LIFTING CAPACITIES

1. Do not attempt to lift or hold any load that is greater than theserated values at their specified load radius and height. Weight of allaccessories must be deducted from the above lifting capacities. 2.Lifting capacities are based on machine standing on level, firm, anduniform ground. User must make allowance for job conditions suchas soft or uneven ground out of level conditions, sudden stopping ofloads, hazardous conditions, experience of personnel, etc. 3. Ratingsat bucket lift hook. 4. The above rated loads are in compliance withSAE Hydraulic Excavator Lift Capacity Rating Standard J 1097. Theydo not exceed 87% of hydraulic lifting capacity or 75% of tippingload. Rated loads marked with asterisk (*) are limited by hydrauliccapacity rather than tipping load. 5. Operator should be fullyacquainted with the Operator's and Maintenance Instructions beforeoperating this machine and rules for safe operation of equipmentshould be adhered to at all times. 6. Capacities apply to only machineas originally manufactured and normally equipped by KOBELCOCONSTRUCTION MACHINERY CO., LTD.
