Proper auxiliary chain oiling results in greater chain life and increased production. The Auxiliary Oiler Kit from Granberg consists of a reservoir tank, mounting bracket, clamps, valves and tubing. The Auxiliary Oiler Kit attaches directly to the Alaskan Mill Mk III in minutes and is recommended for projects where a single powerhead is used with guide bars exceeding 36?, or where the timber being milled is seasoned or hard. The Auxiliary Oiler Kit delivers supplementary oiling directly to the guide bar and chain. For long bars.
