ECO-Torque 280 Controller

• The Gesswein ECO-Torque 280 Controller has a Voltage Selector

Switch that lets you use it with either 110V or 220V electricity.

• Control the handpiece speed using the Dial Rheostat or the On/O

Foot Switch.

• Direct/Remote Switch - Set to HAND when controlling handpiece

speed by Dial Rheostat. Set to FOOT when using the On/O Foot

Pedal.

QUICK TIPS

Before You Start

Check the Selector Switch to be sure it is set at the proper AC voltage.

Warm Up

Before rst use, run the handpiece at a slower speed without any load for 30

minutes. This will help ensure a smooth operation.

Important Note

Replacing Carbon Brushes

Replacement Carbon Brushes

SKU: 5105094

1. Be sure to replace both brushes at the

same time. Replacement of only one

carbon brush will cause motor damage.

2. To replace worn brushes, unscrew

the Carbon Brush Housing Cover in a

clockwise direction (Fig. 7).

3. Using a small Phillips Screwdriver,

unscrew each brush assembly.

4. The brush tension spring will push the

assembly out of the brush well so it can

be lifted clear.

5. The two new Carbon Brushes should be

installed by gently pushing them into the

brush well.

6. Screw the assembly in securely, and

replace the Carbon Brush Housing Cover

Expected brush life is 800–1,000 hours. Worn brushes should be replaced

when the handpiece no longer runs at maximum speed or sounds as though it

is “running out of gas.”

ECO-TORQUE 280 INSTRUCTION MANUAL

Safety Precautions

Read all safety precautions thoroughly to ensure proper and safe use.

Safety Precautions Suggestions

Set Voltage Selector

Switch

Before operating, be sure that the Voltage Selector

Switch is set to the voltage you will be running the unit

from.

Suggested

Temperature and

Environment

Suggested temperature range: 32–104°F (0–40°C).

Avoid use in dusty, warm, or humid environments to

prevent controller damage.

F/H Switch Make sure you have the F/H Switch on the proper

mode based on intended use.

Clear Controller

Ventilation

Ensure the Controller Ventilation Vents on the back of

the unit are not obstructed.

Prevent Stalling and

Damaging Motor

Ensure the Collet Release Ring is in the secure “S”

position before operating the handpiece. Operating

with the ring in the “R” release position may stall the

motor and cause damage.

Prevent Damage To

Motor

Avoid altering tools or rotating the Collet Release Ring

during handpiece operation, as it may cause the motor

to abruptly stop which can result in damage to both

parts and the motor itself.

Prevent Carbon

Brush and

Motor Armature

Commutator Wear

Avoid stalling the motor by pushing too hard on the

workpiece or exceeding the torque capacity of the

handpiece motor. This will cause excessive carbon

brush and motor armature commutator wear.

Do Not Exceed Max

RPM

Do not exceed the maximum rotation speed (RPM)

specied by the manufacturer/distributor of the

tool being used and adhere to the safe/ maximum

operating speeds.

Check Proper Shank

Size

Handpiece Collets are manufactured to close

tolerances. Use tools with a shank size that

corresponds to the Collet being used.

ECO-TORQUE 280 INSTRUCTION MANUAL

Safety Precautions (con’t)

Safety Precautions Suggestions

Prevent Shank From

Bending

Insert a tool fully into the Collet until it bottoms at the

back of the Collet. Using a tool not fully inserted is

dangerous and can cause the tool to vibrate or the tool

shank to bend.

Tool Precaution Never use tools out-of-round or with bent shanks.

Consistently Tighten

Collet

Periodically check to see that the Collet is fully

tightened. A loose Collet will cause the handpiece to

run slower.

Do Not Use Water

or Oil to Clean

Handpiece

Avoid using the handpiece in water or oil and keep

foreign matter out of the inner casing. This includes

dirt and excessive wood dust. Failure to do so may

result in damage to the ball-bearing assemblies.

Refer to Maintenance for cleaning instructions.

Forward/Reverse

Selector Switch to

OFF

Before operating the Forward/Reverse Selector

Switch, turn the controller OFF. Make the selection,

then turn the unit back ON

Do Not Drop

Handpiece

Take care not to drop the handpiece. Handpiece

bearings may be damaged and tool shanks bent.

Prevent Electric

Shock

To avoid electric shock, never plug or unplug the

Power Cord with wet hands.

Proper Safety

Glasses or Goggles

While operating the handpiece, wear protective safety

glasses or goggles at all times. Eyewear should meet

ANSI Z87.1 and GSA Z94.3 standards.

When Not in Use

Put the handpiece on the rubber cradle rest provided

or into the handpiece holder on the side of the unit.

Put a tool or Test Pin in the Collet when not using the

handpiece.

No Overload

Notication

Please note: there is no overload alert. Overloading

may cause the handpiece to continue until it

stops providing power. To restart, turn o the unit

briey before restarting. Monitor usage to prevent

overloading and damage to handpiece.
