Section 1
GENERAL SAFE
WORK PRACTICES
|
|
| 1. |
Avoid wearing loose clothing (including
unfastened aprons and shop coats), long sleeves and ties
which might be caught in moving machinery. |
| 2. |
Never wear gloves of any
kind nor rings or bracelets
around moving machines. |
| 3. |
Safety devices, guards, etc., must
be used on machinery. (Work which cannot be
accomplished with the guards in place must be supervised
by the instructor). |
| 4. |
All adjustments must be made and fasteners secured BEFORE
power is turned on. |
| 5. |
All "special set-ups" must
be checked by instructor before power is turned
on. |
| 6. |
Wrenches and other tools must be removed form
machines before power is turned on. |
| 7. |
Students must not distract attention of those using
machines, likewise students should not let their
attention be diverted while they are operating any
machine. |
| 8. |
If a student finds a machine out of adjustment, he
must immediately report it to the
instructor. |
| 9. |
Remove all loose stock, scraps of
wood or other material from the floor where it might
cause someone to trip and fall into a machine |
| 10. |
Power should always be shut off after a machine
has been used, and no student should start or stop a
machine for another. |
| 11. |
Great care must be taken to see that all lumber is
free from nails, sand, paint or loose knots before being
machined. |
| 12. |
Stock must never be forced into a machine
faster than it will cut. |
| 13. |
Machines should not be used for trivial operations,
especially on small pieces of lumber. Use hand tools. |
| 14. |
Power must be turned off at the main electrical panel
before cleaning machines; changing saw blades, shaper
knives, or making major adjustments or repairs on any
machine. |
| 15. |
Electrical cords on all portable machines must be
disconnected before changes or adjustments are made.
Examples: Changing router cutters, sanding belts, drills,
etc. |
| 16. |
Dull hand tools, saw blades, cutter-head knives,
shaper knives, router cutters, etc. are more hazardous to
use than sharp ones, and should never be used. |
| 17. |
All lumber and plywood must be returned and stored
properly in racks so that it will not fall or be left on
the floor for someone to trip over. |
| 18. |
All clamps must be kept off the floor and returned to
proper storage racks when not in use. When bar clamps
extend beyond furniture, cabinets, etc., which have been
assembled and clamped, rags must be hung over the ends of
the extending clamps. |
| 19. |
All hand tools, machine accessories, etc. must be
kept off the floor and returned to proper storage holders
when not in use. |
| 20. |
Hand tools, portable machines, and other equipment,
when temporarily not in use, must be kept on the benches
at a safe distance from the edge. |
Section 2
RADIAL
SAW
|
|
| 1. |
The radial saw is intended for quantity
cutting only, and must not
be used for sawing short pieces of stock. Use hand
saw. |
| 2. |
Keep hands away from track of the saw at all times. |
| 3. |
When operating the saw, do not force the saw through the stock
faster than it will cut. |
| 4. |
Students must never
attempt to clear away scraps of stock from the track of
the saw with their fingers. If necessary to remove
them, push them away with a stick. |
| 5. |
When sawing wide boards avoid warped
lumber from pinching the saw. Warped stock should be cut slowly
and saw kept cleared by pushing the
saw back and forth until the cut is completed. |
Section 3
JOINTER
|
|
| 1. |
Guards must be in working order and over
the knives at all times while the
jointer is being used for facing and jointing. |
| 2. |
All adjustments of the fence must be
made when the cutter head is not
rotating. |
| 3. |
The jointer must not be used
for stock less than 12 inches long
and 2 inches wide. |
| 4. |
If it is necessary to joint stock less
than 2 inches wide, feather boards
must be clamped in place or other provision made
to hold the work. |
| 5. |
All special set-ups on the jointer must
be inspected by instructor before
power is turned on. |
| 6. |
The end grain of a piece of stock narrower
