reason to retire the tool.
