Cold Start; Recoil Starter; Before Stopping - Sears Craftsman 247.88790 Manual De Uso

Cold Start

NOTE: If the unit shows any sign of motion (drive or augers) with the
clutch grips disengaged, shut the engine off immediately. Readjust as
instructed in the "Final Adjustments" section of the Assembly Instruc-
tions.
WARNING: The electric starter must be properly
grounded at all times to avoid the possibility of elec-
tric shock which may be injurious to the operator.
1. Determine whether your house wiring is a three-wire grounded
system. Ask a licensed electrician if you are not certain.
WARNING: If your house wiring system is not a
three-wire grounded system, do not use this electric
starter under any conditions.
a. If your house wiring system is grounded and a three-hole
receptacle is not available at the point the snow thrower starter
will normally be used, one should be installed by a licensed
electrician.
b. When connecting the power cord, always connect cord to
starter on engine first, then plug the other end into a three-hole
grounded receptacle.
c. When disconnecting the power cord, always unplug the end
from the three-hole, grounded receptacle first.
2. Attach spark plug wire to spark plug.
3. Make sure that the auger and drive controls are in the disengaged
(up) position.
4. Move throttle control lever to FAST position.
5. Push key into the ignition slot and snap in place. Do not turn key.
6. Connect power cord to switch box on the engine.
7. Plug the other end of the power cord into a three-hole, grounded
120 volt A.C. receptacle.
8. Rotate choke knob to FULL choke position (cold engine start). If
engine is warm, place choke in OFF position instead of FULL.
9. Push the primer three times.
10.Push down on the starter button until the engine starts. Do not
crank for more than 10 seconds at a time. This electric starter is
thermally protected. If overheated, it will stop automatically and can
be restarted only when it has cooled to a safe temperature (a wait
of 5 -10 minutes is required).
11. When the engine starts, release the starter button and slowly rotate
the choke to OFF position. If the engine falters, rotate the choke to
FULL and then gradually to OFF.
12.Disconnect the power cord from the receptacle first and then from
the switch box on the engine.
13.Allow the engine to warm up for a few minutes because the engine
will not develop full power until it reaches operating temperature.
Operate the engine at full throttle (FAST) when throwing snow.
OPERATION

Recoil Starter

Make sure that the engine has sufficient oil and the auger drive and
the drive control levers are released.
Cold Start
1. Move throttle control to FAST position.
2. Turn fuel valve on, if so equipped.
3. Push key into the ignition slot and snap in place. Do not turn key.
4. Rotate choke control to FULL choke position.
5. Push the primer button while covering the vent hole. Remove your
finger from the primer between primes. Do not prime if temperature
is above 50º F; prime two times between 50º F and 15º F; and
prime four times below 15º F.
6. Pull the starter handle rapidly. Do not allow the handle to snap
back, but allow it to rewind slowly while keeping a firm hold on the
starter handle.
7. As the engine warms up, rotate the choke knob slowly to OFF
position. If the engine falters, return to FULL choke, then slowly
move to OFF choke position.
8. Allow the engine to warm up for a few minutes because the engine
will not develop full power until it reaches operating temperature.
9. Operate the engine at full throttle (FAST) when throwing snow.
Warm Start
If restarting a warm engine after a temporary shut down, rotate choke
to OFF instead of FULL and do not prime. Pull starter handle as
instructed earlier.
NOTE: Allow the engine to warm up for a few minutes as the engine
will not develop full power until it reaches operating temperature.
Frozen Recoil Starter
If the starter is frozen and will not turn the engine, proceed as follows:
1. Pull as much rope out of the starter as possible.
2. Release the starter handle and let it snap back against the starter.
3. If the engine still fails to start, repeat the first two steps. If continued
attempts do not free starter, follow the electric starter procedures to
start.
4. Avoid freezing of the recoil starter by referring to instructions below.

Before Stopping

1. Run engine for a few minutes to help dry off any moisture on
engine.
2. Avoid freezing of the starter by following these steps before stop-
ping the snow thrower:
