The symptom pattern

The saw starts and cuts normally, but the guide bar and chain run dry and get hot during use rather than staying visibly wet with oil. On a chainsaw that’s a genuine wear risk, not just a performance niggle — Einhell’s own troubleshooting table for the GC-PC 1335/1 I lists exactly this as “insufficient chain lubrication (the cutter rail and chain get hot),” with only two possible causes.

What Einhell’s own table says

Section 9 of the manual gives two causes for insufficient chain lubrication: an empty oil tank for the chain, or the oil lubrication entry point on the guide rail having moved or blocked. The remedies are just as short — top up the oil tank, or clean the oil entry hole and groove on the guide rail.

The saw carries two separate reservoirs: a fuel tank for the petrol/oil engine mixture, and a dedicated oil tank that feeds the bar and chain. Einhell’s manual is explicit that “whenever you refill the fuel tank with petrol you must also top up the level of chain oil in the chain oil tank,” and names the oil type directly — “Chain, Bar and Sprocket Oil” — with a plain warning: “never starve the bar and chain of lubricating oil.”

The automatic oiler itself is a toothed-wheel-drive system that speeds up as the engine is accelerated, feeding oil through the bar plate. Its flow rate is set by an adjustment screw on the underside of the saw, but Einhell’s own documentation calls that setting factory-perfect and routes any further adjustment to “your nearest authorized after-sales service outlet” rather than giving an owner a setting procedure — the same treatment the manual gives the carburettor.

Working through it

With the engine switched off, check the oil tank level first — it’s easy to top up fuel and forget the second cap. If the tank is full, clean the oil entry hole and the groove the chain runs in on the guide rail with a proper cleaning tool; a blocked or displaced entry point is the manual’s other named cause. Einhell gives a direct way to confirm the fix worked without guesswork: hold the running saw with the chain over a sheet of paper at full speed for a few seconds, and the oil spray pattern on the paper shows whether the oiler is delivering. If the tank is full, the groove is clear, and the paper test still shows no oil, that’s the point the manual hands to a service outlet rather than the flow-adjustment screw.

Verdict

Both causes Einhell names are free, five-minute checks with the saw switched off, and the paper test gives a clear pass/fail rather than a guess. Don’t reach for the underside adjustment screw before checking the tank and the groove — and if both of those check out clean, Einhell’s own manual says the flow setting is a service-centre job, not an owner-level adjustment. Running the saw dry in the meantime isn’t worth risking: a starved bar and chain run hot and wear faster with every cut.
