Maintenance Schedule

Regular maintenance is essential for reliable operation. Follow this schedule based on operating hours.

Interval (Hours)	Service Task
Daily (Before use)	Check engine oil level, fuel level, hydraulic oil level, blade condition & tightness, track tension, water system function.
50 Hours	Change engine oil and filter. Clean air filter element. Check and clean fuel filter. Inspect spark plug (if equipped).
100 Hours	Change hydraulic oil filter. Check drive track wear and alignment. Inspect all hoses and connections for leaks.
250 Hours	Change hydraulic oil. Clean fuel tank. Inspect and adjust valve clearance (engine). Check water pump seals.
500 Hours	Replace air filter. Replace fuel filter. Inspect and repack wheel bearings. Comprehensive inspection of all systems.

Engine Service

Procedures for maintaining the diesel engine.

Oil Change: Run engine to warm oil. Drain via plug. Refill with recommended SAE XX oil to correct level.
Air Filter: Remove cover, clean primary element, replace safety element as needed. Never run engine without filter.
Fuel System: Drain sediment from water separator daily. Replace fuel filter cartridge.
Cooling System: Keep cooling fins clean. Ensure air intake and exhaust are unobstructed.
Valve Adjustment: Perform on cold engine. Set intake to X.X mm, exhaust to X.X mm.

CAUTION! Use only genuine Husqvarna or recommended parts and fluids.

Cutting System & Blade Assembly

Instructions for blade installation, removal, and spindle maintenance.

Blade Installation: Ensure machine is off and blade lock is engaged. Remove flange nut using correct tool. Mount blade with correct rotation arrow facing forward. Tighten nut to specified torque (XXX Nm).
Spindle Bearing Check: Check for play or roughness by rocking blade. Replace bearings if excessive play or noise is present.
Blade Guard: Inspect for damage. Ensure it moves freely and returns to cover blade adequately.
Depth Adjustment: Check gear mechanism. Lubricate threads periodically.

WARNING! Always use blades rated for the machine's maximum RPM. Inspect for cracks or damage before each use.

Hydraulic System

Maintenance of the track drive and blade drive hydraulic systems.

Oil Type: Use recommended hydraulic oil ISO VG XX.
Filter Change: Turn off engine. Relieve pressure. Replace spin-on filter element.
Checking for Leaks: Inspect all hoses, fittings, and cylinders. Tighten connections or replace components as needed.
Track Drive Motor: Check for oil leaks at motor seals. Ensure drive sprockets are securely fastened.
System Bleeding: After oil change or component replacement, run engine at idle, operate controls slowly to purge air from system.

Electrical System

Service information for starting, charging, and control circuits.

Component	Test/Service Procedure
Battery	Check terminals for corrosion. Maintain fluid level (if applicable). Test voltage (>12.4V).
Starter Motor	Check connections. Listen for engagement. Bench test if engine does not crank.
Alternator	Check belt tension. Test output voltage (XX-XX V @ idle).
Wiring Harness	Inspect for frayed wires, loose connectors, or damage from heat/vibration.
Switches & Sensors	Test continuity. Replace faulty switches (e.g., safety interlocks, throttle position).

Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
Engine will not start	Empty fuel tank, clogged fuel filter, weak battery, faulty glow plugs (if cold)	Refuel, replace filter, charge/replace battery, check glow plug circuit.
Engine lacks power	Dirty air filter, clogged fuel filter, incorrect throttle linkage adjustment	Clean/replace air filter, replace fuel filter, adjust linkage.
Blade does not turn	Hydraulic oil low, drive belt broken, hydraulic pump failure, engagement lever cable broken	Check oil level, inspect/replace belt, check pump pressure, adjust/replace cable.
Tracks do not move or move unevenly	Low hydraulic oil, track tension incorrect, drive motor failure, control valve issue	Check oil, adjust tension per manual, test motor output, inspect valve.
Excessive vibration	Worn or damaged blade, loose blade flange, worn spindle bearings, unbalanced blade	Inspect and replace blade, tighten flange, replace bearings, balance blade.
Hydraulic oil overheating	Oil level low, oil cooler blocked, incorrect oil viscosity, pump internal wear	Top up oil, clean cooler fins, use correct oil, test pump efficiency.
