WARNING Before gaining access to the terminals all power sources should be disconnected.

Power requirements

WARNING: Tools with double insulation and reinforced insulation are equipped with a polarized plug (one prong is wider than the other) This plug will only fit in the right way into a polarized outlet. If the plug cannot be introduced into the outlet, reverse the plug. If it still doesn’t fit, call a qualified electrician to install for you a polarized outlet. Do not alter the plug in any way. Both insulation types eliminate the need for a grounded third power cord with three prongs or a grounded power connection.

WARNING: When using an extension cable, verify the gauge is enough for the power that your product needs. A lower gauge cable will cause a voltage drop in the line, resulting in power loss and overheating. The following table shows the right size to use depending on the cable’s length and the ampere capability shown in the tool’s nameplate. When in doubt use the next higher gauge.

WARNING: When operating power tools outdoors, use a VOLTECK grounded extension cable labeled “For Outdoors Use”. These extensions are specially designed for operating outdoors and reduce the risk of electric shock.

WARNING! Read carefully all safety warnings and instructions listed below. Failure to comply with any of these warnings may result in electric shock, fire, and/or severe damage. Save all warnings and instructions for future reference. The term ‘power tool’ in the warnings refers to both your main (corded) power tool and the cordless power tool.

Kickback and related warnings

• Kickback is a sudden reaction when a rotating wheel, backing pad, brush, or any other accessory becomes jammed or snagged. Jamming or snagging causes a rapid stoppage of the rotating accessory, which in turn forces the power tool uncontrollably in the opposite direction of the accessory’s rotation at the point of operation.
• Kickback can occur because of misuse of power tools and/or incorrect operating procedures or inappropriate conditions and can be avoided by taking the essential precautions outlined below:
• Maintain a firm grip on the power tool, keep your body and arm positioned to resist kickback forces.
• Always use the auxiliary handle if provided, for maximum control over kickback or the motor’s torsional reaction during startup.
• The operator can control torsional moment and kickback forces with proper precautions.
• Never place your hand near the rotating accessory.
• Accessories can kick back into the hand.
• Do not position your body in the area where the power tool may move if kickback occurs.
• This propels the power tool in the opposite direction of the disc’s movement at the point of engagement or snag.
• Exercise special care when working in corners, sharp edges, among others. Avoid bouncing and accessory snagging.
• When working in corners, sharp edges, or encountering bouncing, it can cause the accessory to snag and lead to loss of control of the power tool or kickback.

Damaged accessories typically break during this period.

Operating instructions

• D-handle: For your safety, use the D-handle.
• Polishing disc installation: Mount the rubber disc and wool disc on the shaft, press the shaft lock, and screw the disc tightly.
• Variable speed and soft start: Adjust the continuously variable speed regulator from 1 000 rpm to 3 500 rpm as needed, with the highest speed at the ‘6’ position, gradually decreasing at the ‘1’ position. Always turn off and wait until the polishing wheels have completely stopped before storing the machine.

Polishing pads

• Polishing sponges or any other polishing accessory are directly mounted to the disc with hook and loop fastening.
• To install the sponge, first remove any dirt or foreign materials that may adhere to the surfaces of the disc and interchangeable accessories. Place the sponge on the hook and loop fastening disc so that the edges are aligned.
• The polisher includes the following interchangeable accessories:
  1. Sanding discs
  2. Polishing sponges
  3. Buffing wheel
• To remove the sponge, simply pull it by the edge.

CAUTION: Ensure that the pad and the sponge are aligned and properly installed. Otherwise, the sponge may cause excessive vibration, leading to loss of control, or the sponge may be expelled from the tool.

Polishing application: Most polishes come in paste or liquid form. Before using any polish, read all instructions regarding the product’s uses and the correct application method.

Application of liquid polish.

• Apply a small circle of liquid, approximately 3 cm in diameter, in the center of the buffing wheel, followed by two more rings, each slightly larger than the previous one.
• After the initial application, the buffing wheel doesn’t absorb as much liquid. Therefore, apply only two rings, using half of the initial amount.
• Application of paste polish.
  • Using a putty knife or any other flat, dull object, apply about a teaspoon of paste to the buffing wheel. Spread the paste evenly over the entire surface of the buffing wheel.
  • NOTE: Do not apply the paste directly to the surface being polished.
  • WARNING: The switch can be locked in the on position for the operator’s convenience during extended use. Be careful when locking the tool in the on position and keep a firm grip on the tool.

Startup

Power on and operation control

• Intermittent Operation:
  • Plug the tool into the outlet.
  • Press the switch (A) to make the tool start working.
  • To stop its use, simply release the switch.
• Continuous Operation:
  • Plug the tool into the outlet.
  • Press the switch (A) and lock it by pressing the continuous use button (B).
  • To interrupt its operation, press and then release the switch.
• Speed control
  • The tool can be operated at different speeds. These are selected by adjusting the speed control from minimum to maximum (C). Turn the speed control while referencing the speed chart (D).
  • Generally, low speeds are recommended for small work areas, and high speeds for larger surfaces. Use the speed that best suits the working conditions.
  • CAUTION: Continuous use of the tool at low speeds for an extended period will overload the motor and result in inefficient tool operation. The speed control dial can only be turned up to Max and back to Min. Do not force it beyond Max or Min, or the speed adjustment function may stop working.
• How to properly grip the tool
  • Always hold the tool with both hands. One hand gripping the main handle and the other the auxiliary handle (A) or D-handle (B). Be careful not to obstruct the ventilation slots.
• Polishing
  • Move the polisher back and forth over the working surface with long strokes.
  • Be aware that excessive pressure, incorrect angles, or improper movements can cause swirl marks or burns in the finish. To avoid them, do not use high speeds when polishing small areas, press the buffing wheel lightly onto the surface, and keep the polisher constantly moving without letting it stay static in one spot, especially near edges or changes in the working surface.
  • Follow the instructions of the polishing products for a quality job.
  • For best results, it is recommended to use original accessories such as the TRUPER brand BOR-PULA-7N.
  • The most common mistake is applying too much wax.
  • If the buffing wheel absorbs too much wax, it won’t last long, and the polishing job will be more difficult and take a long time to finish.
  • Always disconnect the tool before proceeding to clean it.
  • Never use water or other liquids; only use a brush.
  • To prevent the motor from overheating, regularly clean the ventilation slots.
  • The housing should not be cracked or damaged.
  • Always check that the cable is not cut or peeled.
  • After prolonged use, the grease in the tool head should be replaced at a TRUPER authorized Service Center.
  • CAUTION: Be attentive when polishing rough surfaces, joints, or crevices where the buffing wheel may get stuck. A stuck buffing wheel can make you lose control of the tool and/or burn the finish. To reduce this risk, use low speeds on rough surfaces, and for complicated surfaces such as mirrors or moldings, avoid using the tool and polish manually.
