Frequently Asked Questions - HPV 720 Cocraft

How do I start and stop the polisher?

Always hold the polisher with both hands. Set the speed regulator to MIN before pressing the trigger. To start, press the power trigger. For continuous operation, press the trigger lock button. To stop, press the front of the power trigger and release it. Always start and stop when the polishing sponge is resting on the surface.

How do I change the polishing sponge?

Unplug the polisher first. Remove the old sponge from the backing pad. Center the new sponge under the backing pad and press the pad onto it from above to ensure it is centered. The sponge should protrude equally all around the edge of the backing pad.

What speed should I use for polishing?

Always start at the lowest speed (MIN) and increase gradually during operation for best results. The speed regulator allows you to set speeds from MIN to 6 (max). Test on a scrap surface if unsure. Lower speeds are better for applying compound, higher speeds for final polish.

Can this polisher be used for sanding or grinding?

No, this tool is solely intended for polishing. Operations such as grinding, sanding, wire brushing, or cutting-off are not recommended and can lead to danger and personal injury. Use only accessories designed for polishing.

How do I balance the backing pad if the polisher vibrates excessively?

Excessive vibration can be due to an unbalanced pad. Unplug the tool. Push the backing pad inward to align the adjusting screw with the hole. Insert the included Allen key and turn clockwise if the new sponge is heavier, or anticlockwise if lighter. The counterweight compensates for weight differences up to 20 g.

What polishing compound should I use?

Only use liquid polishing compounds designed for machine use. Apply a small amount directly to the polishing sponge, not on the surface. Read the compound's instructions to ensure compatibility. Using too much compound makes polishing harder and reduces sponge life.

How should I maintain the polisher?

Disconnect from power before maintenance. Store with backing pad facing up to prevent deformation. Remove and wash the polishing sponge by hand, let air dry. Clean exterior with a damp cloth and mild detergent. Keep ventilation openings free of dust. Never use abrasive cleaners.

What safety precautions should I take?

Wear ear and eye protection. Read the entire manual before use. Keep children and bystanders away. Ensure the mains lead is away from rotating parts. Avoid loose clothing, jewelry, and long hair. Do not use near flammable materials. Always unplug when changing accessories or cleaning.

Why is my polisher vibrating more than usual?

Check that the polishing sponge is centered on the backing pad. If centered, try adjusting the speed. If vibration persists, balance the backing pad using the Allen key (see balancing instructions). Also inspect the sponge for damage; replace if worn or torn.

Can I use this polisher in wet conditions?

No, this polisher is intended for dry polishing only. Do not expose to rain or wet conditions. Using water or liquid coolants can result in electric shock. If outdoor use is unavoidable, plug into a socket protected by a residual current device (RCD).

Safety

General safety instructions for power tools

Warning: Read all the instructions.

Failure to adhere to the following instructions may lead to electric shocks, fires and/or serious injury.

SAVE THESE INSTRUCTIONS.

The term “power tool” in the following text refers to your handheld mains operated or battery operated tool.

1) Work area safety

a) Keep the work area clean and well illuminated. Cluttered and poorly lit areas invite accidents.
b) Do not use power tools in explosive environments, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite dust or fumes.
c) Keep children and other bystanders away from the area where you are using the power tool. Distractions can cause you to lose your concentration and control.

2) Electrical safety

a) The plug of the power tool must fit correctly into the wall socket. Never modify the plug in any way. Never use an adaptor plug together with earthed power tools. Unmodified plugs and matching outlets will reduce the risk of electric shocks.
b) Avoid physical contact with earthed objects such as pipes, radiators, ovens and refrigerators. There is an increased risk of electric shock if your body is earthed.
c) Do not expose the power tool to rain or other wet conditions. Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the mains lead. Never use the lead for carrying, pulling or unplugging the power tool. Keep the lead away from heat, oil, sharp edges and moving parts. Damaged or tangled leads increase the risk of electric shock.

e) When using power tools outdoors, use an extension lead that is suitable for this purpose. The use of an extension lead designed for outdoor use decreases the risk of electric shocks.
f) If the use of the power tool in a wet environment is unavoidable, a wall socket equipped with a portable residual current device (PRCD) should be used. Use of an RCD significantly reduces the risk of electric shock.

3) Personal safety

a) Pay attention to what you are doing and use common sense when using power tools. Never use power tools if you are tired or under the influence of drugs, alcohol or medication. One moment of inattention while using a power tool may result in a serious injury.
b) Wear protective clothing. Always wear safety glasses. Using protective clothing such as dust masks, non-slip safety shoes, helmets and ear defenders decreases the risk of injury.
c) Avoid accidental starts. Make sure that the power switch is set to OFF before plugging the power tool into a wall socket, fitting the battery or picking up/carrying the power tool. Never carry a power tool with your finger on the trigger and never connect the power tool to a wall socket when the switch is set to ON, since it may result in injury.
d) Remove all service tools/keys before switching on the power tool. A service tool left on a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f) Wear suitable clothing. Do not wear loose-fitting clothing or jewellery. Keep hair, clothes and gloves away from moving parts. Loose-fitting clothes, jewellery or long hair could become caught in moving parts.
g) If equipment for the extraction and collection of dust is available, make sure it is connected and used properly. Use of dust collection equipment can reduce dust related hazards.

