good ventilation when handling fuel.
Fuel (Fig. 20)
○
Always use branded 89 octane unleaded gasoline.
○
Use genuine two-cycle oil or use a mix between 25:1 to
50:1, please consult about the oil mixture ratio to Tanaka
dealer.
○
If genuine oil is not available, use an anti-oxidant added
quality oil expressly labeled for air-cooled 2-cycle engine
use (JASO FC GRADE OIL or ISO EGC GRADE). Do not
use BIA or TCW (2-stroke water-cooling type) mixed oil.
○
Never use multi-grade oil (10 W/30) or waste oil.
○
Never mix fuel and oil in machine’s fuel tank. Always mix
fuel and oil in a separate clean container.

Starting the cold engine (Fig. 22-27)
CAUTION
Before starting, make sure that the cut-o ff wheel does
not touch anything.
1. Set stop switch (21) to ON position. ( Fig. 22 )
2. Pull choke lever (22) fully to set it in the START position.
( Fig. 23 )
3. Push the priming pump (23) approximately ten times so
that fuel fl ows into carburetor. ( Fig. 24 )
