'On/Off' valve to exhaust the air from the feed hose
before fitting,
removing or adjusting
the working
attachment fitted to the tool.
- Before using the tool, make sure that a shut off device
has been fitted to the air supply line and the position is
known and easily accessible so that the air supply to
the tool can be shut off in an emergency.
- Check hose and fittings regularly for wear.
- Take care against entanglement of the moving parts of
the tool with clothing, hair, ties, cleaning rags, rings,
jewelry, watches, bracelets, etc. This could cause the
body or parts of the body to be drawn towards and in
contact with the moving parts of the tool and could be
very
dangerous.
- It is expected that users will adopt safe working
practices and observe all local, regional and country
legal
requirements
when
installing,
using
or
maintaining the tool.
- Take care that the exhaust air does not point towards
any other person or material or substance that could
be contaminated by oil
droplets.
When first lubricating
a tool or if the tool exhaust has a high oil content, do
not allow the exhaust air to come near very hot
surfaces or
flames.
- Never lay the tool down until the working attachment
has stopped moving.
- When the tool is not in use, shut off the air supply and
press the trigger/lever to drain the supply line. If the
tool is not to be used for a period of time, first lubricate,
disconnect from air supply and store in a dry average
room temperature environment.
- If the tool is passed from one user to a new or
inexperienced user, make sure these instructions are
passed with the tool.
- Do not remove any manufacturer fitted safety devices
where fitted,
i.e.,
wheel guards, safety trigger, speed
governors, etc.
- Wherever possible, secure workpiece with clamps, a
vise, etc. to make it rigid so it does not move during the
work
operation.
Keep good balance at all times. Do not
stretch or overreach.
- Try to match the tool to the work operation. Do not use
a tool that is too light or heavy for the work operation. If
in doubt, seek advice.
-In
general
terms,
this tool is not suitable
for
underwater use or use in explosive environments -
seek advice from manufacturer.
- Try to make sure that the work area is clear to enable
the work task to be performed safely. If practical and
possible, try to clear unnecessary obstructions before
starting
work.
- Always use air hose and couplings with minimum
working pressure ratings at least 1 1/2 times the
maximum working pressure rating of the tool.
Foreseen Use Of The Tool- 5011/5013
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
authorized 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 01 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.l6.2 bar when the tool is running
with the triggerllever 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
oil valve. The air supply should be lubricated. It is strongly
recommended that an air filter, regulator, lubricator (FRLl is used
as
shown
In Flgure1 as
thIs
will supply
cllian,
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. depressurizing the line by pressing the triggerllever on the
tool. Disconnect the air line and pour into the hose adaptor 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. \I 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 while the tool is
running is 90 psU6.2 bar.
Operating
Fit securely to the tool the socket or attachment required to
perform the operation. For safe operation use
only
impact or
power
type
sockets.
Ensure that the reverse lever
(6)
situated
on the
opposite side to the square drive is in the correct position to give the
direction of rotation
required.
Turning it counter clockwise makes the
ratchet turn clockwise and vice-versa. The lever (42) depresses
a valve (38) which controls the lIow of compressed air to the motor
assembly.This feature can be used by varying the depression
ot
the
lever (42) to vary the speed and output of the tool. Always use the
correct size socket to match the fastener being tightened or
loosened. Do not use worn or damaged sockets. \I the tool is used
daily, then the ratchet mechanism should be greased once per week.
Adjust lubrication schedule according to
usage.
The nutlbolVfastener can be run down the thread using the power
drive of the tool. When the tool
stops, i.e.
the motor
stalls,
the handle
can be used as a ratchet lever and operated to give the required
tightness of the joint. For loosening a joint, the tool canbe,!Ili&'ijn
the reverse sequence. The air pressure sUPPlied to the tool can be
varied to change the output torque of the tool. The higher
the
pressure the higher the torque output. Be careful not to over tighten
fasteners.
At 90 PSIG the ratchet wrench
releases
about 50 Ib.tt.
(68 Nm).
Air Strainer
An air strainer is located in the air inlet (41) of the ratchet wrench.
The internal strainer may become blocked during use reducing the
performance of the tool. The hose adaptor may be removed so that
the strainer may be
cleaned.
Dismantling & Assembly Instructions
Disconnect tool from air supply.
Remove boot (1) then grip motor housing (34) with cover (43) on its
lIats in a vise fitted with soft jaws and unscrew inlet bushing with
screen (41). Tap out throttle lever pin (40) to remove lever
(42)
and pull off housing cover (43) from motor housing (34). Remove
retaining ring (15) and by moving yoke (2) from side to side, push out
the front end drive assembly. Remove thrust washer (14) and 2 steel
balls (13) and 2 springs (12) from ratchet anvil assembly. Push out
