About This Machine

Capabilities

This metal cutting bandsaw uses a gravity-fed

blade to make straight cuts through workpieces

that are clamped in a vise. Since the workpiece is

secured and remains stationary while the blade

lowers automatically, accuracy and operator

safety are maximized.

The vise on the Model SB1020 is capable of

holding rectangular stock up to 9" x 12" and

round stock up to 10".

After a cut is complete, the OFF switch is

triggered and the motor automatically turns off.

Features

In addition to its capabilities, the Model SB1020

has several features to increase versatility and

efﬁciency.

The headstock can be rotated to make angled

cuts from -45°–60° while variable blade speeds

ensure that the proper cutting speed is available

for a variety of workpiece sizes and materials.

Both the downfeed rate and pressure are

adjustable for ﬁne-tuning each cutting operation

and an adjustable auto-OFF power switch

maximizes safety and minimizes energy use by

turning the machine off at the end of every cut.

A ﬂood coolant system, comprised of a coolant

tank and pump in the machine base and an

adjustable nozzle at the blade provide adequate

coolant for optimum cutting efﬁciency and blade

life.

A storage compartment in the cabinet base

provides a convenient location for keeping spare

blades or other accessories and the transport

handle makes moving the machine easy.

For Machines Mfg. Since 8/09

Model SB1020 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 deﬁned 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.

for maximum protection.

For Machines Mfg. Since 8/09 Model SB1020

-7-

SAFETY

5. Entanglement: Loose clothing, gloves,

neckties, jewelry or long hair may

get caught in moving parts, causing

entanglement, amputation, crushing,

or strangulation. Reduce this risk by

removing/securing these items so they

cannot contact moving parts.

6. Mental Alertness: Operating this item

with reduced mental alertness increases

the risk of accidental injury. Do not let a

temporary influence or distraction lead to a

permanent disability! Never operate when

under the influence of drugs/alcohol, when

tired, or otherwise distracted.

7. Safe Environment: Operating electrically

powered equipment in a wet environment

may result in electrocution; operating near

highly ﬂammable materials may result in a

ﬁre or explosion. Only operate this item in

a dry location that is free from ﬂammable

materials.

8. Electrical Connection: With electically

powered equipment, improper connections

to the power source may result in

electrocution or fire. Always adhere to all

electrical requirements and applicable

codes when connecting to the power source.

Have all work inspected by a qualified

electrician to minimize risk.

9. Disconnect Power: Adjusting or servicing

electrically powered equipment while it

is connected to the power source greatly

increases the risk of injury from accidental

startup. Always disconnect power

BEFORE any service or adjustments,

including changing blades or other tooling.

10. Secure Workpiece/Tooling: Loose

workpieces, cutting tools, or rotating

spindles can become dangerous projectiles

if not secured or if they hit another object

during operation. Reduce the risk of this

hazard by verifying that all fastening

devices are properly secured and items

attached to spindles have enough clearance

to safely rotate.

11. Chuck Keys or Adjusting Tools: Tools used

to adjust spindles, chucks, or any moving/

rotating parts will become dangerous

projectiles if left in place when the machine

is started. Reduce this risk by developing

the habit of always removing these tools

immediately after using them.

12. Work Area: Clutter and dark shadows

increase the risks of accidental injury.

Only operate this item in a clean, non-

glaring, and well-lighted work area.

13. Properly Functioning Equipment: Poorly

maintained, damaged, or malfunctioning

15. Health Hazards: Certain cutting fluids

and lubricants, or dust/smoke created

when cutting, may contain chemicals

known to the State of California to cause

cancer, respiratory problems, birth defects,

or other reproductive harm. Minimize

exposure to these chemicals by wearing

approved personal protective equipment

and operating in a well ventilated area.

16. Difﬁcult Operations: Attempting

difficult operations with which you are

unfamiliar increases the risk of injury.

If you experience difficulties performing

the intended operation, STOP! Seek an

alternative method to accomplish the

same task, ask a qualified expert how the

operation should be performed, or contact

our Technical Support for assistance.

-8-

For Machines Mfg. Since 8/09

Model SB1020 SAFETY

Additional Metal Bandsaw Safety

1. Blade Condition. A dull or damaged

blade can break apart during operation,

increasing the risk of operator injury. Do

not operate with a dull, cracked or badly

worn blade. Inspect the blade for cracks or

missing teeth before each use.

2. Hand Placement. Hands could be cut

by the blade or crushed when lowering

the headstock. Never position ﬁngers or

thumbs in line with the cut or under the

headstock while it is moving.

3. Blade Guard. Hands and ﬁngers can easily

be cut by the bandsaw blade. To reduce the

risk of laceration injuries, do not operate

this bandsaw without the blade guard in

place.

4. Starting Position. To reduce the

likelihood of blade breakage and possible

entanglement, never turn the saw ON

with the blade resting on the workpiece.

5. Blade Replacement. The blade can only

make a safe and efﬁcient cut if the teeth

are facing the workpiece. When replacing

blades, make sure the teeth face toward

the workpiece. Wear gloves to protect

hands and safety glasses to protect eyes.

6. Workpiece Handling. A shifting workpiece

can result in impact or laceration injuries.

To reduce the risk of injury, always securely

clamp the workpiece in the vise and use

additional support ﬁxtures if needed. Never

hold the workpiece with your hands during

a cut. Flag long pieces to reduce the risk of

tripping over them.

7. Power Interruption. Unplug the machine

and turn the power switch OFF after a

power interruption. If left plugged in and

turned ON, this machine will start up when

power is restored, resulting in possible

entanglement, laceration, or amputation

hazards.

8. Hot Surfaces/Sharp Edges. Due to the

cutting process, a freshly cut workpiece,

chips, and some machine components can be

hot enough to burn you and sharp enough to

cut you. Allow components to cool and use

safe handling methods to reduce the risk of

these injuries.

9. Moving Blade. A moving bandsaw blade

presents a serious risk for laceration or

amputation injuries. Always allow the blade

to come to a complete stop before mounting

or repositioning a workpiece in the vise.

Never touch a moving blade.
