approved, properly fitting face mask or respirator when using such tools.
GENERAL SAFETY RULES
READ AND UNDERSTAND ALL WARNINGS AND OPERATING INSTRUCTIONS BEFORE
USING THIS EQUIPMENT. Failure to follow all instructions listed below, may result in electric shock,
fire, and/or serious personal injury or property damage.
IMPORTANT SAFETY INSTRUCTIONS
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. For additional information please visit our website www

MANUAL BEFORE OPERATING THE MACHINE.
Learning the machine’s application, limitations, and
specific hazards will greatly minimize the possibility of
accidents and injury.
2. WEAR EYE PROTECTION. ALWAYS USE SAFETY
GLASSES. Also use face or dust mask if cutting
operation is dusty. Everyday eyeglasses are NOT safety
glasses. USE CERTIFIED SAFETY EQUIPMENT. Eye
protection equipment should comply with ANSI Z87.1
standards, hearing equipment should comply with
ANSI S3.19 standards, and dust mask protection
should comply with MSHA/NIOSH certified respirator
standards. Splinters, air-borne debris, and dust can
cause irritation, injury, and/or illness.
3. WEAR PROPER APPAREL. Do not wear loose
clothing, gloves, neckties, rings, bracelets, or other
jewelry which may get caught in moving parts. Nonslip
footwear is recommended. Wear protective hair
covering to contain long hair.
4. DO NOT USE THE MACHINE IN A DANGEROUS
ENVIRONMENT. The use of power tools in damp or
wet locations or in rain can cause shock or
electrocution. Keep your work area well-lit to prevent
tripping or placing arms, hands, and fingers in danger.

potentially dangerous environment. Children and visitors can
be injured.
9. REDUCE THE RISK OF UNINTENTIONAL STARTING.
Make sure that the switch is in the “OFF” position
before plugging in the power cord. In the event of a
power failure, move the switch to the “OFF” position.
An accidental start-up can cause injury.
10. USE THE GUARDS. Check to see that all guards are in
place, secured, and working correctly to prevent injury.
11. REMOVE ADJUSTING KEYS AND WRENCHES
BEFORE STARTING THE MACHINE. Tools, scrap
pieces, and other debris can be thrown at high speed,
causing injury.
12. USE THE RIGHT MACHINE. Don’t force a machine or
an attachment to do a job for which it was not
designed. Damage to the machine and/or injury may
result.
13. USE RECOMMENDED ACCESSORIES. The use of
accessories and attachments not recommended by
Delta may cause damage to the machine or injury to the
user.
14. USE THE PROPER EXTENSION CORD. Make sure
your extension cord is in good condition. When using
an extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized
cord will cause a drop in line voltage, resulting in loss of
power and overheating. See the Extension Cord Chart
for the correct size depending on the cord length and
nameplate ampere rating. If in doubt, use the next
heavier gauge. The smaller the gauge number, the
heavier the cord.
15. SECURE THE WORKPIECE. Use clamps or a vise to hold
the workpiece when practical. Loss of control of a
workpiece can cause injury.
16. FEED THE WORKPIECE AGAINST THE DIRECTION OF
THE ROTATION OF THE BLADE, CUTTER, OR ABRASIVE
SURFACE. Feeding it from the other direction will cause
the workpiece to be thrown out at high speed.
17. DON’T FORCE THE WORKPIECE ON THE MACHINE.
Damage to the machine and/or injury may result.
18. DON’T OVERREACH. Loss of balance can make you
fall into a working machine, causing injury.
19. NEVER STAND ON THE MACHINE. Injury could occur if the
tool tips, or if you accidentally contact the cutting tool.
20. NEVER LEAVE THE MACHINE RUNNING UNATTENDED.
TURN THE POWER OFF. Don’t leave the machine until it
comes to a complete stop. A child or visitor could be injured.
21. TURN THE MACHINE “OFF”, AND DISCONNECT THE

1. All grounded, cord-connected machines:
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 machine is
equipped with an electric cord having an equipmentgrounding 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 equipmentgrounding 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 machine is
properly grounded.
Use only 3-wire extension cords that have 3-prong
grounding type plugs and matching 3-conductor
receptacles that accept the machine’s plug, as shown in
Fig. A.
Repair or replace damaged or worn cord immediately.

DEFINITIONS OF JOINTING AND PLANING OPERATIONS
Fig. 2
Fig. 3
JOINTING OPERATIONS – Jointing cuts or edge jointing is the simplest and most common operation which can be
done on the jointer and these cuts are made to square an edge of a workpiece. The fence is square with the table and
the depth of cut is approximately 1/8 inch. The workpiece is positioned on the jointer with the narrow edge of the
workpiece on the infeed table and the major flat surface of the workpiece against the fence, as shown in Fig. 2. The
workpiece is moved from the infeed table, across the cutterhead to the outfeed table.
PLANING OPERATIONS – Planing or surfacing is identical to the jointing operation except for the position of the
workpiece. For planing, the major flat surface of the workpiece is placed on the infeed table of the jointer with the narrow
edge of the workpiece against the fence, as shown in Fig. 3. The workpiece is moved from the infeed table, across the
cutterhead to the outfeed table establishing a flat surface on the workpiece. Always use push blocks when performing
planing operations and NEVER pass your hands directly over the cutterhead.
Never pass your hands directly over the cutterhea. Use push blocks to feed the workpiece
whenever possible.
The hand over the outfeed table presses the work down so that the newly-formed surface will make perfect contact with
the table. The hand over the infeed table (usually the right hand) exerts no downward pressure, but simply advances
the work to the cutterhead. Both hands exert pressure to keep the work in contact with the fence.
