Walk-Around Inspection

• Inspect speed control cable and return spring for smooth travel and intact seals
• Check mechanical service and parking brakes for function and engagement
• Verify all safety decals are intact and legible
• Inspect lug nut torque, tires, wheels, and tire pressure
• Ensure dump lever, directional control valve, and steering assembly operate correctly
• Check engine oil, hydraulic oil, and fuel levels; repair any visible leaks

Daily Maintenance

• Check engine oil and coolant levels
• Check hydraulic oil level with bucket down and oil cool
• Inspect all hydraulic hoses and fittings for leaks or damage
• Clean brake covers, reservoir louvers, dump levers, and operator platform
• Inspect speed control system and brakes for correct response
• Inspect tire pressure (inflate front and rear to 50 PSI)

Every 200 Hours or 6 Months

• Replace hydraulic oil and hydraulic oil filter
• Drain reservoir via hose connection and refill with SAE 10W-40 SE motor oil

Every 24 Months

• Replace speed control cable and return spring (or sooner under extreme use)

Brake Maintenance

• Inspect brakes daily under load—should stop within 6–8 feet and stall engine when pedal is pressed fully
• Tighten brake bands and adjust clevis if brake pedal travel is excessive
• Clean accumulated debris from brake area regularly
• Lubricate all brake pivot points after service or adjustment

Dump Lever & Speed Control Maintenance

• Adjust handle or console-mounted dump lever to ensure it returns to neutral easily
• Inspect and replace control cables if damaged or worn
• Verify spring return length and alignment for speed control system (target 4-15/16" spring length)

Hydraulic System

• Check and adjust dump valve pressure relief to 1500 ± 50 PSI
• Check directional valve pressure relief to 2000 ± 50 PSI

As-Needed Maintenance

• Clean machine daily to prevent concrete buildup
• Inspect and retorque lug nuts to 65 ft-lbs; retorque castle nuts to 125 ft-lbs using new cotter pins
• Use only approved cement dissolvers and avoid harsh acids
• Use Body Guard wax or similar to reduce concrete adhesion
