Boom Lift Adjustment
If slack occurs (= forward and backward movements of the boom), the
glide shoes (A) should be adjusted. To locate all 4 sets of glide shoes:
See “Lubrication Plan - Boom Centre” on page 121.
1.
If there is too much space between the glide shoe (B) and the steel
frame, extra shims (C) should be mounted in between.
2.
If the glide shoe (B) or the shims (C) are worn, they should be
replaced.
3.
Loosen the bolts and nuts to separate the parts. Replace parts as
needed and tighten the bolts and nuts again.
4.
Each glide arrangement should be adjusted, until the same
clearance has been reached at all 4 gliding points on the boom lift.
˜
ATTENTION! It is very important that the boom carrier does not
run unequally in the H-frame. It is important that there is no play
in any of the glide shoes.