4) Use and maintenance of the power tool

a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer if used at the rate for which it was designed.
b) Never use the power tool if the power switch does not switch the tool on and off properly. Any power tool that cannot be controlled by the power switch is dangerous and must be repaired.
c) Unplug the lead from the wall socket or remove the battery before making any adjustments, changing accessories or storing the power tool. These precautions reduce the risk of the power tool starting unexpectedly.
d) Store power tools that are not being used out of children's reach. Do not allow people who are unfamiliar with the tool or these instructions to operate the tool. Power tools are dangerous in the hands of untrained users.

e) Properly maintain your power tools. Check for misalignment, binding of moving parts, broken parts or anything else which might affect the operation of the power tool. If any damage is noticed, have the power tool repaired before using. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, and any accessories in accordance with these instructions, take into consideration the working conditions and the work that is to be performed. Use of the power tool for a purpose other than that for which it is intended could result in a dangerous situation.

5) Service

a) Repairs and service should only be performed by qualified tradesmen, and only with original spare parts. This guarantees that the safety of the power tool is maintained.

Specific safety precautions for polishing

• Polishing bonnets with drawstrings are not recommended, but if you are using one: Do not allow the polishing bonnet or its drawstring to hang loose when operating the polisher. Tuck in or trim off any loose ends. Loose and spinning attachment strings can entangle your fingers or snag on the workpiece.
• This angle polisher is only intended for dry polishing.
• Only use the recommended parts and/or accessories.
• The angle polisher must not be used by persons under the age of 16 years.
• The angle polisher must not be used on materials containing asbestos.

a) This power tool is solely intended for the purpose of polishing. Read all safety warnings, instructions, illustrations, and specifications provided with this tool. Failure to adhere to all of the following instructions can result in electric shock, fire and/or serious injury.

b) Operations such as grinding, sanding, wire brushing or cutting-off are not recommended to be performed with this power tool. The use of this power tool to perform tasks for which the tool was not intended, can lead to danger and personal injury.

c) Never use accessories which are not designed for use with this type of tool and which are not recommended by the manufacturer. Even if the accessory can be attached to your power tool, there is no guarantee that it can be used safely.

d) The rated speed of the accessory must at least correspond to the maximum rated speed of the power tool. Accessories which rotate faster than their rated speed can break and shatter.

e) The outer diameter and thickness of the accessory must be within the marked capacity of your electric hand tool. If an accessory is the wrong size, it will not fit the guard and will not be able to be controlled properly.

f) Do not use a defective accessory. Inspect the accessory and make sure there are no splits or cracks in the grinding wheels; cracks or wear and tear on the backing plates, loose or torn bristles on the steel brush wheels. If you drop your power tool or accessory, check for damage. If the accessory is damaged, use a new/undamaged accessory. After inspecting the tool and attaching an accessory, keep yourself and others outside of the power tool's danger zone and let it run at full speed for one minute. Damaged accessories will normally break during this test period.

g) Wear personal protective equipment. Depending on how you use the machine; use a visor/face protection or safety glasses. If necessary use a mask, ear protection, gloves, and apron/work clothing to protect you from small shards of metal or splinters from the work object. The eye protection you use must be able to protect against flying debris produced in different working positions. The breathing protection should be able to filter any particles produced by the work. Prolonged exposure to high levels of noise can result in hearing damage.

h) Keep children at a safe distance from the work area. Everyone at the workplace must wear personal protective equipment. Debris from the workpiece or from a damaged accessory can fly off and injure people outside of the immediate work area.

i) Position the mains lead well away from the rotating accessory. If you lose control, the lead can be sliced through or become entangled and pull your hand or arm into the rotating accessory.
j) Never put the power tool down before the accessory has completely stopped rotating. A rotating accessory can fasten on the work surface causing you to lose control of the tool.
k) Never leave the power tool switched on while carrying it at your side.
Accidental contact with the rotating accessory could snag your clothing, pulling the accessory into your body.
I) Clean the ventilation ports of the motor regularly. The fan of the motor draws dust into the housing. A large build-up of metal dust particles can lead to electrical hazards.
m) Do not use the power tool near flammable material. Sparks can easily ignite flammable material.
n) Do not use accessories, which require liquid coolants. The use of water or other liquid coolants can result in electrocution or shock.

Kickback and related warnings

• Kickback is a sudden reaction to a wedged or stuck wheel, backing plate, brush, or some other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn results in the power tool thrusting violently in the opposite direction of the accessory's rotation at the point of binding.
• Kickbacks are the result of the power tool being used in an incorrect manner, on incorrect objects, or under incorrect conditions and can be avoided by observing the following precautions.
  a) Hold the power tool firmly and position your arms and body so that you can resist kickback forces. Always use the auxiliary handle if there is one, for maximum control over kickback or torque reaction during start-up.
  The operator can control torque reactions or kickback forces, if proper precautions are taken.
  b) Never place your hand near the rotating accessory. The accessory can be thrown back onto your hand.
  c) Do not stand in the area, where the power tool is likely to end up if a kickback were to occur. Kickback will propel the tool in the opposite direction to the wheel's rotation at the point of snagging.

