General Safety Instructions

Read all the safety notes, instructions, illustrations and technical data which
come with this power tool. Failure to heed the following instructions can lead to electric shock, fire and/or severe injuries.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains­operated (corded) power tool or battery­operated (cordless) power tool.

Work area safety

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

Electrical safety

1. 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.
2. 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.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
4. Do not misuse the connecting cable to carry or hang up the power tool or to pull the plug out of the socket. Keep the connecting cable away from heat, oil, sharp edges or moving tool parts. Damaged or knotted cables increase the risk of electric shock.
5. 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.
6. 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

1. 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.
2. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non­skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
3. 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.
4. 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.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
7. 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 dust­related hazards.
8. Do not take your safety for granted and ignore the safety rules for power tools even if you are very familiar with the power tool after frequent use. Careless handling can lead to severe injury within split seconds.

Power tool use and care

1. 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.
2. 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.
3. Disconnect the plug from the power source and/or the battery pack 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.
4. 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.
5. Maintain power tools. 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.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. 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.
8. Keep handles and gripping surfaces dry, clean and free from oil and grease. Slippery handles and gripping surfaces prevent safe handling and control of the power tool in unforeseeable situations.

Battery tool use and care

1. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
2. Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
3. 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 fire.
4. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
5. Do not use a damaged or modified battery. Damaged or modified batteries can behave unexpectedly and lead to fires, explosions or injuries.
6. Do not expose a battery for fire or high temperatures. Fire or temperatures above 130 °C (265 °F) can cause an explosion.
7. Follow all the instructions for charging and never charge the battery or the cordless tool outside the temperature range specified in the operating instructions. Incorrect charging or charging outside the permitted temperature range can destroy the battery and increase the fire risk.

Service

1. Have your power tool repaired only by qualified technical personnel and only with genuine spare parts. This ensures that the safety of the device is maintained.
2. Never service damaged batteries. All maintenance of batteries should only be carried out by the manufacturer or authorised customer service points.

Preparations for Use

Electrical connection

Caution: Mains voltage present! Before connecting the electric pipe bending machine or the rapid charger, 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

Always hold the battery (17) upright when inserting it in the drive unit or the rapid charger. If inserted at an angle it can cause damage to the contacts and result in a short circuit which damages the battery.

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”. The cells of the REMS 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 mregulation 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.

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 REMS 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.

Rapid charger Li-Ion/Ni-Cd (Art. No. 571560)
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 flashes to indicate that the battery is charging. The green light stops flashing and remains on to signal that the battery is fully charged. If the red control lamp flashes, 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 +45°C.

The rapid chargers are not suitable for outdooruse.

Selecting the bending tools

REMS Curvo (Fig. 1a), REMS Akku-Curvo (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.

REMS Curvo 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.

REMS Curvo 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 fitted 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.

In REMS Curvo 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

Use ear protection

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.

In REMS Curvo 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 on the back former allows precise bending up. to 180°/ Curvo 50 up to 90°. Be aware that various materials spring back differently. If a 180°/ Curvo 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 safetyinching 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 specified in Fig. 2 must be considered for a 90° bend. The nominal dimension L must be shortened by the value X here. if, for example, 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.

Unit support REMS Curvo, REMS Akku-Curvo

A height-adjustable machine holder 3B (Art. No. 586100) or height-adjustable machine holder WB (Art. No. 586150) for fixing to a workbench is available as an accessory.

Bending lubricant

REMS bending spray (Art. No. 140120) 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.

Low Discharge Protection

REMS Akku-Curvo is equipped with low discharge protection for the battery.
This switches off the power tool as soon as the battery needs to be recharged. In this case remove the battery and charge with the REMS rapid charger.

Maintenance

Maintenance

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 REMS CleanM 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

Pull out 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.
