WARNING: Be sure to slowly operate the boom. If
quickly operated, lever blocks (5) and/or wire rope
may be damaged and/or fly away, possibly causing
severe personal injury.
Stay away from the machine when operating the
boom.
10. Slightly slacken wire rope tension by operating lever
blocks (5) and raise the boom to slightly lower track
frame (2). Do not slacken wire rope tension excessively.
Also, take care not to lower track frame (2) excessively.
If excessively slackened or lowered, side frame (3) will
retract making re-tightening (by hand) of bolts difficult.
11. After slightly lowering track frame (2), re-tighten bolts (1)
by hand.
12. Repeat steps 10 and 11 three to four times until track
frame (2) is completely lowered to the ground.
13. Slacken lever blocks (5). Remove lever blocks (5) and wire
ropes.
14. Tighten bolts (1) with the power boost wrench and
torque wrench to specification.
Tightening Torque: Refer to the under table.
IMPORTANT: Be sure to apply a film of lubricant to the
bolt threads.
15. Extend side frame (3) on the opposite side in the same
procedure.
