2-001 Safety Information 

- It is the responsibility of the machine owner or his/her agent to ensure that machine operators are properly 

trained to operate the machine. 

- Any work on the electrical equipment may only be performed by licensed electricians or electrical engineers. 

- The pneumatic and electrical connection lines must be properly laid and protected against damage (e.g. in 

cable ducts or similar). 

- The safety devices provided must always be used in accordance with section 2-004, and must not be 

bypassed or rendered inoperable. 

- During service or maintenance work, the machine used must always be disconnected from the power 

supply (pull out the plug) and from the compressed air supply (e.g. by means of a quick coupling). 

- Before changing a tool or gearbox, or before working in the area of the drill, always set the main switch on 

the switchgear cabinet to “0” (i.e. OFF). 

- Only use suitably strong and sturdy tools which meet the appropriate specifications and regulations (e.g. 

those available from Grass GmbH). 

- Only use tungsten carbide or high speed steel drill bits with a total length of 57mm and a shank diameter of 

10 mm. 

- The drill bit diameter should only have a maximum of 35mm on the drive spindle and a maximum of 16 mm 

on all other spindles. 

- Before operating the machine, check that all safety devices are intact and fully functional. Damaged parts 

should be replaced with authorised parts only. 

- Exercise particular caution in the case of large workpieces which project beyond the machine. It is 

advisable to fit a larger support or to use additional supports for such workpieces. 

- Shavings should not be blown off the machine but should be vacuumed using the appropriate device. 

- Always turn the machine off at the main switch when you have finished working and secure it so that 

unauthorised persons cannot restart it. 

- Keep the workplace and the surrounding area clean and tidy because messy, disorganized workplaces 

increase the risk of injury. 

- Protect yourself against electric shocks. 

- Only operate the machine in dry areas. Never leave the machine outside, especially in the rain. 

- Keep unauthorised persons away from the machine. 

- Only one person at a time may operate the machine. 

- When working, keep your hands away from the operating zone of the drill and the insertion die arm. 

- Always wear appropriate work clothing when operating the machine. 

- Wear a hair net if you have long hair and do not wear wide, baggy clothing which might become caught in 

moving parts. 

2-002 Intended Use 

2. SAFETY INFORMATION

purposes described in section 7-4. The manufacturer cannot be held liable for any damages arising from 

failure to adhere to the intended use of the machine. The user shall be solely responsible for any and all 

risks inherent in the use of the machine for any purpose other than those explicitly stated in this manual. 

- Adherence to the intended use includes compliance with the instructions contained in this manual. 

- The machine may only be operated, serviced, maintained and repaired by authorised, suitably trained 

personnel. 

- Original machine equipment may not be modified in any way without the prior express written consent of

2-003 Risks pursuant to EN 292-2 

The design and construction of the Flexipress drilling and insertion machine is based on state-of-the-art 

technology and recognized safety standards. Its use may nevertheless give rise to risks to life and limb of 

the user or of third parties, as well as to the equipment or other property. 

Residual risks exist: 

- if the start button is actuated, caution: the machine can still move, even if the main switch is turned off; 

- if the machine is operated by unqualified personnel; 

- if the machine is operated without the required safety guarding; 

- if incorrect tooling is used or if tools are incorrectly fitted or secured; 

- if the operator positions his second hand incorrectly when moving machine parts are performing drilling or 

insertion operations; 

- if other person(s) is/are present in the vicinity of the machine when it is in operation; 

- if a person contacts a machine which has not been turned off and secured in the proper manner; 

- if the procedures described in section 7-0 “Operating the Flexipress” are not followed; 

- if control elements fail. 

These residual risks can be reduced by adhering to the instructions contained in sections 2-0 and 7-0. 

2-004 Safety Devices 

Safety devices, warning notices, etc. are provided for the safety of the operators and may not, under any 

circumstances, be removed, damaged or rendered inoperable. 

- The main switch which can be locked off to prevent unauthorised start-ups and to switch off the machine 

during setting up and adjustment operations. 

- The pneumatic filter/pressure reducer prevents the machine from overloading (see pneumatic diagram, 

section 4-006) 

- Thermal overload protection on the electric motor (see electrical wiring diagram, section 4-007). 

- A pneumatically monitored check valve directly mounted on the main cylinder prevents the machine from 

descending in the event of a drop in air pressure. The valve is not opened until the start button is activated 

(see pneumatic diagram, section 4-006) 

- The motors do not run until the appropriate start button is actuated. Once the start button is released, 

i.e. once the pneumatic drilling depth stop is activated on the vertical drilling head, the motors switch off 

after a time delay. This time delay can be set on the switchgear cabinet. 

- The motor does not run during the insertion process. 

- The integrated dust collection system protects operating personnel against fine dust and also acts as a 

guard to prevent contact with the drill bits.

