PRECAUTIONS FOR SAFETY AND QUALITY

PRECAUTIONS FOR SAFETY AND QUALITY
The following precautions must be carefully observed for safe
and appropriate service work.
Only qualified and designated personnel must perform
inspections, repairs and adjustments.
Always keep the workplace clean, and store tools neatly in
specified places.

Safe Operation

Do not run engines inside the workshop without proper
ventilation (ex. no ventilation ducts).
Keep the workshop well ventilated and free of any flammable
materials. Special care should be taken when flammable or
poisonous materials such as gasoline are handled.
Discard waste oil after oil changes or parts treatment in
accordance with local laws and regulations.
Be careful of burns and injury when working on high-
temperature parts, rotating parts, or sliding portions.
When working in a pit or enclosed area, ensure that adequate
ventilation is provided for discharging any hazardous emissions.
GIM0057
Do not work underneath a vehicle supported only by a jack.
Always use rectangular wood blocks at the prescribed points to
support the vehicle.
Support it at the prescribed points and lock it in position with
safety devices before lifting the vehicle.
When removing a heavy component such as the engine and
vehicle side, be careful the vehicle body does not become off-
balance and fall.
Do not smoke during service work.
Do not wear any rings and necklaces when working. These
GIM0058
objects may cause electric short.
Before starting repair work that requires no battery power,
always turn OFF the ignition switch, and disconnect the
negative battery cable.
GIM0059
Do not touch any metal portions immediately after the engine is
stopped. Otherwise the heated metals may cause burns. Do not
attempt to remove any cooling system parts such as the radiator
cap while the engine is hot.
To perform repair work safely and efficiently, always use
appropriate commercial service tools and specified STs
wherever required.
