INSTRUCTIONS
Electric Disk Reciprocator
Maintenance
Prior to performing any maintenance on the
electric reciprocator it is important to thoroughly
understand the machine construction and to have
read the manuals and documentation. The re-
ciprocator moving mechanism consists of heavy
components, which if not handled and supported
properly, can fall and cause serious bodily injury,
including death. Consequently, components must
be supported during many phases of maintenance
and repair. Only trained and skilled personnel
should be allowed to service and repair this ma-
chine. Further, do not under any circumstances
attempt to repair this machine unless it is electri-
cally “locked-out” and all reciprocating elements
such as the 6- inch diameter telescoping tube
assembly, counter balance weight, drive chain,
etc. are properly supported.
Reciprocator maintenance frequency is directly
related to production levels, over spray condi-
tions, machine speeds, live loads, etc. periodic
and regular inspection, as well as cleaning and
lubrication of components, is prudent and will
maximize uptime. The recommended intervals
of inspection and lubrication are only intended as
a guide. The specific frequency will need to be
determined as a result of the actual production
conditions.
500 Hour Inspection:
1. To gain access to the motor/speed reducer
[15], limit switches [2, 17, 18] and related drive
components, remove the two (2) 1/4”-20 hex head
cap screws at the outer edges of the sheet metal
motor house [1]. The motor house [1] is located
at the top of the 10-inch diameter tube. There
is one (1) cap screw on each corner on the near
and back side of the motor house [1]. With the
screws removed on either end, the motor house
[1] can be pivoted on the two (2) remaining screws.
Pivot the motor house [1] up and support it in the
open position.
2. Inspect the drive chain [7] and sprocket [16]
for signs of wear. Clean and replace worn com-
ponents as necessary. Brush-coat the chain [7]
and sprocket [16] with MPG silicone-free grease.
3. With the 6-inch tube in the extended position,
the weight tube guides [C83] can be seen from
the top of the 6 inch square weight tube [5]. The
weight guides [C83] are located on the top and
bottom edges of the counter weight [1]. Lubricate
with MPG grease. Generally, the weight guides
require very little lubricant. Your machine may have
an access cover on the bottom of the weight tube.
If so, inspection and lubrication can be performed
via this access cover.
4. Check the bolts on the motor/gear reducer [15],
limit switch mounts and cams [2, 8, 17], stop plate
and stops [3] for tightness. Re-torque if necessary.
5. To gain additional access to the motor [15], en-
coder, and terminal box [EDR-C-E1-1127], replace
the two (2) 1/4”-20 HHCS which were previously
removed from the end of the motor house [1] can
now be opened from the other end. Swing the
motor house [1] upward and rest it on the side of
the 10-inch diameter tube [21].
6. Check the motor encoder cable and encoder
connector for signs of wear and verify that the
cable connector is tight.
7. After servicing, return the motor house [1] to
its closed position and re-install the two (2) 1/2”-
20 HHCS screws. Tighten the four (4) screws to
secure.
>
If the motor house is allowed to open to
the extreme, it will bottom on the encoder.
thus, be very careful not to damage the
encoder when opening the motor house.
