1.2 General Power Tool Safety Warnings

WARNING! Read all safety warnings, instructions, illustrations and specifications provided with this power tool.
Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your electrically-operated (corded) power tool or battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2) 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 and moving parts. Damaged or
entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors only, use an extension cords suitable for out- door 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.
3) Personal safety
a) 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 momentary lack of attention while operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c) 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.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f) 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.
g) 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.
h) 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.
4) Power tool use and care
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 at the rate for which it was designed. b) 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.
c) 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.
d) 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.
e) 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.
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, 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.
h) 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 unex- pected situations.
5) Battery tool use and care

a) 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.
b) WARNING! Use power tools only with specifically designated battery packs and respectively battery types. Use of any other battery packs may create a risk of explosions, injury and fire.
c) 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.
d) 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.
e) Do not use a damaged or modified battery. Damaged or modified batteries can behave unexpectedly and lead to fires, explosions or injuries.
f) Do not expose a battery for fire or high temperatures. Fire or temperatures above 130°C (265°F) can cause an explosion.
g) 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.

6) Service
a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool  is maintained.
b) Never service damaged batteries. All maintenance of batteries should only be carried out by the manufacturer or authorised customer service points.

4.2 Changing the battery  (B-1)

Slide the battery in until you hear it lock into place. Remove the battery by pressing down on the lock and then pulling the battery out.
Using a battery with at least 4.0Ah is recommended to ensure the optimum processing of pipes with large diameters. Otherwise, the device’s power might be insufficient and the device will switch off during the operating cycle.
4.3 Commissioning (B-2)
The unit provides a device for setting the bending angle automatically from 0º to 180º.
Loosen the graduated scale surrounding the former shaft and align the desired angle.
The machine is now set up and ready for use.
4.4 Operation (C)
For all bending applications, carefully follow the steps described!
Select the tube or pipe to be bent. Choose the relevant bending former and shoe suited to the tubes size.
Ensure that the ROBEND 4000 E is set in the start position by starting the motor with the direction lever in the reserve position until it triggers off and moves to the neutral position.
Place the bending former onto the centrepin. Lay the tube into the bending former and secure it into the hook.
Ensure that the tubes is fully inserted into the hook and has contact with the whole hook surface.
Secure the bending shoe with the fastening bolt into the appropriate housing.
Ensure you are at the correct starting position by checking the “0” mark on the bending former is lined up with the centre of the bending shoe.
To start bending, shift the direction lever to the working position and push the power switch. The bending former will start to rotate.
Maintain pressure on the switch until your chosen angle of bend (marked on the bending former) lines up with the mark on the bending shoe, and then release the switch. The ROBEND® 4000 is equipped with a device that allows you to preset the bending angle be- tween 0 to 180 degrees which is ideal for repeat bends. See “preparation for start up”.
Once the been has bend produced and the power switch has been released, shift the direction lever back into the reverse position. Briefly push the power switch to loosen the hold on the tube. Once the tube has released you can remove the fastening bolt, then the bending shoe and finally take the finished bend out of the bending former.
In order to make the ROBEND 4000 E ready for the next bending operation, start the motor with the direction lever in the reverse position until it triggers off and moves into the neutral position.
