4. Checking the tire pressure
WARNING
To avoid serious injury or death:
• Do not attempt to mount a tire on a rim. This
should be done by a qualified person with the
proper equipment.
• Always maintain the correct tire pressure.
The inflation pressure in the front tires rises
quickly when using compressed air.
Do not inflate the tires above the recommended
pressure shown in the operator's manual.
IMPORTANT :
• Do not use tires larger than specified.
4.1 Inflation pressure
Even though the inflation pressure is factory-set to the
prescribed level, it naturally drops slowly in the course
of time. Therefore, check it everyday and inflate as
necessary.

5. Checking movable parts
If any of the movable parts, such as levers and pedals,
cannot be smoothly moved because of rust or anything
sticky, do not attempt to force it into motion.
In this case, remove the rust or the sticky object, and
apply oil or grease on the relevant spot. Otherwise, the
machine may get damaged.
EVERY 50 HOURS
