General power tool safety warnings

WARNING Read all safety warnings, instructions, illustrations and speciﬁ cations provided with this power tool. Failure to follow all instructions listed below may result in electric shock, ﬁ re and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of ﬂ ammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodiﬁed plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

Personal safety

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the inﬂuence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your ﬁnger on the switch or energising power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

Power tool use and care

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 at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Battery tool use and care

Recharge only with the charger speciﬁ ed by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of ﬁ re when used with another battery pack.
Use power tools only with speciﬁ cally designated battery packs. Use of any other battery packs may create a risk of injury and ﬁre.
When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a ﬁ re.
Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, ﬂ ush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
Do not use a battery pack or tool that is damaged or modiﬁ ed. Damaged or modiﬁ ed batteries may exhibit unpredictable behaviour resulting in ﬁ re, explosion or risk of injury.
Do not expose a battery pack or tool to ﬁ re or excessive temperature. Exposure to ﬁ re or temperature above 130 °C may cause explosion.
Follow all charging instructions and do not charge the battery pack or tool outside the temperature range speciﬁ ed in the instructions. Charging improperly or at temperatures outside the speciﬁ ed range may damage the battery and increase the risk of ﬁre.

Service

Have your power tool serviced by a qualiﬁ ed repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

The indicated weighted effective value of acceleration has been measured against standard test procedures and can be used by way of comparison with another device. The indicated weighted effective value of acceleration can also be used as a preliminary evaluation of the exposure.

CAUTION The indicated weighted effective value of acceleration can differ during operation from the indicated value, dependent on the manner in which the device is used. Dependent upon the actual conditions of use (periodic duty) it may be necessary to establish safety precautions for the protection of the operator.

Preparations for Use

CAUTION Observe and follow the national rules and regulations for manual handling of load weights.

Electrical connection

Caution : Mains voltage present! Before connecting the electric pipe bender, the rapid charger or the power supply, check whether the voltage given on the rating plate corresponds to the mains voltage. On building sites, in a wet environment, indoors and outdoors or under similar installation conditions, only operate the electric pipe bending machine on the mains with a fault current protected switch (FI breaker) which interrupts the power supply as soon as the leakage current to earth exceeds 30 mA for 200 ms.
Rechargeable batteries (Fig. 1c (17))

Total discharging by undervoltage
The Li-Ion batteries may not drop below a minimum voltage because otherwise the battery could be damaged by “total discharge”, see graduated charging state display. The cells of the ROLLER’S Li-Ion battery are delivered pre- charged to approx. 40 %. Therefore the Li-Ion batteries must be charged before use and recharged regularly. Failure to observe this regulation of the cell manufacturer can lead to damage to the Li-Ion battery by total discharging.

Total discharging due to storage
If a relatively low charged Li-Ion battery is stored, self discharging can lead to total discharge damage of the battery after longer storage. Li-Ion batteries must therefore be charged before storing and recharged every six months at the latest and charged again before use.

NOTICE Charge the battery before use. Recharge Li-Ion batteries regularly to avoid their total discharge. The rechargeable battery will be damaged by total discharge.
Only use a ROLLER’S rapid charger for charging. New Li-Ion batteries and Li- Ion batteries which have not been used for a long time only reach full capacity after several charges. Non-rechargeable batteries may not be charged.

Machine status check, ROLLER’S Arco 22 V
ROLLER’S Arco 22 V is equipped with an electronic machine status check (Fig. 1c (18)) by a 2-colour green/red LED. The LED lights green when the battery is fully or still sufﬁciently charged. The LED lights red when the battery must be charged. If this status occurs during bending, bending must be completed with a charged Li-Ion battery. The LED lights red and the ROLLER’S Arco 22 V switches off if overloaded. After a short dwell time, the LED lights green again and bending can be continued. The LED ﬂ ashes red if the motor temperature has been exceeded. After a cooling time, the LED lights green again and bending can be continued. The cooling time is reduced when the ROLLER’S Arco 22 V is operated in idle mode. The LED lights red if an impermissible battery has been inserted. If the ROLLER’S Arco 22 V is not being used, the LED goes out after approx. 2 hours but comes on again when the device is switched back on.

