system pressure to the system set value and then release the pressure and drain the oil back to the
hydraulic oil tank) to heat the hydraulic oil, which can ensure good response of the machine and
prevent malfunction.
1.5.22.3 When the battery electrolyte has been frozen, do not charge the battery or start the engine
with other power supply, which is very dangerous, and may cause the battery to fire. Before charging
the battery or starting the engine with other power supply, melt the battery electrolyte and check for
leakage.
1.5.22.4 After the operation, clear all the water, snow and mud sticking to the wire, wire connector,
switch, sensor and the covering parts of these parts, otherwise, the water will get frozen, which may
cause failure of machine parts next time the machine is used.

Safety in operation and overhaul of components
★
Radiator:
1.5.23.1 Depending on the different regional environments, antifreeze fluid in different proportions
should be added to the coolant;
1.5.23.2 Clean softened water should be used for the radiator. No corrosive fluid should be added to
the radiator. No entrained mud or sand, etc;
1.5.23.3 When opening hot radiator cap, loosen it slowly to allow steam to escape, and remove the
cap;
1.5.23.4 When the engine is overheating, don’t fill the radiator with low temperature coolant to prevent
engine cylinder head and jacket pipe from cracking due to temperature jump;
1.5.23.5 For the cooler with an expansion chamber, in the process of filling, the coolant from the refill
pipe of the upper chamber continuously flows through the radiator outlet to the expansion chamber. It
takes a long time to fully fill the cooler, and don’t start the engine until the filling is finished;
1.5.23.6 For the cooler with an expansion chamber, leave appropriate space in the upper part of the
chamber when filling it, and don’t over-fill it.
★
High temperature components and fluid after operation:
1.5.23.7 The engine, radiator, and transmission parts may be hot. During operation or immediately
after shutdown, do not touch high temperature components. If you have to, take enough safety
protective measures, i.e. wear protective goggles and high temperature resistant gloves;
1.5.23.7 It is prohibited to service high temperature components during machine operation to prevent
high temperature fluid from splashing to damage people;
1.5.23.8 The temperature of the added fluid can be at most 10
℃
lower than that of the high
temperature components to prevent machine material from cracking due to sudden cold;
★
Brake:
1.5.23.9 The brake is an important safety component of the machine. After startup and before
operation, always test brake performance for correct operation of the braking device;
1.5.23.10
During operation, in case of no special need, do not hold your foot on the brake pedal or
