SPLIT BEAM
TORQUE WRENCH
TRQ62103 - 3/8 in. Drive Split Beam Torque Wrench (20–100 .-lb.)

Product Manual
Before using the torque wrench, be sure to read and understand the entire manual.
This tool is a precision measuring instrument that should be operated, stored, and
maintained with care. Failure to follow instructions could result in damage to the
tool, damage to property, or injury.

Flip the cover down to
access the adjustment knob.
Turn the adjustment knob
to the desired torque value.
Replace the cover over the
adjustment knob to secure
it during use. Confirm the
torque setting is accurate.
Determine the required torque for your application in foot pounds (ft.-lb.). Use the
conversion scale on the torque wrench to convert Nm to ft.-lb. If needed, use page 4
to convert other torque units to foot pounds.

Don't use extensions on the handle.
The torque measurement will be
inaccurate and the tool could
become damaged.
STOP applying torque when you hear and
feel a click. This means you’ve reached the
desired torque value.

APPLYING TORQUE
OPERATION
For off-axis tools, like a crowfoot
wrench, calculate a leverage
adjustment on page 5.
Attach a drive tool to the drive tang.
The flex joint provides clearance for
working around obstacles but, when
flexed, can reduce accuracy by up to
4 percent due to the offset from the
plane of rotation.
Engage the drive tool on the fastener
or fitting. For the most accurate
reading, the ratchet head must be
parallel with the wrench body.
Grip the center of the handle and apply
torque SLOWLY in a clockwise direction.
Don't use the torque wrench on
electrical circuits. The handle
doesn’t provide insulation from
electrical current.

• If the torque wrench is not used regularly, operate it several times at a low torque
setting to redistribute lubricant to the internal moving parts.
• The components in the handle are lubricated for life and should not be oiled. The
ratchet head may be lubricated for smooth use as needed.
• Clean the wrench by wiping it with a clean, dry, lint-free cloth. Do not immerse the
wrench in any type of liquid or cleaner to avoid damaging the internal components.
• The torque wrench should only be serviced or recalibrated by an accredited
measurement laboratory.
The ratchet head can be disassembled, if needed, for lubrication or service. Don’t
disassemble other parts of the wrench.

STORAGE
MAINTENANCE
• Store the torque wrench in the storage case in a dry location.
• The torque wrench can be stored at any torque setting because of its internal design.
By comparison, other torque wrenches, like click-style models, often have to be
stored at the lowest torque setting.

FORMULA INPUTS
The amount of leverage that's applied to a fastener is affected by the position of a
drive tool in relation to the torque wrench's drive tang. When using an off-axis tool that
doesn’t align with the drive tang, such as a crowfoot wrench, you may need to adjust
your torque setting.
T1 — Torque specification for the fastener
L— Effective length of the torque wrench
TRQ62103: L = 15.62 in.
TRQ62203: L = 19.22 in.
C— Change in length caused by a crowfoot wrench or other drive tool that
doesn’t align with the drive tang
T2 — Torque value you should use

If possible, align the
drive tool at a 90-degree
angle to the drive tang.
If a different angle is required, use one of the formulas
below to determine the appropriate torque value.
No formula is needed. Set
the torque value to the
fastener’s specification.
FORMULA OUTPUTS
Measure from the center of the fastener to the center of the drive tang in
a line parallel to the body of the wrench.
