Routine and Scheduled Maintenance
Check and maintenance before working every day
To guarantee reliable work of puller, be sure to check following items before working, and eliminate off-normal phenomenon.
1. Whether fasteners in each connecting location get loose.
2. Whether cooling system of engine is filled up with water; whether water pipe connector has water leak.
3. Whether oil sump of engine is enough filled with engine oil according to engine oil scale label.
4. Whether fuel oil in the fuel tank is enough; whether each oil pipe joint has oil leak.
5. Whether accumulator is live; whether starting circuit joints of engine get loose; check lighting equipment.
6. Whether there is enough lubricating oil in speed reducer.
7. Whether hydraulic oil with code designation is enough in hydraulic reservoir; whether each oil pipe joint has oil leak.
8. Check whether each control handle is put in middle position.
9. Check whether the engine is prepared.
Check and maintenance after working everyday
1. Check fuel oil reserves, if fuel oil is short, it shall be filled.
2. Check whether oil pipe, water pipe and accessories are leaky
3. Check sealing and overheating of speed reducer, hydraulic oil pump and motor.
4. Check coupling bolts and pin shafts of engine, speed reducer, hydraulic oil pump, hydraulic motor, traction wheel, fan and pipe joint whether they get loose.
5. Welding seam of oil tank and vehicle frame is normal.
6. Let cooling water out when air temperature is below 0℃ (without filling anti freezing fluid)
7. Check tire pressure whether it’s enough, if the pressure is short, it shall be filled. Filling pressure is 800Kpa.
