GENERAL SAFETY RULES
Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there
are certain hazards involved with the operation of the product. Using the machine with respect and caution will
considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored,
personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards,
goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won’t make
up for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop.
If a procedure feels dangerous, don’t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your
personal safety is your responsibility.
This machine was designed for certain applications only. Delta Machinery strongly recommends that this machine not
be modified and/or used for any application other than that for which it was designed. If you have any questions relative
to a particular application, DO NOT use the machine until you have first contacted Delta to determine if it can or should
be performed on the product.

moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect its
operation. A guard or other part that is damaged should be
properly repaired or replaced.
20. DIRECTION OF FEED. Feed work into a blade or
cutter against the direction of rotation of the blade or cutter
only.
21. NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN POWER OFF. Don’t leave tool until it comes to a
complete stop.
22. STAY ALERT, WATCH WHAT YOU ARE DOING, AND
USE COMMON SENSE WHEN OPERATING A POWER
TOOL. DO NOT USE TOOL WHILE TIRED OR UNDER
THE INFLUENCE OF DRUGS, ALCOHOL, OR
MEDICATION. A moment of inattention while operating
power tools may result in serious personal injury.
23. MAKE SURE TOOL IS DISCONNECTED FROM
POWER SUPPLY while motor is being mounted,
connected or reconnected.
24. THE DUST GENERATED by certain woods and wood
products can be injurious to your health. Always operate
machinery in well ventilated areas and provide for proper
dust removal. Use wood dust collection systems whenever
possible.
25. WARNING: SOME DUST CREATED BY
POWER SANDING, SAWING, GRINDING, DRILLING,
AND OTHER CONSTRUCTION ACTIVITIES contains
chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals
are:
· lead from lead-based paints,
· crystalline silica from bricks and cement and other
masonry products, and
· arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure
to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those
dust masks that are specially designed to filter out
microscopic particles.
SAVE THESE INSTRUCTIONS.
Refer to them often and use them to instruct others.

1. All grounded, cord-connected tools:
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped with
an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be
plugged into a matching outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided - if it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding
conductor can result in risk of electric shock. The
conductor with insulation having an outer surface that is
green with or without yellow stripes is the equipment-
grounding conductor. If repair or replacement of the
electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if
the grounding instructions are not completely understood,
or if in doubt as to whether the tool is properly grounded.

REMOVING “HEELING”
IN SAW BLADE CUT
Even though the cutting-head travel may be perfectly
aligned at 90 degrees to the fence, the blade itself may
not be 90 degrees or square with the fence, as shown in
Fig. 37. This condition is known as “heeling.”
To check and adjust, proceed as follows:
1. DISCONNECT TOOL FROM POWER SOURCE.
2. Install saw blade without guard.
3. Replace the fence with a flat piece of 3/4″wood (A)
Fig. 38, at least 5″high. Tighten table board clamps.
4. Place three identical pieces of wood (B) Fig. 38, on
the table and lay a framing square on them so that the
short arm is flush against the fence and the long arm is
against the blade as shown. Be sure square is between
the teeth of the blade.
5. If the blade is not parallel to the square, an
adjustment is necessary. Release the yoke clamp handle
(C) Fig. 39, and slightly loosen two hex head screws (D).
Swivel the yoke until the blade is parallel with the square
and tighten yoke clamp handle (C). Then tighten two hex
screws (D) Fig. 39.
CHECKING AND ADJUSTING

1. DISCONNECT TOOL FROM POWER SOURCE.USE
ONLY 10″″BLADES WITH 5/8″″ARBOR HOLES AND
RATED FOR 5000 RPM OR HIGHER.
2. Assemble the inside (thick) arbor flange (A) Fig. 44,
onto the arbor shaft with the recessed side of flange (A)
facing out.
3. With the blade guard (B) Fig. 45, in the left hand,
insert saw blade (C) into the blade guard (B) and onto
the arbor shaft.
4. Assemble the outside (thin) blade flange (D) Fig. 45,
with the recessed side of flange (D) facing in and arbor
nut (E) onto the arbor shaft. NOTE: ARBOR NUT (E)
FIG. 45, HAS A LEFT HAND THREAD.
5. Lift cam (F) Fig. 46, and assemble blade guard (B)
onto cutting-head assembly. NOTE: MAKE CERTAIN
TONGUE ON GUARD SEATS INTO GROOVE OF
CUTTING-HEAD.
6. Rotate blade guard (B) Fig. 47, to the rear and
tighten arbor nut (E) using two wrenches (G) supplied.
7. Rotate blade guard (B) Fig. 46, to the horizontal
position and tighten clamp knob (H). IMPORTANT:
CLAMP KNOB (H) FIG. 46, MUST BE TIGHT AND
BLADE GUARD SECURE DURING OPERATION.
NOTE: The lower retractable blade guard provides
operator protection in an axial direction to the saw
blade. Care must be taken to eliminate potential hazards
of the lower blade guard.
A) KEEP YOUR HANDS AWAY FROM THE
GUARD. As the blade cuts, the guard will lift
and leave part of the blade exposed.
B) SHUT OFF POWER BEFORE FREEING A
JAMMED LOWER GUARD. The guard can get
jammed in previous kerfs in table or fence.
Always anticipate the path of the guard.
C) USE CAUTION when making bevel cuts to be
sure the lower guard is never pinched towards
the blade.
D) THE LOWER GUARD CAN JAM AGAINST
THE FENCE DURING NARROW IN-RIPS.
Should the guard jam against the fence, dis-
connect the saw from power, wait for the blade
to stop, then lift the blade guard and rest it on
top of the fence.

ADJUSTING BALL
BEARINGS AGAINST TRACK
The cutting-head (C) Fig. 61, is suspended from four
pre-loaded, lubricated, shielded ball bearings, two of
which are on fixed shafts at (A) , and two on adjustable
shafts at (B). NOTE: CUTTING-HEAD (C) FIG. 61, IS
REMOVED FROM TRACK ARM FOR ILLUSTRATION
PURPOSES ONLY. DO NOT REMOVE CUTTING-HEAD
FROM TRACK ARM!
After extended use, wear may develop in the track arm,
causing “play” between the ball bearings and the track.
The ball bearings must ride smoothly and evenly in the
channels of the track arm. Adjustment to the two
bearings on adjustable shafts can be made as follows:
1. DISCONNECT TOOL FROM POWER SOURCE.
2. Remove plastic plug (D) Fig. 62, from the top of
track arm (E).
3. Slide cutting-head (C) Fig. 63, until one of the ad-
justable bearings (B) Fig. 60, are visible through hole (G)
Figs. 62 and 63.
4. Using a 1/2″socket, extension, and ratchet (H) Fig.
63, through hole (G) in track arm, slightly loosen hex nut
on adjustable shaft (B) Fig. 61, approximately 1/8 turn.
Repeat procedure for other bearing.

POSITION TO PREVENT UNAUTHORIZED USE. This
can be done by inserting a padlock (D) Fig. 57, through
the holes in switch plate (B) and handle (C) as shown.
Padlock (D) Fig. 57, is available as an accessory.
MOTOR
Your Delta Radial Arm Saw is equipped with a dual
voltage motor capable of 120 volt, single phase
operation or 240 volt, single phase operation. The motor
on your saw is shipped from the factory wired for 120
volt operation. The motor has a built in brake which
automatically stops the blade within seconds after
turning off the saw or when power is lost.
