NOTE: The above loads are in compliance with the SAE standard J1097 DEC2005.
They do not exceed 87% of hydraulic lifting capacity or 75% of tipping capacity.
The rated lift capacity is based on the mac hine being equipped with 4,500 lb (20 41 kg)
counter weight, standard boom, standard tires, no auxiliary hydr aulics and no bucket.
NOTE: Bucket adjustment values are 87% of the actual buc ket weights .
The load p oint is located on the bucke t pivot point , including load listed fo r maximum radius.
Do not at tempt to lif t or hold any load greater tha n these rate d values at spe cified load radii and
heights. The weight of slings and any auxiliar y devices must be deduc ted from the rated load to
determine the net load that may be lif ted.

ATTENTION: All rated loa ds are based o n the machine being stationary and level on a firm
suppor ting sur face. For safe working loads, the user must make allowance for his particular job
condit ions such as soft or uneven ground, ou t of level conditions, side loads, ha zardous
condit ions, expe rience of personnel , etc. The operator and ot her personnel must fully acquaint
themselves with the Operator’s Manual furnished by the manufacturer before operating this
machine . Rules for safe operation of equipment must be adher ed to at all time s.
