SERVICE PROCEDURE
CHECK, CLEAN AUTOMATIC SUSPENSION
WARNING
If for any reason the maintenance is performed while the engine is running,
strictly follow the next rules.
One should sit on the operator's seat, preparing to stop the engine at
any moment, and contact with the other.
Set the dump lever at HOLD position to prevent the dump body from
moving. Also, set the parking brake valve lever at PARKING position to
prevent the machine from moving.
When working near fan or belts, do not bring your body or any materials
closer that can be dragged into.
Do not touch the gear shift lever or dump control lever. If you have to
operate the gear shift lever or dump control lever for any reason, always
give a signal to your fellow workers to tell them to move to a safe place.
If the materials or tools are dropped onto fan or belts, they fly away or
cut. Never drop or insert materials or tools.

When bolts of inspection cover (1) are loosened and the cover
is moved to the side, the inspection hole can be seen.

Check the positions of the link. Check that it moves to the
following positions:
For normal travel when empty: soft
When the brake is depressed: medium
When the dump lever is at any position other than FLOAT:
hard.
If any problem is found, please contact your Komatsu distributor for inspection and adjustment.
If operations are carried out on muddy or wet ground, mud will stick to the link, and the movement may become slow,
so check and clean.
