ASSEMBLY INSTRUCTIONS
1. Attach the handle to the front of the top cover using 4
sets of 1/4"--20 X 5/8-in. screws and lockwashers (see
Figs. 1 and 2).
NOTE: If the top cover and rear panel do not have
holes and weldnuts, it will be necessary to
remove the cover from the unit to assemble
the handle and the cylinder rack using the
extra 1/4-in. flat washers and 1/4--20 hex nuts
supplied. (See Fig. 1.) Be sure to replace
the top cover after assembling the truck to
the power source.
If the cover does not have mounting holes,
use the handle as a template and drill the
holes. The two front holes should be located
so that screw and nut will be located just behind the flange in the front panel.
2. Attach the upper cylinder rack to the top of the rear
panel as illustrated in Fig. 2, using 4 sets of 1/4" --20
X 5/8-in. screws and lockwashers.
NOTE: If the rear panel does not have mounting
holes, use the rack's mounting bracket as a
template to drill the four holes. Locate the
mounting bracket as close to the top of the
unit as possible.
Some units (depending on the model) may
already have screws in the rear panel where
F-12-888-E
the cylinder rack mounting screws are to go.
If this is the case, use them to help mount
the cylinder rack.

a. Lift the unit off the floor (using a crane or hoist and
the lifting eye, or a suitable jack), and remove the
wooden skids.
b. Assemble the front beam and swivel casters to the
front base of the unit using 8 sets of 3/8" --16 x 1in. long screws, lockwashers, flatwashers and nuts
