OWNER'S MANUAL
(For models manufactured since 05/23)

This manual provides critical safety instructions on the proper setup,
operation, maintenance, and service of this machine/tool. Save this
document, refer to it often, and use it to instruct other operators.
Failure to read, understand and follow the instructions in this manual
may result in fire or serious personal injury—including amputation,
electrocution, or death.
The owner of this machine/tool is solely responsible for its safe use.
This responsibility includes but is not limited to proper installation in
a safe environment, personnel training and usage authorization,
proper inspection and maintenance, manual availability and compre-
hension, application of safety devices, cutting/sanding/grinding tool
integrity, and the usage of personal protective equipment.
The manufacturer will not be held liable for injury or property damage
from negligence, improper training, machine modifications or misuse.
Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement and other masonry products.
• 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 equip-
ment, such as those dust masks that are specially designed to filter
out microscopic particles.

Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety pre-
cautions are overlooked or ignored, serious
personal injury may occur.
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.

Controls &
Components
Refer to Figures 1–4and the following descrip-
tions to become familiar with the basic controls
and components of this machine. Understanding
these items and how they work will help you
understand the rest of the manual and stay safe
when operating this machine.
D. Fence: Guides workpiece as it moves across
cutterhead and determines angle of cut.
E. Infeed Table Lock: Loosens to allow adjust-
ment of infeed table height; tightens to secure
infeed table.
F. Infeed Table: Supports workpiece before it
reaches cutterhead. Position of infeed table
relative to cutterhead determines depth of
cut.
G. Infeed Table Adjustment Lever:Adjusts
height of infeed table (when infeed table lock
is loosened).
H. Depth-of-Cut Scale: Indicates cutting depth
of a single pass.
A. POWER Switch w/Disabling Key: Turns
power to machine ON or OFF. Remove yel-
low/orange key to disable switch.
B. START Button: Turns motor ON.
C. STOP Button: Turns motor OFF.

I. Fence Tilt Handle:Tilts fence throughout its
range of motion from 45°–135° (45° outward).
J. 45° Fence Stop: Stops fence at 45°.
K. 90° Fence Stop: When engaged, stops
fence at 90°.
L. 135° Fence Stop: Stops fence at 135° (45°
outward).
M. Fence Tilt Lock: Secures fence tilt setting at
desired angle.
Note: Even when fence is resting against
fence stops, tilt lock must be tightened before
starting machine.
N. Fence Lock: Loosens to allow adjustment of
fence position along width of tables; tightens
to secure fence.
O. Outfeed Table: Supports workpiece after
it passes over cutterhead. For safety and
best results, outfeed table must be properly
adjusted relative to cutterhead inserts before
ANY operations (see Page 48 for addi-
tional details).
P. Cutterhead Guard: Covers cutterhead
until pushed out of the way by workpiece
during operation. When workpiece leaves
cutterhead, guard springs back to its starting
position.
Q. Outfeed Table Lock: Loosens to allow
adjustment of outfeed table height; tightens
to secure outfeed table.
R. Outfeed Table Adjustment Lever:
Adjusts height of outfeed table. Typically
only used when setting outfeed table even
with cutterhead inserts or when servicing
cutterhead.

ELECTRICAL EQUIPMENT INJURY RISKS.
You can be shocked, burned, or killed by touching
live electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
DISCONNECT POWER FIRST.
Always discon-
nect machine from power supply BEFORE mak-
ing adjustments, changing tooling, or servicing
machine. This prevents an injury risk from unin-
tended startup or contact with live electrical com-
ponents.
EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.
OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.
TRAINED OPERATORS ONLY. Untrained oper-
ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis-
connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make your workshop kid proof!
DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin-
ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.
For Your Own Safety, Read Instruction
Manual Before Operating This Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of impor-
tance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgment.
Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
Alerts the user to useful information about proper operation of the
machine to avoid machine damage.
