Foreseen Use Of The Tool

The tool is designed to be used only for the purpose of driving,
tightening and loosening of threaded fasteners, usually nuts and bolts,
when fitted with a suitable drive socket.
It is allowed to use suitable extension bars, universal joints and socket
adaptors between the square output drive of the ratchet wrench and
the female square drive of the socket.
Do not use the tool for any other purpose than that specified without
consulting the manufacturer or the manufacturer's authorised supplier.
To do so may be dangerous.
Never use the ratchet wrench as a hammer to dislodge or straighten
cross threaded fasteners. Never attempt to modify the tool for other
uses and never modify the tool even to be used as a ratchet wrench.

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 when loosening fasteners the tool
can move quite quickly away from the fastener
being undone. An allowance must always be
made for this rearward movement so as to
avoid the possibility of hand/arm/body en­trapment.

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 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.

Page No 1

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

Fit securely to the tool the socket or attachment required to perform the
operation. Ensure that the reverse button situated on the opposite side
to the square drive output shaft is in the correct position for tightening or
loosening the fastener.
The nut/bolt can then be run down the thread using the power drive of
the tool. When the tool stops the handle of the tool can be used as a
ratchet lever and operated to give the required tightness of the joint.
For loosening a joint the tool can be used in the reverse sequence.

Tool Maintenance

It shall be the tool owner’s and/or employer’s responsibility to assure
that tools are maintained in a safe operating condition. Tool
maintenance and repair shall be performed by authorised, trained,
competent personnel. Tools shall be disconnected from their
compressed air supply before repairs are attempted. Repairs shall be
consistent with the manufacturer’s recommended procedures. Tool,
hoses and fittings shall be replaced if unsuitable for safe operation. It
shall be the tool owner’s and/or employer’s responsibility to keep
required rating markings and warnings on the tool in legible condition.

Safety Rules For A Ratchet Wrench

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,
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 ensure that the reverse button is in the selected position
before starting the tool.

20) Do not use sockets with excessive wear to the input and output
drives. Periodically check the square drive on the ratchet wrench. Make
sure the socket, extension is firmly fixed to the tool.

21) When loosening fasteners first ensure that there is sufficient
clearance behind the tool to avoid hand entrapment. The tool will move
away from the threaded joint as the nut/bolt is loosened and rides up
the thread moving the tool with it.
