Frequently Asked Questions - ROBULL ROTHENBERGER

How to use the ROBULL bender?

Place the guide flanges on the cylinder, secure them with the pins. Position the diabolo rollers according to the tube diameter. Fit the bending die onto the piston, place the tube and close with the upper flange. Before use, make sure there is no air in the circuit by opening the release valve and pumping several times. Close the valve, open the reservoir cap, then pump or start. 90° bending is done in one operation.

What hydraulic oil to use?

Use a good quality hydraulic oil of type ISO 32. Never use brake fluid. The recommended oil volume is 850 cc, but the fill should reach about 70% of the reservoir capacity (1,250 cc).

How to check the oil level?

Lift the front part of the cylinder about 45°. The oil level should reach the filler hole. If necessary, add filtered ISO 32 oil avoiding debris.

What to do if the piston does not advance?

First check the oil level. Make sure the release valve is properly closed. If there is air in the circuit, open the valve and pump several times to purge. If the problem persists, clean the suction valve.

How to purge air from the hydraulic circuit?

Place the cylinder in a nearly vertical position (piston up), open the release valve, and pump until suction is perfect. Then reposition the cylinder horizontally for work.

What types of tubes can be bent?

The ROBULL bender can cold bend black or galvanized iron tubes complying with standard EN 10255 (medium and heavy series), without deformation.

How to clean the valves?

If debris blocks the valves, retract the piston, disassemble the relevant valve (suction, discharge, or retention) and clean it thoroughly. Then reassemble and purge the circuit.

Where to find spare parts?

Order your accessories and spare parts from your specialized dealer or directly from ROTHENBERGER customer service (+49 (0) 61 95/ 800 8200).

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 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.

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 dust-related 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 unexpected situations.
5) 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.

3 Function of the Unit

With the ROTHENBERGER pipe bender you can cold bend galvanized or black steel pipes of the following types, without filling, and without reamers on the inside:

Steel Pipe EN 10255 Medium and heavy series

The angles we can effect with these benders range from 0^ to 180^ . A right angle can be made directly, while others can be effected with several curves.

These angles can be in different planes. The equipment could be hand operated or electrically, with automatic, piston return.

3.1 Starting up and using the two-plate pipe bender

→ Fit the guide plates to the front flange and secure them with pins.
→ Fit the diabolos to the lower plate, in the position corresponding to the size of the pipe to be bent. At the same time fit the diabolo in position in accordance with the size of the pipe.
→ At the end of the piston, fit the former corresponding to the size of the pipe that it is desired to bend. Place the pipe in position and put down the upper plate.
→ In the event that the pipe to be bent is welded, the weld beam should be placed either in the upper or lower side position.
→ Before starting to use the pipe bender, release any pressure there may be in the valve system of the hydraulic circuit. Do this by opening the return cock and pumping several times with the lever or switch on the motor.
→ Make sure the return valve is well closed, and the tank plug open.
→ You can then begin to operate the pump lever or switch on the motor.
→ When the bend has been finished, return the piston by loosening the return valve on the side of the
→ distributor.

4 Care and Maintenance

Check oil level at regular intervals.

When topping up, be especially sure to filter the oil so that it is free of extraneous matter. Check its level by lifting the front part of the unit about 45^ and looking in. The oil should reach the level of the hole used for loading it in.

When the oil has been topped up, fit the unit in inclined position, i.e. almost vertical, and with the piston upward. Open the return valve and work the pump with the lever until suction is as it should be. After a short space of time with the position unchanged, and when suction is satisfactory, fit in horizontal working position.

In the event that it is necessary to top up, use a high-quality hydraulic oil. Never use brake fluid. Bear in mind that excess of oil will render the equipment inoperative. Accordingly fill to about 70% of tank capacity (1250 cc), first removing the cap.

Close the tank plug for transportation.
