1/2" DRIVE TORQUE WRENCH
25-250 FT/LBS.
TORQUE WRENCH PREPARATION
INSTRUCTIONS
NOTE: The scale on the shaft of the torque wrench is
referred to as the Main Scale. The scale on the adjustable
handle is referred to as the Micrometer Scale.
NOTE: The Lock Nut should be tightened by hand.
DO NOT attempt to tighten the Lock Nut using a wrench
or power tool, as this may lead to product damage or
malfunction.
FOOT POUND SETTINGS
1. Loosen the Lock Nut located at the end of the Handle.
2. COARSE SCALE ADJUSTMENT: Rotate the handle
clockwise until the “0” mark on the Micrometer Scale
meets the lowest setting (25 Ft/Lbs.) on the Main Scale.
The vertical markings on the Micrometer Scale and
Main Scale should align.
NOTE: This torque wrench will not measure torque below
25 Ft/Lbs.
3. FINE SCALE ADJUSTMENT: The Micrometer Scale
is divided into 25 divisions. Each marking represents
1 Ft/Lb.
a. EXAMPLE SETTING: Increase the torque setting
from 75 Ft/Lbs. to 90 Ft/Lbs.
i. Rotate the handle clockwise until the “0”
marking on the Micrometer Scale is aligned
with the Main Scale at 75 Ft/Lbs.
ii. Continue to rotate clockwise until the
vertical marking “15” on the Micrometer
Scale is aligned with the vertical line on
the Main Scale.
iii. 75 Ft/Lbs. (Main Scale) + 15 Ft/Lbs.
(Micrometer Scale) = 90 Ft/Lbs.
4. Tighten the Lock Nut.
NEWTON METER SETTINGS
1. Loosen the Lock Nut located at the end of the Handle.
2. COARSE SCALE ADJUSTMENT: Rotate the handle
clockwise until the “0” mark on the Micrometer Scale
meets the lowest setting 33.9 N•m on the Main Scale.
The vertical markings on the Micrometer Scale and
Main Scale should align.
NOTE: This torque wrench will not measure torque
below 33.9 N•m.
3. FINE SCALE ADJUSTMENT: The Micrometer Scale
is divided into 25 divisions. Each marking represents
1.35 N•m.
a. EXAMPLE SETTING: Increase the torque setting
from 101.7 N•m to 128.8 N•m (approx.).
i. Rotate the handle clockwise until the “0”
marking on the Micrometer Scale is aligned
with the Main Scale at 101.7 N•m.
ii. Continue to rotate clockwise until the vertical
marking “20” on the Micrometer Scale is
aligned with the vertical line on the Main
Scale. (20 x 1.35 N•m ≈ 27.1)
iii. 101.7 N•m (Main Scale) + 27.1 N•m
(Micrometer Scale) ≈ 128.8 N•m
4. Tighten the Lock Nut.
