Setup & Operation - Hydraulic Clamp Models
CAPACITY
The capacity of your machine is stated on the
specications plate on the frame. This capacity is a
mild steel rating. The capacity for other materials will
vary. For example Stainless Steel is approximately
0.5x the mild steel rating & aluminium is 1.5x the mild
steel rating.
Some machines have a quick adjusting arm with pin positions
marked 0-8. This should represent your clamp gap.
Example: If you are bending 4mm put the pin in position 6.
This must be done on both sides of the machine.
SETTING CLAMP GAP
Set the clamp gap to match your
material thickness.
The clamp gap must be minimum
1.5 x Material Thickness
Example: If 4mm is to be bent, then
the clamp “GAP” must be set to
minimum of 6mm
Each panbrake may have a different
mechanism for adjusting the clamp
gap but you must maintain the 1.5
x Material Thickness to prevent
overload and possible damage.
GAP

FOLDING ARM
BED
6mm POSITION
You may have to use a combination of top clamp adjustment
and apron adjustment when doing thicker material like 6mm
aluminium.
(1.5 x 6mm = 9mm, so you need a total gap of 9mm)
Example: If the top clamp gap is 6mm the apron must be
dropped down 3mm to keep a 9mm total gap.
NOTE: Must release locking bolts before adjusting apron
up / down. Tighten when at correct height.

CORRECT CLAMP OPERATION
If your panbrake has hydraulic clamping it will have a 2 stage travel on the clamp. When the foot pedal
is pressed the clamp will travel down continuously and stop approximately 20mm above the bed.
Release the clamp pedal and press again to complete clamping.
Important - The clamp pressure is set to bend the maximum capacity over the full length. If shorter
pieces, very thin or softer materials are used, there is a possibility that damage can be caused to either
the work piece or the ngers. There are 2 clamping techniques the operator can use depending on
the material used.
Light clamping - The operator can use the clamp foot pedal with caution and only use enough force
required to hold material for bending. It is used when clamping thin aluminium or small pieces of
thicker material.
Heavy clamping - There is a pressure switch that is set to maximum clamping pressure. The operator
can press the clamp pedal until full capacity clamping is achieved. This technique can be used for
bending full lengths of thicker material.
Double check GAP - You must now clamp your job and check the clamp gap to make sure it is
correct.

Caution - There is a minimum “Return length” of
15 x Thickness of Material when bending thicker
material over 1mm. Damage could occur to machine
if return is too short.
Example: If bending 4mm then the minimum return
length must be 60mm.

General Machinery Safety Instructions
1. Read the entire Manual before starting
machinery. Machinery may cause serious injury if
not correctly used.
2. Always use correct hearing protection when
operating machinery. Machinery noise may cause
permanent hearing damage.
3. Machinery must never be used when tired, or
under the influence of drugs or alcohol. When
running machinery you must be alert at all times.
4. Wear correct Clothing. At all times remove all loose
clothing, necklaces, rings, jewelry, etc. Long hair
must be contained in a hair net. Non-slip protective
footwear must be worn.
5. Always wear correct respirators around fumes
or dust when operating machinery. Machinery
fumes & dust can cause serious respiratory illness.
Dust extractors must be used where applicable.
6. Always wear correct safety glasses. When
machining you must use the correct eye protection
to prevent injuring your eyes.
7. Keep work clean and make sure you have good
lighting. Cluttered and dark shadows may cause
accidents.
8. Personnel must be properly trained or well
supervised when operating machinery. Make
sure you have clear and safe understanding of the
machine you are operating.
9. Keep children and visitors away. Make sure
children and visitors are at a safe distance for you
work area.
10. Keep your workshop childproof. Use padlocks,
Turn off master power switches and remove start
switch keys.
11. Never leave machine unattended. Turn power off
and wait till machine has come to a complete stop
before leaving the machine unattended.
12. Make a safe working environment. Do not use
machine in a damp, wet area, or where flammable
or noxious fumes may exist.
13. Disconnect main power before service
machine. Make sure power switch is in the off
position before re-connecting.
14. Use correct amperage extension cords.
Undersized extension cords overheat and lose
power. Replace extension cords if they become
damaged.
15. Keep machine well maintained. Keep blades
sharp and clean for best and safest performance.
Follow instructions when lubricating and changing
accessories.
16. Keep machine well guarded. Make sure guards
on machine are in place and are all working
correctly.
17. Do not overreach. Keep proper footing and
balance at all times.
18. Secure workpiece. Use clamps or a vice to
hold the workpiece where practical. Keeping the
workpiece secure will free up your hand to operate
the machine and will protect hand from injury.
19. Check machine over before operating. Check
machine for damaged parts, loose bolts, Keys and
wrenches left on machine and any other conditions
that may effect the machines operation. Repair and
replace damaged parts.
20. Use recommended accessories. Refer to
instruction manual or ask correct service officer
when using accessories. The use of improper
accessories may cause the risk of injury.
21. Do not force machinery. Work at the speed and
capacity at which the machine or accessory was
designed.
22. Use correct lifting practice. Always use the
correct lifting methods when using machinery.
Incorrect lifting methods can cause serious injury.
23. Lock mobile bases. Make sure any mobile bases
are locked before using machine.
24. Allergic reactions. Certain metal shavings and
cutting fluids may cause an ellergic reaction in
people and animals, especially when cutting as the
fumes can be inhaled. Make sure you know what
type of metal and cutting fluid you will be exposed
to and how to avoid contamination.
25. Call for help. If at any time you experience
difficulties, stop the machine and call you nearest
branch service department for help.
Machinery House
requires you to read this entire Manual before using this machine.

Manual Panbrake Safety Instructions
1. Maintenance. Make sure all moving parts are
locked down before any inspection, adjustment or
maintenance is carried out. Place a block of timber
between the Top Tooling and bed to help save hand
or fingers from being crushed.
2. Panbrake Condition. Panbrake must be maintained
for a proper working condition. Never operate
a Panbrake that has damaged or worn parts.
Scheduled routine maintenance should performed on
a scheduled basis.
3. Tooling Condition. Never operate a Panbrake with
damaged or badly worn tooling. Replace if required.
4. Hand Hazard. Do not insert or extend your hands
in between bending tools, under any circumstances,
while the machine is in operation mode. Serious
injury can occur.
5. Gloves & Glasses. Always wear leather gloves and
approved safety glasses when using this machine.
6. Work area hazards. Keep the area around the
Panbrake clean from oil, tools, objects & chips. Pay
attention to other persons in the area and know what
is going on around the area to ensure unintended
accidents.
7. Guards. Operate machine only with all protective
devices and guarding.
8. Material. Do not over load the machines capacity by
using material which is too thick or hard.
9. Warning Labels. Take note of any warning labels on
the machine and do not remove them.
10. Support arms. Do not use support arms for
intermediate storage of workpieces.
11. Operation. During the bending process, the
workpiece may leap up. Therefore, the material
must be handled carefully.
12. Secure Panbrake. Make sure you bolt and the
machine down so it is secure when in operation.
13. Heating Material. Heating metal with a torch while
the metal is in the panbrake will weaken the fingers.
14. Pinching. Prevent pinching by lowering the
panbrake fingers when not in use.
15. Call for help. If at any time you experience
difficulties, stop the machine and call you nearest
branch service department for help.
