Webb WEPCS18 18" (46cm) 50cc Petrol Chainsaw
The WEPCS18 steps up from the WEPCS16 with a larger 50cc engine and an 18" (46cm) bar — more power and more reach for larger trees, bigger logs, and heavier garden clearance work where the 45cc model would be working harder. The EURO-5 compliant 2-stroke delivers the extra torque needed to maintain chain speed through larger diameter timber without the engine labouring.
At 4.86kg without bar and chain it's actually slightly lighter than the WEPCS16 despite the larger engine and longer bar — a notable figure for a 50cc petrol saw that makes it comfortable to handle for extended periods and at awkward angles. The 18" bar with 72-link 0.325" chain covers the kind of felling and log work that a 16" bar would manage but with more confidence on larger material.
Automatic chain oiling with a 260ml tank keeps maintenance interruptions to a minimum, and the ergonomic handles with intuitive controls make it accessible for less experienced users as well as confident operators.
Backed by a 3-year warranty with UK-based customer support.
