Fuel and lubricant

Whenever opening up the fuel tank, always loosen the cap very slowly and wait for
the tank pressure to be equalized before removing the cap.
Fuel is a mixture of regular grade petrol and an air-cooled 2-stroke engine oil.
Minimum 89 Octane unleaded petrol is recommended.
Do not use fuel containing methyl alcohol or more than 10 % of ethyl alcohol.
Recommended mixture ratio; 50 : 1 (2 %) for ISO-L-EGD Standard (ISO/CD13738),
JASO FC, FD grade and shindaiwa recommended oil.
- Never use two-stroke oil intended for water-cooled engines, motor-cycle engines.
- Do not mix directly in engine fuel tank.
- Avoid spilling petrol or oil.
Spilled fuel should always be wiped up.
- Handle petrol with care, it is highly inflammable.
- Always store fuel in approved container.

Chain lubricant

Proper lubrication of the chain while in operation minimizes friction between the chain,
the guide bar and sprocket and also clutch components such as needle bearing and
clutch assembly.
Use shindaiwa genuine chain oil or shindaiwa recommended chain oil specially
formulated for bars and chains for proper lubrication.
These oils contain tackifiers, anti-aging and anti-oxidizing agents.
Consult your shindaiwa dealer for the proper chain oil.
Never use waste or reclaimed oil to avoid various malfunctions on oil system, clutch
system, chain and guide bar.
Lubrication problems caused by the use of improper oil will void the warranty.
Especially, vegetable based chain oil quickly turns to resin and adheres to oil pump,
chain, guide bar, clutch needle bearing and clutch assembly.
It causes malfunctions and shorten product life.
Flush chain oil system with mineral or chemical based chain oil after use, if it is required to
use vegetable oil due to local / municipal rule or any other reason.
For a short time emergency operation, fresh SAE 10W-30 motor oil can be used.