Graduated charging state display (Fig. 1c (19)) of the Li-Ion 21.6 V battery
The graduated charging state display shows the charging state of the battery with 4 LEDs. At least one LED lights fffor a few seconds after pressing the key with the battery symbol. The more LEDs that light green, the higher the charging state of the battery. If a LED ﬂ ashes red, the battery must be charged.

Rapid charger (Rapid charger (Rapid charger (Accessory Art. No. 571585)
The left control lamp lights up and remains green when the mains plug is plugged in. If a battery is inserted in the rapid charger, the green control lamp ﬂ ashes to indicate that the battery is charging. The green light stops ﬂ ashing and remains on to signal that the battery is fully charged. If the red control lamp ﬂ ashes, the battery is defective. If the red control lamp comes on and remains on, this indicates that the temperature of the rapid charger and / or the battery is outside the permissible range of 0°C to +40°C.

Selecting the bending tools

ROLLER’S Arco (Fig. 1a), ROLLER’S Arco 22 V (Fig. 1c)
Put a bending former (1) corresponding to the pipe size onto the square driver (2). The mounting is designed such that the bending former can only be fully ﬁtted in one direction. Keep the back former (3) and the insert bolt (4) corresponding to the pipe size at the ready.

ROLLER’S Arco 50 (Fig. 1b), Ø 35 – 50
Put a bending former (1) corresponding to the pipe size onto the square driver 35 – 50 (12). The mounting is designed such that the bending former can only be fully ﬁtted in one direction. Keep the back former (3), the support 35 – 50 (11) and the insert bolt (4) corresponding to the pipe size at the ready.

ROLLER’S Arco 50 (Fig. 1b), Ø 10 – 40
Insert square driver 35 – 50 (12) and square driver 10 – 40 (14) into the drive unit. Put a bending former (Fig. 1a (1)) corresponding to the pipe size onto the square driver 10 – 40 (14). The mounting is designed such that the bending former can only be fully ﬁ tted in one direction. Keep the back former (3), the support 10 – 40 (13) and the insert bolt (4) corresponding to the pipe size at the ready.

NOTICE In ROLLER’S Arco 50 the support 35 – 50 (11) or support 10 – 40 (13) respectively should be attached above the back formers and bending formers for all sizes. Up to and including sizes 24 R75 (¾” R75) the support should also be attached below (15). This is hung in on one side to the square collar of the square driver 10 – 40 (14) and on the other side with the locating pin (16) in the outermost bore hole of the support at the bottom (15) marked out in the housing (see 3.1.).
The drive unit gets damaged when bending without this support at the bottom!

Operation

Working procedure
Turn/slide setting ring/slide (7) to »L« (reverse). Press the safety inching switch (8) whilst gripping the motor handle (9). The bending former turns clockwise into its starting position against a ﬁxed stop. Release the safety inching switch if possible before reaching the ﬁxed stop so that this starts up in run out, i.e. the built-in slip clutch is not unnecessarily loaded. Turn/slide setting ring/slide (7) to »R« (forward). Place pipe into bending former so that the pipe end protrudes at least 10 mm beyond the driver (10). With the pipe sizes 22 – 50 mm, the pipe must be pressed into the radius of the bending former. Apply the corresponding back former (3) and push the insert bolt (4) into the appropriate hole on the device.

NOTICE In ROLLER’S Arco 50 the support 35 – 50 (11) or support 10 – 40 (13) respectively should be attached above the back formers and bending formers for all sizes. Up to and including sizes 24 R75 (¾” R75) the support should also be attached below (15). This is hung in on one side to the square collar of the square driver 10 – 40 (14) and on the other side with the locating pin (16) in the outermost bore hole of the support at the bottom (15) marked out in the housing.

When bending without this support at the bottom the drive unit gets damaged!

