12. Inspection/Maintenance 

 

Warning: Electric Shock/Injury 

 

Always be sure to stop the engine and remove the engine key before performing 
any equipment check or maintenance. 

 

Do not operate the equipment with any doors or covers open. There is a danger of 
hair, body parts and other items being caught up in moving parts such as cooling 
fans and belts. 

 

Do not modify the equipment and do not operate with parts removed. 

Warning: Fire 

 

Always be sure to stop the engine when inspecting fuel or refueling, and absolutely 
never perform such tasks near fire or other open flame. Wait until the engine has 
completely cooled before inspecting fuel or refueling. 

 

Always be sure to wipe up any spilled fuel or oil. 

 

Spilled fuel and oil accumulates in the spill containment. Do not operate the 
equipment with liquid accumulated in the spill containment. 

 

Absolutely never use the equipment if there is a fuel, oil or cooling water leak, and 
be sure to always repair the leak before using. 

 

Absolutely never inspect or perform maintenance to the equipment near fire or other 
open flame. 

Warning: Injury to Eyes and Skin 

 

Use protective gear, such as rubber gloves, when inspecting or replacing the battery 
due to the dilute sulfuric acid in the battery fluid. Be sure that fluid does not get into 
eyes, or on skin or clothing. 

 

If battery fluid gets into the eyes, or on the skin or clothing, immediately wash with a 
large amount of water, and always be especially sure to seek medical attention if it 
gets into the eyes. 

Warning: Explosion 

 

Do not operate the equipment or recharge the battery when the battery fluid level is 
below the minimum level. 

 

Do not generate any sparks near the battery and do not allow any fire or other open 
flame near the equipment because the battery generates ignitable gas. 

 

Caution: Burn 

 

The engine, muffler and similar parts are extremely hot during operation and 
immediately after stopping the equipment. Never touch hot parts. 

 

Never open the radiator cap during operation or immediately after stopping the 
equipment. Hot cooling water and steam will spurt out. 

 

Always be sure to stop the engine and allow it to cool before inspecting or changing 
the engine oil. Opening the oil gauge or oil plug during operation will result in hot oil 
spurting out. 

 
<Note> 

 

Procedures except for pre-operation inspection must be performed by specialized 
technicians. 

 

Items indicated by 

: Contact the retail outlet where the equipment was purchased. 

 

Always be sure to use genuine parts when replacing parts. 

 

When removing waste liquid from the equipment, place some container to collect the 
liquid and prevent it from spilling on the ground. Dispose of such oil, fuel, cooling 
water (LLC), filters, batteries and other harmful substances as industrial waste in 
accordance with applicable laws and regulations. Consult with the retail outlet where 
the equipment was purchased if you have any inquiries regarding proper disposal. 

 

When performing maintenance with doors or covers open, be sure that no other 
persons can accidentally come close to the equipment. Close all doors and covers if 
momentarily leaving the equipment unattended.
