12 Remove the level sensor box mounting

fasteners and slide the box towards the non-
steer end of the machine as far as it can go.

Component damage hazard. Be
careful not to damage the level
sensor box, limit switch, level
sensor or wiring while moving the
level sensor box.

13 Secure the ends of the scissor arms together at

both ends of the machine with a tie down strap
or other appropriate device.

14 Remove the pin retaining fasteners from the

number 1 inner arm pivot pins (item #9) at the
steer end of the machine. Use a slide hammer
to remove the pins.

15 Attach a lifting strap from an overhead crane to

the steer end of the scissor arms.

16 Carefully slide the forks from a forklift under the

scissor arms at the non-steer end of the
machine.

17 Raise the scissor arms up until the number 1

inner arm will clear the level sensor box.

Component damage hazard. Be
careful not to damage the level
sensor box, limit switch or level
sensor while moving the scissor
assembly.

18 Move the scissor assembly towards the non-

steer end of the machine slightly and to one
side of the machine until one of the scissor arm
wear pads is accessible. Do not allow both
wear pads to slide out of the drive chassis.

Crushing hazard. The scissor

assembly will fall if both wear pads
are allowed to slide out of the drive
chassis.

19 Remove the old wear pad.

Note the position of the wear pad
before it is removed so when the
new one is installed it will be in the
correct position.

20 Install the new wear pad.

21 Move the scissor assembly towards the other

side of the machine until the other scissor arm
wear pad is accessible.

Crushing hazard. The scissor

assembly will fall if both wear pads
are allowed to slide out of the drive
chassis.

22 Remove the old wear pad.

Note the position of the wear pad
before it is removed so when the
new one is installed it will be in the
correct position.

23 Install the new wear pad.

24 Slide the scissor assembly back into the drive

chassis.

25 Lower the scissor assembly into position and

install the pivot pins.

Component damage hazard. Be
careful not to damage the level
sensor box, limit switch or level
sensor while installing the scissor
assembly.
