Crawler tension - check/adjust
When parking an machine with rubber crawlers, ensure that the
seam ( ) is on top half way between the two sliders (see figure/1,
"Crawler tension - check", page 210).

Clean all parts of the running gear, paying particular attention
to stones between the crawler and sprocket or idler. Clean the
area of the crawler tensioning cylinder.

Swivel the swivel frame 90° to the direction of travel as shown
in the figure.

Lower the front attachments on the ground and raise the ma-
chine about 200 mm off the ground on one side.
Crawler tension - check

The crawler seam (3) is on the top halfway between the idler (1)
and sprocket (2).

Check the crawler sag as shown in the figure.
Crawler sag "A" 10-15 mm

If the crawler sag is more than 15 mm, adjust the crawler.

If necessary, tighten or loosen the crawler.

Start the engine and rotate the lifted crawler briefly.
If the crawlers are too tight, wear is increased.
If the crawlers are too loose, wear is increased and the crawlers may come off.
Have a guide supervise the procedure.
Do not work under the machine, when lifting the machine itself with the attachment.
Support the machine with a safety block or safety post and keep the lock lever for attachment control
in the “LOCK” position.
Crawlers with an SP mark can be checked and ten-
sioned in any position.
