on the O-ring fittings.
INSTALL
WARNING
The points between the scissor arms and the
outer frame is a pinch point and can cause an
injury. Do NOT put any part of your body be-
tween these assemblies. Use a screwdriver or
other tool to move the bearing blocks or assem-
blies into the correct positions.
1.
Use multipurpose grease to lubricate the bush-
ings on the inner and outer scissor arms. Use
multipurpose grease to lube the bottom bearings
in the channel at the bottom of the outer frame.
2.
Use a crane to lift the outer frame. Align the
outer frame with the outer scissor arms. Install
the pivot pins that retain the inner scissor arms
to the outer frame.
3.
Install the brackets and hardware to retain the
pivot pins.
NOTE:
The reach assembly must be installed on the
mast before starting Step 4.
4.
After all hydraulic lines are connected, operate
the functions to check for leaks and correct oper-
ation. Remove the air from the system and ad-
just the stroke of the tilt cylinder as described in
Carriage or Reach Assembly Adjustments.
5.
If necessary, install the forks and load backrest
as described in Fork Replacement and Load
Backrest Removal and Installation.
REMOVE WITHOUT SIDESHIFTER
WARNING
There are pinch points on the reach car-
riage that can cause an injury.
Use clamps
and blocks to prevent the scissor arms from
moving. Install the clamps and blocks at the
channels of the rear frame to make sure that
the load bearings cannot move in the channel.
See Figure 7.
CAUTION
Do NOT use steam to clean the load bearings.
Do not use compressed air on the bearings.
The bearings are sealed and permanently lu-
bricated. The air can force the lubricant out of
the bearings.
NOTE:
Use safety chains on the rear frame and mast
weldments to keep the reach assembly and mast
weldments from moving. Install the safety chains as
described in Safety Procedures When Working Near
Mast in this section.
1.
If necessary, remove the load backrest as de-
scribed in Load Backrest Removal and Installa-
tion.
2.
If necessary, remove the forks as described in
Fork Replacement.
3.
Install labels for correct connection during in-
stallation and remove the hoses at the top of the
outer frame. For units without sideshift, see Fig-
ure 8. For units with sideshift, see Figure 9.
Make a note of the location of all cable ties for
correct installation of new cable ties during in-
stallation. Install caps on the hydraulic lines of
the selector valve to prevent dirt from entering
the system.
WARNING
The points between the scissor arms and the
outer frame are pinch points and can cause
an injury. Do NOT put your finger in the hole
when you remove the pins. Use the brass drift
to remove the pins.
WARNING
The outer frame is heavy and can tip forward
and cause an injury when removed from the
scissor arms. Tipping is even more possible if
the forks or outer frame are installed. Make
sure to install the chains or slings between the
crane and outer frame to prevent tipping.
4.
Use a crane as a support for the outer frame. Use
a brass drift to remove the pivot pin that fas-
tens the outer frame to the top ends of the scissor
arms.
