Tightening Torques

Important

Refer to the Tightening Torque table.Note that the Baroness product warranty maynot apply to defects caused by incorrect orovertorque tightening, etc.

Standard Tightening TorquesBolts and Nuts

Important

A number of bolts are used in each part of this machine.Be sure to re-tighten the bolts and nuts, because they may be loosened at the earlier stage of theuse.

As to the bolts and nuts without any special instruction, tighten them in appropriate tightening torquewith proper tool.Too much tightening may cause the looseness or damage of the screw.The strength of tightening is determined by types of screws, strength, the friction of thread face orbase face and others.The table below is for the galvanized or parkerized bolts.In case that the strength of internal thread is weak, it is not applied.Do not use rusty or sand attached "screw."Otherwise, it may cause insufficient tightening even if you apply the specified tightening torque.The friction of the screw face becomes higher and the tightening torque is canceled out by thefriction, therefore sufficient tightening cannot be applied.If "screw" is wet by water or oil, do not tighten it with normal tightening torque.If the screw is wet, the torque coefficient will get smaller and it may result in too much tightening.Too much tightening may cause looseness by the screw stretched or result in damage.Do not use a bolt experienced too much burden.Using the impact wrench requires the skill.Do exercise as much as possible for steady tightening.

Change of Coolant

Caution

Do not touch the radiator or coolant duringengine operation or immediately after theengine has been turned off.Otherwise, you may get burned due to hightemperatures.

Caution

Change coolant after the engine has wellcooled down.

Caution

The radiator cap is pressurized.If you remove the radiator cap while theengine is overheated, hot steam will burst out,possibly resulting in burns.Make sure that the water temperature andpressure are reduced, and then grab the capwith a thick cloth and gradually open the cap.

Important

When changing the coolant, be sure to drain itinto a container and discard it in accordancewith local laws and regulations.

Important

When changing the coolant, be sure to mixclean water (soft water) and antifreeze (long-life coolant), and then pour it into the radiatorand reserve tank.

Important

Tightly close the radiator cap.If the cap is loose or incorrectly installed,water may leak and the engine may overheat.

When mixing antifreeze and clean water (softwater), refer to "Relationship betweenconcentration of long-life coolant (LLC) andfreezing temperature" below for the mixingratio.Relationship between concentration of long-lifecoolant (LLC) and freezing temperature
