Adjusting Belt Holder
Tips;
The ill-adjusted belt holder as well as wire may hinder the function
of the running clutch. After removing the belt holder to exchange
the V belt, adjust the belt holder as follows.
1. Let the platform dump.
2. Shift the running clutch lever to "running" position and adjust the
position of the belt holder so that the gaps on both sides between
the running V belt and the belt holder are 2-3 mm.(A figure 25)
3. Return the platform to its original position.
Tips:
The belt holder should occupy about one third of the engine pulley.
When the running clutch lever is in "stop" position, hold the belt a
bit to raise it slightly above the groove of the engine pulley.
Adjusting Tension of Crawler
The crawler tends to extend when it is brand-new, then loosened
as it sticks to the sprocket with time. As the ill-adjusted tension of
the crawler may let the wheels off the machine or significantly
shorten the crawler's life, adjust its tension as follows.
1. Raise the machine flatly against the ground with a jack.
Fix the jack tightly so as not to fall down during operation.
2. Loosen the lock nut on the crawler tension bolt at the
back.(A figure 26)
3. Turn the crawler tension bolt to adjust the gap A
between the crawler and the turning wheel to 8 mm.
(Figure 27)
4. After adjusting, fasten the lock nut tightly.
5. Lower the machine.
Safekeeping for a Long Time
Stop the engine. When draining the gasoline, choose a well-ventilated place and keep away
smoke or bare illumination. Be careful to handle the drained gas.
Store the machine in a solid level place.
When draining the gasoline in the tank or covering the machine, wait until the engine and muffler are
cooled down.
1. When not using the machine more than 30 days, drain the gas inside the carburetor and the fuel tank.
Otherwise, changed gas may cause trouble.
When draining the fuel in the tank, remove the fuel filter pot, attach the vessel as the receiver and
shift the fuel cock to "on (open)" position.
When draining the fuel in the carburetor, detach the fastening bolt at the underside.
2. Remove dirt and foreign substance at the machine and crawler.
When washing, protect electricity on the engine, carburetor, air cleaner and drain of muffler with covers
to avoid engine trouble.
3. Clean the engine and outside of the machine with an oiled clothe.
4. Exchange the engine oil.
5. Clean each parts sufficiently, especially the recoil starter, air cleaner, and muffler and carburetor.
Remove weeds or dust inside the belt cover with an air spray. Remove rust and put anti-rust paint.
If working without removing weeds or dust, they may choke the engine and cause a burn or a fire.
6. Lubricate each place and repair the machine if necessary.
