e. Tighten tension adjustment bolt on left side
of rotary actuator mounting plate to increase
belt tension (belt
should be snug, but not
overtightened).
f. Close and secure cover on control panel;
reset EMERGENCY STOP push button;
manually run program for rotating mounting
plate using the BLOCK FORWARD CON-
TINUOUS mode, and check receiver hole
location after rotating mounting plate to op-
posite side.
4. Press RESET key on Program Module, and press
and EMERGENCY STOP push button.
5. Tighten the 4 nuts to secure rotary actuator
mounting plate to turntable base.
6. Install front, rear, and left side covers on turn-
table chassis.
7. Install hard stop assembly onto both sides of
turntable chassis.
8. Reset
EMERGENCY STOP push button, and ad-
just hard stops according to Section 4-8.
4-12. HYDRAULIC FITTINGS
care when retightening the connection. Compression
fittings with free-turning nuts can crack or break if over-
tightened.
4-13. RELEASING PRESSURIZED FLUID FROM
ACCUMULATOR (Figure 4-12)
-
The
accumulator
contains pressurized hydraulic fluid during turntable
operation and after the hydraulic system is shut down.
To release pressurized hydraulic fluid from accumulator,
proceed as follows:
WARNING: ELECTRIC SHOCK can kill.
• Do not touch live electricalparts.
• Shut down turntable, welding power source, and
robot contro4 and disconnect input power
employing ‘lockout/tagging procedures” before
inspecting or servicing.
Lockout/tagging procedures consist of removing plug
from receptacle, padlocking line disconnect switch in
open position, removing fuses from fuse box, or shut-
ting off and red-tagging circuit breaker or other discon-
necting device.
MOVING PARTS can cause serious injury.
• Keep clear of pinch points.
PRESSURIZED HYDRAULIC FLUID can cause
serious injury.
• Release hydraulic fluid pressure according to Sec-
tion 4-13 before touching any hydraulic com-
ponents.
Hydraulic fluid pressure is present even though elec-
trical power is disconnected.
The turntable hydraulic system uses two types of fit-
tings for making connections between components.
Pipe fittings have tapered threads, and the seal between
connections is provided by teflon tape. Compression fit-
tings have straight threads, and the seal between con-
nections is metal to metal contact when fittings are
tightened together.

1. Remove front and rear cover from turntable
chassis.
If a pipe fitting connection is loosened or completely
disconnected, clean the threads on the male and female
fittings, and apply teflon tape to threads on male fitting
to reseal the connection. If a compression fitting con-
nection is loosened or completely disconnected, use
IMPORTANT: The use of adequate force is needed
to press the push button because hydraulic fluid is
pressurized at the push button to the hydraulic system
operating pressure of 950 to 7250 psi (6550 to 8618
kPa).
