Replacement, page 6).  
To make a 5 in. cut, install two spacers (S) on outside  
of Depth Control Wheels (K).

Cutting Drum Assemblies  
Cutting Drum Assemblies  
NOTE: Each increment on Drum Adjustment Dial (D) is  
0.010 in. (0.25 mm) depth change of cutting drum.  
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 sev-  
eral thin passes. A single pass should be no deeper  
than 1/32 in. or damage to rods and cutters could occur.  
Diamond Blade Assembly  
(480/630 Models Only)  
Handle Bar Adjustment  
Watch Depth Control Wheels (K) during operation; if  
wheels are spinning, proper depth is being achieved.  
To adjust handle bar: remove four screws (S), slide  
handle bar to desired height, and replace screws and  
tighten.  
NOTICE  
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.  
S
Cutter and Drum Assemblies  
S
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.

Maintenance  
Maintenance  
Insert grease into the grease fittings on the drum  
mount and center hinge  
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:  
ti14760a  
Visually inspect the entire unit for damage or loose  
connections  
Check engine oil (see engine manual)  
Check drum bushings and cutters  
Check drum for uneven wear  
AS REQUIRED:  
Check drive belt and tension and tighten or replace  
as needed  
Check for proper tire pressure  
For additional information about engine mainte-  
nance, see Honda (270 and 390 models) or Briggs  
and Stratton (480 models) engine manual.  
DAILY:  
Insert and clean air filter element  
Clean dust and debris from exterior of unit (do NOT  
use pressure washer or other high pressure clean-  
ing equipment)  
Caster Wheel Maintenance  
EVERY MONTH:  
Check engine oil level and fill as necessary  
Check and fill gas tank  
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.  
Remove air filter cover and clean element. Replace  
element if necessary. Replacement elements can  
be purchased from your local engine dealer.  
Check caster wheel alignment as necessary. To  
align: loosen set screw, align wheel, and tighten  
screw.  
AFTER THE FIRST 20 HOURS OF OPERATION:  
Drain engine oil and refill with clean oil. See engine  
manual for correct viscosity.  
Front Swivel Tire Alignment  
EVERY 40-50 HOURS OF OPERATION:  
1. Loosen cap screw.  
Change engine oil (see engine manual)  
Grease wheel bearings  
2. Rotate front wheel fork left or right, as necessary, to  
straighten alignment.  
3. Tighten cap screw. Push GrindLazer and let it roll
