Store the cleaning cloths and other combustible
material in sealed metal containers. These containers
must be disposed according to local, national and
regional provisions.
When the appliance is operated the air pressure MUST
NOT exceed 6.3 bar. Use a pressure regulator that will
reduce the air pressure to 6.3 bar.
ALWAYS use the appliance in a safe distance from
people and animals.
Make sure the speed of rotating of accessories parts
corresponded to the speed of rotating of the impact
tightener or was higher.
Before starting
Air supply
Important information on the appliance can be found in
model specifications.
Lubricate the appliance before putting it into
operation (see the Maintenance part).
Assembly
Always disconnect the air supply hose when you want
to assembly socket nuts or extensions on the
appliance or disassemble them from the appliance.
Operation
Safety notice!
Wear protective glasses! Wear ear
protectors!
Always empty water from the compressor tank and
blow condensation out of the air hose before everyday
operation.
Now start your compressor. The maximum service
pressure of air is 6.3 bar.
The power (torque) of impact tighteners under primary
working conditions is especially determined by three
factors:
a) service pressure used
b) time of working step on the threaded joint. A normal
work time for a threaded joint is 3-5 seconds on
average.
c) setting of the switching lever, in relation to the
threaded joint in proportion to the impact time.
Due to the use of threads and materials of various
hardness there is an increased friction, which causes
higher torque without the thread being tightened more
firmly. At rust-stained threaded joints, use appropriate
agents dissolving rust before using the impact
tightener. If the threaded joints still fail to unloose after
3 to 5 seconds of impact time it is necessary to use a
one lever bigger impact tightener. Do not overload the
impact tightener above the specified power limit as it
dramatically shortens the service life of the appliance.
NOTE: The tightening torque on the threaded joint is
directly connected with the thread firmness, appliance
revolutions, condition of the power socket nuts used
and time of use of the impact tightener at the given
screwing. Use as direct and simple connection
between the appliance and power socket nut as
possible. Any extra connection and extension absorb
and reduce the power.

Maintenance and treatment
Lubrication
1. Disconnect the impact tightener from air
supply.
2. Add 4-6 drops of GUDE pneumatic oil, Order
No. 40060 (we recommend the GÜDE mist
lubricator, Order No. 41354) or corresponding
oil to air inlet with the starter being pressed.
3. Now reconnect the appliance with air supply
and leave it run for app. 30 seconds so that
the surplus oil flowed out.
This lubricating process corresponds to the reduction
of humidity, dust and impurities that are in course of
time deposited, when the appliance is used, in each
compressor and thus reduce its power. This is best
prevented by integrated oil tanks.
Safety notice! Leaked oil can cause
serious injuries. Cover the top of oil outlet
after cloth greasing and leave the
appliance run for several seconds so that
surplus oil could safely flow out. Keep the
cloth in a safe distance from the rotary
parts!
The air hose must be disassembled and larger volume
of pneumatic oil poured to the air inlet each three
months or if the impact tightener is used only
sometimes. Reconnect the air hose and leave the
impact tightener run for app. 30 seconds so that the
compressor engine was cleaned. Follow the lubrication
instructions after cleaning.
Failure removal
Problem
Possible cause
Solving the problem
Insufficient air pressure
Check the air pressure on the air
inlet. It must be 6.3 bar.
Air pressure set low
Increase the pressure to 6.3 bar
Impact tightener must be oil-
lubricated
See the Lubrication
Impact tightener must be cleaned
See the Maintenance
Impact tightener is not working or is
running slowly
Air hose not tight
Tighten all hose screwed joints
