Foreseen Use
This screwdriver is designed for the tightening and loosening
of threaded fasteners within the range as specified by the
manufacturer. It should only be used in conjunction with
1/4" male hex shank screwdriver bits and fastener drivers.
Do not use the tool for any other purpose than that specified
without consulting the manufacturer or his authorised
representative.
Putting Into Service
Air Supply
Use a clean lubricated air supply that will give a measured
air pressure at the tool of 90 p.s.i./6.3 bar when the tool
is running with the trigger fully depressed. Use recommended
hose size and length. It is recommended that the tool is
connected to the air supply as shown in figure 1. Do not
connect the tool to the air line system without incorporating
an easy to reach and operate air shut off valve. The air
supply should be lubricated. It is strongly recommended that
an air filter, regulator, lubricator (FRL) is used as shown in
Figure 1 as this will supply clean, lubricated air at the correct
pressure to the tool. Details of such equipment can be
obtained from your supplier. If such equipment is not used
then the tool should be lubricated by shutting off the air
supply to the tool, depressurising the line by pressing the
Work Stations
The tool should only be used as a hand held, hand operated
tool. It is always recommended that the tool is used when
standing on a solid floor. It can be used in other positions,
but before any such use the operator must be in a secure
position having a firm grip and footing. The operator must
adopt a firm grip sufficient to resist the torque reaction of
the tool, i.e. the tool will try
to turn in the hand. The
operator must also be aware
that when loosening fasteners,
the tool can move quite
quickly away from the fastener
being undone. An allowance
must be made for this rear-
ward movement to avoid hand
entrapment. The operator must
also make allowance that if
the tool does turn in the hand,
the hand is not trapped
against any rigid object.

Operating
Select the correct screwdriver bit or fastener driver to suit the
screw or fastener to be tightened or loosened. Slide back the
sleeve (44) and insert appropriate drive bit. This model has
an external adjustable clutch so that the torque applied to the
fastener can be adjusted easily to give the required tightness
within the torque range of the tool. To set the tool to give a
particular torque output, turn the adjust ring (49) If the fastener
is not sufficiently tightened or cannot be loosened then the
tool in adjustable clutch mode has insufficient capacity. Select
a more powerful tool. The person setting up the tool must
be aware of this torque reaction at high setting levels of the
clutch and that the tool will try to turn against the hand. All
that is required is a firm grip. The tool, when the stall torque
position has been reached, can still be used to set or loosen
fasteners, provided the operator is aware of the need to resist
the torque reaction of the tool. The only thing that will affect
the output is a change in the air supply pressure. The output
can be increased up to the use of the maximum allowed
supply pressure and decreased with a reduction in supply
pressure until the tool fails to operate. It must also be
understood that even if the clutch is set to slip it may not do
so if the supply air pressure falls below the pressure at which
the clutch was set. It is therefore strongly recommended that
a pressure control valve is used. Information as to suitable
equipment can be obtained from your supplier. When using
the tool keep the screwdriver bit pressed firmly into the screw
head to avoid cam out and screw head damage.
Dismantling & Assembly Instruction
Disconnect tool from air supply.
Grip the tool by hand then unscrew and remove clutch
housing (7) from clamp nut (41) – left hand thread.
Remove adjust cover (47) from clutch housing (7). Pull out
the clutch assembly grip the clutch assembly and with a
sharp pointed needle tool prise out retaining ring (31) and
remove washer (46), spring (45), and ball retainer (44)
being careful not lose screwdriver bit retaining ball (35).
Again with the sharp pointed tool, remove second retaining
ring (31) and pull off spacer (43). Unscrew adjust nut (47)
and pull off washer (46), clutch spring (39) and washer
(38). Tap front end to remove 4 off balls (37). Remove
retaining ring (33) and separate clutch (36). Remove a third
retaining ring (31) and pull off drive clutch (30). Unscrew
clamp nut (41) and push out the internal assembly and
ball bearing(29), internal gear (32), 3 off planet gears (25)
and work spindle (28). Do not remove the 3 off pins from
work spindle (27). Drive out pin (6), unscrew set screw
(23) and pull off trigger (24) and remove spring (22). Grip
valve stem (21) and pull out the complete valve assembly.
Separate reverse lever (20), reverse retainer (19), o-ring
(18), reverse bushing (17) and o-ring (16). Unscrew air
inlet (2) and screw (3) and remove exhaust diffuser (4) and
damping material (5). Grip end of rotor (13) and pull out
the complete motor assembly. Remove 2 pins (11), motor
gasket (9) Grip spacer (15) and with a non metallic or soft
metal (lead of aluminium) hammer tap the splined end of
the rotor (13) to drive it through bearing (8). Remove
cylinder (12) and take out 5 off rotor blades (14) from the
rotor (12). Support end plate (10) and tap the rotor (13)
through the end plate (10) and bearing (8).
Reassembly
Clean all component parts and examine to wear before
reassembling. Look in particular for wear and cuts on o-rings,
wear on rotor blades, gear, and clutch components. Coat
all parts with pneumatic tool lubricating oil and grease all
bearings, gears, and clutch parts with a molybdenum or
lithium based general purpose grease. Before reassembling
the motor make sure that the faces of end plates (10) that
abut cylinder (12) are flat and free from burrs. If necessary,
lap on a flat very fine grade of abrasive paper. Reassemble
in the reverse order. When refitting the complete motor
assembly to housing (7) first make sure that the assembly
is clamped tightly together and the rotor spins freely, slide
the assembly with gasket into the housing (7) ensuring that
motor pin (11) locates in the motor assembly and in the
hole in the bottom of the main bore of housing (7) suited
between the two main ports. Reset the clutch as required
and/ or set the correct air pressure – see Operating.
trigger on the tool. Disconnect the air line and pour into the
intake bushing a teaspoonful (5ml) of a suitable pneumatic
motor lubricating oil preferably incorporating a rust inhibitor.
Reconnect tool to air supply and run tool slowly for a few
seconds to allow air to circulate the oil. If tool is used
frequently lubricate on daily basis and if tool starts to slow
or lose power.
It is recommended that the air pressure at the tool whilst
the tool is running is 90 p.s.i./6.3 bar. The tool can run at
lower and higher pressures with the maximum permitted
working air pressure of 100 p.s.i./7.0 bar.
