NOTE:
• For service of the boom, that is to be extended greater than 120 ft, the counterweight must be installed on the turntable and the
outriggers must be fully extended. Superstructure could be in any slew position. No rigging, no hookblock nor overhaul ball may
be installed on the nose of the boom. Extend boom to desired length at a boom angle of 20°. Lower boom until RCL limits the
boom lower function. Override RCL per RCL operators manual and lower boom to desired angle.
• Should boom chatter or rubbing noises in the boom occur, it will be necessary to lubricate the telescope cylinder wear
pads. By adding an extension adapter to a grease gun the wear pads and wear areas can be reached through the
lubrication access holes in the side of the boom and through the access hole in the boom nose between the sheaves.
• Lubricate more frequently than interval indicated in table if environmental conditions and/or operating conditions
necessitate.
