Set-up & operation (quick guidance)
- Mount securely: Fix the unit on a firm base or trolley; isolate vibration where possible.
- Fuel & oil: Fill fresh petrol; check engine oil level before each run.
- Suction line: Use a clean strainer and airtight hose runs; prime the line to protect the pump.
- Nozzle selection: Match tip size and pattern to your target (foliar, trunk, under-leaf). Test pattern before entering the block.
- Operate smoothly: Bring RPM up gradually; maintain steady pressure for uniform droplet size.
- End of day: Flush with clean water; depressurize lines; check filters and fittings for wear.
Typical applications
- Agriculture: Spraying pesticides, herbicides, and foliar fertilizers.
- Horticulture: Orchards, vineyards, nurseries, and greenhouses.
- Commercial: Large-area spraying for landscapes and estate maintenance.
Helpful ownership tips
- Carry spare plug, fuel filter, and nozzle washers; downtime costs more than parts.
- Keep suction height low and hoses short to minimize cavitation and pressure loss.
- Store with stabilized fuel if idle for extended periods; run the engine briefly each month.
