Additional Safety Instructions for Metal

Cutting Bandsaws

1. BLADE CONDITION. Do not operate with

dull, cracked or badly worn blade. Inspect
blades for cracks and missing teeth before
each use.

2. HAND PLACEMENT. Never position fin­gers or thumbs in line with the cut. Hands
could be crushed in vise or by falling
machine components.

3. ENTANGLEMENT HAZARDS. Do not
operate this bandsaw without blade guard
in place. Otherwise, loose clothing, jewelry,
long hair and work gloves can be drawn
into working parts.

4. BLADE REPLACEMENT. When replacing
blades, make sure teeth face toward the
workpiece. Wear gloves to protect hands
and safety glasses to protect eyes.

5. WORKPIECE HANDLING. Always support
the workpiece with table, vise, or some
type of support fixture. Flag long pieces
to avoid a tripping hazard. Never hold the
workpiece with your hands during a cut.

6. LOSS OF STABILITY. Unsupported
workpieces may jeopardize machine sta­bility and cause the machine to tip and fall
which could cause serious injury.

7. POWER INTERRUPTION. Unplug machine
after power interruption. Machines without
magnetic switches can start up after power
is restored.

8. FIRE HAZARD. Use EXTREME CAUTION
if cutting magnesium. Using the wrong cut­ting fluid will lead to chip fire and possible
explosion.

9. CUTTING FLUID SAFETY. Always follow
manufacturer’s cutting fluid safety instruc­tions. Pay particular attention to contact,
contamination, inhalation, storage and dis­posal warnings. Spilled cutting fluid is a
slipping hazard.

10. ATTENTION TO WORK AREA. Never
leave a machine running and unattended.
Pay attention to the actions of others in the
area to avoid unintended accidents.

11. MAINTENANCE/SERVICE. All inspec­tions, adjustments, and maintenance are
to be done with the machine OFF and the
plug pulled from the outlet. Wait for all
moving parts to come to a complete stop.

12. HEARING PROTECTION & HAZARDS.

Noise generated by blade and workpiece
vibration, material handling, and power
transmission can cause permanent hear­ing loss over time and interfere with com­munication and audible signals. Always
wear hearing protection.

13. HOT SURFACES. Due to friction, the
workpiece, chips, and some machine com­ponents can be hot enough to burn you.

No list of safety guidelines can be complete. Every shop environment is different. Like all
machines there is danger associated with the Model G9742. Accidents are frequently caused by
lack of familiarity or failure to pay attention. Use this machine with respect and caution to lessen
the possibility of operator injury. If normal safety precautions are overlooked or ignored, serious
personal injury may occur.

Clean Up

Site Considerations

The unpainted surfaces are coated with a waxy
oil to prevent corrosion during shipment. Remove
this protective coating with a solvent cleaner or
degreaser, such as shown in Figure 4. For thor­ough cleaning, some parts must be removed.

For optimum performance, clean all moving
parts or sliding contact surfaces. Avoid chlo-

rine-based solvents, such as acetone or brake
parts cleaner that may damage painted surfac­es. Always follow the manufacturer’s instructions
when using any type of cleaning product.

Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. DO
NOT use these products
to clean the machinery.

Floor Load

Refer to the Machine Data Sheet for the weight
and footprint specifications of your machine.
Some floors may require additional reinforcement
to support both the machine and operator.

Working Clearances

Consider existing and anticipated needs, size of
material to be processed through each machine,
and space for auxiliary stands, work tables or
other machinery when establishing a location for
your new machine. See Figure 5 for the minimum
working clearances.

Many cleaning solvents
are toxic if inhaled.
Minimize your risk by only
using these products in a
well ventilated area.

G2544—Solvent Cleaner & Degreaser

A great product for removing the waxy shipping
grease from your machine during clean up.

Figure 5. Minimum working clearances.

Unsupervised children and
visitors inside your shop
could cause serious per­sonal injury to themselves.
Lock all entrances to the
shop when you are away and
DO NOT allow unsupervised
children or visitors in your
shop at any time!
