description:the wrench is made of chrome-vanadium steel which ensures its durability and strength. It has a mechanical torque ratchet which when the desired tightening force is reached jumps one notch producing a characteristic sound.the torque scale is located in the wrench handle and is adjusted by turning it. After setting the desired torque lock the wrench with the safety catch at the end of the handle.the wrench is gs certified.comparison of torques in various units of length and force:1 kgf*cm = 13.887 oz*in (ounce x inch)1 kgf*cm = 0.867 lb*in (pound x inch)1 kgf*m = 9.80665 n*m (newton x meter)1 kgf*m = 7.233 lb*ft (pound x foot)1 ft*lb = 12 lb*in (pound x inch)1 dm*n = 14.16 oz*in (ounce x inch)application:it is mainly used in automotive technology for precise fastening and wherever the manufacturer specifies the required tightening torque for the connection.how to use:- select the appropriate nm or in-lbs scale. Unlock the micrometer knob.- set the micrometer knob so that 0 on the knob's scale aligns with the vertical line on the wrench arm.- turn the micrometer knob clockwise until the desired torque is set. The desired torque is set when the scale on the micrometer knob aligns with the vertical line on the wrench arm.- then lock the micrometer knob and set the appropriate direction of rotation of the ratchet; after that the wrench is ready for use.- place the appropriate socket on the wrench driver. During tightening the wrench clicks when the set torque is reached. If you hear or feel a click stop tightening.package contents:- torque wrench- factory calibration certificate (individual for each wrench marked with the wrench's serial number)- user's manual- warranty card- carrying casetechnical data:- index number yt-0750- gross weight (kg) 1.1250- length [mm] 366- drive size [inch] 3/8- torque value [nm] 19-110
