AllStar Performance® ALL10590 - 220 V to 240 V Heated Tire Groover

BLADE INSERTION - Loosen the lever. The position of the lever may be adjusted by pushing the lever in and rotating it. Insert the blade between the spacers at a position that is roughly centered in the head. Blade depth can be accurately set by using a tire depth gauge. Avoid inserting the blade legs next to the thick black center spacer. If it is necessary to do this in order to cut a narrower groove, the center spacer may have to be replaced periodically. Tighten the lever firmly. Do not over tighten.

POWER LEVELS - Rubber durometer, blade size, depth of cut, and speed of cut are all variables that will affect your power level selection. Power level 4 is the least commonly used setting. Always cut at the lowest possible power level. Avoid smoke as this shortens blade life. A sharp blade will allow you to cut easier, faster, and with less heat. A dull or damaged blade should be replaced. IMPORTANT: For optimum performance and longevity of the groover, use only ALLSTAR replacement blades.

GROOVING - Place the cutting edge of the blade against the rubber. The groover will automatically activate when the operator applies cutting pressure. Allow the front slide pads to position the tool at the proper cutting angle. Most tire grooving is done with only the two front slide pads riding on the tire surface. The rear slide pad is only useful when cutting across soft tires, such as some racing tires, where the give of the tire may allow the rubber to contact the rear slide pad. The most common way to cut a zig zag groove is by an off and on action at the intersections. However, at low power settings, these same cuts can be made with a continuous action by maintaining cutting pressure through the intersections.
