2-001 Safety Information 

2. Safety Information 

Only authorized electricians or electrical specialists may work on the electrical 

equipment. 

The pneumatic and electric connecting lines are to be installed in an orderly manner and 

are to be protected from damage (for example, in cable channels or conduits, or something similar). 

The safety devices, which are included in this shipment, must always be utilized and shall not 

be by-passed or rendered inoperable. 

During service or maintenance work the machine must be turned off and blocked at 

the main electrical switch and to separate the machine from the pneumatic lines 

(for example, by quick coupling). 

Only tools which correspond in accordance with specifications and regulations (for 

example, from the Grass product line program) shall be utilized. 

Only hard metals, or HSS (high speed steel) drills with a total length of 57 mm and a 

shaft diameter of 10 mm may be utilized. 

The drill diameter may be a maximum of 35 mm on the drive spindle and a maximum 

of 12 mm O on all the other bore spindles. 

Shavings may not be blown off, but must be suctioned with the appropriate device. 

Machines shall always be turned off at the main switch when work is finished and 

secured so unauthorized persons cannot start them. 

Keep the workplace and surrounding area clean. 

Messiness and changing work places increase the risk of injury. 

Protect yourself from electrical shocks. 

Utilize the machine only in dry rooms and do not leave the machine outside in the rain. 

Keep unauthorized persons away from the machine. 

Only one person shall operate the machine. 

When working, keep your hands away from the working area of the drill and the 

insertion die arm. 

Wear appropriate work clothing when operating the machine. 

Use a hair net with long hair and do not wear wide or floppy pieces of clothing which 

could become caught in moving machine parts. 

2-002 Recommended Usage 

The Grass hinge drilling machine Unipress, as well as Unipress - Vario, is meant for 

drilling in solid wood and derived wood products. Other uses are not specified; thus, 

the manufacturer is not liable for resulting damages. The user alone assumes all risks. 

The user must conform to the operating instructions when determining appropriate 

usages. 

The machine shall only be operated, serviced and maintained by trained and 

authorized persons. 

The original set-up may not be modified.

2-003 Remaining Risks 

The machine is built according to the present state of technology and known 

safety and technical directives. Still, risks remain for the life and health of the operator 

or of third parties, as well as damage to the machine and other material assets. 

Remaining risks consist of: 

- danger: even when the main switch is turned off the machine moves if the start 

button is activated 

- operation of the machine by unqualified personnel 

- operation of the machine without the required and recommended safety devices 

- inappropriate tooling or improper installation or attachment of tooling 

- the placement of the operator's second hand during drilling, inserting and installing 

movements of machine parts 

- additional people being in the area of the operating machine 

- contact with a turned-off machine which is not in order 

- not maintaining the machine's operation as is described in Chapter 7-0 "Operating 

the Unipress / Unipress - Vario". 

These remaining risks can be prevented by adhering to the information found in 

Chapters 2-0 and 7-0. 

2-004 Safety Devices 

Safety devices, information about dangers, etc. serve to ensure safety and may not, in 

any case be removed or be made inoperable. 

a) The main switch, which can be turned off to prevent unauthorized starting, 

should be turned off during adjustment and set-up processes. 

b) The pneumatic - filter - reducing regulator prevents the machine from 

overloading (see Chapter 4-006). 

c) For thermal overload protection of the motor see Chapter 4-007. 

d) Integrated dust collection to protect personnel from fine dust and simultaneously 

also conditionally protects one from injury by the drill. 

e) Motor first runs when the drill comes into contact with the work piece, and not 

with the pressing of the components

4-006 Machine's Function 


-When the start button is activated, the motor begins. Releasing the start button activates an 

immediate return to the starting (normal) position. 

-The motor turns on about 20 mm before the drill touches the work piece. 

-The pneumatic guide switches over from a set speed to an adjustable work speed about 25 mm 

before the drill comes into contact with the work piece. 

-The motor does not run during insertion. 

-Pneumatic work piece holding clamp is tightened or released by a twist handle. 

4-007 Description of the Safety Devices 

-Thermal excess current release prevents overheating of the motor. 

-Mechanical blocks prevent the bore gear box from descending if the air pressure fails or falls. 

-The suction canal on the gear box prevents utilization of drills which are too large and also 

protects from injury by the drill. 

-Integrated dust suction collection together with the bore gear box prevents unacceptable dust 

emissions. 

-The main switch, which can be turned off, prevents unauthorized starts and ensure safety when 

setting up or doing maintenance work. 

-Dead man's control -- The machine operates only as long as the start button is activated.

8-001 Incorrect Drilling Distance - Adjustment of Scale Illustration 8-001-01 

-Mount gearbox, if necessary, according to point 7-201 or 7-301. 

-Mount a drill bit, if necessary, according to point 7-202 or 7-302. 

-Follow safety information and guidelines. 

-Place a sample work piece. 

-Press against the depth stops on fence. 

-Drill one hole. 

-Measure drilling distance and compare with the set number on the scale. 

-If the numbers are not identical, loosen both screws "1" with 4 mm Allen wrench, move the 

measuring scale to measured number, then tighten both screws "1". 

-Repeat drilling cycle and compare boring distance again with the number on the scale. 

8-002 Incorrect Drilling Depth - Adjustment of Scale Illustration 8-002-01 

-Place the sample material on machine table. 

-Loosen clamp screw "1". 

-Adjust material thickness according to point 7-401. 

-Lift the adjustment screw "2", then place the material "3" , which is as thick as the desired 

drilling depth, underneath. 

-Drill a sample cycle. In this position the drill bit cutters should just drill the material (leaving 

obvious marks on the material). 

-If the drilling is too deep, the adjustment screw must be turned clockwise (1 turn = 1 mm). 

-If the drill cutters do not reach the material surface, adjustment screw "2" must be turned 

counter clockwise. 

-Repeat sample drilling and corrections until the drill cutters drill the material correctly. 

-Remove the work material "3". The material thickness, according to scale "4", must agree with 

the actual material thickness. 

-In case of discrepancies, loosen both screws "5" with 2.5 mm Allen wrench. Move the 

measuring scale until the measured material thickness is identical with the material thickness 

shown on scale "4". Tighten both screws "5".
