Husqvarna FS6600D Operators Manual

The Husqvarna FS6600D is a professional-grade, walk-behind floor saw designed for cutting concrete, asphalt, and other hard materials. It features a powerful engine, a 26-inch cutting blade capacity, water feed system for dust control, ergonomic handles, and robust construction for demanding job sites. Below are key sections for safety, features, operation, maintenance, and troubleshooting.

Features at a Glance

Key components: Heavy-duty frame, 26-inch diamond blade, Honda GX390 engine (or equivalent), water pump and tank, depth adjustment handle, transport wheels, and front guide wheel.

Safety Instructions

Read and understand all instructions before operation. Failure to follow warnings can cause serious injury or death.

1. Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, gloves, steel-toed boots, and a respirator when cutting.
2. Work Area: Keep bystanders, especially children, at a safe distance. Ensure adequate lighting and ventilation.
3. Machine Inspection: Check for loose parts, damaged blade, fuel leaks, and proper guard installation before each use.
4. Kickback Hazard: Never stand directly behind the saw. Hold handles firmly with both hands during operation.
5. Blade Contact: Do not force the blade. Let the blade cut at its own speed. Never cut without water (for wet cutting applications).

WARNING! Rotating blade can cause severe injury. Always disconnect the spark plug before performing any maintenance or blade changes.

Assembly & Setup

Unpack all components and inspect for shipping damage. Assembly requires basic tools.

1. Handle Attachment: Bolt the control handles to the main frame using provided hardware. Tighten securely.
2. Blade Installation: Ensure machine is off and spark plug disconnected. Place blade on spindle, secure with flange and nut. Tighten nut with provided wrench.
3. Water System: Fill the water tank with clean water. Connect hoses to pump outlet and blade guard inlet. Prime the pump if necessary.
4. Engine Preparation: Check engine oil level. Fill fuel tank with fresh, unleaded gasoline. Connect battery if electric start model.
5. Functional Check: Before starting, verify all controls move freely, blade guard is secure, and safety levers function correctly.

CAUTION! The saw is heavy. Use proper lifting techniques or a mechanical aid during assembly.

Operation

Starting, basic maneuvering, and shutdown procedures.

1. Pre-Start: Check water level, fuel, oil. Ensure area is clear. Set depth adjustment to zero.
2. Starting Engine: Open fuel valve. Set choke for cold start. Pull recoil starter firmly (or turn key). Allow engine to warm up.
3. Begin Cutting: Start water flow. Engage deadman switch and slowly lower blade into material using depth crank. Engage drive lever to move forward.
4. During Operation: Maintain a steady forward speed appropriate for material. Listen to engine load. Keep water flowing to blade.
5. Shutdown: Raise blade fully. Release drive lever. Release deadman switch. Turn engine off. Close fuel valve.

Tip: Make practice cuts on scrap material to get a feel for the machine's handling and cutting speed.

Cutting Procedures

Guidelines for different materials and cut types.

1. Concrete: Use a general-purpose or hard-bond diamond blade. Maintain consistent water feed. Watch for rebar.
2. Asphalt: Use a soft-bond blade. Water feed is still recommended to suppress dust and cool blade.
3. Straight Lines: Use a string line or chalk line as a guide. Use the front guide wheel to follow the line.
4. Deep Cuts: Make multiple passes, increasing depth incrementally (e.g., 2-3 inches per pass).
5. Curved Cuts: Possible with careful maneuvering. Make relief cuts for tight curves.

WARNING! Never cut without the proper blade guard in place. Avoid cutting near live electrical wires or gas lines.

Maintenance Schedule

Regular maintenance ensures long life and safe operation.

CAUTION! Always allow engine to cool before performing maintenance. Disconnect spark plug wire.

Storage

Proper storage prevents damage and corrosion.

1. Clean the saw thoroughly, removing all concrete slurry and debris.
2. Drain the water tank and pump. Run pump briefly with hoses disconnected to clear water.
3. For long-term storage: Either drain the fuel tank completely or add a fuel stabilizer and run the engine for 5 minutes to circulate it.
4. Store in a dry, covered location. Protect from extreme temperatures.
5. Remove the battery (if equipped) and store it charged in a cool, dry place.
