Operating Instructions

Starting Procedure:

Pre-Operation Check: Verify oil, fuel, water. Ensure blade is secure and area is safe.
Set Choke: Move choke to "ON" for cold starts.
Ignition: Turn key to "ON". Press electric start button or pull recoil starter.
Warm Up: Allow engine to run at idle for 1-2 minutes. Move choke to "OFF".
Engage Water: Turn water pump switch to "ON" to start coolant flow to blade.
Begin Cut: Slowly lower blade to desired depth using adjustment wheel. Apply forward pressure evenly.

Tip: Make practice cuts on scrap material to familiarize yourself with machine handling.

Cutting Procedures

For concrete, asphalt, and masonry.

Mark Cut Line: Use chalk line for straight cuts.
Set Depth: Adjust depth wheel. Do not exceed max depth in one pass for deep cuts; make multiple passes.
Position Saw: Align guide wheels with cut line.
Start Engine & Water: Begin coolant flow before blade contacts material.
Make Cut: Apply steady forward pressure. Let blade do the work; do not force.
Curved Cuts: For curves, reduce speed and use light steering pressure on handle.
End of Cut: Release throttle, raise blade completely out of cut, turn off water pump, then engine.

WARNING! Never cut without water cooling (for dust control and blade life). Avoid sudden movements. Watch for kickback.

Maintenance Schedule

Regular maintenance ensures performance and longevity.

Interval	Task
Daily (Before Use)	Check blade condition, fuel/water levels, oil level, tire pressure, all fasteners.
Every 25 Hours	Clean air filter. Check spark plug.
Every 50 Hours	Change engine oil. Inspect water pump and hoses.
Every 100 Hours	Replace air filter. Check valve clearance (refer to engine manual).
As Needed	Replace worn blade. Grease guide wheel bearings. Check drive belt tension.

CAUTION! Perform maintenance only when machine is off and cool. Use genuine Husqvarna parts.

Storage & Transport

For long-term storage, run engine to use up fuel in carburetor or add fuel stabilizer. Drain water tank and lines to prevent freezing. Store in a dry, covered area. For transport, secure saw in vehicle using straps. Ensure blade guard is installed.

CAUTION! Always transport with blade guard on. Secure machine to prevent movement.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Engine will not start	No fuel, choke not set, spark plug faulty, switch off	Check fuel level; set choke correctly; inspect/clean spark plug; ensure ignition is on.
Loss of power during cut	Dull blade, too deep cut, low throttle	Replace blade; reduce cutting depth per pass; increase throttle.
Excessive vibration	Damaged/worn blade, loose components	Inspect blade for damage; tighten all bolts and blade nut.
Water not flowing	Empty tank, clogged hose/nipple, pump failure	Fill tank; clear hose and water nipple; check pump operation.
Cut not straight	Misaligned guide wheels, uneven pressure	Adjust guide wheel alignment; apply even forward pressure.
Blade overheating	Insufficient water, wrong blade type, forced cut	Ensure adequate water flow; use correct blade for material; do not force saw.
