Scope of Manual

This manual helps the reader understand the machine, how to prepare it for operation, how to control

it during operation, and how to keep it in good working condition. We assume the reader has a basic

understanding of how to operate this type of machine, but that the reader is not familiar with the

controls and adjustments of this specific model. As with all machinery of this nature, learning the

nuances of operation is a process that happens through training and experience. If you are not an

experienced operator of this type of machinery, read through this entire manual, then learn more

from an experienced operator, schooling, or research before attempting operations. Following this

advice will help you avoid serious personal injury and get the best results from your work.

Manual Feedback

We've made every effort to be accurate when documenting this machine. However, errors sometimes

happen or the machine design changes after the documentation process—so

the manual may not

exactly match your machine.

If a difference between the manual and machine leaves you in doubt,

contact our

customer service for clarification.

We highly value customer feedback on our manuals. If you have a moment, please share your

experience using this manual. What did you like about it? Is there anything you would change to

make it better? Did it meet your expectations for clarity, professionalism, and ease-of-use?

INTRODUCTION

Description of Controls

& Components

Refer to Figures 1–8 and the following

descriptions to become familiar with the basic

controls and components used to operate this

machine.

Control Panel

A. Master Power Key Switch: Turns incoming

power ON and OFF. Requires key.

B. ON Button: Turns motor ON when pressed.

C. OFF Button: Turns motor OFF when

pressed. Motor will not start until switch is

reset. Twist clockwise to reset.

Figure 1. Control panel.Control panel.

To reduce the risk of

serious injury when using

this machine, read and

understand this entire

manual before beginning any

operations.

Guide Post

D. Guide Post Handwheel: Adjusts height of

guide post above workpiece, using a rack-

and-pinion system.

E. Guide Post w/Scale: Houses upper blade

guides and support bearing, and shields

operator from upper portion of blade. Adjusts

up or down as necessary to position upper

blade guides/support bearing as close as

possible to workpiece for maximum cutting

accuracy and minimum blade exposure to

operator. Scale on side of guide post indicates

height of upper blade guide above table.

F. Upper Blade Guide & Support Bearing:

Supports blade above workpiece during

operations.

G. Guide Post Lock Knob: Secures guide post

position after adjustment.

Model SB1123 INTRODUCTION

Table Tilt

H. Table Tilt Lock Lever: Secures table tilt

position on trunnion. Must be loosened

before table tilt can be adjusted.

I. Trunnion w/Table Tilt Scale: Functions as a

tilting base for table. Graduated in degrees

from 5° left – 45° right for setting bevel angle.

J. Table Tilt Indicator: Shows table tilt angle.

K. Table Tilt Handwheel: Adjusts angle of table

tilt using a rack-and-pinion system.

Q. Lower Wheel Adjustment Hub: Adjusts

position of lower wheel to upper wheel if

coplanar adjustments become necessary

(refer to Page 65).

Note: The wheels are factory-set to be

coplanar, so we strongly recommend that

you avoid making adjustments here unless it

becomes absolutely necessary.

Lower Wheel Adjustment

L. Foot Brake: When pedal is pressed, brake

shoe physically stops blade wheels, and limit

switch electronically turns motor OFF.

IMPORTANT: After the foot brake is pressed,

the machine can be restarted by pressing the

ON button. The OFF button does not have to

be reset.

Foot Brake

Fence & Miter Gauge

M. Rip Fence: Used for ripping. Distance from

blade determines width of cut.

N. Miter Gauge Lock Knob: Secures angle

position of miter gauge.

O. Miter Gauge: Typically used for cross cuts.

Can be adjusted from 0°–60° left or right,

and has stops at 45°L, 0°, and 45°R.

P. Fence Lock Handle: Secures fence position.

INTRODUCTION

R. Blade Tension Scale: Displays blade tension

using numbers 0–38. For reference purposes

only—after you have found the proper

tension for the blade installed.

S. Blade Tension Handwheel: Increases/

decreases blade tension (refer to Page 27).

Blade Tension & Tracking

T. Blade Tracking Window: Allows monitoring/

adjustment of blade tracking without

requiring wheel cover to be open (refer to

Page 22).

U. Tracking Control Lock Lever: Secures position

of blade tracking control knob.

V. Blade Tension Quick-Release Lever: Quickly

releases blade tension to speed up blade

changes and prevent unnecessary stretching

of blade and wear on saw components when

not in use. Move clockwise to release blade

tension; move counterclockwise to tension

blade; and position downward to partially

tension blade when tracking. To prolong life

of blade, always release blade tension when

saw is not in use.

W. Tracking Control Knob: Adjusts tilt position

of upper wheel to set/control blade tracking

(refer to Page 22).

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 precautions 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 indi-

vidual working conditions. Use this and other

machinery with caution and respect. Failure to

do so may result in serious personal injury or

property damage.

Model SB1123 SAFETY

Understanding Risks of Machinery

Operating all machinery and machining equipment can be dangerous or relatively safe depending

on how it is installed and maintained, and the operator's experience, common sense, risk awareness,

working conditions, and use of personal protective equipment (safety glasses, respirators, etc.).

The owner of this machinery or equipment is ultimately responsible for its safe use. This

responsibility includes proper installation in a safe environment, personnel training and usage

authorization, regular inspection and maintenance, manual availability and comprehension,

application of safety devices, integrity of cutting tools or accessories, and the usage of approved

personal protective equipment by all operators and bystanders.

The manufacturer of this machinery or equipment will not be held liable for injury or property

damage from negligence, improper training, machine modiﬁcations, or misuse. Failure to read,

understand, and follow the manual and safety labels may result in serious personal injury, including

amputation, broken bones, electrocution, or death.

The signals used in this manual to identify hazard levels are as follows:

Death or catastrophic

harm WILL occur.

Moderate injury or ﬁre

MAY occur.

Death or catastrophic

harm COULD occur.

Machine or property

damage may occur.

Basic Machine Safety

Owner’s Manual: All machinery and machining

equipment presents serious injury hazards

to untrained users. To reduce the risk of

injury, anyone who uses THIS item MUST

read and understand this entire manual

before starting.

Personal Protective Equipment: Operating or

servicing this item may expose the user

to ﬂying debris, dust, smoke, dangerous

chemicals, or loud noises. These hazards

can result in eye injury, blindness, long-

term respiratory damage, poisoning,

cancer, reproductive harm or hearing loss.

Reduce your risks from these hazards

by wearing approved eye protection,

respirator, gloves, or hearing protection.

Trained/Supervised Operators Only: Untrained

users can seriously injure themselves

or bystanders. Only allow trained and

properly supervised personnel to operate

this item. Make sure safe operation

instructions are clearly understood. If

electrically powered, use padlocks and

master switches, and remove start switch

keys to prevent unauthorized use or

accidental starting.

Guards/Covers: Accidental contact with

moving parts during operation may cause

severe entanglement, impact, cutting,

or crushing injuries. Reduce this risk by

keeping any included guards/covers/doors

installed, fully functional, and positioned

for maximum protection.
