USING A HAND SCREW CLAMP
CAUTION
Use only on wood.
Examine material to be clamped and select a clamp
which will span across the work.
1
Open the clamp jaws (1) and place the work
between the jaws. Keep jaws parallel. Use rawhide
or soft leather to protect highly polished surface.
2
Tighten operating screws (2) making sure the clamp
jaws remain parallel. Be sure jaws fit firmly on work.
Properly clamped work will form a square.
CAUTION
Make sure vise jaws remain parallel to
edges of work.
CARE OF C-CLAMPS
Clean threads and swivel with a rag, and lubricate with a
light coat of oil.
Store on a rack, on pins, or in a tool box.
For long storage periods, apply a rust-preventive
compound.
CARE OF HAND SCREW CLAMPS
Lubricate screws with a few drops of light oil. Apply light
coat of linseed oil to wood surfaces.
Store clamps on racks, pins, or carefully place them in
your tool box. Wipe clamps off with a rag before storing.
