side of the auger housing. 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.
Adjusting Traction Drive
If speed selector shifts properly but snowthrower does
not drive in reverse or forward speeds, an adjustment
may be required.
1. Check adjustment per steps 4 and 5 of Install
Traction Rod, page 8. Make adjustments if
required.
2. If linkage is adjusted correctly and problem
persists, contact your local Authorized Toro
Service Dealer.
Adjusting Speed Selector
If there is slow or no ground speed in No.1 speed
selection, or speed selector cannot be moved into
No. 5 speed selection, an adjustment of the speed
selector linkage is required.
1. Pull wire off spark plug and make sure wire does
not contact plug accidentally (Fig. 25).
2. Move speed selector (Fig. 20) on control panel
to the R
2
(REVERSE) position.
3. Remove cotter pin and washer. Pull speed
selector rod out of hole in speed selector arm
(Fig. 7).
4. Adjust unit’s forward speed by rotating speed
selector rod in trunnion (Fig. 8). Lengthening the
rod makes forward speed faster. Shortening the
rod makes forward speed slower.
5. Reinsert speed selector rod into speed selector
arm and secure with washer and cotter pin.
6. If desired speed hasn’t been achieved, repeat
steps 3-5.
Replacing Spark Plug
Use a Champion RJ–19LM spark plug or equivalent.
Set air gap at 0.030” (0.76 mm). Since air gap
between center and side electrodes of the spark plug
increases gradually during normal engine operation,
install a new plug after every 25 hours of engine
operation.
1. Clean area around spark plug so foreign matter
cannot fall into cylinder when plug is removed.
2. Pull wire off spark plug (Fig. 25) and remove
plug from cylinder head.
IMPORTANT: A cracked, fouled or dirty
spark plug must be replaced. Do not sand
blast, scrape or clean electrodes because grit
may eventually release from the plug and fall
into the cylinder. The result will likely be
engine damage.
3. Set air gap between electrodes of new spark plug
at 0.030” (0.76 mm) (Fig. 38). Next, install
spark plug in cylinder head. Tighten plug to
15 ft–lb (20.4 N
m).
4. Push the wire onto the spark plug.
