(3) Running the starting device by plenty battery, meter the pressure at this time.
(4) Measure the other 5 cylinder by the same way, and measure 2 times, then
figure out each average value; compression pressure: 304N/cm

1.6.11 Exhaust of injection pump ( Fig 1.20)
(1) Loosen core vent of injection pump.
(2) Operate hand pump slowly till the core vent doesn't bubbling.
(3) Tighten the core vent.

1.7 Precautions of cooling system
(1) During using the forklift truck, if the temperature of the radiator or coolant is too
high, don’t open the cap of the radiator immediately. To find the reason for boiling, use
extreme care when removing the cap, the sudden release of pressure can cause a
steam flash which would cause a serious personal injury. Lower the running speed of
the engine to moderate speed, after the cooling system cooled then turn to idle speed,
loosen cap slowly to allow steam to escape, the cap can be removed. After that, make
sure the cap is tightened securely.
(2) Check the radiator coolant reservoir fluid level. It should between FULL and
LOW mark. Add the same type coolant to specified level if necessary. The coolant can
be used all the year round.
(3) Put the coolant on a safe place and mark “Dangerous Matter” for its toxicity. If
swallowed by accident, take the emergency first aid and consult a physician
immediately.
(4) According to variety working condition, periodic wiping away the dirt adhering to
the surface of the radiator with detergent, compressed air or high pressure water
(pressure less than 4kg/cm
2
) is necessary.
