A GRAMMER seat is installed as standard equipment, which achieves excellent shock absorption and superior ride comfort.
Air is blown against the operator's waist and the back of their head, o�ering more comfortable operation.
Lever angles allow for comfortable operationsThe operator can move the levers horizontally without twisting their wrist, which reduces the fatigue caused by the operations.
The LED interior light automatically turns on when the
door is opened or when the ignition is set to OFF. This ensures easy entry and exit at nighttime.

iNDr FilterA high-density mesh �lter blocks dust intruding during air intake. This prevents the cooling device and the air cleaner from clogging with dust and maintains their performances. The ridges of the corrugated �lter allow the air to pass through, and the grooves collect the dust, which prevents the �lter from clogging.

A: Reach from swing centreline to arm topB: Arm top height above/below groundC: Lifting capacities in KilogramsBucket: Without bucketRelief valve setting: 29.4 MPa {300 kgf/cm2}
1. Do not attempt to lift or hold any load that is greater than these lift capacities at their speci�ed lift point radius and heights. Weight of all accessories must be deducted from the above lift capacities.
2. Lift capacities are based on machine standing on level, �rm, and uniform ground. User must make allowance for job conditions such as soft or uneven ground, out of level conditions, side loads, sudden
stopping of loads, hazardous conditions, experience of personnel, etc.
3. Arm top de�ned as lift point.
4. The above lifting capacities are in compliance with ISO 10567. They do not exceed 87% of hydraulic lifting capacity or 75% of tipping load. Lifting capacities marked with an asterisk (*) are limited by
hydraulic capacity rather than tipping load.
5. Operator should be fully acquainted with the Operator’s and Maintenance Instructions before operating this machine. Rules for safe operation of equipment should be adhered to at all times.
6. Lift capacities apply to only machine as originally manufactured and normally equipped by KOBELCO CONSTRUCTION MACHINERY CO., LTD.

1. Do not attempt to lift or hold any load that is greater than these lift capacities at their speci�ed lift point radius and heights. Weight of all accessories must be deducted from the above lift capacities.
2. Lift capacities are based on machine standing on level, �rm, and uniform ground. User must make allowance for job conditions such as soft or uneven ground, out of level conditions, side loads, sudden
stopping of loads, hazardous conditions, experience of personnel, etc.
3. Arm top de�ned as lift point.
4. The above lifting capacities are in compliance with ISO 10567. They do not exceed 87% of hydraulic lifting capacity or 75% of tipping load. Lifting capacities marked with an asterisk(*) are limited by
hydraulic capacity rather than tipping load.
5. Operator should be fully acquainted with the Operator’s and Maintenance Instructions before operating this machine. Rules for safe operation of equipment should be adhered to at all times.
6. Lift capacities apply to only machine as originally manufactured and normally equipped by KOBELCO CONSTRUCTION MACHINERY CO., LTD.
