OP000596 Safety
1-48
EXCAVATOR RATED LIFT
CAPACITY TABLES
To operate safely the excavator should be on a firm, level and
uniformly supporting surface. The operator is expected to make
due allowance for all specific work site and lift related conditions,
and respond to changes in those conditions that could pose a
hazard. The following could all cause hazardous conditions and
accidents or injuries:
• Soft or uneven ground.
• Unlevel terrain.
• Side loads.
• Modifications or poor maintenance of the excavator.
• Failure to lift squarely over the end or over the side of
the machine.
When a load is in the air, the operator must remain alert.
• Avoid side loads that may be caused by uneven
slings, traveling with the load or swinging too quickly.
• The load can become unbalanced if the hook line is
twisted and starts to rotate. If the surface area of the
load is large enough, wind gusts can create side
loads.

WARNING!
Let everybody be away from the boom cylinder. While
lifting operation, boom, arm, bucket hoses might burst
and then high-pressure oil will be ejected at high speed.
If that failure mode takes place, handling weight or front
structure might fall by its gravity to the ground to cause
fatal injury to the person.
When changing the hoses record the part numbers of
the hoses to factory log book.
Do the service job under the company's serviceman.
WARNING!
All rated lift capacities are based on the machine and
the load both remaining level at all times. DO NOT
EXCEED THE RATED LIFT CAPACITY. Lifting loads
greater than those shown in the rated capacity tables
can cause catastrophic equipment failure and/or
structural collapse of the machine.