4-004 Description of Operator Controls Fig. 4-004-01 

Flexipress Fig. 4-004-01 

1 Start button for the vertical movement 

As long as the start button is kept pressed, the drilling head will move downwards until it comes to rest 

on the drilling depth stop and/or the pneumatic cylinder has executed the complete stroke. 

2 Selector switch to clamp workpiece for horizontal drilling 

Left position = workpiece released Right position = workpiece clamped 

3 Start button for the horizontal movement 

As long as the start button is kept pressed, the drilling head will move forwards until it comes to rest on 

the drilling depth stop ans/or until the pneumatic cylinder has executed the complete stroke. 

4 Main switch, located on the switchgear cabinet 

Warning: This switch only deactivates the electric motors - not the pneumatic control 

5 Insertion die arm which holds the insertion dies 

6 Knurled screw for adjusting drilling depth for the vertical drilling head 

7 Locking pin for pivot movement of vertical drilling head 

8 Hand wheel for adjusting setup distance for vertical drilling head 

9 Height adjustment of the horizontal drilling head 

4-005 Machine Functions 

Vertical drilling head: 

Pressing the start button “1”, Fig. 4-004-01, activates the pneumatic cylinder and moves the drilling head 

downwards. 

The air is released from the cylinder by means of the non-return throttle valve 11, Fig. 4-006-0X, and the 

actuated pneumatic roller valve 12, Fig. 4-006-0X, or the non-return throttle valve 13 Fig., 4-006-0X. 

The downward movement continues as long as the start button is kept pressed. This movement ends when 

the depth set on Item “6”, Fig. 4-004-01, is reached. 

If the start button is released, the vertical drilling head will move upwards. 

Horizontal drilling head: 

Before horizontal drilling can be performed, the workpiece must be clamped with the insertion die arm swung 

downwards. For this purpose selector switch “2”, Fig. 4-004-01, must be turned to the right. Pressing start 

button “3”, Fig. 4-004-01, for horizontal drilling will cause the horizontal drilling head to move forwards until 

the drilling depth set with drilling depth stop “12”, Fig. 4-004-01, is reached. Releasing the start button will 

make the horizontal drilling head move back again.

7-301 Setting the Vertical Drilling Depth (Material Thickness) Fig. 7-301-01 

Tools required: None 

With the Flexipress it is the thickness of the workpiece to be drilled and not the actual drilling depth which 

has to be set. The indicator is set to give a drilling depth of 13 mm when drill bits with a length of 57 mm are 

used. 

To calculate the setting: +Drill bit length e.g. 57 mm 

- Machine constant 44 mm 

+ Material thickness e.g. 35 mm 

- Required drilling depth e.g. 16 mm 

= Setting 32 mm 

- Loosen star knob “1” by hand. 

- Turning knurled screw “2” clockwise reduces the drilling depth by 1 mm per turn. 

- Tighten star knob “1”. 

7-302 Setting the Vertical Drilling Setup Distance Figs 7-302-01/02 



- Open and pull out lever “1”. 

- Turning hand wheel “2” clockwise decreases the vertical drilling setup distance. 1 turn corresponds to 2 

mm. The spacing from one bore hole to the next in the index plate corresponds to a difference in vertical 

drilling setup distance of approx. 0.066 mm. Read off the setup distance on digital indicator “3”. When 

adjusting the setup distance, always adjust from a larger to a smaller value - to compensate any play in the 

threaded spindle. Adjustment from 15 mm to 17 mm is performed in 2 steps: a) from 15 to 20 and b) from 

20 to 17 

- Engage lever “1” into one of the bore holes in the index plate and fold down.

7-303 Setting the Vertical Drilling Speed Fig. 7-303-01 



The Flexipress operates with a continuously adjustable feed speed and a continuously adjustable operating 

speed. 

When the vertical drilling head moves downwards, air from the pneumatic cylinder is released by means of 

the throttle “1” and escapes unimpeded via the activated roller valve (item 12 on the pneumatic diagram). 

The feed speed is set on this throttle “1”. Turning it clockwise decreases the feed speed. 

The pneumatic valve (Item12 on the pneumatic diagram) is deactivated approx. 80 mm above the bottom 

end position of the vertical drilling head. Air must now also be released via the throttle “2”. The operating 

speed is set with this throttle. Turning it clockwise reduces the operating speed. 

The following general rule applies for the operating speed: 

The harder a workpiece, the slower the operating speed should be; 

the less the tool cuts, the slower the operating speed should be. 

The air released by the vertical cylinder is collected and expelled via the exhaust arbour in the gearbox (item 

24 on the pneumatic diagram) to blow out shavings and chips towards the collection duct. 

The upward movement of the vertical drilling head is always performed at full speed.

7-501 Setting the Side Stops Fig. 7-501-01 


Loosen the screw “1” with 5 mm Allen key “2“ by turning it counterclockwise. 

Slide the stop “3” to the required dimension. The read-off edge “3” is the edge of the side stop. 

Tighten screw “1” by turning it clockwise. 

