ISUZU fire fighting trucks are specifically designed and equipped to support firefighting and rescue operations. During use, factors such as friction, vibration, impact, and environmental conditions inevitably lead to loosening, deformation, wear, or corrosion of components. With increasing mileage, the overall condition of the vehicle tends to deteriorate, potentially resulting in reduced power, efficiency, and safety, and in some cases, mechanical failure or accidents. Therefore, consistent and thorough maintenance is crucial to ensuring operational readiness and extending service life.
The equipment compartment storing basic firefighting and rescue tools requires regular attention, although it is often neglected. To protect stored items, use rubber or soft padding to prevent friction damage. Regularly check the compartment for water, ensure mounting brackets are secure, confirm that roller shutters operate smoothly, and check for deformation or damage. Lubrication points such as door guide rails should also be lubricated as needed.
As the core of the fire protection system, the fire pump requires meticulous maintenance. All rotating parts should be lubricated every 3 to 6 hours of operation. Regularly test key performance indicators such as maximum suction depth, start-up time, and flow rate—significant deviations from standard values should be investigated immediately. After using contaminated water or foaming agents, thoroughly flush the pump, water tank, and piping system. Always keep the water ring pump housing, wiper reservoir, water tank, and foam tank fully filled. Regularly clean and lubricate the monitor rotating base, check the oil levels in the pump and gearbox, and replace or refill if the oil is milky or insufficient.
Water tanks or foam tanks are typically kept full of reagents and are prone to corrosion over time, especially on older vehicles or foam trucks. If left untreated, rust can seep into the tank, and residue can enter the pump, damaging the impeller and affecting operation. Regular internal inspections are crucial; if corrosion is found, clean and dry the affected areas before applying an epoxy coating or performing weld repairs. Connected valves and pipes should also be inspected and cleaned regularly.
The general condition of the vehicle must be systematically assessed. Key areas include: loose or missing bolts and lubrication requirements in the drivetrain (clutch, transmission, driveshaft, differential, etc.); brake system (pedal feel, air compressor, air tank, valves, and brake pad wear); steering response; and the operating condition of lights, wipers, and warning lights. Address any malfunctions promptly—repair or adjust components as needed, and ensure proper tightening and lubrication.
The power take-off (PTO) and pump drive shaft are critical for pumping operations. Regularly verify that the PTO engages and disengages smoothly without unusual noises or automatic disengagement. Check the drive shaft for unusual sounds, loose fasteners, or insufficient lubrication; lubricate bearings and joints as necessary.
Electrical systems and instrumentation also require careful maintenance. Always use appropriately rated fuses to avoid damaging components. Regularly test warning lights, alarms, compartment lights, pump room lights, solenoid valves, level indicators, tachometers, and all switches and gauges, immediately troubleshooting any faults to ensure full operational capability in emergency situations.
