Loading Operations - Komatsu GALEO HM350-2 Operation & Maintenance Manual

OPERATION
(C): Manual actuation of inter-axle differential lock, and actuation of front, center, rear axle left and right differential
lock
Use this when the maximum rim pull is needed.
REMARK
If the tires slip or there is a difference in the rotating speed of the tires when the inter-axle differential lock switch
is at AUTO, the inter-axle differential lock is automatically actuated to set to condition (C).
When the left and right differential lock is actuated, the steering wheel will become more difficult to operate, so
be particularly careful when traveling around sharp curves.
WHEN TIRES ARE STUCK IN GROUND
If the wheels get stuck, to stop the wheels from spinning, do as follows.
If it is impossible to get the machine out even when repeating the procedure below, use a bulldozer to tow the
machine out.
1. Release the accelerator pedal to stop the wheels from spinning.
2. Actuate the inter-axle differential lock and all the left and right differential locks.
3. Depress the left and right differential lock pedal, set to the gearshift lever to position "5", and raise the engine
speed.
4. Release the accelerator pedal and brake pedal.
5. Depress the left and right differential lock pedal, set to the gearshift lever to position "R1", and raise the engine
speed.
6. Repeat Steps 1 - 5 to move the machine backwards and forwards until it can escape.

LOADING OPERATIONS

When using a large wheel loader to load large rocks, if the rocks are loaded directly into the dump body parts of the
dump body may be deformed. To prevent this, when loading large rocks, first load sand or soil to act as a cushion,
then load the rocks on top of this to reduce the impact on the dump body.
In addition, when loading rocks that exceed the following conditions, install the optional dump body reinforcement
plate.
Rocks with one side over 0.3 m (11.8 in)
Rocks of hardness more than 4.5 (Mohs scale)
Rocks with a weight of more than 150 kg (331 lb)
When transporting steel ingots
NOTICE
When traveling, always set the dump lever to the FLOAT position regardless of whether the dump body is empty or loaded.
If the dump lever is not at the FLOAT position and the shift lever is not at the N position, the central warning lamp will flush and
the alarm buzzer will sound.
