Owner's Manual Model No: H3DTWDIG
SAFETY RULES
1. STUDY THIS BOOKLET CAREFULLY BEFORE ATTEMPTING
TO OPERATE THIS WRENCH.
2. Never apply more torque than the maximum scale
reading.
3. This torque wrench is designed for manual tightening of
threaded fasteners only. DO NOT USE IT AS A NUTBREAKER
OR FOR ANY OTHER PURPOSE.
4. Over-torqued or defective fasteners and sockets may
suddenly break. Ratchets that are improperly engaged,
worn out, damaged, or over-torqued may slip or break.
TO PREVENT INJURY, KEEP PROPER FOOTING AND
BALANCE AT ALL TIMES. DO NOT USE THE WRENCH IN
PLACES FROM WHICH YOU MAY FALL OR SLIP, OR
AROUND OPERATING MACHINERY.
5. This wrench will not prevent you from applying more
torque than set, it is not a torque limiting tool. The LCD
display will flash "STOP" if you exceed either the lower or
upper limit of intended use. At low settings the release is
gentle and there usually is no audible 'click' signal. Learn
how different amounts of torque 'feel', so you will reduce
the possibility of damage and/or injury due to accidental
over-torquing.
6. APPLY FORCE TO THE GRIP ONLY. DO NOT USE 'CHEATER
BARS' (a piece of pipe placed over the hand grip).
7. There are no user-serviceable components inside the
wrench. Disassembling the wrench or making any
adjustments will result in the loss of accuracy, and will
void the warranty.

TO SET TORQUE
1. Press the red PWR button to turn the wrench on.
2. At initial power up, the LCD display will flash all icons
twice and then show the current torque setting. When
stored or not in use, the wrench should be set to less
than 25% of the maximum capacity.
NOTE: The battery level indicator on the LCD display will
indicate the remaining battery life.
3. Press the green UNIT button to toggle through desired
units (ft-lb, in-lb, N-m, kg-cm)
4. Pull the adjusting knob out to unlock the adjusting
mechanism.
5. While holding the adjusting knob unlocked, turn it
clockwise to increase the torque, and counterclockwise
to decrease torque. Keep turning until the desired
TARGET torque reading is displayed on the LCD screen.
6. If during a torque setting adjustment the intended
TARGET value is exceeded on the LCD display, the
torque wrench should be first adjusted back to below
the TARGET value, and then back up to the intended
TARGET value.
7. Lock the setting by releasing and, if necessary, pushing
the adjusting knob in. The knob can be turned slightly
back and forth without changing the torque setting to
assure proper engagement of teeth in the locking
mechanism.

TO APPLY TORQUE
1. Attach the proper socket or other attachment to the
drive. Set the reversing lever of the proper direction of
the operation.
NOTE: If special attachments are used, torque setting must
be corrected in accordance with the directions given below
in the extensions section.
2. Place the socket or attachment onto the fastener to be
torqued.
3. Utilizing the ratcheting head, you may 'spindown' the
fastener until resistance is felt.
4. Holding the wrench BY THE GRIP ONLY*, apply SLOW
AND STEADY pull until a momentary release impulse or
'click' is felt. Release tightening pressure immediately
when the release is felt.
WARNING: At low torque settings the release is gentle and
there usually is no audible 'click' signal. Learn how the
release feels BEFORE you torque to avoid accidental
overtightening or damage.
*When using long sockets or extensions, the wrench may be
supported at the head (only at the head) with only negligible
effects on accuracy.
5. The wrench resets automatically and is ready for the next
operation.
