2.1 Correct use
Warning
Risk of injury!
For processing and materials, only use machines which are
named in "Correct use".
The TRUMPF bevelling machine TruTool TKF 700 is an electric
hand tool used for the following applications:
•Preparation of all of the K-, V-, X- and Y-shaped welding
grooves usual for gas and electrical fusion welding with various
continuously-adjustable angles of bevel and continuously-
adjustable lengths of bevels.
•Forming of uniform, oxide-free, bright metallic welding bevel
edges in steel and aluminium.
•Machining of chromium steel and similar high-tensile materials.
•Bevelling of straight and curved edges insofar as the minimum
radius with inner curves is at least 40 mm.
•Bevelling of edges on flat and crooked workpieces, particularly
in connection with tubes when the inside diameter is at least 80
mm in size. (supporting roller, Material No. 131559).
•Bevelling of edges in both directions, whereby the bevelling
can begin and end at any give point on the sheet edge.
•Bevelling of edges on large, bulky workpieces, for which the
bevelling machine is guided as a hand-held device.
•Machining of small workpieces, for which the bevelling
machine is kept in a stationary position. A workstation is used
for this purpose (Order No. 977764).
•Bevelling of edges in normal position (carrier underneath the
machine) and in "upside-down position" (carrier above the
machine), which is particularly advantageous with the bevelling
of X- and K-welding grooves.

3.6 Configuring workstation (optional)
Warning
Risk of possible injury from sharp blades!
Do not reach into the area which is covered over by the hand
protection device.
The workstation in which the TruTool TKF 700 bevelling machine
can be fastened is used for machining small workpieces.
This workstation, which stands on a non-skid support, must
screwed down tightly to a table through mounting holes.
Support area: 220x450 mm, height approximately 220 mm.
The machining of small workpieces in the workstation
Fig. 15496

E459EN_05.DOC Tool assembly 15
Mounting and aligning the machine in the
workstation
1. Rotate the machine carrier into the correct position.
2. Fasten the machine in the workstation with the help of the
screw (110) (wrench can be found among the accessories).
3. Loosen the two clamping levers (46).
4. The plate (45) in which the machine is held can be adjusted
only by turning the star grips (49).
5. This will cause the pressure die to be repositioned in relation to
the strips (41) and (42). (Pressure die = hardened support
piece on which the sheet edge to be machined is slid along
during the work process).
6. Set chamfer size and sheet thickness at the two knurled nuts
(31) and (34) on the machine.

the strips (41) (42).
9. Lay flat part of sheet with straight edge on the strips (41) (42).
10. Turn star grip (49) until the pressure die is up against the sheet
edge.
11. Turn both star grips (49) by approximately 1/4 of a revolution
further to the right, respectively, and lock with the knurled
counter nut (48).

E459EN_05.DOC Tool assembly 17
12. Clamp the plate (45) tightly with the two clamping levers (46).
13. The workpiece will lie on the plate (45).
Note
Hold the work piece during machining in such a way that the
surface lies on the plate (45) and the sheet edge lies on the strips
(41) (42).

18 Operation E459EN_05.DOC
4. Operation
Caution
Damage to property possible due to too-high network
voltage!
Damage to the motor.
Check the power supply. The power supply must correspond
to the information on the machine type plate.
Warning
Danger of injury possible due to improper handling!
When working with the machine, always ensure that it has a
secure base.
Never touch the tool while the machine is running.
Always guide the machine away from the body while working.
Do not work holding the machine above your head.
The appliance may switch off prematurely when affected by
electromagnetic disruptions. The appliance will resume operation
when the faults have been cleared.
If the motor temperature is too high, the motor will switch off. The
red indicator light (LED) with the motor lights up.
Allow the machine to run in idle until it has cooled down.
The machine can be operated again normally after it has cooled
down.
Note
Check the cutting edge of the blade hourly.

1 On/Off switch
Move the On/Off switch to the front.
Note
The cutting result is improved and the service life of the cutting tool
increased if the cutting track is coated with oil before machining the
workpiece.
Material Oil
Steel Punching and nibbling oil, Order No. 103387
Aluminium Wisura oil, Order No. 125874
Recommendation for oil
1. Do not move the machine towards the workpiece until full
speed has been reached.
2. Machine/process the material.
–Place machine on the sheet and at first maintain a few
centimetres clearance between the blade and the sheet
edge.
–Carefully slide the machine as far as possible against the
sheet edge "piercing".
–Slide the machine along the sheet in such a way that the
machine axis is roughly parallel to the sheet edge.
–Press the machine against the sheet edge while doing so.
Move the On/Off switch to the rear.
