• If the rubber parts of the road liner are worn and damaged and the mounting bolt heads are damaged, re-
place the shoes with new ones immediately.
If the mounting bolt heads are crushed, they cannot be removed or installed anymore.
• When installing the road liner, always install to all the links of the right and left tracks.
If it is installed partially or to only one portion, its service life is shortened remarkably.
PRECAUTIONS FOR USING RUBBER AND ROAD LINERS SHOES
When operating, observe the following.
• Do not make a pivot turn on a concrete road since rubber marks are made on the road surface.
• Avoid turning sharply whenever possible, since that can cause early wear and chipping of the rubber shoes
and road liners.
• Avoid turning on a large level difference.
When riding over a level difference, travel perpendicularly to it to prevent the shoes from coming off.
• Once you raise the machine by using the work equipment, lower it slowly.
• Avoid handling crushed and oily material (cakes of soybean, corn, rapeseed, etc.) or wash the machine with
water after the work.
• Do not use the rubber shoes and road liners on seashore since the adhesive of the core metal is corroded
by the salt.
• When the rubber shoes and road liners are used to handle salt, sugar, wheat, soybeans, etc., if they have a
deep cut, rubber chips may be mixed in the handled material. To prevent this, repair any cut before using.
• Do not rub the rubber shoes and road liners against concrete ridges, walls, etc. during operation.
• The rubber shoes and road liners are very slippery on wet steel plates, snow-covered or frozen road surfa-
ces.
Beware of slip when traveling on a face of slope or operating on a slope.
• If the rubber shoes and road liners are used in an extremely cold district, their material quality change and
their service life are shortened accordingly.
• Use the rubber shoes in a range from -25 to 55 °C due to the properties of rubber.
Use the road liners in a range from -25 to 65 °C.
• Take care not to damage the rubber shoes and road liners with the bucket during operation.
• Keep the rubber shoe tension proper to prevent the rubber shoes from coming off the rollers.
When the rubber shoes tension is loose in the following conditions, the rubber shoes may sag and come
off.
Even if the rubber shoes tension is correct, the rubber shoes may sag in such conditions, be extremely
careful when steering the machine.
1.
Do not steer the machine on curb stones or rocks
where there are level differences (approximately
20 cm or more).
When riding over a level difference, drive at right an-
gles to it.
