Desoutter Limited
Eaton Road Hemel Hempstead Hertfordshire HP2 ?DR 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 long hair away 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.
10. Must not be used in explosive atmospheres.
11. Power tools are 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 INJURY.
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 life, and performance may be enhanced when
a lubricated air line is used.

WEIGHT
0.95 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 machine life we recom mend
use of compressed air with a dew point between +2°C and + 10°C.
- Use a separate air filter installed as close 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 quantity of oil (1-5 mg/m3). Air quality
according to ISO/TC 118, quality class 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
SETTING 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 turns 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.
Before adjusting, dismount the 0-ring and remove the sleeve and unscrew
the housinq. Remove the pulse unit.
After adjusting, place the pulse unit in the housing and attach it to the
motor unit. Do not forget to assemble the sleeve and the 0-ring.
CHECKING THE OIL IN THE PULSE-UNIT
The oil level shall be checked after every 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 (ISOVG22)

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 by flushing with oil (some drops), running the machine
for 5-1
O
seconds and absorbing the oil in a cloth.·
Make this preparation before longer
standstill~.
I
OVERHAUL, LUBRICATION AND CHANGE OF OIL
The machine is normally used as a heavy-duty machine. It should, therefore,
be dismantled, overhauled and cleaned after
100~000
(ambitious service
level) to 250,000 (maximum) tightenings. If 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
clean 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
d~reases
the capacity.
At the overhauls the throttle valve and
bearing~
must be cleaned and
lubricated with grease. Molykote BR2 Plus gives jong intervals between
lubrications.
If it is necessary to dismantle the vane motor,
che~k
the height and width
of the vanes (measurements: see exploded
vie~).
The cylinder surface
must be smooth and unscored.
Note: Clean the rotor and cylinder before changing vanes. Apply a thin
layer of grease, containing
molybdenumdi~ulphide
(Molykote BR2
Plus), on to the end faces of rotor or end
pla~es.
Assemble the motor
dry and check that it is running free. Add t.;vo drops of oil through
the air inlet and turn the motor over so that oil is distributed over
the internal motor parts.
THREADED CONNECTIONS
It is important that the machine's threaded conrections are tightened
properly; i.e. in accordance with the specifications!on the exploded views.
Note: Before assembly, lubricate the threads with1grease.
