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 without
consulting the manufacturer or the manufacturer's authorised supplier.
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
trigger on the tool. Disconnect the air line and pour into the intake
bushing a teaspoonful (5ml) of a suitable pneumatic motor lubricating
Work Stations
The tool should only be used as a handheld hand operated tool. It is
always recommended that the tool is used when standing on the solid
floor. It can be
used in other posi-
tions 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 de-
velop a torque re-
action see section

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 counteract any
sudden movement 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 tough. The torque reaction
can occur when the drill breaks through the material being drilled,
particularly on sheet metal. Always use eye protection and hand
protection is advised, particularly when drilling holes in metals where
the material being removed from the hole is in the form of long sharp
strips. Do not tie the drill chuck key to the drill as the attaching device
i.e. string or chain could become entangled with the rotating chuck
and bit etc.
If using an abrasive device, drilling stone or performing any 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 tool from the air supply.
Open the jaws of drill chuck (2) and remove screw (1). Hold motor
housing (17) in a vice fitted with soft jaws and fix the chuck key firmly
in the drill chuck (2) and give the chuck key a sharp tap with a
hammer in the direction to loosen a right hand threaded joint. If this
fails to remove the chuck as it is too tightly fitted see later:-
Unscrew gear housing (3) and remove the gearbox assembly
complete. Take out internal gear (8) and 3 off planet gears (7). If the
drill chuck has not previously been removed then wedge a
rectangular bar between the three pins in planet carrier (6) and then
by use of the chuck key unscrew drill chuck (2). Support the end of
gear housing (3) and carefully, so as not to damage the thread, tap
planet carrier (6) together with 2 off bearings (5) out of the gear
housing. Support the motor side of the outer rings of bearings (5) and
press planet carrier (6) through them. Grip the end of rotor (12) and
pull out the complete motor assembly from the motor housing (17).
Note at this time, for reassembly, how motor pin (14) locates the
motor assembly by locating in the rectangular slot in the bottom of the
main bore of the motor housing (17). Remove motor pin (14). Hold
bearing case (10) tightly by hand and tap the splined end of rotor (12)
with a non metallic [lead or aluminium] hammer so as not to damage
the splines and drive the rotor through the bearing case (10)
assembly. Tap out bearing (9) from bearing case (10).
Remove cylinder (15) and 4 off rotor blades (13). Support rotor (12)
in a piece of tube with a bore diameter as close as possible to the
maximum diameter of the rotor and tap the non splined end of the
rotor to drive it through end plate (11) assembly. Tap out bearing (9)
from rear plate (11).
Unscrew air inlet with air filter screen (31), remove 2 off screws (30)
and take off exhaust deflector (29). Prise off trigger (20) and remove
spring (21). Centralise the forward and reverse lever (24) so that it
aligns with the slot and pull out the valve assembly complete.
Separate the parts, i.e. reverse valve (24), O-ring (25), reverse valve
bush (26), throttle valve (22) and O-rings (23),(23a) and (27).
Reassembly
Clean all parts and examine for wear and replace any parts with parts
obtained from the manufacturer or an authorised distributor. Coat all
parts with a suitable pneumatic tool lubricating oil and reassemble in
the reverse direction. See Note.
Note:- Before reassembling the motor assembly make sure that the
faces of bearing case (10) and rear plate (11) that abut cylinder (15)
are flat and free from burrs. If necessary lap on a flat very fine grade
of abrasive paper.
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.

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 carrying the tool with air supply 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.
12) Use only compressed air at recommended conditions.
13) Do not attempt to fit attachments, i.e. for sawing, hedge cutting,
grinding, chain sawing, etc.
14) If the tool appears to malfunction remove from use immediately
and arrange for service and repair.
15) If an additional side handle is fitted to the tool ensure that it is
correctly positioned and fixed securely.
16) If the drill is used with a balancer or other suspension device
ensure that it is fixed securely.
