Foreseen Use Of Tool
This drill is designed for the purpose of drilling holes in all types
of materials, i.e. metals, wood, stone, plastics etc. using drilling
bits designed for this purpose. It may be used with other forms
of cutting tools, polishing devices or for sanding using coated
abrasive products. Before using any such products first check
with the manufacturer their suitability for use with this type of
drill. Do not use bonded abrasive products (i.e. grinding wheels)
or saw blades or any device which has a permitted safe working
speed less than the free speed of the drill.
Do not use this drill for any other purpose than that specified
with out co nsul ti ng th e ma nufa ctur er or th e man uf act urer 's
authorised supplier.
Work Stations
The tool should on ly be
used as a handheld hand
operated tool. It is always
recommended that the
tool is used when stand-
ing on the solid floor. It
can be used in other po-
sitions but before any
such use, the operator
must be in a secure posi-
tion having a firm grip
and footing and be aware
that the drill can develop
a torque reaction see
section "Operating".

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 sys tem withou t incorporating an easy to reach a nd
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 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 sec onds 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.
Operating
Select suitable drill bit, insert the shank into the drill chuck as far
as possible and tighten chuck with key supplied making sure
that the shank of the device is securely clamped centrally
between the three chuck jaws. Remove chuck key.
When drilling holes of all sizes it is advised to use a pointed
punch to mark the centre at which the hole is to be drilled as
this will provide a starting point for the drill tip. This procedure
will prevent the drill bit from skidding, ensure that the hole is
drilled where intended and help to prevent drill breakage when
using small drills. When drilling, particularly with small diameter
drills, always try to ensure that load applied to the drill is such
that the drill bit is always at right angles to the hole being drilled.
Do not force the drill but allow it to cut.
When drilling always adopt a firm posture to be able to
counte ract an y sudden moveme nt of the drill due to torque
reaction. Such torque reaction can occur when the drill stalls
due to a too heavy load being applied or the material being too
hard or tou gh. The torque reaction c an occur w hen the drill
breaks through the material being drilled, particularly on sheet
metal . A lw ays us e eye p r ot ecti o n and hand p ro tec ti o n is
advised, particularly w hen drilling h oles in me tals whe re the
materia l being remove d from the hole is in the form of long
sharp strips. Do not tie the drill chuck key to the drill as the
attach ing device i.e. string or chain could become entangled
with the rotating chuck and bit etc.
If using a n abrasive device, drilling stone or performing a ny
operation where dust is created, it is recommended to use a
breathing mask.
Always ensure that the material to be drilled is firmly fixed to
prevent its movement.
It is also recommended that when drilling holes of large
diameter to first pre drill a hole of smaller diameter as this will
reduce effort required to drill the hole and minimise torque
reaction.
Dismantling & Assembly Instructions
Disconnect from air supply
To remove the chuck (59) first open the chuck jaws with the key
provided and remove chuck screw (55) left hand thread. Place
chuck key securely into chuck and give the key a sharp tap so
as to unscrew a right hand thread. Grip motor housing (1) in a
vice with soft jaws on the flats at the rear end. Drive out pin (10)
and take off the throttle lever (9) Unscrew inlet bushing (3) With
a needle pointed tool, prise out deflector retainer (6) pull out

Reassembly
Clean all co mp onent part s and e xamin e for wear b efo re
reass em bling. Use on ly m an u fac tu rer or distributor su pplied
parts.
Check in particular for wear on bevel gears, o-rings and rotor
blades.
Lightly coat all parts with a suitable pneumatic tool lubricating
oil, preferably one incorporating a rust inhibitor. Pack bearings
and grease gears and bevel gears with a lithium or molybdenum
based general purpose grease. Reassemble in the reverse order
taking note of the following:
1) When fitting gasket (27) make sure that it does not cover
the ports and is positioned correctly.
2) Make sure that the motor locating pin locates correctly in
the holes in the motor end plates and in the small hole
between the two ports at the bottom of the bore of the
motor housing
3) For the motor assembly, ensure that the motor end plates
that abut the cylinder are flat and are free from burrs and
sharp edges. If necessary lap the faces on a fine grade of
abrasive paper laid on a flat surface.
Safety Rules When Using A Drill
1) Read all the instructions before using this tool. All operators
must be fully trained in its use and aware of these safety rules.
All service and repair must be carried out by trained personnel.
2) Always select a suitable cutting, abrasive device suitable for
use with this drill.
3) Always shut off the air supply to the drill and depress the
trigger to exhaust air from the feed hose before fitting, adjusting
or removing the device. Remove drill chuck.
4) Always adopt a firm footing and/or position and be aware of
torque reaction developed by the drill.
5) Use only correct spare parts.
6) Check hose and fittings regularly for wear. Do not carry the
tool by its hose and ensure that the hand is remote from the
on/off valve (trigger) when ca rrying the tool with air s upply
connected.
7) Do not exceed maximum recommended air pressure. Avoid
low air pressures as this will allow the drill to stall more easily
and develop torque reaction.
8) Use safety equipment as recommended.
9) The tool is not electrically insulated. Do not use where there
is a possibility of coming into contact with live electricity, gas
pipes, water pipes, etc. Check the area of operation before
performing the operation.
10) Take care against entanglement of moving parts of the tool
with clothing, ties, hair, cleaning rags, etc. This will cause the
body to be moved towards the work process and can be very
dangerous.
11) Do not attempt to hold or guide the drill chuck when the tool
is running. Keep hands clear of the drilling process.
