SECTION 6: MAINTENANCE

Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious person- al injury.

Schedule

For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section.

Daily:

Check/correct loose mounting bolts.

Check/correct damaged or dull saw blade.

Check/correct worn or damaged wires.

Clean/protect table.

Clean metal chips from upper and lower wheel areas, and empty bottom chip pan.

Correct any other unsafe condition.

Monthly:

Check for V-belt tension, damage, or wear.

Lubricate tension leadscrews and guide post rack.

Remove the blade and clean the wheels.

Cleaning

Use a brush and a shop vacuum to remove chips and other debris from the machine. Keep the table rust-free with regular applications of products like G96® Gun Treatment, SLIPIT®, or Boeshield® T- 9 (see Section 5: Accessories on Page 36 for more details).

Once a month, remove the blade and thoroughly clean all metal chips or built-up grease from the wheel surfaces. Redress the rubber tires if neces- sary.

When cleaning the wheel areas, empty and clean the chip pan (see Figure 43).

Redressing Rubber

Tires

As the bandsaw ages, the rubber tires on the wheel may need to be redressed if they become hardened or glazed over. Redressing the rubber tires improves blade tracking and reduces vibra- tion/blade lead.

If the rubber tires become too worn, then blade tracking will become extremely difficult. At that point, redressing will no longer be effective, and the rubber tires must be replaced.

To redress the rubber tires:

1.DISCONNECT BANDSAW FROM POWER!

2.Put on heavy gloves and remove the blade.

3.Use a brush and shop vacuum to clean any chips from the rubber tires.

4.Hold a piece of 100-grit sandpaper against the rubber tire and rotate the wheel by hand. Only redress the rubber enough to expose a fresh rubber surface.