Outdoor use

• If the polisher is used outdoors, it is recommended that it is plugged into a socket protected by a residual current device (RCD). The RCD should be rated to trip at a current of 30 mA.
• Only use cables and connectors designed for outdoor use.

Operating instructions

Starting /Stopping

• Always hold the polisher in both hands and start and stop the polisher only when the polishing sponge is resting on the surface to be polished.
• Always start polishing on the lowest speed by setting the regulator (4) to MIN before pressing the trigger (6). Press in the trigger lock button (5) if you want the polisher to keep running all the time.
• Switch the polisher off by pressing in the front of the power trigger (6) and then releasing it.

Variable speed control

Set the desired speed, from MIN to 6 (max), using the regulator (4). Always begin on the lowest speed (MIN) and increase during operation for the best results. If you are unsure, it is a good idea to test the polisher at different speeds on a test surface before starting work.

Changing polishing sponge/ buffing pad

The various accessories which can be used with the polisher are all referred to as polishing sponge below.

1. Unplug the polisher and remove the polishing sponge (11) from the backing pad (10).
2. The polishing sponge should be centred on the backing pad. This is easiest to achieve by holding the polishing sponge underneath and pressing the backing pad onto it from above. If the polishing sponge is fitted in this way, it is easy to make sure that it is centred, i.e., that it protrudes equally all the way round the edge of the backing pad.

Vibration level

The polisher normally vibrates during use due to its oscillating action. If the polisher vibrates a great deal, check that the polishing sponge is centred on the backing pad. You could also try adjusting the speed until the polisher vibrates less. There is also a way of balancing the backing pad in relation to the weight of the polishing sponge (see the next section).

Balancing the backing pad in case of abnormal vibrations

• The backing pad is factory-balanced for a polishing sponge of the recommended dimensions.
• This factory-balancing is suitable for most polishing sponges with equivalent dimensions and normally no adjustment is necessary.
• However, if abnormally heavy vibrations are experienced when using a polishing sponge of another size, the backing pad can be balanced by moving a counterweight on the spindle.
• The counterbalance can only be used to compensate for weight differences up to 20 g from the recommended polishing sponge weight.

The counterweight is adjusted using the included Allen key.

1. Push the backing pad inwards (towards the power trigger) so that the adjusting screw (12) is lined up with the hole (9).

2. Insert the included Allen key (8) through the hole (9) and into the adjusting screw (12). Turning the adjusting screw, moves a small counterweight (13) in/out to compensate for the change in weight of the polishing sponge used.

- Turn the Allen key clockwise if the new polishing sponge is heavier than the preceding sponge.

- Turn the Allen key anticlockwise if the new polishing sponge is lighter than the preceding sponge.

The picture shows how to balance the backing pad.

Polishing

The various polishing products such as rubbing compound, finish cleaner, wax, polish are all referred to below as polishing compound.

• There are several types of polishing compound which can be used, but this angle polisher is designed for use with liquid polishing compound.

• Always read the instructions accompanying the polishing compound to ensure that it is suitable for use with a polishing machine.

• Unplug the polisher and fit a polishing sponge onto the backing pad. Only use clean and undamaged polishing sponges and change them if you change the type of polishing compound. Most polishing sponges are washable, so all you need to do is have a few of them so you can wash them and reuse them.

• Apply the polishing compound to the polishing sponge. Begin by applying a small amount of polishing compound. Do NOT spread polishing compound onto the surface to be polished.

1. Place the mains lead of the polisher over your shoulder to keep it out of the way whilst polishing. Note: Hold the polisher in both hands so that the polishing sponge rests on the surface to be polished and begin polishing on the lowest speed setting. Move the polisher up and down over the surface to be polished applying a light pressure. Keep the polisher moving all the time as paint finishes can be ruined if polishers are left polishing one spot for too long.

2. Intricate surfaces such as wing mirrors, door handles and grilles should be polished by hand.

- The most common mistake made when polishing is the use of too much polishing compound. Soaking the polishing sponge with polishing compound will make polishing more difficult and increase the polishing time. Using too much polish will shorten the useful life of the polishing sponge/pad.

- If the polishing sponge detaches itself from the backing pad, you have probably used too much polishing compound.

Maintenance

• Disconnect the plug from the power source before making any adjustments or servicing.
  • Always store the polisher with the backing pad facing up to prevent it from deforming.
• Remove the polishing sponge from the backing pad when you have finished work.
• Wash the polishing sponge by hand and let it air dry.
• Never use abrasive cleaning agents.

• Clean the exterior of the polisher using a cloth lightly moistened with water and a mild detergent.

• Do not use the polisher in the rain or if you have wet hands.

• Ensure that the ventilation openings are kept clear to prevent the motor from overheating.
• When working in dusty conditions: First disconnect the polisher from the mains supply and then clear the ventilation openings of any dust.
