Proper use
The TRUMPF TKF 700-3 bevelling machine is a
portable pneumatic tool used to
• prepare all K, V, X, and Y-shaped welding joints
with different infinitely adjustable bevel lengths
needed for gas and electrical arc-welding,
• form even, non-oxidizing, bare metal bevel edges
and visible edges in steel and aluminium,
• to machine chrome steel and other high-tensile
materials,
• bevel straight and curved edges provided that the
minimum radius of concave curves is 40 mm,
• bevel edges on flat and bent workpieces,
particularly tubes, with an inner diameter of at
least 80 mm, (use supporting roller, order no.
131559),
• bevel edges in both directions, in which bevelling
can be started and terminated anywhere on the
sheet edge,
• bevel edges in normal position (carrier under the
machine) and in "upside-down position" (carrier
over the machine). This is particularly advanta-
geous when bevelling X and K-shaped welding
joints.
Safety instructions
Hazardless working with this unit is only
feasible if you read the operating manual and
safety instructions (red print with the
TRUMPF identity number 125699) completely
and follow the instructions included therein.
Danger of injury
Check the unit, compressed-air tube and
reception coupling before each use.
Have all damaged parts repaired by an
expert.
Danger of injury
Hot chips are ejected from the chip ejector at
extremely high speeds.
Danger of injury
The machine is supported by the workpiece
as long as they are in contact when the
cutting arrangement is "normal" (workpiece
is horizontal). Remember that the entire
weight of the machine must be supported as
soon as it is removed from the machined
edge. (aid: suspension bracket with balancer
or retaining rope).
Always wear safety glasses, ear
protection, protective gloves and
proper footwear when working with
the machine.
• Do not connect the compressed air unless the
machine is turned off.
• Always disconnect the compressed-air tube from
the machine before beginning any work on the
machine!
• Always guide the compressed-air tube back away
from the unit.
• Use only original TRUMPF accessories.
E487en1_2.doc TKF 700 - 3 GB 3
Before initial use
1. Read the chapter on safety.
Safety instructions
2. Mount the handle (the handle is enclosed
separately with the new machine).
3. Check whether the installed cutting tool is
suitable for the material that is to be
machined. Use special cutting tools for high-
tensile sheets (> 400 N/mm²) and aluminium!
Select cutting tool
4. Replace blunt tools.
5. Check the bevel size.
Set the bevel size
6. Adjust the machine to the sheet thickness of
the workpiece.
Sheet thickness
7. The flow pressure of the compressed air
must be 6 bar at the point of extraction.
8. Oil lubrication must take place for the
compressed-air motor.
Maintenance
Operating instructions
Damage to property
Check the tools for wear and the oil
lubrication of the compressed-air motor every
hour.
Never work with a blunt cutting tool,
as this could otherwise overload the machine!
Turning the unit on and off
Fig. 12599
Turning on the unit:
• Push lever 1 forward (releases compressed-air).
• Shift lever 2 (= motor ON).
The motor runs as long as the lever is pressed.
• Release lever 1.
Turning off the unit:
• Release lever 2
(the lever springs back into initial position and the
flow of compressed air is interrupted).
Cooling and lubrication
The cutting results are improved and the service life of
the cutting tool is increased if
• before machining the workpiece
the cutting track is coated with oil.
Recommended for steel:
Punching and nibbling oil, order no. 103387
Recommended for aluminium:
Wisura oil, order no. 125874

Working with the machine
Damage to property
The machine is equipped with an electronic
starting current limiter. Do not, therefore,
begin processing the workpiece until after the
machine has been turned on and has
reached maximum speed!
• Put the machine on the sheet and leave a few
centimetres clearance between the cutting tool
and the edge of the sheet.
• Turn on the machine and push it against the edge
of the sheet as far as possible (piercing).
• Push the machine along the sheet so that the
machine axle is approximately parallel to the
sheet edge. Press the machine against the sheet
edge.
Changing the cutting direction Fig. 13470
The tool (i.e. the cutting direction) can be turned 90°
to the left or right if necessary, e.g. if space is
restricted.
• Loosen the locking lever (15).
• Turn the carrier (1) 90° in the desired direction.
• Close the locking lever (15).
Cutter selection
Two different tool sets may be used to machine
sheets with various tensile strenghts:

Always disconnect the compressed-air
tube from the machine before beginning
any work on the machine!
Ram/carrier part l u b r i c a t i o n

Compressed-air motor l u b r i c a t i o n
Damage to property
Lubrication of the compressed-air motor
is very important. The motor will fail if it
is operated without lubrication even for a
short time.
Install oil lubricating device in the compressed-air
line (e.g. Atlas Copco DIM 25).
Checking the oil supply of the motor
Hold a piece of paper in front of the exhaust opening
in the motor housing while the machine is running.
The oil supply is sufficient if oil stains form.
Reco mmended oils (compressed-air motor lubri-
cation):
• BP Energol RD 80 (-15 to +10° C),
• BP Energol RD-E80 (+10 to +30° C),
• Shell Tellus Oil 15 (-15 to +10° C),
• Torculla 33 (+10 to +30° C).
Cleaning
Clean the filter screwed into the connecting piece
(328) every 10 operating hours in order to prevent
throttling or power loss. (Unscrew, blow out with
compressed air and retighten.)
See the spare parts list for a diagram of items
328 (= "connection") and 329 (= "nipple").
Changing vanes
The performance of the machine decreases if the
vanes are excessively worn.
Vane replacement and all other repair work is to be
carried out by an expert!
Vane set (set of 4) on the rotor of the com-
pressed-air motor. See Item 305 in the spare
parts list for corresponding diagram.
Repairs
Danger of injury
Pneumatic tools conform to the applicable
safety regulations. Repairs may only be
carried out by qualified electricians in order
to prevent unnecessary accidents.
If the machine has been disassembled,
ensure that the shaft (11) is tightened with a
tightening torque of 25 Nm when
reassembling the unit.
