Starting/Stopping Engine
If engine is operated when temperature is +40_F
(4_C) or higher, remove carburetor heater box
(Fig. 25). However, the heater box must be reinstalled
when temperature falls below +40_F (4_C). To
remove heater box:
1. Pull wire off spark plug and make sure wire does
not contact plug accidentally (Fig. 25).
2. Remove (2) Phillips screws, (2) hex head screws
and (1) lock washer securing heater box in place
(Fig. 25). Pull choke knob off choke rod
(Fig. 21).
3. Lift heater box up and away from the engine,
and reinstall choke knob on mounting pin.
Starting
IMPORTANT: Make sure auger, impeller,
and discharge chute contain no obstructions
before operating unit. USE A STICK, NOT
YOUR HAND, TO REMOVE ANY
OBSTRUCTIONS.
1. Place spark plug wire on spark plug (Fig. 25).
2. Move throttle (Fig. 21) to FAST
position.
3. Ensure that auger/impeller control lever and
traction control lever are in disengaged position
(Fig. 20).
4. Open fuel shut–off valve below fuel tank
(Fig. 22).
5. Rotate choke (Fig. 21) to ON
position.
6. Rotate ignition key (Fig. 20) to ON
position.
7. Cover hole in center of primer (Fig. 21) with
thumb and push primer slowly three times. DO
NOT PRIME IF THE ENGINE HAS BEEN
RUNNING AND IS HOT.
Note: Excessive priming may cause flooding
of engine and failure to start.
8. Grasp recoil starter handle (Fig. 23) and pull it
out slowly until positive engagement results;
then pull vigorously to start the engine. Keep
firm grip on starter handle and return the rope
slowly.
Note: If engine does not start or if
temperature is –10_F (–23_C) or
below, additional priming may be
required. After each additional prime,
try to start the engine before priming
again.
9. After engine starts, immediately rotate choke
(Fig. 21) to 3/4 position. As engine warms up,
rotate choke to 1/2 position; then to OFF
position. If engine falters, return choke to 1/2
position. When engine warms sufficiently, rotate
choke to OFF
position.
10. Move speed selector (Fig. 20) to first gear,
squeeze traction control lever to handgrip, and
then release the traction control lever. If the unit
moves forward (walks) before engaging traction
control lever or after releasing lever, see
Adjusting Traction Drive, page 20.
11. Make sure that auger and impeller are not
rotating when auger/impeller control lever is
disengaged. While standing in the operator
position behind the handles, look around to the
side of the auger housing (Fig. 26). If the auger
and impeller are rotating, a large screw head on
the side of the auger housing will be rotating
(Fig. 26). If the auger and impeller are
rotating when the the engine is running and
the auger/impeller control lever is not
engaged, immediately stop the unit. Refer to
Adjusting Auger/Impeller Drive Belt, page 17. If
the problem persists, bring unit to an Authorized
Toro Service Dealer for repair.
IMPORTANT: Do not operate unit if auger
and impeller rotate when auger/impeller
control lever is not engaged.