Ensure here that the insert bolt (4) for the sizes up to 22 mm goes into the left-hand locating hole (5) and from size 28 mm into the right-hand locating hole (6).
Operate the safety inching switch (8) to bend the pipe. Towards the end of the desired bend, only press the switch lightly. The end point can then be approached slowly and therefore precisely. A scale is provided on each bending former which together with the marking/outer edge of the back former allows precise bending up to 180°/ Arco 50 up to 90°. Be aware that various materials spring back differently. If a 180°/ Arco 50: 90° bend is produced and the end position is reached, the slip clutch comes into action again. Release the safety inching switch immediately. Turn/slide setting ring/slide (7) to »L« (reverse). Allow the bending former to run back a few degrees until the pipe is unclamped by lightly pressing the safety inching switch (8). Pull out the insert bolt (4) and remove the bent pipe. When bending on site, the bending former too can be taken off for easier removal of the bent pipe. Only allow the bending former to return to its starting position after removal of the pipe as otherwise the produced bend might be damaged. When bending stainless steel pipes of pressﬁtting systems, it must be ensured that the marking on the pipe made by the driver (10) does not lie in the sealing area of the pressing joint.

Bending to measure
If a bend is to be in a certain place on the pipe, a length correction must be made according to the pipe size. The correction dimension X speciﬁ ed in Fig. 2 must be considered for a 90° bend / 45° bend. The nominal dimension L must be shortened by the value X here. If, for example, a 90° bend with pipe size 22 with bending radius 77 the dimension L is to be = 400 mm, the mark must be made on the pipe at 319 mm. This mark must then be placed at the 0 mark on the bending former as shown in Fig. 2. Please bear in mind that the correction dimension X is a recommended value and that it may be necessary to adapt the correction dimension X to different pipe materials.

Unit support ROLLER’S Arco, ROLLER’S Arco 22 V
A height-adjustable machine holder 3B (Accessory Art. No. 586100) or height adjustable machine holder WB (Accessory Art. No. 586150) for fixing to a workbench is available as an accessory.

Bending lubricant
Safety data sheet, see www.albert-roller.de → Downloads → Safety data sheets ROLLER’S bending spray (Accessory Art. No. 140121) ensures a continuous film of lubricant for reduced force and even bending. High pressure-resistant, acid-free Without HFC and therefore not harmful to the ozone layer.

Power supply unit (accessory art. no. 571578)
The power supply units are intended for mains operation of the cordless tools in place of the battery. The power supply units are equipped with overvoltage and temperature protection. The operating state is indicated by a LED. A lit LED indicates that the device is ready for operation. If the LED goes out or flashes, this indicates an overcurrent or impermissible temperature. The drive unit cannot be used during this time. After a dwell time, the LED lights again and work can be continued.

Maintenance

Notwithstanding the maintenance described below, it is recommended to send in the electric pipe bender, rapid charger and battery to an authorised ROLLER contract customer service workshop for inspection and periodic testing of electrical devices at least once a year. In Germany, such periodic testing of electrical devices should be performed in accordance with DIN VDE 0701-0702 and also prescribed for mobile electrical equipment according to the accident prevention rules DGUV, regulation 3 “Electrical Systems and Equipment”. In addition, the respective national safety provisions, rules and regulations valid for the application site must be considered and observed.

WARNING Pull out the mains plug or remove the battery before maintenance work!
Clean the power tool regularly especially when it has not been in use for a long time. Keep the bending contours of the bending former (1) and back former (3) clean. Clean plastic parts (e.g. housing) only with machine cleaner (Art. No. 140119) or a mild soap and a damp cloth. Do not use household cleaners. These often contain chemicals which can damage the plastic parts. Never use petrol, turpentine, thinner or similar products for cleaning. Make sure that liquids never get onto or inside the power tool. Never immerse the power tool in liquid.

Inspection / maintenance
Remove the mains plug or remove the battery before maintenance and repair work! This work may only be performed by qualiﬁed personnel.
The gear runs in a life-long grease ﬁlling and therefore needs no lubrication. The ROLLER’S pipe bending machines with universal motor have carbon brushes. These are subject to wear and must therefore by checked and changed by qualiﬁ ed specialists or an authorised ROLLER customer service workshop from time to time. In the battery-operated drive units, the carbon brushes of the motor are subject to wear. These cannot be replaced; the DC motor must be replaced.

Faults

Disposal
The drive units, batteries and rapid chargers may not be thrown in the house- hold waste when they are ﬁnished with. They must be disposed of according to the legal regulations. Lithium batteries and battery packs of all battery systems may only be disposed of in the discharged state, all contacts of incompletely discharged lithium batteries and battery packs must be covered to with insulating tape.
