Foreseen Use of the Tool

The Spot Weld Removal Tool is designed for the purpose of removing
spot welds on automotive body panels. Do not use the tool for any
purpose other than spot drilling unless first seeking the advice of the
manufacturer or the manufacturer’s authorised representative.

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 positions but before any such use,
the operator must be in a secure position having a firm grip and
footing and be aware that the drill can develop a torque reaction.

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/lever 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 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 bar.

Operating

Insert drill item (49) as far as it will go into spindle (47) and lock in
position securely with set screws (48). The depth at which the drill
will cut can be controlled by rotating adjusting bolt (50). Connect to
suitable air supply. When drilling always try to keep the drill (49) at
right angles to the sheet on which the spot weld is to be removed.
The clamp lever (55) performs two functions i.e. a) to start the tool
by depressing throttle lever (5) and b) to move the drill (49) toward
adjusting bolt (50) and perform the drilling operation.

Dismantling & Assembly Instructions

Disconnect tool from the air supply.
Unscrew adjusting bolt (50) from clamp arm (46). Unscrew adjusting
screws (57) and take out spring (58) and remove grip handle (55).
Remove stud (53), batten (54), screw (58) and spring (58). Take out
2 set screws (44) and remove arm base (52). Unscrew set screw
(48) and pull out drill (49) from spindle (47). Unscrew air inlet bushing
(1) from valve body (10).
Take out spring (3) and spring pin (4) and remove throttle lever (5).
Unscrew throttle valve screw (16) with O-ring (15) and (14) and take
out throttle spring (13) and valve stem (14). Grip the motor body (18)
and loosen clamp nut (43). Unscrew clamp nut (43) from motor body
(18). Take out ball bearing (42) and bush (41) together with stop ring
(40) and pull out the motor assembly from motor body (18). Remove
end plate cap (19) and grip front rear plate (21) and with a non
metallic or soft metal (lead or aluminium) hammer tap the splined
end of rotor (25) to drive it through the front end plate (27) and
bearing (28). Remove cylinder (23) noting its orientation to rear end
plate (21) via pin (22) for reassembly and remove 4 off rotor blades
(24) from rotor (25). Support rear end plate (21) in a piece of tube
with a bore size as close as possible to the maximum diameter of
the rotor (25) and tap the non splined end of the rotor to drive it
through the rear end plate (21) and bearing (20). Remove spring pin
(22) from rear end plate (21). With a suitable punch tap out bearing
(28) from front end plate (27) and bearing (30) from front end plate
(27). Remove internal gear (29), 2 off idler gears (35) and work
spindle (32) with bearing (38).

Reassembly

Clean all parts and examine for wear and replace worn or damaged
parts only 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.

adjusting or removing the working attachment.

13) Check hose and fittings regularly for wear. Replace if necessary.
Do not carry the tool by its hose and ensure the hand is remote from
the on/off control when carrying the tool with the air supply
connected.

14) Take care against entanglement of moving parts of the tool with
clothing, ties, hair, cleaning rags, etc. This will cause the body to be
drawn towards the tool and can be very dangerous.

15) It is expected that users will adopt safe working practices and
observe all relevant legal requirements when installing, using or
maintaining the tool.

16) Do not install the tool unless an easily accessible and easily
operable on/off valve is incorporated in the air supply.

17) Take care that the tool exhaust air does not cause a problem or
blows on another person.

18) Never lay a tool down unless the working attachment has
stopped moving.

19) Always check the speed of the attachment is higher than the
speed of the tool.

20) Check speed of tool at regular intervals.

Safety Rules For A Spot Weld Remover

1) Read all the instructions before using this tool. All operators must
be fully trained in its use and aware of these safety rules.

2) Do not exceed the maximum working air pressure.

3) Use personal safety equipment.

4) Use only compressed air at the recommended conditions.

5) If the tool appears to malfunction remove from use immediately
and arrange for service and repair.

6) If the tool is used with a balancer or other support device ensure
that it is fixed securely.

7) Always keep hands away from the working attachment fitted to
the tool.

8) The tool is not electrically insulated. Never use the tool if there is
any chance of it coming into contact with live electricity.

9) Always when using the tool adopt a firm footing and/or position
and grip the tool firmly to be able to counteract any forces or reaction
forces that may be generated whilst using the tool.

10) Use only correct spare parts. Do not improvise or make
temporary repairs.

11) Do not lock, tape, wire, etc. the on/off valve in the run position.
The trigger/lever etc. must always be free to return to the 'off'
position when it is released.

12) Always shut off the air supply to the tool, and depress the
trigger/lever etc. to exhaust air from the feed hose before fitting,
