POWER SYSTEMS:

ELECTRIC MOTORS: All single
phase electric motors contain a
manual

automatic

thermal

overload, which will shut down the
motor if it overheats. If the overload

or starter shuts down the motor, have an electrician or
an  authorized  Hot2Go  dealer  check  for  electrical
problems.    Voltage  reading  under  load  should  be  +/-
10%  of  name  plate  voltage  on motor.   Wait for motor
to cool before re-setting. Depressing the red overload
button  located  on  either  the  motor  or  the  starter  can
reset the motor.  Use thumb pressure

– do not force.

If equipped with an automatic thermal overload, it will
reset itself after the motor has cooled.
Never spray water on the unit, or damage to the
electric motor(s) may occur.

Consult the manufacturer if running an electric
machine from a generator. Three times total
system wattage is required.

A  fused  disconnect  switch  of  sufficient  ampere  rating
should be installed by an electrician to provide  power
to the machine.  Note: Some dual rated 208-230 VAC
washers  include  a  control  circuit  power  selector
switch, located on the back of the control box.  Switch
it  to  the  appropriate  position  to  match  your  source
voltage.    Switches  are  set  by  manufacturer  to  match
recorded test sheet voltage.   Refer to the chart above
for  electrical  requirements.    If  your  unit  is  equipped
with  a  ground fault  interrupter,  it  will  have  to  be  reset
whenever  it  is  plugged  in,  or  if  a  ground  fault
interruption  occurs.    Test  regularly  for  proper
operation.

GASOLINE  ENGINE:    With  proper  care  and
maintenance,  your  gasoline  engine  will  give  years  of
trouble  free  service.    Please  follow  the  Service  and
Maintenance Guide and the enclosed engine sheet or

contact  your  local  authorized  engine
dealer for maintenance and repairs.
Use  clean,  fresh,  unleaded  gasoline
with  an  octane  rating  of 87  or  higher
in  the  engine  fuel  tank.    Up  to  15%
MTBE  (methyl  tertiary  butyl  ether)  or
10%  ethanol  is  acceptable.    Do  not

use  unapproved  gasoline  such  as  E15,  E20  or  E85
ethanol blends.    Any failures from use of these fuels
will  not  be  warranted.    Consult  engine  manual  for

proper  oil  type  and  capacity.    The  engine
manufacturer recommends a break-in period at which
time  the  engine  oil  and  filter  should  be  replaced.
Thereafter, change oil and filter as required by engine
manufacturer. Refer to engine manual for preventative
maintenance  schedules  and  procedures.    Do  not  rely
on the low oil shutdown (if equipped) as a reminder to
add  oil.    The  engine  manufacturer  will  typically  not
warranty  engine  damage  from  lack  of  oil  even  if  the
low oil system failed.
On machines with a 12V burner, the throttle is preset
by  manufacturer.    Some  engines  include  backfire
prevention solenoids.

POWER TRANSMISSION:
WARNING:

Shut off power supply before servicing.

BELT  DRIVE:    Check  belt  condition,  alignment  and
tension  periodically.    Replace  belts  when  they  show
signs of wear or cracking.  Tighten belts by loosening
the  mounting  bolts  on  the  pump  to  permit  them  to
slide.  Turn the horizontal rail adjusting bolts to tighten
belts until they deflect ¼" to ½” with finger pressure.
DIRECT  DRIVE:    Pump  is  bolted  directly  to  the
motor/engine.    If  pump  needs  to  be  removed,  do  not
force  off  by  prying  or  damage  may  occur.    When
reassembling,  coat  the  entire  motor  shaft  with  heavy
grease  or  a  generous  amount  of  anti-seize.    Use
“thread  locker”  or  “lock  tight”  on  mounting  bolts  and
tighten set screw on key shaft.

PUMPING SYSTEM:

PUMP:    The  pump  is  a  positive
displacement,  oil  bath  crankcase,
and  triplex  plunger type.    It contains
3 plungers, which move forward and
backward  in  a  cylinder  to  propel

water past 3 inlet valves and 3 discharge valves into a
high-pressure  manifold.  The  crank  case  oil  window
should  be  checked  for  oil  level  and  clarity  and  the
pump for oil or water leaks before each use.  The sight
window  is  located  at  the  rear  (opposite  the  head)  of
the  pump  and  should  be  filled  to  the  red  dot  with
specified  pump  oil,  available  at  your  Hot2Go  dealer
(refer to maintenance schedule on back page).  If the
oil  becomes  milky  in  color,  moisture  is  entering  the
crankcase.    Change  the  oil  and  contact  your
authorized Hot2Go dealer if the problem persists.
Keeping filters clean and checking for air in pump feed
lines  can  prevent  cavitation  and  increase  pump  life.
Do  not  run  pump  in  the  bypass  mode  (pump  running
with  the  trigger  gun  off),  for  a  period  of  more  than  5
minutes or the pump will begin to overheat (maximum
water  temperature  is  145°F).    Do  not  run  pump  dry.
Protect from freezing.  Do not run a frozen pump until
it is completely thawed.
