3.
After all oil is drained, reinstall oil drain cap
securely.
4.
Position snowthrower on a level surface. Next,
fill crankcase with oil: see Fill Crankcase With
Oil, page 10. Wipe up any oil that may have
spilled.
Auger Gear Box Oil
The auger gear box oil level must be checked at
setup, after every 10 hours of use, and upon removal
from annual storage. To check the auger gear box oil
level:
1.
Position snowthrower on a level surface.
2.
Clean area around pipe plug so dirt is removed.
3.
Remove pipe plug from gear box (Fig. 11).
4.
Check level of oil in gear box. Oil must be at
point of overflowing in filler opening.
5.
If level of oil is low, add GL–5 or GL–6 SAE
85–95 EP transmission oil to the gear box until
point of overflow.
Note:
Do not use synthetic gear oil.
6.
Reinstall pipe plug in gear box.
Adjusting Auger/Impeller Drive
Belt
If auger/impeller belt slips, resulting in decreased
snowthrowing performance, an adjustment is
required. WHENEVER A NEW BELT IS
INSTALLED, AN ADJUSTMENT IS
REQUIRED. USE ONLY GENUINE TORO
REPLACEMENT PARTS.
1.
Pull wire off spark plug and make sure wire does
not contact plug accidentally.
2.
Remove (3) flange head capscrews securing belt
cover to engine frame and slide belt cover up
cables (Fig. 4).
3.
CHECKING IMPELLER CABLE
ADJUSTMENT—Depress the auger/impeller
control lever on the right hand grip. Hold the
lever and insert a .010” (.25 mm) feeler gauge
between a coil in the center of the spring
(Fig. 24). Adjust the cable to achieve .010” (.25
mm) gap between the coils.
4.
Loosen upper jam nut securing auger/impeller
cable to mounting bracket (Fig. 25).
5.
Rotate bottom jam nut upward to increase belt
tension.
6.
Tighten upper jam nut against bracket.
7.
Recheck idler adjustment: refer to step 3
8.
Check impeller brake arm clearance by releasing
the auger/impeller lever. With the lever released,
there should be more than 1/8” clearance
between tab on impeller idler arm and brake arm
(Fig. 26). If there is less than 1/8” clearance,
belt must be replaced.
POTENTIAL HAZARD
•
Improper adjustment may cause injury if
auger/impeller turns when disengaged.
WHAT CAN HAPPEN
•
Rotating impeller or auger can cut off or
injure fingers or hands.
HOW TO AVOID THE HAZARD
•
Keep face, hands, feet and any other part of
your body or clothing away from
concealed, moving or rotating parts.
•
Make certain that impeller brake arm
clearance is maintained.
•
Do not adjust the auger/impeller drive belt
too tight because it may cause the
auger/impeller to turn when the control
lever is in the disengaged position. If this
occurs, decrease belt tension.
9.
Reinstall belt cover and cable cover.
10. Check tension of belt by operating the auger. If
belt still slips, replace the belt.