To prevent errors between the left and right, we recommend using a stop adjustment gauge for the second 

side. 

The stop adjustment gauge and the zero point retainer “4” are included in the basic equipment. 

7-502 Using the Stop Adjustment Gauge Figs 7-502-01/02/03/04 



- After setting the side stops “A” and “B” for right side, set the left side (e.g. when mounting hinges on left 

and righthand doors) 

- Insert pin “1” of side stop adjustment gauge “8” into bore hole “2” of zero point gauge “3” 

- Loosen flap screw “4”, slide adjustment ring “5” against stop catch “6” of side stop “A”. Tighten flap screw 

“4” in the figure. Important: Flap screw “4” must point upwards. If necessary, use more adjustment rings “5”. 

- Press down all stop catches “6” 

- Swing side stop adjustment gauge “8” through 180º to the left side, Fig. 7-502-03. 

- Loosen a stop “C” on the lefthand side. Slide stop stop “C” against the adjustment ring “5” until stop catch 

“6” lines up with the adjustment ring. Tighten side stop “C”. 

- If necessary, use more stops. 

For hole patterns which are used repeatedly, we recommend having a side stop adjustment gauge for each 

hole pattern and replacing the flap screws with set screws. 

This will then allow you to reproduce the required side stop settings exactly on both sides by means of the 

side stop adjustment gauge.

7-503 Using the Index Gauge When Drilling Lines of Holes Figs 7-503-01/02 


Index gauge 

The index gauge is used to set the distances between the side stops in multiples of 32 mm for line drilling 

operations. 

- Set the first side stop “A” to the required dimension (64 mm on the right side of the workpiece, 480 mm on 

the left side of the workpiece + the required start of the hole line pattern from the edge of the stop) 

- Place index gauge “C” with edge “C1” at the first side stop “A”, edge “A1” 

- Select the recess in the index gauge to suit the number of drill bits to be used for the line 

- Loosen the next side stop “B” and slide the side stop (edge “B1”) against edge “C2” of the index gauge. 

- If more stops are needed, place the index gauge on stop “B” and set another stop in the same way. 

In order to avoid adjustment errors and maintain accuracy between the left and right, we recommend setting 

the stops on the second side with a side stop adjustment gauge. 

Use of the side stop adjustment gauge is described in section 7-502. 

7-504 Setting/Mounting the Pendulum Stop (Accessory) Fig. 7-504-01 

Tools required: 8 mm fork wrench 

Test piece 

1 drill bit, 57 mm long 


To mount the pendulum stop: 

Remove all the stop pins “4” in the centre of the machine table. 

Place pendulum stop “5” against the fences “7” and insert the two pins “6” into the bore holes of the 

pendulum stop and the fences. 

To set the pendulum stop: 

Loosen lock nut “1” with 8 mm fork wrench. 

Adjust set screw “2” in the required direction with the 8 mm fork wrench. 

Drill a test hole as described under section 7-605, check the dimension. If necessary, repeat the setting 

operation and test drill again until the correct dimension is obtained. 

Do the same for the second side of the pendulum stop. 

If different dimensions are required, e.g. for back panels for Systems 6000 and 7000, 2 pendulum stops can 

be used. 

Once the setting operation has been successfully completed, make sure that the top side of pendulum “3” is 

always facing upwards, otherwise you may get variances when drilling. 

To remove the pendulum stop: 

Remove both stop pins “6”, remove pendulum stop and re-insert the standard pins “4”.

NOTES 



8-103 The Vertical Feed Speed Cannot be Adjusted 

Possible causes: 

- Non-return throttle valves, item 11 and/or 13 on pneumatic diagram, are defective. 

- Reversing valve, item 12 on pneumatic diagram, is defective. 

- Reversing valve, item 12 on pneumatic diagram, is not activated by the switching cam. 

Whichever is the case, request the assistance of a pneumatics specialist or Grass service engineer. 

8-104 The Vertical Drilling Head Motor Does Not Run 

Pneumatic causes 

- Is the insertion die arm raised to its uppermost position? (Pneumatic position monitoring) 

- Remove pneumatic hose “V” from non-return throttle valve “11” on the switchgear cabinet, Fig. 4-002-06, 

and check whether air is released at the pneumatic hose when the vertical drilling head start button is 

pressed. If there is no air, this means there is a problem with the pneumatic control system. 

Electrical causes 

- Is the machine plugged in? 

- Check the fuses on your factory distribution panel. 

- Is the main switch turned on? 

- Turn off the main switch, open the switchgear cabinet with the key and press the red buttons on the 

thermal overcurrent relays, check automatic fuses or blowout fuse, close switchgear cabinet, turn the main 

switch back on 

- Electric motor defective 

Mechanical causes 

- Turn off the main switch. Check whether the gearbox can be turned manually by rotating one of the 

spindles. This should turn the fan wheel in the electric motor. If not, the gearbox is mechanically damaged.
