LEXIVON LX-185 User manual

  • Hello! I've reviewed the user manual for the LEXIVON Torque Wrench LX-185. This document details the operation of a dual-range torque wrench with settings in both ft-lb and Nm and specifies its accurate use and maintenance. I'm ready to answer your questions about the tool and its operation, including setting torque, wrenching direction, proper storage, and accuracy details.
  • What is the accuracy of the torque wrench?
    How should I store the torque wrench?
    In what direction does the wrench measure torque?
    What should I do if the wrench has not been used for a long time?
    Can I use the wrench to loosen fasteners?

ATTENTION
Please read and understand entire manual,
including all safety information, before using
torque wrench. This tool is a precision measuring
instrument. Handle with care and store properly.
Do not attempt to increase leverage of this wrench
with any other device. Failure to follow all
instructions could result in damage to torque
wrench, property damage, or injury.
Wrench is shipped ready to use, calibrated and
tested to an accuracy of +/- 4%. To maintain this
accuracy, it is important that wrench is stored at
lowest torque setting, 30 ft.-lb. (40.7 Nm). This
setting relieves extra tension on the internal
spring, reducing fatigue that can adversely affect
accuracy.

This is a dual-range torque wrench marked with feet
pounds (ft.-lb.) and Newton meters (Nm) on opposite
sides of handle.
SETTING TORQUE READING
Foot Pounds (Example of setting 130 ft-lb)
1. Locate lock nut on the
end of handle. Unlock
knurled handle by turning
lock nut counterclockwise.
4. Lock torque setting by
turning lock nut clockwise
until snug. Wrench is now
set to measure 130 ft.-lb. of
torque and ready to use.
2. Turn knurled handle
until its top edge is even
with the horizontal “120”
mark on main scale and
the “0” mark on
micrometer scale is
centered on vertical line
of main scale.
3. The micrometer scale
divides the main scale
markings into 30 divisions.
Every micrometer scale
marking equals 2 ft.-lb.
To increase torque from
120 to 130, turn micrometer
handle clockwise until
"10" mark is centered on
vertical line of main
scale.
120 ft.-lb. (main scale) +
10 ft.-lb. (micrometer
scale) = 130 ft.-lb.
Setting desired torque on the Nm scale uses the
same procedure described above for ft.-lb. scale.
The micrometer scale divides the main scale
markings into 30 divisions. Every micrometer scale
marking equals 2.7 Nm.
To set a torque value of 130.0 Nm, turn knurled
micrometer handle until top is aligned with
“122.0” mark on main scale and the “0” mark on
micrometer scale is centered on vertical line of
main scale.
To increase torque from 122.0 Nm to 130.0 Nm,
turn micrometer handle
clockwise until the “3”
mark is centered on
vertical line of main
scale. 130.0 Nm – 122.0
Nm = 8.0 Nm. 8.0 Nm /
2.7 = 3 micrometer scale
markings. Wrench is now
set to measure 130.0
Nm of torque and ready
to use.

WRENCH OPERATION
1. Install proper socket/attachment on the square
drive and apply to nut/bolt. Make sure to keep
your tightening hand is centered on the knurled
handle for accurate results.
2. Operate the wrench to tighten nut/bolt and
slow operation when they became snug to a
smooth and steady pull. When a ‘CLICK’ or
‘IMPULSE’ is heard or felt, stop pulling wrench and
release pressure on handle.
3. Wrench will automatically reset for next
operation after pressure is released.
4. IMPORTANT OPERATION NOTICE:
Operating wrench too quickly or with too much force
may cause you to miss the exact torque setting.
Do not continue to pull after torque setting is
reached. Doing so will damage wrench internal
mechanism.
At low torque settings, click can be subtle. Use
wrench in a quiet environment.
Do not use torque wrench to loosening fasteners.
Torque is measured in CLOCKWISE direction only!
Tighten/adjust lock nut and knurled handle by
hand only.

MAINTENANCE AND STORAGE
1. If wrench has not been used for a long period of
time, operate it several times at a low torque
setting. This will allow internal lubricant to recoat
internal components.
2. Keep the Torque Wrench Scale
at the lowest setting when not in
use. The lowest setting: 30 ft.-lb.
mark on the main scale and ‘0’
mark on the micrometer scale.
DO NOT turn handle below
lowest torque setting.
3. This wrench is a precision measuring
instrument. Take care to operate wrench correctly.
Store in a clean, dry environment.
4. Clean wrench by wiping with a clean, dry, lint-free
cloth. Do not immerse in any type of liquid or cleaner.
This may damage the internal components of the
wrench.
CAUTION:
PRECISION TOOL - Do not use for extreme operation
like breaking loose stuck fasteners.
PRACTICE FIRST - Try wrench on a non-critical fastener
first to learn how it works.
OPERATE SLOWLY - Wrench “clicks” to notify when
torque value is reached. Wrench does not stop applying
force automatically.
LISTEN AND FEEL - At low torque settings clicks is subtle.
Learn to hear and feel the click.
STORE AT LOWEST SETTING - To maintain calibration,
set wrench to lowest torque value before storage.
MEASURES IN ONE DIRECTION - Wrench only
measures torque in right hand (clockwise) direction.
