Service and Adjustments, Cleaning | Poulan PO8527ESA instruction

MAINTENANCE

MUFFLER

Inspect and replace corroded mufﬂer as it could create a ﬁre hazard and/or damage.

SPARK PLUG

Replace spark plug at the beginning of each season or after every 100 hours of operation, whichever occurs ﬁ rst. Spark plug type and gap setting are shown in the “PRODUCT SPECIFICATIONS” section of this manual.

CLEANING

IMPORTANT: For best performance, keep snow thrower

housing free of any dirt or trash. Clean the outside of your snow thrower after each use.

WARNING: Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

•Keep ﬁnished surfaces/wheels free of gasoline, oil, etc.

•We do not recommend using a garden hose to clean your snow thrower unless the electrical system, mufﬂer and carburetor are covered to keep water out. Water in engine can result in shortened engine life.

SERVICE AND ADJUSTMENTS

WARNING: To avoid serious injury, before performing any service or adjustments:

1.Be sure throttle is in STOP position.

2.Remove safety ignition key.

3.Make sure the augers and all moving parts have completely stopped.

4.Disconnect spark plug wire from spark plug and place wire where it cannot contact plug.

SNOW THROWER

TO ADJUST SNOW THROWER HEIGHT

See “TO ADJUST SKID PLATES” and “SCRAPER BAR” in the Operation section of this manual.

CHUTE DEFLECTOR

The chute deﬂ ector, attached to the top of the discharge chute, is provided to direct discharging snow away from the operator. If the deﬂ ector becomes damaged, it should be replaced.

WARNING: To avoid serious injury, never operate your snow thrower with the deﬂector removed or damaged.

•To change direction and/or distance snow is discharged, see “TO CONTROL SNOW DISCHARGE” in the Op- eration section of this manual.

SHEAR BOLTS (See Fig. 21)

AUGER SHEAR BOLTS

Both right and left-hand augers are secured to the auger shaft with a shoulder/shear bolt and hex nut. Should a for- eign object or ice become lodged in the augers, the shear bolts are designed to break, preventing damage to any other components. If one or both augers do not turn when auger control lever is engaged, check to see if one or both of the bolts have sheared. To replace the shear bolts:

1.Disengage all controls and move throttle control to STOP position. Wait for all moving parts to stop.

2.Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

3.Align hole in auger hub with hole in auger shaft and install a new 1/4-20 x 2" shoulder/shear bolt. Install 1/4-20 lock nut and tighten securely.

CAUTION: Do not substitute. Use only original equipment shear bolts as supplied with your snow thrower.

IMPELLER SHEAR BOLTS

The impeller is secured to the impeller shaft with two (2) capscrew/shear bolts and hex nuts. Should a foreign object or ice become lodged in the impeller, the capscrews are designed to break, preventing damage to any other com- ponents. If impeller does not turn when auger control lever is engaged, check to see if the capscrews have sheared. To replace the capscrew/shear bolts:

1.Disengage all controls and move throttle control to STOP position. Wait for all moving parts to stop.

2.Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

3.Align holes in impeller hub with holes in impeller shaft and install two (2) new 1/4-20 x 1-5/8" capscrew/shear bolts. Install 1/4-20 locknuts and tighten securely.

CAUTION: Do not substitute. Use only original equipment capscrew/shear bolts as supplied with your snow thrower.

4.Connect spark plug wire to spark plug.
