We are currently experiencing substantial delays with Hitachi/HiKOKI and Metabo spare parts due to the two brands merging warehouse. At this moment in time we are unable to provide confirmed delivery dates on out of stock parts, for any urgent requirements please contact us prior to ordering.
Genuine Hitachi oil-tank cover (part no. 6686138) — a hard plastic replacement cap for the chain‑oil reservoir that protects the tank opening from debris and helps prevent oil leaks while restoring proper lubrication flow to the bar and chain.
Fits a range of Hitachi/HiKOKI pole‑saw and chainsaw models, for example CG‑PS / CG‑PSB), SF‑PE, TPS‑200H / TPS‑210 , and CS25EPB, CS27EPA / CS27EPAP and TCS27EPA / TCS-3350S.
Item 668138 pairs with the oil‑tank gasket and O‑ring items in the original parts list (see nearby part numbers such as 6699567 and 6695661). Installation is straightforward — the cover seats over the reservoir opening and secures in the same place as the original Hitachi piece so you can get your saw back to service quickly.
