OTHER ADJUSTMENTS AND REPLACEMENTS
PURGING OF THE FUEL SYSTEM
1. Fill up the excavator with fuel.
2. Turn the starter key to the position "ON".
3. The air in the fuel system will be purged
within one minute.
A If the purging was insufficient, and the
engine dies immediately after starting. In this
case repeat steps (2) to (3) again.
ADJUSTMENT OF CRAWLERS
C To loosen the crawlers, follow the
following procedure:
To avoid personal injury:
A Do not loosen the grease nipple
completely or too quickly. Otherwise
grease under high pressure in the
tension cylinder could squirt out.
A Do not crawl under the excavator.
1. Using a socket wrench, loosen the grease
nipple a few turns.
2. When grease oozes out from the thread,
rotate the crawler and loosen the crawler in
the lifted position (see illustration).
After adjustment is completed:
Using the socket wrench, tighten the grease
nipple.
Tightening torque must be between 98 to 108 N-
m (10 to 11 kgf-m).
A If the crawlers are too tight, wear is
increased.
A If the crawlers are too loose, the crawler
shoes may collide with the sprocket, and
wear is increased.
The crawler may dislocate or come off.
A Clean the crawler after every use.
A Should the crawler tension be heightened
due to mud sticking, lift the crawler with the
help of the boom, arm and bucket, idle the
engine and remove the mud from the
crawler, especially from the openings of the
link plate, carefully.
C Tension the crawlers as specified:
1. Apply grease to the grease nipple (1).
(A) "PREHEAT"
(B) "OFF"
(C) "ON"
(D) "START"
(1) Grease nipple
(2) Grease gun
