ADDITIONAL SAFETY RULES FOR JOINTERS
I AVOID KICKBACKS A kickback occurs when the
workpiece is thrown back by the cuttorhoad toward the
infeed table. Never pass hands directly over the cutterhead.
When a kickback occurs an injury can result. Some ol the
causes of kickback include:
A Dull and improperly adjusted knives.
B. Knots, nails or imperfections in the workpiece.
C. Taking too deep a cut in one pass.
D. Failure to use adequate hold-downs/push blocks
when jointing or surfacing short, thin or narrow
work.
2. IF YOU ARE NOT thoroughly familiar with the opera¬
tion of jointers, obtain advice from your supervisor, instruc¬
tor or other qualified person.
3. MAKE SURE wiring codes and recommended elec-
tncal correction instructions arc followed, and that the
machine is properly grounded.
4. MAKE all adjustments with the power off.
5 MAINTAIN theproper relationship of infeed and outfeed
table surfaces and cutterhead knife path.
6. MAKE SURE the cutterhead is not contacting the
workpiece before turning on the power.
7. KEEP knives sharp and cutterhead and knives free of
all rust and pitch
8. ALWAYS keep hands and fingers away from the blade
when the machine is running.
9. ALWAYS keep cutterhead guard in place when per¬
forming a jointing or planing operation. Check guard opera
tion periodically to make certain that it operates freely.
10 DEFINITIONS OF JOINTING AND PLANING
OPERATIONS:
A Jointing Operations - Jointing cuts or edge jointing
are made to square an edge of a workpieco. The
workpiece is positioned on the jointer with the narrow
edge of the workpiece on tl ic infeed table and the major
flat surface of the workpiece against the fence. The
workpiece is moved from the infeed table across the
cutterhead to the outfeed table.
B. Planing Operations - Planing or surfacing is similar to
the jointing operation except for the position of the
workpiece. For planing, the major flat surface of the
workpieco is placed on the table of the jointer with the
narrow edge of the workpiece against the fence
11 ALWAYS use hold-downs/push blocks for jointing
material less than 3 inches in height or planing material
less than 3 inches thick.
12 . DO NOT perform jointing or planing operations on
material shorter than 10 inches.
13. NEVER perform a planing operation on material wider
than 6 inches.
14. NEVER make a jointing or planing cut deeper than
1 / 8 -
15 SUPPORT the workpiece adequately at all times dur¬
ing operation: maintain control ol the workpiece at all times.
16. DO NOT back the work toward the infeed table. Always
feed workpiece against cutterhead direction of rotation.
17. DO NOT attempt to perform an unfamiliar operation
without study and the use of adequate hold-downs/push
blocks, jigs, fixtures, stops, etc.
18. STOP the machine before removing chips
19. DISCONNECT machine from the power source before 'V*
making repairs.

ELECTRICAL CONNECTIONS
The electrical rating of the DJ 15 6' Jointer is either 115/230 Volt, Single Phase or 200-230/460 Volt Three Phase
Before connecting your machine to an electrical power system, bo sure the motor rating agrees with the electncal system
it is to be connected to. We also recommend that tt 14 wire, fused with a 20 amp. dual element time lag fuse, be used to supply
power to all machines regardless of their electrical rating.
SINGLE PHASE INSTALLATION
If the motor on your machine is wired for 115 Volt, Single
Phase, the power cord is equipped with a plug that has two
Hat. parallel current-carrying prongs and one longer round
or ‘U -shaped, ground prong which requires a mating
3-conductor grounded type receptacle, as shown in Fig. 13.
II the motor on your machine is wired lor 230 Volt. Single
Phase, the power cord is equipped with a plug that has two
Hat. current-carrying prongs in tandem, and one round or
“U"-shaped longer ground prong. I his is used only with the
proper mating 3-conductor grounding type receptacle, as
shown in Fig. 14.
When either the 115 Volt or 230 Volt three prong plug on
your machine is plugged into a grounded 3-conductor
receptacle, the long ground prong on the plug contacts first
so the machine is properly grounded before electricity
reaches if.
WARNING. IN ALL CASES. MAKE CERTAIN THE RE¬
CEPTACLE IN QUESTION IS PROPERLY GROUNDED.
IF YOU ARE NOT SURE. HAVE A CERTIFIED ELEC¬
TRICIAN CHECK THE RECEPTACLE
THREE PHASE INSTALLATION
