STEP ONETurn handle to minimum torque

position and lock the handle

STEP FIVESlide the new handle on to the wrench. Be sure to align the handle with the “0”

sightly to the left of the scale center line. Using the torque wrench set to 15 Ft. Lb. and the 5/16 hex bit socket, torque lock

plug to 15 Ft. Lb. Check calibration and if necessary recalibrate wrench. Please note

that the new load point for both usage and calibration is here.

Calibration ProcessUse a mechanical loader with a tester possessing an accuracy of at least +/-1%. A more accurate tester is always preferable.

Procedure1. Determine current performance to standard.

• Test wrench on torque analyzer/tester.

– Cycle wrench at 100% of capacity a minimum of three times.

– Set wrench to 20% of capacity, cycle three (3) times and record readings.

– Set wrench to 60% of capacity, cycle three (3) times and record readings.

– Set wrench to 100% of capacity, cycle three (3) times and record readings.

• Compare readings to tolerance for each torque level.

– If wrench is within tolerance, it may be returned to service.

– If wrench is out-of-tolerance, go to next step.

2. Calibrate wrench.

a. Remove tang access screw.

b. Remove griplock control knob and hex stem lock.

c. Rotate aluminum grip to 100% of capacity (highest graduation + 0 on increment).

d. Place wrench on torque analyzer/ tester, click several times, note values obtained.

e. Adjust wrench.

– If readings are above tolerance, turn tang adjustment screw slightly CW, then repeat step 2d.

– On the models highlighted on the last page there is a second set screw that is used as a jam nut. That (jam nut) set screw needs to be removed in order to make the calibration adjustment.

– If readings are below tolerance, turn tang adjustment screw slightly CCW, then repeat step 2d.*

– If readings are in tolerance, go to next step.

f. Rotate grip and adjust torque to 20% of capacity (lowest graduation + 0 on increment).

g. Place wrench on torque analyzer/ tester, click several times, note values obtained.

– If out-of-tolerance, go to next step.

– If in tolerance, check at 60% and 100% of capacity.

h. Rotate grip CW or CCW enough clicks to bring into tolerance at 20% of scale.

i. Lock load screw by rotating internal 5/32” internal hex screw in the CCW direction.

j. Use 5/16” hex key to remove lock plug by rotating in the CCW direction.

k. Rotate grip until it aligns with lowest graduation + 0 increment (20% of capacity).

l. Replace lock plug using torque wrench, torque lock plug to 15 Ft. Lb.

m. Return to step 2c.

n. Replace hex stem, lock control knob and lock control knob set screws. Tighten to 12.5 In. Lb.

o. If necessary, tighten setscrew in lock control knob until it lightly touches bottom, then back off 1/4 to 1/3 turn.

p. Replace tang access screw and grip.

*This adjustment should only be made at 100% capacity and it effects the calibration on a percentage basis meaning a change of 4% at the high end of the scale will effect the lower end of the scale by 4%. Example on a 200 Nm wrench a change of 4% = 8 Nm however at the bottom of the scale 40 Nm it would equal 1.6Nm or 4%.

STEP FOURUsing 5/16 hex bit socket to remove

lock plug. Pull the handle straight back and remove from wrench.

STEP SIXSelect the correct hex stem lock from the conversion chart* for the model you are

converting. Hold wrench in a vertical position as shown. Insert the hex stem lock into the hex opening in the lock control knob. Gently rotate knob with

inserted hex key to complete engagement with locking screw inside of the load screw

assembly. NOTE: It is important that you DO NOT unlock the handle during

this process.

STEP THREEUsing an internal straight tips retainer

ring pliers, (3/8”–1” or 10–25 mm) squeeze and remove the snap ring, griplock

and hex stem lock.

STEP EIGHTApply “Locktite® 222” threadlocker

to the 5/16”–18 x 5/16” set screw thread. Tighten set screw into the lock knob using 5/32 hex key so it contacts, or

stops with the top face of the hex key, then rotate it back 1/4–1/3 of one turn.

Let the Locktite® dry for 12 hours.

STEP TWOLoosen the set screw using the 3/32 hex key in the back of the griplock

eight turns. To release tension gently tap griplock.

STEP SEVENTorque griplock set screws using 7/64 hex

key to 12.5 In. Lb. or until snug. To test lock after full assembly: Place in vertical

position with handle facing upwards. If the set screw is sticking out of the lock knob,

or the hex is too short, replace the hex stem lock with the other supplied hex

stem lock in the grip kit.

Tips1. Be sure to exercise the wrench at

least three (3) times prior to testing at both the low and high end of the scale.

2. Align the load point and the center ofthe pillar on the tester.

3. Keep the speed of testing consistent.

4. Be sure to return the tester to theneutral position so the wrench iscompletely released.

5. After testing the wrench on themechanical loader use the sametransducer and test by hand. Yourreadings should be very close.

6. When calibrating the high end ofthe wrench scale, set the wrenchslightly over capacity. The wrenchwill slightly settle down to thedesired capacity. If the wrench has a150 Ft. Lb. capacity calibrate thehigh end for 152 Ft. Lb.

7. Always have the lock knob tightenedor locked for testing. Turn CCW to lock.