than 12 inches must never
be run over the jointer. |
| 7. |
When tailing-off long pieces from the
jointer, the helper must not pull
the stock. |
| 8. |
The Oliver jointer must be stopped by
applying brake. |
Section 4
PLANER
|
|
| 1. |
Adjust the planer to take not more than 1/8 inch cut before
stock is fed into it. Stock less than 1/4
inch thick must mot be planed unless supported by a heavy backing board. |
| 2. |
Stock less than 18 inches long should
not be run through the large Oliver planer |
| 3. |
When operating the planer, do not allow hands
to come near the feed rolls. |
| 4. |
Do not attempt to
shift boards after the boards have been gripped by the
feed rolls. This is dangerous as
loose clothing or fingers are apt to be caught between
the board and the planner bed. |
| 5. |
The hood must never be raised
while the planer is running. |
| |
Section 5
CIRCULAR
SAW
|
|
| 1. |
Ripping stock and cross cutting stock
without using the ripping fence or the crosscutting gauge
is extremely dangerous,
and forbidden.
This practice applies also when using the dado-head. |
| 2. |
The saw guard and splitter must
always be used when ripping stock. |
| 3. |
The rip saw blade only should be
used for ripping hardwood. |
| 4. |
The combination saw blade must be
used for cutting plywood. |
| 5. |
The combination or crosscut saw blades
must be used for crosscutting. |
| 6. |
The height of the saw above the table
should be just sufficient to cut cleanly through the
stock. (Approximately 1/8 inch.) |
| 7. |
A push stick must be used when
ripping if there is less than three inches between
the saw and the fence. |
| 8. |
Do not rip
stock less than 18 inches long. |
| 9. |
Wait until the saw has completely
stopped rotating to adjust the fence. |
| 10. |
The rip fence must be clamped
securely in place before ripping. |
| 11. |
The
operator must stand to one side of the
stock when ripping. |
| 12. |
A clearance block must always be used,
and be securely attached to the rip fence, when using it
as a gauge for cutting stock to length. |
| 13. |
Never use fingers to clear away
scraps close to the saw while the saw is in motion.
To remove scraps, push away with a stick about two feet
long. |
| 14. |
Hands should never
cross over the line of the saw and keep
fingers clear. |
| 15. |
The rolling table on the Oliver saw must
be locked when not in use. |
| 16. |
The person tailing-off should support
the stock and not pull it. He should depend on the
operator to push the stock through the saw. |
| 17. |
Lowering pieces of stock over the
circular saw requires a "stop block" to be
clamped to the fence. |
| 18. |
When parts to be machined are large,
making it impossible to clamp a "stop block" to
the fence, the fence must be extended by fastening a long
piece of wood to it and then clamping the "stop
block" to this piece. |
| 19. |
All special set-ups and dado-heads must
be inspected by instructor before power is turned on. |
| |
Section 6
BAND SAW
|
|
| 1. |
The saw guide must be adjusted within
1/4 inch of stock to be cut before
power is turned on. |
| 2. |
Do not allow fingers to come
closer than two inches
from the saw blade when cutting. |
| 3. |
Do not stand at right hand side
of band saw machine. A serious accident might result
if saw blade should break. |
| 4. |
To back the stock out of a long saw cut,
power should first be
turned off and the machine allowed to
come to a dead stop. |
| 5. |
A sharp curve of small radius should not
be cut except with a very narrow band saw blade. |
| 6. |
Cylindrical stock must never be
cut on the band saw unless some type of holder is
used. |
| 7. |
The guide must
not be adjusted while band saw is in motion. |
| 8. |
Thin stock must not be cut on the band saw unless such material is firmly supported by
the ripsaw fence against the downward thrust of the saw. |
| 9. |
If the band saw blade should break while
the machine is in operation, the operator will
immediately shut off power, apply foot brake, keep
clear of saw, and notify instructor. |
| |
Section 7
JIG
SAW
|
|
| 1. |
The saw must be adjusted for proper

