Model G0925 (Mfd. Since 02/20)

SHOCK HAZARD. Working on wiring that is con-
nected to a power source is extremely dangerous. 
Touching  electrified  parts  will  result  in  personal 
injury  including  but  not  limited  to  severe  burns, 
electrocution,  or  death.  Disconnect  the  power 
from the machine before servicing electrical com-
ponents!

MODIFICATIONS.  Modifying  the  wiring  beyond 
what is shown in the diagram may lead to unpre-
dictable  results,  including  serious  injury  or  fire. 
This includes the installation of unapproved after-
market parts.

WIRE CONNECTIONS.  All  connections  must 
be  tight  to  prevent  wires  from  loosening  during 
machine  operation.  Double-check  all  wires  dis-
connected or connected during any wiring task to 
ensure tight connections.

CIRCUIT REQUIREMENTS.  You  MUST  follow 
the requirements at the beginning of this manual
when connecting your machine to a power source. 

WIRE/COMPONENT DAMAGE. Damaged wires 
or  components  increase  the  risk  of  serious  per-
sonal injury, fire, or machine damage. If you notice 
that any wires or components are damaged while 
performing  a  wiring  task,  replace  those  wires  or 
components.

MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the 
motor junction box.

CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for 
up  to  10  minutes  after  being  disconnected  from 
the  power  source.  To  reduce  the  risk  of  being 
shocked, wait at least this long before working on 
capacitors.

EXPERIENCING DIFFICULTIES. If you are expe-
riencing difficulties understanding the information 
included  in  this  section,  contact  our  Technical 
Support at (570) 546-9663.

These pages are current at the time of printing. However, in the spirit of improvement, we may make chang-
es to the electrical systems of future machines. Compare the manufacture date of your machine to the one 
stated in this manual, and study this section carefully.

If there are differences between your machine and what is shown in this section, call Technical Support at 
(570) 546-9663 for assistance BEFORE making any changes to the wiring on your machine. An updated 
wiring  diagram  may  be  available. 

Note:  Please gather the serial number and manufacture date of your 

machine before calling. This information can be found on the main machine label.
