QualifyQualifyYYour Customer!our Customer!Start with 3 basic questions:

√ Which abrasive applications do you perform?(Such as grinding, polishing, sanding, finishing, deburring, graining, cleaning, etc.)

√ What kind of tools are you using?(Electric, pneumatic, hand, stationary,portable, etc.)

√ What concerns or problemsexist with your current method?(Takes too long, too messy, machine damage,operator discomfort, abrasive cost, etc.)

8

DYNABRADE®

Ask Relevant Questions1.) What type of compressor do you have?

How much horsepower does it generate?Screw, piston, big, small, old new, etc.?

2.) May I see your set-up?Look for:

• Plug type • Dust• Air hose size • Competition / Brand name• Air leaks

3.) Are your workers/operators satisfied withthe comfort level of your current tools?

• Too heavy? • Noisy?• Too cold? • Hard to handle?• Vibrate? • Frequent breakdown?

4.) May I quickly check a few things?• Use gauge to check available pressure• Check air line set-up (dead end or loop?)

Your customer will begin to see you as a “Professional!”

Demo,Demo, Demo,Demo, Demo!Demo!The only way to sell a Dynabrade tool

is to DEMONSTRATE it!

The best way to demonstrate the tool is to let the OPERATOR run it!

Ask the operator to note these features:• Lightweight

• Comfortable

• Quiet when running

• WARM - not cold!

For a successful demo, always:• Ensure that the abrasive is correct

• Ask the operator if he has any concerns

• Remind the operator that the Dynabrade toolis part of a complete SYSTEM

• Explain that we offer full technical support

• Take your time!!

√ Air must be clean. Use an air line filter-separator. Clean or replace filter element periodically.

√ Lubricate air motor properly.Use a filter-regulator-lubricator; follow manufacturer’s recommendations for proper usage of oil.

√ Check for air pressure drop.Bends in air hose can result in significant loss of air pressure.

√ Select the right air motor for the job.Motor should provide the needed horsepower or torque by using only two-thirds of available line pressure.

Tool PerformanceHorsepower - is a function of Torque x Speed / Constant

Air Flow - as the flow increases the pressure decreases

Efficiency - the more efficient the motor design, the greater the performance (in other words).

Reducing the amount of losses in air flow will increase the performance

Features of a tool design that affect performance:

15

DECREASEPERFORMANCE:

Increased clearances between mating parts

Too small or too longan air supply line

Small diameter motors that normally run at high speed,

that are choked down to lessthan 50% of their proper

output speed

INCREASEPERFORMANCE:

Precision machined tolerances

Proper air flow

Compressed Air Distribution System:Six General Rules

1. Pipe Sizes: Pipe sizes should be long enough that the pressure drop between the receiver and the point of use will not exceed 10 percent of the initial pressure. Fittingoffering the least amount of resistance to flow, such as long-radius elbows and maximum air flow connections, should be selected. Provisions should be made not only for present requirements but also for reasonable future growth.

2. Loop System: Where it is possible, a loop system around the plant within each shopand building is recommended. This gives a two-way distribution system to the pointwhere air demand is the greatest. The loop pipe should be large enough that the pressure drop will not be excessive at any outlet regardless of the direction of flow around the loop.

3. Distribution System: Long distribution lines, including those in a loop system, should have receivers of a liberal size located near the far end or at the points of heavy use. Many peak demands for air are of a short duration, and storage capacitynear such points avoids excessive pressure drop and may permit the use of a smaller compressor.

4. Point of Use: Each header or main should be provided with outlets as close as possible to the point of application. This permits the use of shorter hose lengths andavoids large pressure drops through the hose. Outlets should always be taken from the top of the pipeline to prevent carryover of condensed moisture to tools.

5. Piping: All piping should be sloped so that it drains toward a drop leg or moisture trap in order that condensation may be removed to prevent its reaching air-operated devices in which it would be harmful. The slope of the line should always be away from the compressor to prevent flow back into the compressor cylinder. A slope of about 1/4" per foot (2.0 mm/m) may be used, with drains provided at all low points. These may consist of a short pipe with a trap or drain at the bottom.

6. Distribution System: For a system using only oil-free compressors, it is strongly recommended that corrosion-resistant pipe be used. Unlike a system using lubricat-ed compressors in which an oil film will form to protect the pipe from the corrosive effect of the moisture in the air, a non-lubricated system will experience corrosion. This corrosion can lead to contamination of products and control systems.
