1 Safety Tips

1.1 General Safety Tips

Before operating tool make sure to carefully read and
observe this operating instruction.

Generally, the operator of the equipment and/or machinery is responsible for

the equipment’s perfect condition and operation, while observing all necessary

safety regulations. The equipment and/or machinery has been constructed in
accordance with the newest level of technology while recognizing all
necessary safety-related requirements. Nevertheless, while operating the
equipment and/or machinery there is a risk of bodily harm to the operator as
well as damage to equipment and/or machinery and other property.
Operate the equipment and/or machinery only if equipment/machinery

· Is used for the task it was designed for

· is in perfect working condition and safe to use.

It is important to observe the technical data of the equipment, especially in
regards to the environmental temperatures. The designated area of use for this
equipment is clearly described in chapter Designated Equipment Use and
those requirements have to be observed as well. Prerequisite for the safe
conduct and the uninterrupted operation of the equipment, is the knowledge of
the basic safety tips and the safety regulations. Additionally, all current
regulations for a safe operational area, for accident-prevention guidelines of
electrical and mechanical installations, as well as noise suppression demands
must be observed. During any maintenance or repair work, a clean work
surface is recommended. Also, it is not recommended to either eat or smoke
during repair or maintenance. Arbitrary changes made to the equipment, which
alters its designated use, voids the warranty and cancels the manufacturers
liability.

· The tool is not insulated to protect against an electrical power surge.

· It is not recommended to use this tool in explosive hazardous

environments, unless it was specifically designed for such a use.
The operating instruction booklet, especially the safety symbols and safety tips
attached to the equipment or included in the documentation, must be observed
at all times by all persons getting into contact with the equipment.

1.2 General Safety Tips for Pneumatic Screwdriver Spindles

·

Disconnect the tool from the air supply, when changing bits or
when readjusting clutch.

· Do not wear wide clothing or jewelry, for they can be seized by
movable parts. Wear a hairnet if operator has long hair.

· Keep hands off the installed bit or socket.

· Injury is possible, if the driver reacts with an unexpected motion or when

driver is used with a broken bit.

· Keep hands away from holding fixture (if used). This applies especially when
loosening screws in a tight area. There is a risk of squeezing fingers b

etween

holding bracket and tool. Make sure that any bracket used is correctly
installed.

· An unexpected motion of the bit or socket may create a dangerous situation.

· Especially, when operating an impact wrench, it is possible that an injury

occurs, if the bit breaks [flying splinters].

· When using tool with bit-adapter or bit-extension (i.e. Magnetic Bitholder),
make sure, that those items are in good condition and well suited for the
application with this tool.

· When using a screwdriver stand, make sure that the tool is
securely mounted. If no stand is used, make sure to have a solid
stance to absorb the tools’ torque reaction force.

· If you are not able to absorb the torque reaction force, use a
holding fixture or side handle on the screwdriver.

· After turning-off the tool, the bit will continue to rotate [inertia].

· Do not exceed the maximum allowable air pressure. A pressure regulator

has to be installed, which regulates the air pressure before it reaches the
tool.

· Avoid pressure to fall below the minimum allowable air pressure, because
the clutch cannot shut-off safely. This may cause an increased torque
reaction force, resulting in risks to operator, tool or product.

· In case of an interruption of the air supply, make sure to wait until tool has
come to a stand still, prior to reactivating tool.

2 Designated Equipment Use

DEPRAG MICROMAT / MINIMAT-Screwdrivers of straight shape are used for

manual torque

-

controlled assemblies, preferably for vertical applications.

3 Installation

·

Blow out air line and pressure hose, prior to connection it to the tool.

· Make sure, that all air lines have a sufficient cross-section (see technical
data) and hoses must be free of bends and kinks. The hose length should
not exceed 2 meters.

· All DEPRAG Screwdrivers, may be operated either with or without
lubricated air (see paragraph: Maintenance and Upkeep). Best results are
achieved, when machine is lubricated with 1 – 2 drops of oil per 1m3.
When operating with oilfree air, a performance reduction of up to 20%
occurs and maintenance requirements increases!

· Connect the equipment as follows:

a) for standard operation connect equipment to a maintenance unit,

consisting of Filter with condensation reservoir, Regulator and Oiler.
When choosing a maintenance unit, observe air consumption rate for
the tool (see Technical Data).

OUR RECOMMENDATION: The preferred lubricating method for the
screwdriver spindles mounted in fixtures, brackets, machines, etc., each in
connection with a controller, is method b) with Point-of-Use Oiler.

· Check pressure at directly on the machine. The Regulator needs to be

adjusted to an airflow between 5.0 (71 PSI) and 6.3 bar (90 PSI). A higher

pressure leads to increased wear and tear. A lower pressure may lead to
clutch not being able to correctly shut-off the motor.

In regards to air-quality according to ISO8573-1, we recommend:

4 Operation

Unless otherwise requested the driver is preset to max. torque with the
strongest clutch spring installed on the clutch. Adjust clutch to the required
torque value. If necessary, exchange clutch spring. The required torque
adjustment can be checked, using a DEPRAG Torque Wrench or
Dynamometer (see DEPRAG catalogs D 3020 and D 3022). This equipment
can also be used to re-adjust the torque of the Screwdriver.

To operate the clutch, using a clutch spring which either
surpasses or falls below its specified torque range, leads to a
reduction of the torque accuracy.

Push – to start – screwdriver!
The flow pressure should not drop below 5 bar/71 PSI – reduced output!

11

Attention:
The screwdriver is furnished with a reversible motor and a
clutch torquing out in right-hand rotation (so that if you look

at the screwdriver from the air inlet side it rotates clockwise).

Attention:

5 Handling

The operation of the DEPRAG MINIMAT-Screwdriver is very simple. Grip the
Screwdriver as illustrated on the picture “Connection of a DEPRAG MINIMAT-
Screwdriver”.

As soon as you put the bit onto the screw and slightly push the screwdriver
down, it will start running. After reaching the preset torque, the automatic
clutch will disengage and turn off the Screwdriver. The Screwdriver will be
ready for the next operation after lifting it off the screw.

Although the reaction torque you will notice is rather low due to the
ergonomically shaped handle and the immediate effect of the torque-out clutch,
we highly recommend to use an additional torque support, if torque is higher
than 5 Nm (such as a linear stand or lateral handle as per brochure D 3340 E).

The operating direction of reversible Screwdriver models can be reversed by
actuating the reverse button, in order to loosen tightened screws. Tool will also
start after pushing it down. The clutch will be locked in the reverse direction. An
increased reaction torque may occur in the case of screws are hard to tighten
(such as screws with defective thread). The reverse button can be locked by
turning.

Picture: Reversal

· Always disconnect the Screwdriver from air supply prior to changing bits, to
avoid the unintentional start of the Screwdriver, which may result in injuries.

· The screwdriver is equipped with a quick change chuck.

· After pulling the sleeve, the bit may be removed or inserted.

· Make sure to use perfect bits with DIN 3126 – E6,3 (1/4”) external hexagon

end only.

ATTENTION:
Screwdriver will immediately start running once the bit is
pushed, and may cause severe injuries.
