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 11. 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. 19) on control panel
to the R
(REVERSE) position.

3.
Remove cotter pin and washer. Pull speed
selector rod out of hole in speed selector arm
(Fig. 6).
4.
Adjust unit's forward speed by rotating speed
selector rod in trunnion (Fig. 7). 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.
Storage
1.
PREPARE THE FUEL SYSTEM:
Add Toro Stabilizer/Conditioner to the fuel tank
(one ounce per gallon of fuel).
Run engine for five minutes to distribute
conditioned fuel through fuel system.
Stop engine, allow it to cool, and drain fuel tank
or run engine until it stops.
Restart the engine again and run it until it stops.
Either choke or prime the engine, restart it a
third time and run engine until it will not restart.
Dispose of fuel properly. Recycle per local
codes.
DO NOT store STABILIZED gasoline over 90
days.
