RIDE STABILIZING MECHANISM
4.21.1. DRIVING A MACHINE WITH RSM SYSTEM
The RSM mechanism is switched on with a double-pole switch fitted with a illuminating light located
on the left hand side of the instrument panel (Fig. 4.2 and 4.2A). It has two positions: ON and OFF.
On turning the switch on, the stabilizing mechanism is actuated as soon as the machine speed
exceeds 5 [km/h], the minimal speed at which pitching occurs.
It is not recommended to switch on the mechanism while carrying spoil at short distances as
sudden "“jumps" of the bucket up to 250 [mm] can occur.
NOTE: If pitching persists even when the RSM mechanism is on, contact an Authorized Dealer of
Construction Machines, to correct the cause. Do not perform any repairs of either the valves or
hydraulic accumulators on your own.
4.22. HIGH-DUMP BUCKET
The high-dump bucket is one of optional auxiliary equipment mounted on a 515C loader fitted with a
3-spool control valve. The assembly consists of a bucket, bucket frame and cylinders.
The assembly is installed on the boom. Any other bucket can be installed instead of the high-dump
bucket (Refer to HIGH-DUMP BUCKET, Section 6).
To keep the rules of work safety and proper machine use to protect its excessive wear and the
wear of the hydraulic system do not use the high-dump bucket in the soil, whose specific gravity is
greater than 1300 [kg/m
3
]. Working in soils exceeding this gravity, particularly when the bucket is full
can damage the hydraulic system or cause the loss of stability and machine tipping over.
4.22.1. HIGH-DUMP BUCKET CONTROL
The bucket is controlled with a lever from the operator’s cab. The lever is located on the left of the
standard bucket control lever or on the right of the boom and bucket control lever in upgraded
version.
BUCKET OPENING
To open the bucket, push the control lever forward. When released the lever will automatically
return to the hold position.
BUCKET CLOSING
To close the bucket, pull the control lever back. When released the lever will automatically return to
the hold position.
4.22.2. OPERATING THE HIGH-DUMP BUCKET
Load the bucket and raise it up to the standard maximal height of dump in the same manner as the
standard bucket. Then with the bucket still closed, push the high-dump control lever forward. The
bucket will start opening while the boom is continuing to rise higher then the standard dump height.
After dumping pull the high-dump control lever back, drive the machine away from the dumping
place, lower the boom and steer the machine to the working area.
