Sorry, we couldn't find any existing installation instruction that matched.
Safety Lock Key was missing from new product.
Makita did not have the part available. Purchased from PartSelect. Took two months to arrive, but simply installed the key. Mower works great. Makita is also sending a key, but having a spare will be good.
