1.
Keep each tool in its proper stowage place
2.

A4. Machinists' hammers are used on metal and machinery. Soft-faced hammers
are used when there is a danger of damaging the surface of the work, such as
when pounding on a machined surface. Mallets are used to drive wooden-
handled chisels, gouges, and wooden pins. Short-handled sledges are used to
drive driftpins, large nails, and to strike cold chisels and small hand-held rock
drills. Long-handled sledges are used break rock and concrete, to drive spikes
or stakes, and to strike rock drills and chisels. Claw hammers are used for
carpentry work.
A5. Striking tools should be kept clean and free of oil. The heads should be dressed
to remove any battered edges. A light film of oil should be kept on mallets to
maintain a little moisture in the head. Hammer handles should be kept tight.
A6. Do not use a hammer handle for bumping parts in assembly, and never use it as
a pry bar. Do not strike a hardened steel surface with a steel hammer.
