of health surveillance to detect early symptoms which mayrelate
to vibration exposure, so that management procedures can be
modified to help prevent future impairment.

Principle
Inside CP7600, a valve unit combines 2 key functions:
driving the air through the two pneumatic motors and
shutting off the air supply of the tool. Installation
Rundown
Rundown motor Tightening motor Air quality
–For optimum performance and maximum machine life we re-
commend use of compressed air with a dew point between
+2°C and +10°C. Installation of a refrigeration-type air dryer
is recommended.
–Use a separate air filter to remove solid particles larger than
30 microns and more than 90 % of water, installed as close as
possible to the machine and prior to any other air preparation
unit. Blow out the hose before connecting.
–The compressed air must contain a small quantity of oil. We
strongly recommend that you install a oil-fog lubricator to be
set normally at 3-4 drops(50mm3)/m3air consumption for long
cycle running tools, or a single-point lubricator for short cycle
running tools.
–Regarding lubrication free tools it is, at the customers option,
nodisadvantageif thecompressedaircontainsasmallquantity
of oil as supplied from a lubricator.An exception is turbine
toolsthatshouldbekeptoilfree.(Forfurtherinformationplease
see Air Line Accessories in our main catalogue.)
Compressed air connection
–The machine is designed for a working pressure (e) of 3–7 bar
= 300–700 kPa = 44-102 psi.
–Blow out the hose before connecting.
When pulling the trigger, the air flows through the valve unit,
driving the air through the rundown motor that rotates. This motor
drives a low ratio gear generating high speed and low torque.
Motor switch
As the torque load applied on the CP7600 output drive increases,
the rundown motor slows down, leading to a higher air pressure
inside the motor. Under this higher pressure, the valve is pushed
to another position.
Tightening
The air is then driven through the tightening motor. This motor
drives a high ratio gear generating low speed and high torque.
Shut off
As the torque load continues to increase, the tightening motor
slows down, leading to a higher air pressure in the motor. When
this air pressure exceeds the adjusted pressure of a spring, a piston
in the valve unit is pushed, shutting off the whole air admission.
Adjusting the shut off
The spring pressure is adjusted when calibrating of the tool. A
specific air pressure (usually 6.3 bar/90 psi) leads to a specific
torque.
Recommended installation
Toensurecorrectcapacityofthe machine,westronglyrecommend
you to follow the enclosed installation proposal from the air net-
work tapping point to the tool.
Handling
Tightening torque setup
For accurate operation and safety, the tightening torque of the nut
runner must be set correctly in relation to the screw joint. Check
the tightening torque given to the joint in question.
The air pressure supplied by the FRL unit is set according to
the pressure written on the calibration certificate at free speed
(trigger fully pressed and nutrunner running freely with no load
during a couple of seconds) usually 6.0 - 6.3 bar = 87 - 91 psi.

A change in the air pressure will affect the behavior
of the shut off.
If the air pressure is higher than the calibration air
pressure, the shut off will operate earlier and the
torque will be lower than expected.

Single torque selector
Adjust the torque setting by means of the adjustment key. The
torque is increased when screwing the screw counter clockwise.
After adjustment, check the tightening torque given to the joint in
question.
A If shut-off is carried out at high speed of revolution, causing a
high torque scatter, it is recommended to reduce the air pres-
sure.
4-position selector
In order to set Torque 1, turn the rotary switch to the ref. mark on
the housing. Set the adjustment screw 1. See mark on the switch
how to increase/decrease the torque. Toset Torque 2, turn the
rotary switch to the Ref. 2 mark onthe housing. Setthe adjustment
screw 2.
Remember your torque settings by placing your own markings on
the four areas on the housing.
Operating instructions
Tightening torque selection
Push the black button. Turn the rotary switch to desired position.

2: Turn to the right
The red arrows indicate the direction of running. I.e. the machine
will run counter–clockwise when started.
When changing back to the clockwise position, pull the ring
back –left –back, see Fig. below.

Check that the spring loaded tube is firmly fitted along the reac-
tion arm.
Apply the reaction bar in the wanted position before starting
the machine.
Reaction arm must absolutely turn around hub.

c: No arrows visible
Instructions for reversing
As there is no automatic return of the gear shift to a fixed position,
always check before starting that gear shift is in clockwise position
or counter-clockwise position with all arrows clearly visible.
Maintenance
For maximum performance
It is important to lubricate regularly to get maximum performance
and trouble-free operation. The motor should be lubricated with
oil; i.e. drops of oil can be dropped either into the compressed air
or directly into the air inlet.
The trigger, planetary gears, needle bearings and ball bearings
should be lubricated with grease during the regular overhaul of
the machine.

The angle gear and clutch must be lubricated using grease that
contains molybdenum disulphide: Molykote BR2 Plus, for ex-
ample, or an equivalent brand.
Use lubricants of good quality. The oils and greases mentioned
in the table are examples of lubricants which are recommended.
Grease guide Nutrunners
Rust protection and internal cleaning
Water in the compressed air, dust and wear particles cause rust
and sticking of vanes, valves etc. An air filter should be installed
close to the machine (see “Air quality”).
Service instructions
Overhaul and preventive maintenance is recommended at regular
intervals once per year or after maximum 250.000 tightening de-
pending on which occurs sooner. More frequent overhaul may be
needed, if used at high torque and long tightening times. If the
machine not is working properly, it should immediately be taken
away for inspection.
The strainer at the air inlet and the exhaust silencer should be
cleaned frequently or replaced in order to prevent clogging, which
decreases the capacity.
At the overhauls, all parts should be cleaned accurately and de-
fective or worn parts (i.e. O-rings, vanes) should be replaced.
