Operation
3A0101F 5
Operation
The GrindLazer is designed to plane flat, horizontal con-
crete or asphalt slabs.
GrindLazer 270 (270 cc) and GrindLazer 390 (390 cc)
models are designed to be operated by a single
operator positioned at the back of the unit, or in
conjunction with LineDriver. GrindLazer 480 (480 cc)
and GrindLazer 630 (627 cc) can ONLY be operated
with LineDriver.
Maintain a safe operating distance from other people in
the work area. Avoid any pipes, columns, openings, or
any other objects protruding from work surface.
Start-Up
Before starting engine, perform the following:
• Read and understand engine manual
• Make sure all guards are in place and secure
• Make sure all mechanical fasteners are secure
• Inspect for damage to engine and other exterior
surfaces
• Use correct cutters for each job. Make sure drum is
balanced and the correct number, size and type of
cutter wheels are being used. Make sure drum shaft
is locked and secured.
• Inspect work area to locate any pipes, columns,
deck inserts, or other objects protruding from work
surface. Avoid these objects during operation.

Drum Installation/Replacement
Installation
NOTE: Carbide Flail Cutter drums do not require
specific orientation or direction. Carbide Millers and
Diamond Blades are directional. They should be
stacked so that the arrows on the Millers and Blades
face the same direction as the rotation of the drum.
270 and 390 models are designed for “forward cut”
grinding (the drum rotates in the same direction that it
travels). 480 and 630 models are design for “reverse (up
cut)” grinding (the drum rotates in the opposite direction
that it travels).
1. Slide replacement Drum onto hex shaft.
2. Replace Drum Access Panel (H).
3. Lower Drum Adjustment Dial (D) and pull Drum
Engage Lever (E) so drum rests on ground.
Door pin and hole should line up.
4. Tighten four bolts on Drum Access Panel (H).
5. Turn Drum Adjustment Dial (D) to maximum height.
Removal
1. Remove four bolts and Drum Access Panel (H).
2. Slide drum off of hex shaft.
