Maintenance
Oil maintenance of the internal assembly
When replacing the oil, be careful that no oil gets on the disc brake rotor, pads, on the rim when using
rim brakes, etc. If oil gets on any of these parts, there is a danger that brake performance may be
reduced. Take care of this problem according to the procedures in the brake instruction manual.
Since there is a risk of explosion or fire, do not smoke, eat, or drink while using this oil. In addition,
keep it away from ignition sources such as heat, sparks, open flames, or high temperatures and prevent
it from catching fire due to static electricity sparks or other sparks.
Use only outdoors or in a well-ventilated area. Inhalation of oil mist or vapors may cause nausea. Be
careful to provide ventilation and use a respirator type mask. If mist or vapor is inhaled, go immediately
to an area with fresh air. Cover up with a blanket. Stay warm and stable and seek professional medical
advice.
Cautions regarding handling of SG-S700 OIL
Use appropriate eye protection when handling, and avoid contact with eyes. In the event of eye
contact, flush with fresh water and seek medical assistance immediately. Contact with eyes may result
in irritation.
Use gloves when handling. In the event of skin contact, wash well with soapy water. Contact with skin
may cause a rash and discomfort.
Do not drink. If it is drunk by mistake, do not induce vomiting; make the affected person drink 1 to 2
cups of water and seek medical assistance immediately. If the affected person loses consciousness, do
not give the person anything by their mouth. If vomiting occurs naturally, tilt the body to prevent
inhalation.
After use, be sure to wash hands thoroughly.
Keep the container sealed to prevent foreign objects and moisture from getting inside, and store it in a
cool, dark area away from direct sunlight.
Keep out of reach of children.
Dispose of used oil, old oil, or oil used for cleaning in accordance with the method stipulated by the
law.
In order to maintain proper performance, it is recommended that you replace the oil after riding 1,000
km from the start of use, then after about once every year (or once about every 2,000 km if the bicycle
is used very frequently).
Do not use oil other than SG-S700 OIL. Problems such as an oil leakage and gear shifting malfunction
may occur.
Disposal of used oil: Follow local county and/or state codes for disposal. Use caution when preparing
