Note: If oil level is too low, oil alert system
will keep engine from starting (see Oil Alert
System, page 6). Make sure oil level is full
before starting. See Engine Oil, page 7.
Before starting the engine, disconnect all
electric loads from generator.
STARTING
IMPORTANT: The engine speed is preset.
The throttle is locked in preset position. Do
not adjust throttle. Preset position lets engine
run at 3600 RPM under load. The engine
must maintain 3600 RPM for generator to
create correct voltage. Running engine at
lower speeds will damage generator and
powered items.
IMPORTANT: Never start generator with
electrical loads connected. Start engine
before adding electrical loads.
1. Make sure gasoline tank is full. See
Fuel, page 7 for fuel information.
2. Move fuel valve lever to the ON posi-
tion except on Model MGR6000I (see
Figure 10).
3. Move choke lever fully to the left for all
models except MGR6000I (see Figure
10). Pull choke button out for Model
MGR6000I (see Figure 11). This closes
the choke.
Note: You may not need to close choke
if engine is warm or air temperature is
high.
WARNING: Only responsible
adults should use generator.
Never let anyone operate genera-
tor without proper instructions.
PRESTART
Operate generator on a firm, dry, and clean
surface. The surface must be level. Protect
generator from heavy dust, sand, dirt, rain,
or snow. Do not locate generator near
standing water and snow. Make sure area
is well-vented.
4. Start the engine.
Turn engine switch to the ON position
(see Figure 12). Remove slack from
starter rope by lightly pulling starter
grip. Next, pull starter rope briskly.
IMPORTANT: Do not let starter grip
snap back against engine. Return it gen-
tly. This will prevent damage to starter.
Note: If engine does not start, check
the oil in the crankcase. Add oil as
necessary. Be sure engine is on a level
surface. See Oil Alert System, page 6.
5. As engine warms up, slowly move choke
lever fully to the right (see Figure 13)
(all models except MGR6000I). This
opens the choke. On Model MGR6000I,
slowly push in choke button until fully
depressed (see Figure 14).
