Cutting Drum Assemblies

Different drum configurations can be used for different 
applications. There are three different types of drum 
assemblies compatible with the GrindLazer: carbide 
flails, carbide millers, and diamond blades.

Gradually adjust depth down to remove marking line 
(minimal amount of paved surface should be removed).

Best results for deep cuts are achieved by making sev-
eral thin passes. A single pass should be no deeper 
than 1/32 in. or damage to rods and cutters could occur.

Watch Depth Control Wheels (K) during operation; if 
wheels are spinning, proper depth is being achieved.

•

The engine should not labor. Run engine at full 
speed and adjust forward speed to fit the work being 
performed. Harder concrete surfaces will have to be 
cut at a slower pace than asphalt or other softer sur-
faces.

NOTE: Each increment on Drum Adjustment Dial (D) is 
0.010 in. (0.25 mm) depth change of cutting drum.

To adjust handle bar: remove four screws (S), slide 
handle bar to desired height, and replace screws and 
tighten.

Avoid touching or handling drum after use until it has 
completely cooled.

Diamond Blades are designed to be cooled by air-
flow around the blades. Lift blade out of cut every 10 
to 15 seconds, then run at full speed for several 
seconds to prevent excessive heat build-up which 
could damage the blades.
