by hand. If bits are stuck, remove and clean packed soil from bit block.
• For best results, use retaining clip loading and removing tool and a knock-out bar included
with saw to remove and reinsert bits.
• Carbide bits are recommended for cutting abrasive material, such as sandstone or frozen
sands or gravels.
