Note on tools

If the ratchet is too expensive for you:

You are most likely to find large special tools at farmers, truck drivers or garages that specialise in agricultural vehicles.

If you don’t have a ratchet, you can also use an extended pipe wrench to tighten the screw. The pipe wrench must be super sturdy and at least 50 cm long. Working with a pipe wrench is very tedious.

Use the pipe wrench only on the nut and not on the shaft of the GTS, the resulting grooves and edges on the shaft can block the accessories / rings!

The screwing in of the screw only works manually, even strong hydraulic percussion drills do not bring up the power and overheat – we have tried a lot 😉
