starter motor if used to prevent accidental startup. Meanwhile, place a tag of Do Not Operate in the operation room or
on the starting switch. Disconnect the cable from the post indicated by a NEGATIVE, NEG, or (–) first, then remove
the POSITIVE, POS, or (+) cable. When reconnecting the cables, connect the POSITIVE cable first, the NEGATIVE
cable last.
●Do not use a metal tool to contact the two battery posts, and do not make the two posts short circuit, or explosion
may happen.
●The connection of the battery cable posts must be secured. Explosion may happen due to poor connection.
Damaged wires or cables will cause fire. Check and replace them before reconnecting the wires and cables.
●Do not use fire, nor make welding near the battery(s) because battery can produce flammable hydrogen and oxygen.
Do not use the battery(s) when its electrolyte is lower than the minimum level. Improper use of electrolyte can cause
blind or scald.
●Keep a fire extinguisher near the engine at all times. Keep the extinguisher properly charged and be familiar with its
use. Keep an emergency medical box in a specified place where is accessible. Make sure there are measures
available for dealing with fire or accidents. Do not use any carbon fire extinguishers of tetrachloride type. These fire
extinguishers emit toxic fumes and the liquid can damage wiring insulation.
●Keep skin or eyes free from coolant or electrolyte when refilling and changing. In case of skin contact, please flush
the contacted part with soap and clean water; in case of eye(s) contact, flush your eye(s) for 15 minutes with clean
water and seek for medical treatment immediately.
●Cool down the engine first when refilling coolant to avoid being hurt by coolant steam. Open the pressure cap or filler
cap only when the coolant temperature is lower than 50℃, and then slowly loosen the cap to release the pressure of
coolant. The coolant is very hot when the engine has just stopped, and coolant steam or hot coolant can inject and
cause scald if the cap is opened. The cap must be tightened after checking, refilling or changing coolant.
●Do not touch by hand the intake and exhaust system components like the exhaust manifold, exhaust tailpipe,
turbocharger, intercooler air inlet pipe and expand tank when the engine is in operation because they are very hot.
The coolant is very hot when the engine is in operation, and steam or hot coolant will inject and cause scald if the cap
is opened.
●Stop the engine when the fan drive belt breaks, or the engine will go overheat, and coolant steam in the expansion
tank will inject and can cause scald.
●Do not handle discharged oil or replaced oil filter with bare hand, for high temperature oil or lubricating system part
are very hot and can cause scald.
●Release the pressure in the air, lubricating, cooling or fuel system prior to dismantling or loosening any of its
pipelines, permanent joints, connectors or relevant parts of the system. Otherwise high pressure fuel, lubricating oil
and coolant can cause personal injury.
●Make sure to shutdown the engine before any adjustment is performed to it and its driven equipment. Anything that
is caught in rotating parts can cause a serious accident..
●Use the barring tool. Do not rotate the engine with the fan, otherwise severe personal injury or damage to fan blades
can be caused.
●Take away the barring tool after being used, or it can damage the engine and cause personal injure when the engine
