Hitachi hammers use 30wt non detergent oil. But you can use lighter oil in cold climate. If too much oil accumulates in hammer, it may just come out bit retainer or build-up inside gun. Oil enters the hammer by wick process, of wick is missing oil will enter too quickly. If your brand label is glued on, you may have a hitachi copy from china (most hitachi labels are rivited on). China hammers may use different oil.
