Hammers
• Never strike a hammer against a hardened object, such
as another hammer.
• Always grasp a hammer handle firmly, close to the end.
• Strike the object with the full face of the hammer.
• Never work with a hammer which has a loose head.
• Discard hammer if face is chipped or mushroomed.
• Wear approved eye protection when using striking tools.
• Protect bystanders with approved eye protection.
Punches/Chisels
• Never use a punch or chisel with a chipped or mush-
roomed end; dress mushroomed chisels and punches with
a file.
• Hold a chisel or a punch with a tool holder if possible.
• When using a chisel on a small piece, clamp the piece
firmly in a vise and chip toward the stationary jaw.
• Wear approved eye protection when using these tools.
• Protect bystanders with approved eye protection.
Screwdrivers
• Do not use a screwdriver for prying, punching, chiseling,
scoring or scraping.
• Use the right type of screwdriver for the job; match the tip
to the fastener.
• Do not interchange POZIDRIV, PHILLIPS or REED AND
PRINCE screwdrivers.
• Screwdriver handles are not intended to act as insulation.
Do not use on live electrical circuits.
• Do not use a screwdriver with rounded edges because it
will slip. Redress with a file.
Ratchets and Handles
• Periodically clean and lubricate ratchet mechanisms with
a light grade oil. Do not replace parts individually; ratchets
should be rebuilt with the entire contents of service kit.
• Never hammer or put a pipe extension on a ratchet or
handle for added leverage.
• Always support the ratchet head when using socket
extensions, but do not put your hand on the head or you
may interfere with the action of its reversing mechanism.
• When breaking loose a fastener, apply a small amount of
pressure as a test to be sure the ratchet's gear wheel is
engaged with the pawl.
Sockets
• Never use hand sockets on power or impact wrenches.
• Select the right size socket for the job.
• Never cock any wrench or socket.
• Select only impact sockets for use with air or electric
impact wrenches.
• Replace sockets showing cracks or wear.
• Keep sockets clean.
• Always use approved eye protection when using power
or impact sockets.
Storage Units
• Do not open more than one loaded drawer at a time. Close
each drawer before opening up another.
• Close lids and lock drawers and doors before moving
storage units.
• Do not pull on a tool cabinet; push it in front of you.
• Set the brakes on the locking casters after the cabinet has
been rolled to your workspace.
