INTRODUCTION
The BC-RAD-X Battery Torque Wrench is a handheld, battery driven reversible non-impacting torque
delivery power tool intended to tighten and un-tighten nuts, bolts and threaded fasteners.
The BC-RAD-X Electrical torque wrench must always be used with the following:-
Battery Pack Supplied
Impact Quality Sockets
Ring and pin fastener system (or similar)
Reaction Arm
240V or 110V electrical battery charger (dependant on model purchased)
If the intended use is other than for nuts, bolts and threaded fasteners contact W. Christie (Industrial) LTD
for guidance.
It is the responsibility of the user to consider associated site risks before introducing the equipment into
the work-place.

TRAINING REQUIREMENTS
Training on the correct use of the BC-RAD-X Battery Torque Wrench is available. Please contact
W. Christie (Industrial) LTD for more information.
GENERAL SAFETY
The improper use of the BC-RAD-X Battery Torque Wrench is unsafe and may result in personal injury.
It is important that operators have read, understood and comply with all instructions in this user guide.
Operators must be equipped with the following personal protective equipment (PPE):
Eye Protection (Safety Glasses / Goggles)
Safety Footwear (Steel Toe Cap Boots)
Heavy Gloves
Impact quality sockets must be secured to the tool square drive by means of a ring and pin combination.
Only use BC-RAD-X Wrenches with impact quality sockets. Do not use with extension bars or universal
joints.
Do not use in the presence of explosive gases or liquids - fire/explosion hazard
Only use BC-RAD-X wrench battery charger with 240v or 110v electrical power supply (dependant on
model purchased)
To prevent entanglement with rotating parts operators must not wear loose clothing, ties, jewellery etc…
Long hair must be tied back.
Always keep hands, fingers and body parts clear of the reaction arm at all times. Trapping in this area can
result in serious personal injury.
All equipment and ancillary products should be inspected for damage and irregularities prior to use. If in
doubt do not use.
IMPORTANT:- BC-RAD-X WRENCHES RELY ON AN INTERNAL CLUTCH TO
REGULATE TORQUE OUTPUT. AS THE CLUTCH WEARS, TORQUE
OUTPUT MAY VARY. IT IS STRONGLY ADVISED THAT WHEN USING
BC-RAD-X WRENCHES FOR ANY BOLTING WORK, TOOLING IS
CHECKED FOR TORQUE ACCURACY ON SUITABLE TEST EQUIPMENT
PRIOR TO USE. FOR APPLICATIONS OF A CRITICAL NATURE, BC-RAD-
X WRENCHES MUST BE TORQUE CHECKED DAILY.
W. CHRISTIE (INDUSTRIAL) LTD OFFER A TORQUE CHECKING
SYSTEM (RUN DOWN FIXTURE) FOR SALE OR HIRE TO MONITOR THE
TORQUE OUTPUT OF ALL TORQUE TOOLS BETWEEN ANNUAL
CALIBRATION DATES.

BATTERY PACK SAFETY
Do not attempt to charge a fully charged battery pack. Disconnect immediately if there is any sign of
smoke or flames.
Keep battery packs dry at all times.
Do not store in direct sunlight.
Do not expose to fire or immerse in water.
Do not attempt to open or break into the battery pack.
Do not touch contacts or terminals or attempt to short circuit them.
Do not dispose of battery pack with domestic waste.
CAUTION: If battery fluid leaks out and comes into contact with skin, rinse immediately with cold
water.
If battery fluid comes into contact with eyes, wash them immediately with clean water and
seek immediate medical advice.

