NOTICE
Risk of environmental pollution!
The grease in the track adjustment cylinder is under
high pressure and large quantities of grease will be
quickly released if the valve is loosened too much.
Never loosen the valve by more than two turns
when draining the grease.
8 To enlarge the track slack on both rubber and
steel tracks, loosen the valve assembly (2)
through one turn so the grease can drain off.
Tighten the valve unit when the track slack is
correct.
9 Adjust the other track unit in the same way.
10 Run the track several times in forward and
reverse and measure again if the track tension
is correct after the adjustment.
NOTE!
For quality of grease please refer to the table of
fuels and lubricants on page
