Noise and Vibration Declaration Statement
Sound Pressure level (dBA) =75 ± 3 re. PN8NTC1 .2 Test code
Vibration
Level (m/s) = <2.5 re ISO 8662/7
These declared values were obtained by laboratory type testing in
compliance with the stated standards and are not adequate for use
in risk assessments. Values measured in individual work places may
be higher than the declared values. The actual exposure values and
risk of harm experienced by an individual user are unique and
depend upon the way the user works, the workpiece and the
workstation design, as well as upon the exposure time and the
physical condition of the user.
We, Desoutter, cannotbe held ltab\e for the consequences of using
the declared values, instead of values reflecting the actual exposure,
in an individual risk assessment in a work place situation overwhich
we have no control.

PT250-T Instructions
Desoutter Limited Eaton Road Heme! Hempstead Hertfordshire HP2 7DR England
1. Use an air supply which is: water free, filtered and regulated to 6.3
bar.
2. Use impact quality sockets, in good condition.
3. Eye and ear protection must be worn.
4. Disconnect the air supply before handling the socket, adjusting
the impulse unit or dismantling the tool.
5. Keep loose articles of clothing and IOfllJ hair ifflilj from the tool
when in use.
6. Hold the tool correctly; be ready to counteract normal or sudden
movements -have both hands available.
7. Immediately after adjusting the impulse unit, check for correct
operation.
8. Do not use with reduced air pressure or in a worn condition: the
impulse unit may not operate, resulting in sudden rotation of the
tool handle.
9. Ensure that the workpiece is properly supported.
1
O. Must not be used in explosive atmospheres.
11. Powertoolsare not insulated from coming into contact with electric
power.
VITON RUBBER COMPONENTS
IN THE EVENT OF FIRE, HIGHLY TOXIC COMBUSTION
PRODUCTS (INCLUDING HYDROGEN FLUORIDE) CAN
CAUSE SEVERE PERSONAL INIURY.
DO NOT HEAT ABOVE 300°C.
DO NOT USE A HEAT GUN TO DISMANTLE PULSE UNIT.
STATEMENT OF USE
This product is designed for installing and removing of threaded fasteners.
No
other use permitted.
LUBRICATION
This tool is designed to operate on a dry air line. It can also operate on a
lubricated air line. Service lite,
and performa.nce may be enhanced when
a lubricated air line is used.
Printed in England
WEIGHT
4.3 kg.
ACCESSORIES
A range of accessories are available and suitable items should be selected
from the Accessories Catalogue.
AIR QUALITY
-For optimum performance and maximum machinelife we recommend
use of compressed air with a dew point between +2°C and+ 10°c.
- Use a separate air filter installed as do~ as possible to the machine.
Blow out the hose before connecting.
There
is no disadvantage for the operation of the machine if the
compressed air contains a small quantityofoil (1-5 mg/m3). Air quality
according
to ISO/TC 118, qualityclass 2.4.3. or 3.4.4. is recommended.
-With extremely dry air, service life of vanes may be reduced.
Compressed air connection and hose size - see the spare parts list
Make sure that the hose size is correct
SETIING OF TIGHTENING TORQUE
The torque is adjusted by setting the adjusting screw with a groove. Do
not mix up the adjusting screw and the oil filling plug with hex. key hole.
The adjusting screw is to be turned clockwise to increase the tightening
torque.
Note: It is recommended to start at min. torque setting - when the
adjustment screw is screwed out approx. 7 turns from the bottom
position. Do not screw out more than 8 b.Jrns from max.
Min.
torque setting:
Set
the adjusting screw at min level . At hard joints and min.
setting, reduced air pressure will improve
the accuracy.
Check
the tightening torque given on the joint in question.
The adjusting screw is accessible through the hole in the housing. If
necessary, turn the outgoing spindle.
After adjusting do not forget to a~semble the plug in the hole in the
housing.
CHECKING THE OIL IN THE PULSE-UNIT
The oil level shall be checked after f!Very 50,000 tightenings, see Page 7.
If the tightening torque tends to be remarkably lower than the setting
made, or if the pulse frequency goes up - check the oil level and fill with
hydraulic oil according to the instructions.
Change the oil at the overhauls. Use hydraulic oil: 22cST/40°C (JSOVG22)

RUST PROTECTION AND INTERNAL CLEANING
Water in the compressed air, dust and wear particles cause rust and sticking
of vanes, valves etc.
This
can be solved byflushing with oil (some drops), running the machine
for 5-10 seconds
and absorbing the oil in a cloth.
Make this preparation before longer standstills.
OVERHAUL, LUBRICATION AND CHANGE OF OIL
Themachine is normallyused as a heavy-dutymachine. It should, thetefore,
be dismantled, overhauled and cleaned after 100,000 (ambitious service
level) to 250,000 (maximum) tightenings. tf it is not running properly, it
should be taken out of service for inspection.
Note: Check or change the 0-ring around the anvil's shaft. Also carefully
dean the 0-ring's groove.
The strainer at the air inlet and the exhaust silencer should be cleaned
frequently in order to prevent clogging, which decreases the capacity.
At the overhauls the throttle valve and bearings must be cleaned and
lubricated with grease. Molykote BR2 Plus gives rong intervafs between
lubrications.
If it is necessary to dismantle the vane motor, check the height and width
of
the vanes (measurements: see exploded view). The cylinder surface
must be smooth and unscored.
Note: dean the rotor and cylinder before changing vanes. Apply a thin
layer of grease, containing molybdenumdisulphide (Molykote BR2
Plus), on to the end faces of rotor or end plates. Assemble the motor
dry and check that it is running free. Add two drops of oil through
the air inlet and b.Jm the motor over so that 011 is distributed over
the intemaf motor parts.
THREADED CONNECTIONS
It is important that the machine's threaded connections are tightened
properly; i.e. in accordance with the specifications on the exploded views.
Note: Before assembly, lubricate the threads with grease.