TORQUE REACTION
When the Christie BC-RAD-X wrench is in operation the reaction arm rotates in the opposite direction to
the output square drive and must be allowed to rest squarely against a solid object or surface adjacent to
the bolt to be tightened. (See Figure Below).
Ensure the Reaction Arm is NOT resting on a sloping or bevelled face.
SPECIAL NOTICE: TIGHT FASTENERS
When tightening or releasing tight fasteners, the torque required to move the nut may be high enough to
keep the reaction locked in one position. This can cause the reaction plate to bend or cause gearbox
failure. To prevent failure, re-position the reaction plate after every two turns of the fastener, i.e operate
the tool briefly in the opposite direction.
TRAPPING HAZARD:-
Always keep hands, fingers and body parts clear of the reaction arm when the tool is in use or
trapping injury will result

SAFE REACTION ZONE
Care must be taken to ensure that the reaction arm is only used within the limitations shown in the figure
below. Failure to observe this instruction will result in premature wear or damage to the wrench. Do not
react on the reaction arm vertical crank or inside edge. Extreme forces are created which may cause
damage to the wrench. If the application does not allow the use of a standard reaction arm, non-standard
reaction arms are available.
Customers must not modify reaction arms and are strongly advised to contact W. Christie (Industrial)
LTD technical assistance.

SETTING TORQUE FOR BOLT TIGHTENING
1) Ensure The battery pack and reserve battery are fully charged (see “Battery
Charging” section)
2) Set the Direction Selector Switch (D) to forward.
3) Identify the torque required for the bolting application.
-The BC-RAD Wrench comes with a torque calibration certificate. This
document displays the settings that are selected using the Torque Setting
Dial (E) and viewed on the Selection Scale (K)
-For example on the “Sample BC-RAD-X Calibration Certificate shown right, to tighten to 316Nm
move the Torque Setting Dial (E) until the number 4 is lined up on the Selection Scale (K)
CAUTION: Do Not Attempt to run the tool with settings that are not displayed on the torque calibration
certificate. Failure to do so could cause the tool to fail and void your warranty
SETTING TORQUE FOR BOLT LOOSENING
1) Set the Direction Selector Switch (D) to reverse.
2) Set the torque to maximum.
-For example on the “Sample BC-RAD-X Calibration Certificate shown top right, to tighten to
maximum torque dial the Torque Setting Dial (E) until the number 7 is lined up on the
Selection Scale (K)

OPERATING THE WRENCH
1) Fit the wrench with the correct size impact socket to suit the bolt to be tightened and retain with ring
and pin system
2) Rotate the handle to convenient position relative to the reaction arm.
3) Fit the tool onto the bolt to be tightened / un-tightened with the reaction arm adjacent to the reaction
point (See “Torque Reaction” Section)
4) Move the Direction Selector Switch (D) from the neutral position and into either forward or reverse
as required.
5) Squeeze the Trigger (C) to bring the reaction arm into contact with the reaction point.
6) Fully press the Trigger (C) and keep pressed until the clutch slips producing a pronounced ratcheting
sound. When this happens release the Trigger (C) Immediately. If the trigger is released before the
wrench clutch slips, full torque will not be applied to the bolt. Once the clutch slips do not “blip” the
trigger, or incorrect torque will be applied. Damage to tooling will result if the clutch is allowed to
slip for extended periods of time.
7) In use this tool must be supported at all times in order to prevent unexpected release of a fastener or
component failure.
8) If during the un-tightening process the fastener does not release, and the clutch slips continuously, a
tool of greater torque capacity must be used. Damage to tooling will result if the clutch is allowed to
slip for extended periods of time.
9) If during tightening or un-tightening the tool stops rotating, but no ratcheting sound is heard from the
clutch, the torque has Not been achieved. Release the trigger and replace or recharge the battery and
re-tighten the fastener(s).
10)Remove tool from bolt.
IMPORTANT: For applications of a critical nature, BC-RAD-X wrenches must be torque checked
daily.
If breakdown, malfunction or damage occurs do not attempt to repair, contact w.
Christie (Industrial) LTD immediately on [phone]
MAINTENANCE AND RECALIBRATION
To prevent premature failure and ensure confidence in torque supply, it is recommended that this
equipment is serviced and calibrated at least on an annual basis, by W. Christie (Industrial) LTD.
There are no user serviceable parts. If any failures, breakdown, malfunction or damage occurs do not
attempt to repair, contact W. Christie (Industrial) LTD immediately on [phone]
W. Christie (Industrial) LTD Offer a torque checking system (run down fixture) for sale or hire to
monitor the torque output of all torque tools between annual calibration dates.
