Operation

Operation

The GrindLazer is designed to plane flat, horizontal con­crete 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).

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).

1. Slide replacement Drum onto hex shaft.

2. Replace 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.

Cutting Drum Assemblies

S

S

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

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.

Carbide Flail Cutter/Assembly

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

Carbide Miller Cutter/Assembly

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

Cutting Drum Assemblies

NOTE: Each increment on Drum Adjustment Dial (D) is

0.010 in. (0.25 mm) depth change of cutting drum.

Diamond Blade Assembly
(480/630 Models Only)

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

NOTICE

Diamond Blades are designed to be cooled by air­flow 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.

Cutter and Drum Assemblies

• 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 sur­faces.

Handle Bar Adjustment

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

Maintenance

ti14760a

Maintenance

Avoid touching engine and drum after use until they
have completely cooled.

The following steps should be performed to maintain
proper operation and sustain the life of the GrindLazer.

BEFORE OPERATION:

• Visually inspect the entire unit for damage or loose
connections

• Insert grease into the grease fittings on the drum
mount and center hinge

• Check engine oil (see engine manual)

• Check drum bushings and cutters

• Check drum for uneven wear

• Check for proper tire pressure

DAILY:

• Insert and clean air filter element

• Clean dust and debris from exterior of unit (do NOT
use pressure washer or other high pressure clean­ing equipment)

• Check engine oil level and fill as necessary

• Check and fill gas tank

• Remove air filter cover and clean element. Replace
element if necessary. Replacement elements can
be purchased from your local engine dealer.

AFTER THE FIRST 20 HOURS OF OPERATION:

• Drain engine oil and refill with clean oil. See engine
manual for correct viscosity.

EVERY 40-50 HOURS OF OPERATION:

• Change engine oil (see engine manual)

• Grease wheel bearings

AS REQUIRED:

• Check drive belt and tension and tighten or replace
as needed

For additional information about engine mainte­nance, see Honda (270 and 390 models) or Briggs
and Stratton (480 models) engine manual.

Caster Wheel Maintenance

EVERY MONTH:

• Grease wheel bearing

• Check pin for wear. If pin is worn out there will be
play in caster wheel. Reverse or replace pin as
needed.

• Check caster wheel alignment as necessary. To
align: loosen set screw, align wheel, and tighten
screw.

Front Swivel Tire Alignment

1. Loosen cap screw.

2. Rotate front wheel fork left or right, as necessary, to
straighten alignment.

3. Tighten cap screw. Push GrindLazer and let it roll
with hands off of GrindLazer.

NOTE: If GrindLazer rolls right or left, repeat steps 1
and 3 until GrindLazer rolls straight.
