Lowering the Height of the Machine
To lower the machine, you will need the help of an
assistant. With one person holding up and sup-
porting the base of the machine, loosen the Lock
Knob, pull out the Spring Pin and set the Knob
Key into the shallow slot of the spring pin housing.
Carefully lower the machine base until it comes
to rest on the top of the Lower Column. Pull out
the Spring Pin and position the Knob Key into the
deep slot of spring Pin housing. Lift the machine
base until the Spring Pin engages the fi rst tooth
of the Gear Track and tighten the Lock Knob, or
continue raising the machine until the desired height is reached and then tighten the Lock Knob.
Raising the Height of the Machine
To raise the height of the machine, the Knob Key
of the Spring Pin should be positioned in the deep
slot of the housing to ensure that the Spring Pin
is in the Self-Locking position and engaged with
the Gear Track. Loosen the Lock Knob and with
the help of an assistant, lift the machine base until
the desired height is reached. When the desired
height is reached, tighten the Lock Knob.
Attaching the Floor Stand to the
Machine Base
Refer to the instruction sheet provided with
the fl oor stand for detailed instructions on
which holes of the fl ange plate to use and
align with the threaded inserts located in the
slots on the underside of the machine base.
With the fl oor stand assembled and the up-
per column locked into position at the lowest
height, orient the fl oor stand so that the string
reel holder will be positioned on the left side
of the machine base and bolt the fl oor stand
to the underside of the machine base. The
fl oor stand can be assmbled to the machine base with the machine base laying on the fl oor,
or by setting the machine base on top of the fl oor stand with the help of an assistant to align
and balance the machine base on the fl ange plate while installing and tightening the bolts
from the underside.
Caution: To prevent damaging the threads of the inserts in the machine base, do not over-
tighten the bolts.
