He should only use cold water but not hot water with silver vessels as it blackens them.

He should only use hot water with copper vessels but not fire, as it wears them down.

He may use rakes and axes on soft things but not on hard things.

He may use a rake to mix the mud and then he should rinse it and return it to its place.

He may chop wood with an axe but he may not chop thin date palm nor olive tree wood (as they are hard and damage the axe).

The same care instructions that apply to a found item apply to a deposited item.

If one deposited a garment with a friend, he should shake it once in 30 days and if it involves a lot of work, he may ask for payment from the owner.

(Mishnah): What is considered to be lost? If he found a donkey or a cow grazing in the road, they are not lost. If he found a donkey and its load overturned or a cow running between the vines, they are lost.

If he returned it and it escaped and he returned it and it again escapred, even four or five times, he must still return it, as the pasuk states (Devarim 22, 1), "hashev teshivem - you shall surely return it'' - (the double wording indicated that he must return it even multiple times).

If the finder cannot do a selah's worth of work whilst taking care of the lost item, he cannot tell the loser to return him a selah - rather, he must merely pay him for that time like a manual laborer.

If there is a Beis Din in that locality, he may make a stipulation in front of the Beis Din. If there is no Beis Din to be able to make a stipulation, he may leave the lost item and take care of his own business (in order to avoid a financial loss).
