[4] TIRE LIQUID INJECTION
Auxiliary weights can be used to increase traction force for plowing in fields or clayey ground.
Another way is to inject water or another liquid, such as a calcium chloride solution in the tires. Water must not be
used in winter since it freezes at 0 °C (32 °F). The calcium chloride solution will not freeze and moreover, affords
higher effect than water since its specific gravity is higher than that of water by about 20 %. Below is an explanation
of calcium chloride solution injection.
IMPORTANT
Q
• Do not fill the front tires with liquid.
Preparation of Calcium Chloride Solution
CAUTION
• When making a calcium chloride solution, do not pour water
over calcium chloride since this results in chemical reaction
which will cause high temperature. Instead add a small
amount of calcium chloride to the water at a time until the
desired solution is achieved.

Attaching Injector
1. Lift the rear tires off the ground.
2. Turn the tire so that the air valve is at the top.
3. Remove the air valve, and attach the injector. (Code No. 07916-
