Operating a HOWO dump truck requires specific knowledge and skills to ensure safe and efficient operation. This comprehensive guide covers the essential aspects of driving and operating HOWO dump trucks, from pre-operation checks to dumping procedures.
Before starting the engine, conduct a thorough pre-operation inspection. Check engine oil level, coolant level, hydraulic oil level, tire pressure and condition, lighting systems, and brake system functionality. Verify that all mirrors are properly adjusted and that the cab is clean and free of obstructions.
Starting the HOWO dump truck involves turning the ignition key to the ON position and waiting for the glow plug indicator to extinguish (for diesel engines). With the transmission in neutral and the parking brake engaged, start the engine and allow it to idle for 3-5 minutes to achieve proper operating temperature and oil circulation.
Driving the HOWO dump truck requires familiarity with the HW19710 10-speed manual transmission. The gear shift pattern is standard H-pattern with a range selector for high and low ranges. Start in low range first gear for loaded conditions, shifting through the gears as speed increases. The engine's optimal operating RPM range is typically 1,200-1,800 RPM for fuel efficiency and power delivery.
The dumping procedure requires careful attention to safety. Position the vehicle on level, stable ground. Engage the parking brake and ensure the transmission is in neutral. Activate the Power Take-Off (PTO) to engage the hydraulic pump. Slowly raise the dump body using the hydraulic control lever, monitoring the load distribution and stability. Never operate the dump body while the vehicle is moving or on uneven terrain.
The engine number is typically located on the engine block, near the fuel injection pump or on the timing cover. On WD615 and WP10 engines, the engine number is stamped on a flat surface on the left side of the engine block. This number is essential for parts ordering, warranty claims, and vehicle registration documentation.
