STARTING
THE
MACHINE

level.
Open
(counterclockwise)
the
service
valve
on
the
propane
tank
about
one
and
a
half
turns.
Next,
see
to
it
the
Start/Stop
clutch
button
(2)
is
in
stop
position
check
the
throttle
(3)
in
the
IDLE

This
creates
a
vacuum
necessary
to
open
the
lock
‐
off
valve
inside
the
regulator.
Actuation
of
the
throttle
lever
will
keep
the
lock
‐
off
valve
from
opening
and
the
engine
from
getting
fuel
so
the
engine
will
not
start.
Proper
maintenance
will
insure
easy
starting.
Engage
starter
(1)
for
a
MAXIMUM
of
5
to
6
seconds
or
until
the
engine
fires.
Serious
starter
damage
will
result
if
this
is
exceeded
and
the
warranty
may
not
apply.
Operate
the
engine
at
half
throttle
for
approximately
two
minutes
for
proper
warm
