2-001 Safety Information

Only authorized electricians or electrical specialists may work on the electricalequipment.The pneumatic and electric connecting lines are to be installed in an orderly manner andare 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 notbe by-passed or rendered inoperable. During service or maintenance work the machine must be turned off and blocked atthe 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 (forexample, 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 ashaft diameter of 10 mm may be utilized. The drill diameter may be a maximum of 35 mm on the drive spindle and a maximumof 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 andsecured 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 whichcould become caught in moving machine parts.

2-002 Recommended Usage

The Grass hinge drilling machine Unipress, as well as Unipress - Vario, is meant fordrilling 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 appropriateusages.The machine shall only be operated, serviced and maintained by trained andauthorized 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 knownsafety and technical directives. Still, risks remain for the life and health of the operatoror 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 inChapters 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

2-005 How to prevent damages:

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