Torque Control Impact Wrenches EIT with Hydraulic torsion control system HTC
Features and benefits
Links to other products and information
New Innovative and patented, built-in hydraulic torque control device
Each tool features pre-set torque settings to cover a practical torque range with an accuracy of +/- 10%
Torque repeatability is +/- 5%
Only one tool required for torque controlled tigthening and full torque when loosening bolts in reverse
Easy to use torque selector
Once torque is selected the tool will reach the required torque within seconds - but compared to regular impact wrenches the torque build-up is eliminated due to the integrated hydraulic torsion mechanism
Extremely fast operating speed due to special motor design
Cost effective, very affordable compared with regular torque tools
Accurate, powerful, very fast, versatile and affordable
A new innovative and patented built-in hydraulic torsion control device allows these tools to be used for torque
controlled tightening and high power loosening of bolt connections. Each tool has preset torque
settings to cover a practical torque range with an accuracy of +/- 10% when tightenting bolts. In
reverse full power is available to undo even the most stubborn bolts. Suited not only for automotive applications such as torque controlled tightening of wheel studs but also for industrial applications where high speed, accuracy and value for money is important.

How to use the tools and how to select the torque to ensure accurate bolt connections
Models EIT 2171, 2213, 2261, 2364 - preset torque settings
1. Set up the air pressure to 6.2 bar - 90 PSI
2. Set the torsion control valve to the “TORSION” position (see picture C)
3. Set the air control valve (see picture D) from No. 1, 2, 3 or 4 to select the desired torque
value (see picture D)
4. Tighten the bolts, check for torque value using a torque wrench if required
5. If full torque is required set the control valve to F for forward (see picture C)
6. To loosen bolts set the control valve to R for Reverse - full torque is available in reverse
Models EIT 6324, 2447 - variable torque settings
as per instructions above, but torque value is infinetly variable by adjusting the torsion
control valve as well as the air control valve to obtain a desired torque value.
