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

The unit may only be used with a chip

deflector (hand protection).

Check the unit, compressed air tube and

reception coupling before each use.

Have all damaged parts repaired by an

expert.

Always wear safety glasses, ear

protection, protective gloves and

proper footwear when working with the

unit.

• 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.

• Only use original TRUMPF accessories.

Before putting the unit into service

1. Read the chapter on safety.

Safety instructions

2. Check whether the installed cutters are suitable

for the material that is to be machined. For

high-tensile sheets (> 400 N/mm²) and with

sheet thickness > 1.5 mm special cutters

should be used!

Cutter selection

3. Turn blunt cutters over or replace.

Replacing cutters

4. Check whether the cutting clearance is suitable

for the sheet thickness that is to be machined.

Cutting clearance

5. Check if the height adjustment of the moving

cutter blade is suitable for the sheet thickness

to be processed.

Setting the height of the moving cutter

blade

6. The flow pressure of the compressed air must

be 6 bar at the point of extraction.

7. 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 blunt tools!

(the compressed-air motor may stop).

Turning the unit on and off

Fig. 15480

Turning on the unit: Press lever 1 backwards (=

motor ON). The motor runs as long as the lever is

pressed.

Turning off the unit: Release lever 1 (the lever

springs back into initial position and the flow of

compressed air is interrupted).

Damage to property

Do not begin machining the workpiece until

after the unit has been turned on and has

reached maximum speed!

1 Lever

E322en1_2.doc S 350 - 3 GB 3

Guide the unit towards the sheet surface at an angle

of 80° to 90° (figure).

Fig. 15481

Sharp cutters always cut well and are easy on the

unit. Always turn over or replace the cutters in good

time.

Cutting radii: Do not tilt the unit and work with minimal

feed.

Work upside down with the fixed blade carrier pointing

upward when cutting along the edge, particularly

during precision cutting along a scribed line.

Cutter selection

Moving cutter blade (top cutter) and fixed cutter blade

(bottom cutter) have the same shape and are mutually

(top or bottom) interchangeable. All cutters have 2

cutting edges. These are not regrindable "double-

reverse blades". 2 different cutter types may be

selected from the following table according to the

thickness, tensile strength and type of workpiece that

is to be machined:

thickness are being processed.

** Cutter type "Cr" = chrome-steel cutter with opti-

mised cutter geometry, suitable for steels

> 400 N/mm² and sheet thicknesses > 1.5 mm

( ) can be used, but subject to increased wear!

Damage to property

If the cutter selection is not carried out

correctly in accordance with the table,

• the cut quality can be strongly affected

•

can result in the overloading of individual

tools when processing thick sheet

(especially with chrome-steel).

Risk of fracture!

It is therefore urgently recommended that

tools be used according to the specifications

found in the table.

Replacing cutters

Danger of injury

Always disconnect the compressed-air

tube from the machine before beginning

any work on the machine!

Turn over or replace moving cutter blades

• Turn twist grip (27) to level "o" (moving cutter blade

in lower position).

• Release fixing screw (1s).

• Turn moving cutter blade (5s) by 180° and remount

(or mount a new cutter blade).

• Screw in fixing bolt (1s) and tighten up.

Turn fixed cutter blade over or replace

• Release fixing screw (1t).

• Turn fixed cutter blade (5t) by 180° and retighten

fixing bolt (1t).

Caution: Note cutting clearance!

Cutting clearance

Cutting clearance "a" should ideally be

0.2 x the sheet thickness to be cut

Examples:

Sheet thickness "s" (mm) 0.5 1.0 2.0 3.0 3.5

Cutter spacing =

cutting clearance "a" (mm)

0.1 0.2 0.4 0.6 0.7

Adjusting the cutting clearance

• Make sure that the moving cutter blade (5s) is in

the bottom dead centre (by repeated, light

"tapping" of the switch).

• Disconnect the compressed-air tube from the

machine!

• Gently tighten up the fixed cutter blade (5t) with

fixing screw (1t).

• Adjust the fixed cutter blade (5t) to the desired

cutting clearance using the adjusting screw (2)

(check with feeler gauge).

• Tighten up fixing screw (1t).

• Tighten the adjusting screw (2) slightly.

Height adjustment of the moving

cutter blade

In order to achieve optimum cutting performance

when cutting metal sheets and on curves, the spacing

between the moving cutter blade and the fixed cutter

blade (plunging depth into sheet) must be adjusted to

the cutting task and the sheet thickness.

See Fig. 14845

Height adjustment of the moving cutter blade

Height adjustment of the moving cutter blade Fig. 14845

By turning the grip (27) the height clearance between

moving and fixed cutter blade is altered.

The operator can actuate this height adjustment when

the unit is switched off and also during a cutting pro-

cedure, i.e. when the unit is running. The cutting per-

formance can be optimised according to application

by means of this infinitely adjustable clearance

adjustment.

Marking points are fitted on the twist-grip (27), which

should be set for s h e e t t h i c k n e s s and

a p p l i c a t i o n in accordance with the following

table.

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.

Recommended oils (compressed-air motor lubrication):

• 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 (4) on the rotor of the compressed-air

motor. See Item 305 in the spare parts list for

corresponding diagram.

Attention: When mounting the motor housing, make sure

the chip deflector (item 34) does not cover the air exhaust

holes.

Repairs

Danger of injury

Pneumatic tools comply with the relevant safety

regulations. Repairs may only be carried out by

qualified electricians in order to prevent

unnecessary accidents.

If the height adjustment of the moving cutter

blade fails,the machine must be sent for repairs

to a TRUMPF Service center.

Use only o r i g i n a l s p a r e p a r t s.

Please note the specifications on the output plate.
