Gradall 534D-10 (9134-4052) Operation Manual - Manual (Page 34)

Fork Positioner
Capacity:
Maximum load capacity for fork positioner carriage is the same as standard
carriage without fork positioner. Refer to Attachment Capacity Chart.
Capacity varies with boom extension and elevation positions.
Controls:
Figure 13-1
The auxiliary control lever is used to adjust
fork position. Pull lever back to close forks,
push lever forward to open forks.
Installation Procedure:
1. Remove standard carriage/fork combination or other attachment from boom
head. (See “Attachment Installation” Page 13.1)
2. Install carriage/fork combination with positioner.
3. Connect auxiliary hydraulic hoses to positioner cylinders.
Operation:
• Always adjust fork position before engaging load. Moving forks after engaging
load could cause load to fall from forks.
Light Material Bucket
Capacity:
Maximum capacity of light material bucket is shown on the attachment serial
number plate and may be used in areas where it does not exceed capacities
shown on standard carriage/fork capacity chart. Capacity must be reduced for
areas where maximum bucket capacity would exceed standard carriage/fork
capacity chart.
Attachment Tilt Controls:
Figure 13-2
Because the carriage tilt cylinder is used to tilt the bucket, the carriage tilt
lever is used to control the bucket. Pull lever back to raise bucket lip push
lever forward to lower bucket lip.
Installation Procedure:
1. Remove carriage/fork combination or other attachment from boom head.
(See Page 13.1)
2. Install light material bucket on boom head.
3. Retract boom fully and tilt bucket up or down as required to position bottom
of bucket parallel with ground.

WARNING !
PRECAUTIONS
• Always adjust fork position
before engaging load.
• As with all other attachments,
handler must be level before
handling a load more than
four feet (1.2m) above
ground level. (See “Leveling
The Handler,” Page 11.0)
WARNING !
Observe all precautions and load
capacity limits (listed previously)
when handling loads with carriage/
fork positioner.
WARNING !
PRECAUTIONS
• Handler must be level before
handling a load more than
four feet (1.2m) above ground
level. (See Page 11.0)
• Retract boom fully before
loading bucket. Loading bucket
with boom extended could
damage structural members or
extension chains/cables.
• Avoid shock loads; drive into
stockpile smoothly to load
bucket.
• Do not use bucket as a lever to
pry heavy material. Excessive
prying forces could damage the
bucket.
• Do not use bucket for “back
dragging.” This could cause
severe damage to Quick Switch
fittings.
WARNING !
Observe all precautions and load
capacity limits (listed previously)
when handling loads with light
material bucket.
