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. 5 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. 3.

NOTE: Drum clutch will not engage when engine is running at idle. 480 Models: LineDriver must be attached to GrindLazer. 8 3A0101B Operation Depth Control Wheels How to Level the Drum Using Depth Control Wheels as a 5 in. or 10 in. Wide Cutting Guide To make a 5 in. cut, install two spacers (S) on outside of Depth Control Wheels (K). K To properly level the drum, GrindLazer must be resting on a flat level surface. 1.

Check for worn or damaged parts and perform any required Maintenance, page 12. ti14758a 2. Slide Engine Throttle Lever (A) to low setting. ti6482a 10 3A0101B 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 several 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 Models Only) Watch Depth Control Wheels (K) during operation; if wheels are spinning, proper depth is being achieved. NOTICE Handle Bar Adjustment To adjust handle bar: remove four screws (S), slide handle bar to desired height, and replace screws and tighten. 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. S 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. 3A0101B S 11 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: • Visually inspect the entire unit for damage or loose connections • Check engine oil (see engine manual) AS REQUIRED: • Check drum bushings and cutters • • Check drum for uneven wear • Check for proper tire pressure ti14760a For additional information about engine maintenance, 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 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 Check drive belt and tension and tighten or replace as needed 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. 12 3A0101B Technical Data Technical Data GrindLazer 270 (Model 571002) Dimensions Unpackaged Packaged Height in./cm: 46 (116.8) 50.5 (128.3) Width in./cm: 28 (71.1) 37 (94.0) Length in.cm: 62 (157.5) 73 (185.4) Weight lb/kg: 300 (136) 400 (181) Noise (dBa) Sound Power per ISO 3744: 107.3 Sound Pressure measured at 91.6 3.1 feet (1m): Vibration (m/sec2) per ISO 3744 Without LineDriver: 7.9 With LineDriver: 8.3 Power Rating (HorsePower) per SAE J1349 8.0 @ 3600 rpm GrindLazer 390 (Model 571003) Dimensions Unpackaged Packaged Height in./cm: 46 (116.8) 50.5 (128.3) Width in./cm: 28 (71.1) 37 (94.0) Length in.cm: 62 (157.5) 73 (185.4) Weight lb/kg: 310 (141) 410 (186) Noise (dBa) Sound Power per ISO 3744: 109.3 Sound Pressure measured at 93.6 3.1 feet (1m): Vibration (m/sec2) per ISO 3744 Without LineDriver: 7.5 With LineDriver: 5.9 Power Rating (HorsePower) per SAE J1349 11.0 @ 3600 rpm GrindLazer 480 (Model 571004) Dimensions Unpackaged Packaged Height in./cm: 46 (116.8) 50.5 (128.3) Width in./cm: 28 (71.1) 37 (94.0) Length in.cm: 62 (157.5) 73 (185.4) Weight lb/kg: 330 (150) 430 (195) Noise (dBa) Sound Power per ISO 3744: 108.6 Sound Pressure measured at 92.1 3.1 feet (1m): Vibration (m/sec2) per ISO 3744 With LineDriver: 4.9 Power Rating (HorsePower) per SAE J1349 16.0 @ 3600 rpm Maximum storage time, years Maximum lifetime, years Power efficiency factor 3A0101B 5 10 200 ground meters per liter fuel 13 Graco Standard Warranty Graco warrants all equipment referenced in this document which is manufactured by Graco and bearing its name to be free from defects in material and workmanship on the date of sale to the original purchaser for use.
