WA600-6 tech manual shows R134A charge to be 850 grams (approx 30 ounces). Komatsu A/C systems always seem to take less than I would think.

90% of komatsu's I've charged we're 2.2 lbs, that's what always seems to come out from factory. Nonetheless should be fine with that amount. Generally unless you change your compressor, 1 oz of oil per lb of r134a
