A FEW WORDS ABOUT SAFETY 

SERVICE INFORMATION

The service and repair information contained in this manual is intended for use by qualified, professional technicians.
Attempting service or repairs without the proper training, tools, and equipment could cause injury to you or others. It could also 
damage the vehicle or create an unsafe condition.
This manual describes the proper methods and procedures for performing service, maintenance, and repairs. Some procedures 
require the use of specially designed tools and dedicated equipment. Any person who intends to use a replacement part, service 
procedure or a tool that is not recommended by Hero MotoCorp, must determine the risks to their personal safety and the safe 
operation of the vehicle.
If you need to replace a part, use genuine Hero MotoCorp parts with the correct part number or an equivalent part. We strongly 
recommend that you do not use replacement part of inferior quality.

FOR YOUR CUSTOMER’S SAFETY

Proper service and maintenance are essential to the customer’s safety and   the 
reliability of the vehicle. Any error or oversight while servicing a vehicle can result in 
faulty operation, damage to the vehicle, or injury to others.

FOR YOUR SAFETY

Because this manual is intended for the professional service technician, we do not 
provide warnings about many basic shop safety practices (e.g., Hot parts- wear 
gloves). Some of the most important general service safety precautions are given 
below. However, we cannot warn you of every conceivable hazard that can arise in 
performing service and repair procedures. Only you can decide whether or not you 
should perform a given task.

IMPORTANT SAFETY PRECAUTION

Make sure you have a clear understanding of all basic shop safety practices and 
that  you  are  wearing  appropriate  clothing  and  using  safety  equipment.  When 
performing any service task, be  especially careful of the following:
•  Read all of the instructions before you begin and make sure you have the tools, 

  the replacement or repair parts and the skills required to perform the tasks safely and completely.

•  Protect your eyes by using proper safety glasses, goggles or face shields any time you hammer, drill, grind, pry or work around 

  pressurized air or liquids, and springs or other stored- energy components. If there is any doubt, put on eye protection.

•  Use other protective wear when necessary, for example gloves or safety shoes. Handling hot or sharp parts can cause severe 

  burns or cuts. Before you grab something that looks like it can hurt you, stop and put on gloves.

•  Protect yourself and others whenever you have the vehicle up in the air. Any time you lift the vehicle, either with a hoist or a jack, 

  make sure that it is always securely supported. Use jack stands.

Make sure the engine is off before you begin any servicing procedures, unless the instruction tells you to do otherwise.
This will help eliminate several potential hazards:
•  Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you run the engine.
•  Burns from hot parts. Let the engine and exhaust system cool before working in those areas.
•  Injury from moving parts. If the instruction tells you to run the engine, be sure your hands, fingers and clothing are out of the 

  way.

Gasoline vapors and hydrogen gases from batteries are explosive. To reduce the possibility of a fire of explosion, be careful when 
working around gasoline or batteries.
•  Use only a nonflammable solvent, not gasoline, to clean parts.
•  Never drain or store gasoline in an open container.
•  Keep all cigarettes, sparks and flames away from the battery and all fuel- related parts.

Improper service or repairs can create an 
unsafe  condition  that  can  cause  your 
customer or others to be seriously hurt or 
killed.  Follow  the  procedures  and 
precautions  in  this  manual  and  other 
service materials carefully.

Failure to properly follow instructions and 
precautions can cause you to be seriously 
hurt or killed.
Follow the procedures and precautions in 
this manual carefully.
