PURGING OF THE FUEL SYSTEM
1.
Fill up the excavator with fuel.
2.
Turn the starter key to the “RUN”
position.
3.
The air in the fuel system will
automatically be purged within one
minute.
(1) Starter key (A) “STOP”
(B)
“RUN”
(C)
“START”
IMPORTANT:
If the purging was insufficient, the engine
dies right after starting. In this case repeat
steps 2 to 3 again.
ADJUSTMENT OF TRACKS
To loosen the tracks, follow the following
procedure:
CAUTION
To avoid personal injury:
Do not loosen the grease nipple
completely or too quickly.
Otherwise grease under high
pressure in the tension cylinder
could squirt out.
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 track and loosen the track in the
lifted position (see illustration).
After adjustment is completed:
Using the socket wrench, tighten the grease
nipple.
Tightening torque must be between 72 to 80
ft·lbs (98 to 108 N·m, 10 to 11 kgf·m).
IMPORTANT:
If the tracks are too tight, wear is
increased.
If the tracks are too loose, the track pads
may collide with the sprocket, wear is
increased.
The track may dislocate or come off.
Clean the track after every use.
Should the track tension be high due to
sticking mud, lift the track with the help
of the boom, arm and bucket, idle the
engine and remove mud from the track by
rotating it.
