Draining Gasoline; Lubricating Snowthrower; Changing Crankcase Oil; Auger Gear Box Oil - Toro 38590 Operator's Manual

Draining Gasoline

1. Close fuel shut-off valve located under fuel tank
(Fig. 15).
POTENTIAL HAZARD
Gasoline is highly flammable.
WHAT CAN HAPPEN
Gasoline can be ignited and cause serious
personal injury.
HOW TO AVOID THE HAZARD
Drain gasoline outdoors.
Drain gasoline from a cold engine only.
Wipe up any gasoline that may have
spilled.
Do not drain gasoline near any open flame
or where gasoline fumes may be ignited by
a spark.
DO NOT SMOKE a cigar, cigarette or pipe
when handling gasoline.
2. Place a clean drain pan under shut-off valve.
3. Loosen hose clamps securing fuel line to valve
and slide line off valve (Fig. 15).
4. Open valve allowing fuel to flow into drain pan.
5. Reinstall fuel line and secure with hose clamp.

Lubricating Snowthrower

1. Annually lubricate drive chain with chain
lubricant (Fig. 24). Wipe up any excess oil.

Changing Crankcase Oil

Initially, change oil after the first 2 hours of engine
operation; thereafter, change oil after every 25 hours
of engine operation or annually. If possible, run
engine just before changing oil because warm oil
flows better and carries more contaminants than cold
oil.
1. Pull wire off spark plug and make sure wire does
not contact plug accidentally.
2. Clean area around oil drain cap. Next, slide oil
drain pan below drain extension; then remove oil
drain cap (Fig. 25).
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.
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
