3. SPECIFICATION
WARNING! DO NOT
use the torque wrench if damaged or thought to be faulty.
Ensure all workshop safety rules, regulations and conditions are complied with when using the torque wrench.
Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.
Keep children and unauthorised persons away from the working area.
Avoid over-torquing the wrench (110% of maximum torque range) as this will cause loss of accuracy.
Keep the wrench away from magnets.
In operation when you hear the continuous tone, stop pulling immediately especially in case the target torque/ angle is low.
Ensure all sockets, extensions and drivers are rated correctly and are of flawless construction. Avoid using adaptors and extensions for
best accuracy.
DO NOT
use the torque wrench if the batteries are low, torque accuracy will be affected.
DO NOT
use the wrench as a hammer or similar.
DO NOT
use on live electrical circuits the plastic handle is not insulated.
DO NOT
subject the wrench to excessive force or shocks.
DO NOT
drop, throw, or violently shake the wrench.
DO NOT
operate
the wrench in damp conditions.
DO NOT
operate the wrench in dusty conditions.
DO NOT
push on the LCD panel.
DO NOT
use wrench until first instructed in its use by a qualified person.
DO NOT
leave the wrench in a place exposed to excessive heat, humidity or direct sunlight.
DO NOT
use organic solvents such as alcohol or thinners to clean the wrench.
After use, turn the wrench off, clean with a soft dry cloth, place torque wrench in its storage case, and store in a safe, dry, childproof
location.
Remove the batteries if the torque wrench is not to be used for a long time, to prevent damage from leaking.
Rugged and resilient digital torque wrench suitable for workshop and factory use. LCD read-out with LED, audible alarm and vibration indicat-
ing achieved and target torque levels. 180° Flexi-head for increased access in hard to reach applications. Features angle mode, eliminating
the need for angle gauges and protractors providing an accurate and fast way to measure torque plus angle tightening sequences. It will also
accumulate angle measurement when multiple turns are required, ideal for use where access is limited. Selectable track or peak modes and up
to 5 user preset memories available. Read-outs in Nm, lb.in, lb.ft, kgf.m or degrees. Reversible Chrome Vanadium 72-tooth ratchet allows torque
reading in either direction. Accurate to ±2% between 10% and 100% of wrench’s stated capacity. Supplied with test certificate and storage case.

We recommend to ensure continued accuracy the
calibration of the wrench should be checked annually,
beginning one year after the first time of use. Calibration
should also be checked after any impact,
over-torquing or other misuse. Contact your Sealey
Dealer to arrange recalibration.
