Avoid steering while travelling over steps. Travel
the machine perpendicular to the steps. Travelling
diagonally may result in the rubber tracks falling
off.

Rubber tracks can slip on wet steel plates, snow
and frozen surfaces. Operation in very cold
climates can shorten the life of the rubber tracks.
Operate with caution when travelling on slopes to
avoid track slippage.
Fig. 5-111
As much as possible, avoid operating the rubber
tracks on the following materials. Always wash the
tracks immediately and thoroughly with water after
use on the following materials.
• Material crushed and yielding oil, such as soy
beans, corns and rapeseed.
• Ammonium sulfate, potassium chloride or
concentrated super phosphate. These are
corrosive and will corrode the bonding of the
cored bar section.
Fig. 5-112
• Salt water and shore areas. Salt corrodes the
bonding of the cored bar section.
Only use the rubber tracks within the temperature
range of -25 to + 55°C.

When travelling over foods such as salt, sugar,
wheat and soybeans, pieces of wire or rubber may
become mixed in the food if the tracks are
damaged. Avoid travelling over foods or inspect
and repair as necessary before travelling over
foods.

Loose track tension will allow the rubber tracks to
fall off. Keep the track at the specified tension at
all times.
