Introduction
This Instruction Manual is for your safety. It is also essential to ensure the machine operates to its
maximum efficiency during a long life and returns the highest production profitability.
The BB Type Tube Benders are ‘easy to use’ machines providing quality bending solutions. A
comprehensive tooling range ensures high bend quality on both models according to the capacity
required. All formers can be specified with either counter formers or guide rollers depending on material
and wall thickness..
It is important that the bender is used only for the purpose for which it is manufactured and is not adapted
or modified in any way. Modifications or other uses thereof will invalidate any standard warranties.
The machine is covered by manufacturer’s warranty for a period of 12 months from the date of purchase
against manufacturer defects. The warranty period does not exceed 18 months from the date of delivery
from the manufacturer’s factory.
Warranty covers only defective manufactured parts and/or components that are confirmed as defective by
the manufacturer.
The manufacturer is responsible for the warranty supply only of free-of-charge spares but will not be
responsible for loss of work or consequential damage. Shipping and customs fees for the spare parts must
be paid by the end-user. A Warranty claim does not relieve the Customer from payment obligations.
Non-genuine parts or modifications to the controls or the purpose of use of this machine is dangerous, and
well nullify any claims.
Note: All warranty claims must be made stating the Model, Serial Number and the Manufacture Year of
the machine.

Transporting
During storage and transporting, this machine should be kept covered and dry from inclement weather
conditions. In particular the electrical control panel must be kept dry. When strapping to road transport,
ensure straps are not damaging cables and vulnerable components.
Use a fork truck to move this machine. Check the balance as the centre of gravity may not be where it
appears. Retain the wooded transport skids on the machine until final positioning.
Dispose of packaging safely and in consideration of local environmental expectations. Report any defects
or damage immediately to ________________, or the supplying distributor. Failure to notify prior to
connection to any power supply will render subsequent claims invalid. Clean anti-rust protection film from
steel surfaces and working parts.
Positioning
Locate the machine where it is safe to use in consideration to other personnel in the vicinity and where
materials can safely arrive and depart. It is advisable to be guided by the Provision sand Use of Work
Equipment (PUWER) Regulations, including satisfactory lighting levels.
Site the bender on a level concrete or solid floor in a clean and dry environment, with a minimum of 1.5
metres personnel access all round.
Electrical Connection
ONLY A COMPETENT ELECTRICIAN SHOULD WIRE THIS MACHINE.
INSTRUCTION MANUAL
TUBE BENDER

This machine requires three phases, neutral and
earth. Ensure correct power supply is available,
with a lockable isolator within physical and visual
proximity of the operator. If trailing leads are to be
used, ensure they are suitably protected.
Plug in the foot pedal console.
Check motor rotation and if in reverse to the
motor arrow, change two phases.

Residual Risks
Other general hazards are:
INSTRUCTION MANUAL
TUBE BENDER
PAGE: 6
There remains some residual risk which should be
taken account of before and during the use of this
machine. The operation of the machine results in
materials protruding and moving in an arc beyond
the machine boundary during the bend process.
The residual hazardous events are crushing,
trapping or knocking into persons in the arc
danger zone.
The tooling can be changed for different materials
to be bent. These are manually handled.
The hazardous events are foot injury from
dropped tooling, finger trapping and heavy lifting
injury.

Operator Safety
BEFORE ATTEMPTING TO OPERATE THE MACHINE BECOME FAMILIAR WITH THE CONTROLS AND THESE
OPERATING INSTRUCTIONS.
It is a requirement of the Provision and Use of Work Equipment Regulations (PUWER)  that suitable training
is conducted for control familiarisation. This must include associated health and safety awareness, and
good housekeeping practice.
ONLY SUITABLY COMPETENT PERSONS SHOULD OPERATE THIS tube bender.
Consider and use the necessary personal protective equipment, which should as a minimum include
protective footwear, eye protection, and heavy duty gloves when handling material and replacing mandrel
tools. Do not allow clothing, apparel or hair near moving parts.
Never operate the machine unless all guards and cover supplied are placed and closed. Do not load the
machine or adjust the mandrel whilst the machine is bending.
Always disconnect the power at source when performing maintenance work or making adjustments other
than those necessary for the normal operation of the machine.
Accumulation of scale from tubes, and grease can create potentially dangerous situations. Regularly clean
between operations, ensuring also tools or other objects on the bed or surfaces are correctly stowed
away. Keeping the machine clean and tidy will increase efficiency and productivity, avoid injury, and
reduce the possibility of a breakdown.
If any unusual noise or machine behaviour becomes apparent, switch off, isolate, and seek assistance.

Making the Bend
Maintenance
Maintenance works should only be carried out by sufficiently qualified or competent personnel. Wear
suitable ppe (personal protective equipment). Use correct tools that are in good condition. Clean regularly.
UNDERSTAND THE MANUAL AND MACHINE BEFORE CARRYING OUT MAINTENANCE.
If components have been removed for maintenance, ensure these are correctly reinstated before allowing
an operator to start the machine. Remove any residual oil and debris from the working zone left from
previous operations. Never allow operators to use the machine after maintenance without checking.
INSTRUCTION MANUAL

Press and hold the right pedal for bending. At the
required angle the former will stop.
Press and hold the left foot pedal to return the
folder.
Releasing the foot pedal at any time will stop the
former. Repressing the foot pedal part way
through a bend process will resume the process.
If the foot pedal has been released because of an
emergency, press the Stop and check that dangers
have been eliminated before pressing the foot
pedal to resume

Wiring
Wiring diagrams are available on application. Checking, repairing or amending control wiring is a specialist
task.
Disposal
Current environmental legislation requires owners of machines to consider the environment when
disposing of machinery. This also applies to waste material resulting from the normal operation. All cut
waste material, components, replacement parts, cleaning detritus, and final machine disposal should be
conducted in accordance with accepted environmental policies and established waste and recycling chains
in place. Particular attention should be made to oil disposal after maintenance or final machine breaking.
