ANLEITUNG ZUM SCHNEIDEN VON REIFEN

You will need the following tools and components to recut the profile:

• Tire tread cutter (we recommend RUBBER-CUT 414 PRO)

• Profile cutting blades (we recommend using original REMA TIPTOP cutting blades)

• Blade setting gauge (anchored in the RUBBER-CUT 414 PRO)

• Allen key (anchored in the RUBBER-CUT 414 PRO)

• Tool for removing stones, nails, etc. from the profile grooves

• Optional tread depth gauge

• Optional the tire stand (we recommend RUBBER-CUT STATION)

Check whether the "REGROOVABLE" marking is on the tire sidewall. If this is not available there, contact the respective tire manufacturer. All truck, commercial vehicle and large tires suitable for regrooving are marked with "REGROOVABLE" (= regroovable).

Please check the tire for any damage to the sidewall and tread. Also check the profile for any dirt and remove it carefully if necessary.

Tires with strong one-sided abrasion, larger washouts Brake plates are not suitable for regrooving.

Measure the tread depth in the main grooves to determine the lowest depth of the tire tread. The following options are available to determine the setting depth of the profile cutter for the cutter head on the profile cutter:

1. Regrooving instructions in mm from the tire manufacturer + measured tread depth

2. Measure the depth with the tread depth gauge directly in the regrooving indicator of the tire (at the point with the most wear). The measured value should correspond to the cutting depth setting of the cutting knife. Get more information from the tire manufacturer.

Regrooving indicators / measuring points are available on truck tires at a distance of approx. 30 - 40 cm around the regroovable tire.

Select the blade shape and size according to the regrooving instructions.

W 1-6 = protractor, cutting width 3-28 mm
R 1-5 = circular knife, cutting width 3-14 mm

Set the previously determined depth as the knife height and use the knife setting gauge for this.

Before you clamp or remove a cutter from the tire tread cutter, always make sure that the device is switched off.

Make sure that the free hand is not in the cutting area of the trimmer. This hand is ideally located on the lower edge of the tire or as an additional guide on the handle.

Use the Allen key to open the cylinder screws to fix the clamping jaws on the front of the cutting handle and cutter head. Push in the profile cutter and set the desired height with the knife setting gauge. The cutting width of the knife can also be varied slightly. Then tighten the cylinder screws again.

With certain knives, it can also be advantageous to turn the clamping jaws completely by 180 degrees.

Cut about 15 cm from the profile and remove the cut rubber. (Now measure with a depth gauge) and check that the tire casing is not damaged. Usually the longitudinal / main profile grooves are cut first and then the transverse grooves.

Set the power levels (4x2 levels for the RUBBER-CUT 414 PRO) from low to high depending on the blade width, material strength and wear of the blade.

Now cut the tire using the manufacturer's / tread pattern.

After the tire has been completely re-cut, check the re-cut profile again for cut quality and damage to the tire carcass.
