HANDLE ROAD LINERS
Install to all the links of the right and left tracks always when installing the road liner. If it is installed partially
or to only one portion, its service life is shortened remarkably.
Precautions during operation
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 road liner.
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.
Avoid handling salt, ammonium sulfate, potassium chloride, potassium sulfate, and triple superphosphate or
wash the machine with water after the operation since they corrode the adhesive of the core metal.
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 road liners are used to handle salt, sugar, wheat, soybeans, etc., if it has a deep cut, rubber chips
may be mixed in the handled material. To prevent this, repair any cut before using.
Do not rub the road liner against concrete ridges, walls, etc. during operation.
The road liners are very slippery on wet steel plates, snow-covered or frozen road surfaces, or clay soil.
Beware of slipping and skidding when traveling or working on a slope.
If the road liners are used in an extremely cold district, their characteristics change and their service lives
are shortened accordingly.
Use the road liner in a temperature range from -25 to +65 °C.
Take care not to damage the road liner with the bucket during operation.
