Hangcha trolley water cooler, R series, RW21/22, K21 engine

In accordance with Regulation (EU) 2023/988 on general product safety (GPSR), the following rules set out the safe use of a forklift radiator.

Use and intended purpose

• The radiator is part of the engine cooling system and dissipates heat from the coolant.
• Use only on models approved by the manufacturer (dimensions, hose necks, fixing points, cap pressure rating).

Identification and compatibility

• Before installation, compare dimensions (length, height, thickness, core width), the position of outlets and brackets with the original part.
• Verify OEM/part number and permissible operating parameters according to the truck manufacturer’s documentation.

Main hazards

• High temperature and pressure: scalding risk; do not open the cap when hot.
• Chemicals: coolant can irritate skin and eyes and is harmful if swallowed.
• Moving parts: injury risk from fan/belt; carry out service with the engine off.
• Leaks and slip risk: clean up spills immediately; consider environmental impact.

Installation requirements

• Secure the truck, switch off the engine and allow it to cool; relieve system pressure.
• Use new gaskets, clamps and fasteners to specification; observe tightening torques.
• Route hoses clear of sharp edges and rotating parts; ensure fan clearance and guards.
• After installation, perform a pressure leak test and bleed the system.

Safe operation

• Use coolant to the manufacturer’s specification; do not mix types without checking compatibility.
• Regularly check coolant level, cap, clamps and hoses; fix leaks immediately.
• Keep the core and airflow paths clean; use moderate air/water pressure (do not bend fins).

Maintenance and inspections

• Replace coolant at the prescribed intervals; use demineralised water where specified.
• Monitor corrosion condition and operating temperature; diagnose deviations (thermostat, pump, fan, cap).

In case of leakage or overheating

• Do not open the cap when hot. Stop the truck, switch off the engine and allow to cool.
• Contain the spill and use absorbent material; clean contaminated surfaces according to safety rules.
• If the core or necks are damaged, suspend operation until repaired or replaced.

Storage and transport

• Store dry, in original packaging; protect fins from impacts and deformation.
• Do not place heavy objects on the core; protect necks from contamination.

Disposal

• Dispose of the used/damaged radiator via authorised metal/electromechanical recycling in line with local rules.
• Treat coolant as hazardous waste; never pour into drains or the environment.
• Recycle packaging after cleaning.

Additional information

• Installation and repair must be carried out by qualified personnel using PPE (gloves, goggles).
• Follow the truck manufacturer’s documentation for torque values, cap pressure and bleeding procedure.
