SAFETY INSTRUCTIONS
WARNING: Risk of Flying Particles
Over torquing can cause breakage. Force against flex
stops on flex head can cause head breakage. An out
of calibration torque wrench can cause part or tool breakage.
Broken hand tools, sockets or accessories can cause injury.
Excess force can cause crow foot or flare nut wrench slippage.
READ THIS MANUAL COMPLETELY BEFORE
USING THE DIGITAL TORQUE WRENCH
• For personal safety and to avoid wrench damage,
follow good professional tool practices.
• Periodic recalibration is necessary to maintain tool
accuracy.
• Users and bystanders should always wear eye
protection.
• Be sure all components, including adapters, extensions,
drivers and sockets are rated to match or exceed the torque
being applied with tool.
• Observe all equipment, system and manufacturer's warnings,
cautions and procedures when using this wrench.
• Always use the correct size socket for the fastener being
torqued.
• Do not use damaged sockets, showing signs of wear or
cracks.
• Always replace damaged fasteners before applying torque.
WARNING: To Avoid Damaging
Digital Torque Wrench
• Never operate wrench when powered OFF. Always power
wrench ON prior to applying torque.
• Do not press ON/ZERO key while torque is being applied.
• Never use this wrench to loosen fasteners.
• Never use extensions, such as a pipe, on the handle of the
wrench.
• Always make sure the ratchet Forward/Reverse Switch is
fully engaged in the correct position.
• Always verify that the wrench capacity matches or exceeds
each application before proceeding.
• Always verify the calibration of the wrench if you know or
suspect its capacity has been exceeded.
• Never force the head of flex head drives against stops.
• Always pull - do not push - on the wrench handle and adjust
your stance to prevent a possible fall while applying torque.
WARNING: Electrical Shock Hazard
• Electrical shock can cause injury.
• Plastic handle is not insulated.
• Do not use on live electrical circuits.
INTRODUCTION
The Electronic Torque Wrench digitally displays fastener
torque specification settings, torque readings and peak hold
measurements.
DISPLAY: The wrench features a custom LCD (Liquid Crystal
Display) display, use keypad to select torque units, readout in
ft.lb., in.lb., Nm, and kg.cm. Display also includes a 10 segment
bar graph.
E N G L I S H •
SETTING: Determine torque specification for fastener. Next,
use the (
) UP or (
) DOWN arrow keys to scroll to the
desired target torque value.
NOTE: The target torque value is adjustable between 10% and
100% of full scale. The scrolling display rolls over at both ends
for quick and convenient adjustment of setting.
TRACKING: While torque is applied, the display switches from
preset value to actual applied value with a 0.20 second update
rate.
AUDIBLE TONES AND LED'S: When the applied torque
value equals -10% of the target torque value, a YELLOW
LED illuminates. When the target torque value is reached,
the wrench outputs a 0.50 (1/2) second audible tone and the
GREEN LED illuminates. At +10% of target torque the RED LED
illuminates.
PEAK HOLD: When torque is released the display holds and
flashes the peak torque reading for 10 seconds or until next
torque is applied.
OVERLOAD: If the wrench is used beyond 100% of full scale
the audible tone will pulse rapidly to warn the operator to stop.
At 125% of full scale the display will lock and read "- - - -".
ZERO: Wrench will automatically perform self calibration
check and re-zero when powered ON. When powered ON, the
wrench can be re-zeroed at any time by depressing the ON/
ZERO key.
SETUP MEMORY: When powered ON, the wrench returns to
the last unit and torque setting selected.
BATTERY: The Torque Wrench uses two (2) standard
replaceable "CR123" lithium cells which provide more than
80 hours of continuous operation. The current battery level
can be determined by viewing the battery indicator icon in the
upper left corner of the LCD display. A flashing "bATT" display
means the wrench is no longer accurate and the battery must
be replaced before continuing usage of wrench.
POWER ON: Depress and hold the ON/ZERO key until display
illuminates.
POWER OFF: Depress the ON/ZERO key and hold for 5
seconds.
AUTO POWER OFF: Auto power OFF will occur after 2
minutes of non usage to conserve battery power.
OPERATOR INSTRUCTION
SET-UP:
1. To power wrench ON, depress the ON/ZERO key - the wrench
will seft-test and display the last unit and torque setting
selected.
2. Select the desired units by depressing the UNITS key. Each
time the UNITS key is depressed, a different unit of measure is
displayed - (ft.lb., in.lb., Nm, or kg.cm.)
3. Pre-select desired torque value by depressing and holding
the ( ) UP or ( ) DOWN key. The scrolling display rolls over
at both ends for quick and convenient adjustment of setting.
4. Tool set-up is complete, wrench is ready for use. IMPORTANT:
Proper hand position when grasping wrench is necessary to
ensure highest wrench accuracy. Position hand so that it is
centered on the gripped portion of handle. AVOID GRASPING
WRENCH ABOVE OR BELOW GRIPPED PORTION OF HANDLE.
