Factors affecting performance checklist.

Abrasive

Follow basic sanding technique

■■

Frequently inspect discs for

■■

tears, folds or loading

Make sure work surface is

■■

debris-free before moving on to finer grade disc

Backup Pad

Match backup pad to the job

■■

(i.e., low profile for stock removal)

Confirm that tool and disc pad are

■■

the same diameter

Inspect for damaged pad —

■■

adhesion loss, worn foam

If increased conformability is needed

■■

attach a 3M foam interface pad

Tool

Check tool lubrication schedule

■■

(1–3 drops of tool lubricant daily is recommended)

Ensure that the speed control

■ ■

adjusted to 3/MAX

Test that the lever is undamaged

■■

and muffler is not clogged

Air Pressure

Check your gauge to make sure

■■

tools is running at 90 PSI

Use minimum length of air hose

■■

necessary — no more than 25 ft.

Ensure inside air line diameter is

■■

at a minimum 3/8"

Check airline fittings: 9/32" is best,

■■

3/16" is marginal

Why choose 3/32" orbit?

• To use with finer grades

• Least amount of stock removal

Why choose 5/16" orbit?

• More stock removal needed

than 3/16" orbit

• Not as aggressive as 3/8" orbit

Why choose 3/8" orbit?

• Most aggressive stock removal

• Good for large area sanding or

if high cut rate is needed

Why choose 3/16" orbit?

• Most commonly used orbit pattern

• Good balance of stock removal

and finish

Coarser finish/Increased cut

Start the sander ON the surface and stop OFF the surface.

This will help to avoid swirl marks.

Apply light hand pressure on the tool and allow the backup

pad to orbit freely. Let the tool do the work.

Run the tool flat on the work piece to prevent gouging.

Follow a set pattern when sanding. This ensures that previous

scratches are removed and a uniform finish is reached.

Optimize your sanding system with 3M™ Cubitron™ II and 3M™ Clean Sanding Systems

Create a Safer and Cleaner Workspace

Sanding debris is removed directly from the workpiece as an operator sands with the system.

With a convenient and ecient dust free system, the work environment is cleaner and more

comfortable for all workers.

System

• Clean Sand

Clean sanding discs remove more

dust and last longer than 5- and

6-hole discs of a similar diameter.

Improve Sanding Disc Performance

A disc loads less when the dust it generates is vacuumed away. Less loading means more of the disc’s abrasive surface is in direct contact with the workpiece. More direct disc contact provides better cut rate and less disc loading equals longer life.

Save $$$ on Abrasives and Improve Productivity

With longer life and a faster cut rate, less discs are used to complete a job. Not only can disc

consumption be reduced, each job can be done faster, improving a shop’s overall productivity.
