To reduce the risk of injury, turn unit off and disconnect it from power source before installing and

removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

KEEP MACHINE CLEAN

Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth.

NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.

Wear certified safety equipment for eye, hearing and respiratory protection while using compressed air

FAILURE TO START

Should your machine fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet.

Also, check for blown fuses or open circuit breakers in the line.

LUBRICATION & RUST PROTECTION

Apply household floor paste wax to the machine table, extension table or other work surface weekly. Or use a

commercially available protective product designed for this purpose. Follow the manufacturer's instructions for use and

safety.

To clean cast iron tables of rust, you will need the following materials: a medium sized scouring pad, a can of spray

lubricant and a can of degreaser. Apply the spray lubricant and polish the table surface with the scouring pad. Degrease

the table, then apply the protective product as described above.

OVERLOAd PROTECTOR

Your scroll saw is equipped with a 3 amp overload

protection fuse. If your scroll saw becomes overloaded

and stops operating, turn off the scroll saw, check for a

blown fuse by removing the fuse cap (Figure 12). Your

scroll saw uses fuse #3AG Fast Acting, 1-1/4" (31.7 mm)

long x 1/4" (6.3 mm) diameter.

BRUSHES

Inspect carbon brushes regularly by unplugging tool,

removing the brush inspection cap (Figure 12) and

withdrawing the brush assembly. Keep brushes clean

and sliding freely in their guides. Always replace a used

brush in the same orientation in the holder as it was prior

to its removal. If the brush is worn down to 3/8" (10 mm),

it must be replaced. Use only identical DELTA brushes.

New brush assemblies are available at DELTA service

centers. The tool should be allowed to "run in" (run at no

load) for 10 minutes before use to seat new brushes.

TABLE

Keep the table clean and free from oil, grease and pitch.

Treat the table with paste wax to help maintain its smooth

finish.
