Ransburg Overhead Electric Reciprocator ER-8100 - Manual (Page 23)

COMPONENT SUPPORT
PROCEDURES
To remove or replace many of the moving elements
of the reciprocator certain components must first
be supported by some mechanical means during
the removal and replacement process. Provisions
have been built into the machine to help simplify
the supporting task. However, one should be fully
aware that several components, depending on the
size of the reciprocator weight several hundreds
of pounds; and, if they are not supported proper-
ly they can fall and cause serious bodily injury,
including death.
Friction Brake Lockout
The friction brake [2], located at the top of the
6- inch tube [22], locks the 6 inch tube [22] to the
10- inch tube [21] if the drive chain [7] fails. When
disassembling or removing the 6 inch tube [22] the
friction brake [20] must be disengaged. One must
understand that with the brake [20] disengaged, the
6 inch tube [22] will fall if not properly supported.
The friction brake [2] has a 7/32 inch diameter
access hole drilled through the 1 1/2-inch diameter
support rod, which connnects to the drive chain
[7]. Under conditions where the 6-inch tube is
supported by the drive chain, the 7/32-inch di-
ameter access hole is exposed and a 3/16-inch
diameter pin can be inserted into the access hole
to lock the brake [20] in the open position. If one
is planning on removing the 6-inch tube [22],
the tube can be lowered into the paint booth for
maintenance purposes. The lockout pin must be
removed prior to running the machine.
Counter Balance Weight Support
The counter balance weight [1] can be supported
at the top of the weight tube [5] for maintenance
purposes. Jog the 6-inch tube [22] all the way
down and past the run-a-way limit switch. The
weight [1] will bottom out at the hard stop at the
top of the 6-inch square weight tube [5]. Insert
a 1/2 -inch diameter steel rod thru the two holes
located on the sides of the weight tube at the top
of the tube. With the weight [1] all the way up,
the steel rod, when inserted, will be under the
counter balance weight. Secure the steel rod as
appropriate to insure that it cannot be removed
or dislodged during the maintenance process.
Service can now be performed where the weight
[1] must be supported in position. Reconnect
the drive chain at the counter balance weight
(make sure that the chain is not twisted), if it was
disconnected during maintenance. Remove the
steel rod prior to running the machine.
>
DO NOT attempt to run the machine with
the counter balance weight [1] disconnected,
as serious bodily injury could occur.