begins. |
| |
Section 8
MORTISER
|
|
| 1. |
Adjust the downward travel of the hollow
chisel and the height of the table before power is turned
on, so that the bit at the bottom of its stroke will not
strike the table. |
| 2. |
Stock must be firmly clamped to the
machine before being mortised. |
| 3. |
The stock must be moved sideways the
whole width of the chisel between each cut. End cuts of
the mortise should be made first. |
| 4. |
The stock must not be moved until bit is
clear of the mortise. |
| 5. |
When mortising hardwood, the hollow
chisel must not be forced into the stock faster than it
will cut. |
| |
Section 9
BELT
SANDER (Wysong)
|
|
| 1. |
The table must be adjusted so that the
belt just clears the stock to be sanded. |
| 2. |
The stock to be sanded must be placed
securely against the "stop" |
| 3. |
The fingers must be kept a safe distance
from the edge of the belt. |
| |
Section 10
BELT
SANDER (Delta)
|
|
| 1. |
All adjustments must be properly locked
before the power is turned on. |
| 2. |
The operator should check the sanding
belt to make certain it is tracking properly at the
center of the pulleys. |
| 3. |
Very small pieces of stock or irregular
shaped pieces should not be sanded on the belt sander. |

| 1. |
Never wear loose sleeves, clothing, or
flowing neckties while working on a woodturning lathe. |
| 2. |
Glued-up stock should set at least
overnight before turning. |
| 3. |
Before turning on the power, rotate
every piece of work several times by hand to make certain
it will clear the tool rest and bed. |
| 4. |
Dead centers should be lubricated and
tail stock securely locked for all work between centers.
Live centers are not to be forced into the work by means
of the screw. Use a mallet. |
| 5. |
All stock over 2 inches square must
have the comers chamfered before being turned. |
| 6. |

while work is stationary. When work is round and near the
completed size, it may be clamped while rotating. Be
careful not to catch the caliper between the rotating
stock and tool rest. |
| 10 |
The gouge should never be used for
inside recessed work. |
| 11. |
Center push rods must never be left in
the spindle. |
| 12. |
The live center should be removed and
racked when not in use. |
| 13. |
While sanding in the lathe, see that
the tool rest is either removed or pushed entirely to one
side to prevent the sandpaper from drawing the hand
between the rest and the work. |
| 14. |
Be extremely cautious in selecting the
various operating speeds when turning to prevent the
stock from flying apart. |
| 15. |
A face shield or goggles must be worn
while operating the lathe. |
| |
Section 14

Special permission must be secured from
the instructor before any student may use the shaper. |
| 3. |
All attachments, hold-down clamp,
feather board, and stops must be securely fastened into
position before the machine is started. |
| 4. |
In shaping, the stock must always be
pushed against the rotation of the cutters. |
| 5. |
The stock must not be forced against
the knives faster than they will easily cut away the
waste material. |
| 6. |
Each set-up on the shaper must be
carefully inspected by the instructor before machine is
started. |
| |
Section 15

PRESS
|
|
| 1. |
Before placing the drill or bit in the
drill press chuck, check the speed by starting the motor. |
| |
Use slow speed for large bits, medium
speed for medium size bits, and a faster speed for small
bits or drills.. |
| 2. |
Bits or drills must be securely
fastened in the chuck. |
| 3. |
Very small and very large parts to be
drilled must be clamped securely to the drill press table |
| 4. |
When boring holes at an angle, clamp
the piece securely to the drill press table, and use a
forstner bit or twist drill. |
| 5. |
Keep hands clear of the line of travel
of the bit or drill. |
| 6. |
When setting up the drill press, make
certain that the bit or drill does not strike the table.
Use a scrap piece of wood to back-up the part to be

| |
Section 18
HIGH FREQUENCY WELDER
|
|
| |
This is a high frequency welder used
for thermosetting of resin adhesives. It brings radio
frequency energy in concentrated quantities form the
frequency generator unit of the machine through a coaxial
transmission line to the gun (hand piece). |
| |
Energy is generated of sufficient force
to completely polymerize (cure) glued joints in three or
four seconds. The normal time for glued joints to cure
(dry out) at room temperature is twelve hours. |
| |
CONSEQUENTLY: |
| 1. |
Keep hands away from electrodes when
power is flowing. |
| 2. |
Keep gun (hand piece) away from metal
surfaced tables, clamps or other metal objects to prevent
arcing. |
| 3. |
It is well to be aware that radio
frequency energy cause severe burns - originating
internally and projecting outwardly. Therefore operate
this machine with extreme caution. |
