• Designed for more efficient cleaning, routing and repairing of cracks in concrete and most other building materials.
• Leaves a V-shaped pattern for filling.
• 5/8-11 threaded arbor fits right angle grinders.

• 4-1/2 x 5/8-11 threaded, 13,300 max Rpm.
• 7 x 5/8-11 threaded, 8,500 max Rpm.
• 100% GE diamond matrix for superior cutting performance.
• Precision balanced.
• Easy to spin on/off grinder.
• Diamond matrix is designed for consistent even wear.
• Using Pearl’s unique Direct Sintering Technology (DST™) the Crack-Chaser™ is manufactured so that the diamond matrix is molecularly bonded directly to the core.
• Because there are no segments to fly off the Crack-Chaser™ is the safest, most effective product for re-routing cracks and crevices.
• The Crack-Chaser™ has been engineered to quickly sink into cracks and crevices.
• Simply place the wheel on the crack and let the diamonds do the work.
• The special design enables the crack-Chaser™ to produce a 1/2” wide 70° V-shaped groove.
• This has proven to be the most effective configuration for re-caulking and re-filling.

Engine

• Yanmar 48 hp 4-cylinder, liquid-cooled, diesel engine meets current EPA requirements.
• 42 hp at the blade shaft

• Three-speed gearbox utilizes the patented power transmission system which has a right angle gearbox configuration.
• Patented power transmission system has a right angle gearbox configuration with 12 V-belts. This transmits more power to the blade shaft than similar models in its class, delivering 42 hp at the blade shaft.

• Gear selections for different blade diameters are clearly identified with numbers and colors.
• Positive locking-detent for gearbox shift lever eliminates possibility of slipping out of gear.
• Two neutral positions assist in freeing blades stuck in a cut and allows saw operation without the blade rotating.
• The patented IntelliSeal™ blade shaft system allows for a minimum 500-hour service interval, eliminates daily greasing of bearings and also has a quick disconnect blade flange.
• Patent-pending multi-positional handlebars easily adjust to individual operator’s preference which increases operator comfort and reduces operator fatigue.
• Balanced dual motor hydrostatic drive system eliminates surging and lag while cutting - with no belts, chains or gears; requires no adjustment.
• Front pivot model has a patent pending electric tracking system option, which allows operator to make tracking adjustments with a switch while cutting.

Gearbox shift lever is used to change output speed of the engine gearbox. Three speeds and two neutral positions are standard. Gearbox shift lever positions (1, 2 and 3) are color coded to match the blade diameter and blade-shaft rpm decal located on the control panel.
Power transmission system has a right angle gearbox configuration.
