How to loosen up or stretch the crawling track
The grease contained in the hydraulic crawling track is pressurised.
Do not loosen the valve by more than one turn; if the valve is loosened
too much, it may be blown off due to the pressure of the grease.
To loosen up the crawling track:
•
Slowly open the valve in the anticlockwise direction, not more than half a turn, to drain the grease.
If the grease does not come out turn the crawling track slightly.
•
Once the correct tension of the crawling track is obtained, close and tighten the valve in the clockwise
direction.
•
Clean any grease residues outside the mechanism.
To tense up the crawling track:
•
Connect the grease gun to the greaser.
•
Fill the track with the grease until the track tension reaches the correct value.
Perform the operations with the machine stabilised.
Never loosen the greaser.
