WARNING

Fire and explosion hazard

Gasoline is highly flammable and its vapors are explosive. Fumes may travel to a distant ignition source and an explosion and/or fire may result.

Handle gasoline carefully. Never store the unit, with fuel in the tank, indoors or in a poorly ventilated enclosure where fuel fumes could reach an open flame, spark, pilot light, such as a furnace, water heater, or clothes dryer.

• Thoroughly clean the unit.
- Lubricate all lubrication points (see Maintenance section).
- Make sure all nuts, bolts, and screws are securely fastened. Inspect all visible moving parts for damage, breakage, and wear. Replace if necessary.
- Touch up all rusted or chipped paint surfaces; sand lightly before painting.
- Cover the bare metal parts of the snowthrower housing auger, and the impeller with rust preventative.
- If possible, store your unit indoors and cover it to give protection from dust and dirt.
- If the machine must be stored outdoors, cover with a heavy tarpaulin.

To Return to Service:

• Fill the fuel tank with a fresh fuel.
  • Make sure all fasteners are tight.
• Make sure all guards, shields, and covers are in place.

Every 50 Hours or Annually

• Check muffler and spark arrester (if equipped)• Check tire pressure

Engine Maintenance

For engine maintenance schedules and procedures, please refer to the engine operator's manual.

Control Lever Linkage Lubrication

WARNING

Amputation hazard

It is critical for safe operation of the unit that the controls disengage when released. Under no circumstances should the unit be used if the controls do not function properly. See Safety Systems Tests to confirm correct operation.

Lubricate the unit at the locations show in Figure 8. Where an oil can is pictured, lubricate with engine oil. Where a grease gun is pictured, lubricate with lithium grease.

Auger Assembly Lubrication

Lubricate Auger Gear Box

The auger gear box is lubricated at the factory and should not require additional lubrication. If for some reason the lubricant should leak out, or if the auger gear box has been serviced, add Lubriplate GR132 Grease or equivalent. Maximum 3-1/4 ounces, (92 grams) should be used.

Remove filler plug (A, Figure 9), once a year to check grease level. If grease is visible, do not add. If grease is not visible, use a piece of fine wire, like a dipstick to check if there is grease in the gear box.

Lubricate Auger Shaft Fittings

Using a grease gun, lubricate the auger shaft fittings (B, Figure 9) every 25 operating hours, or once per season. Each time a shear bolt or pin (C) is replaced, the auger shaft MUST be greased.

For storage or when replacing shear bolts or pins, remove the shear bolts or pins (C), lubricate the shaft fittings (B), and rotate the augers several times to distribute the grease. Reinstall the shear bolts or pins when complete.

Discharge Chute and Deflector Lubricati

Lubricate the chute rotation gear (Figure 10) with grease, and the deflector mechanism with automotive type oil every twenty five operating hours.

Where an oil can is pictured, lubricate with engine oil. Where a grease gun is pictured, lubricate with lithium grease.

Hex Shaft and Chain Lubrication

The hex shaft and drive chains must be lubricated at the interval specified in the Maintenance Chart. Please have your authorized dealer perform this maintenance.

Traction Cable Inspection

The cables are adjusted at the factory and no adjustment should be necessary. However, if the cables have become stretched or are sagging, adjustment will be necessary. Please see your dealer for this adjustment.

Traction Drive Belt Adjustment

The traction drive belt is under constant spring tension and does not require any adjustment. If the traction drive belt is slipping, see your authorized dealer.

Speed Control Rod Adjustment

If the speed control rod requires adjustment, see an authorized dealer.

Auger Cable Adjustment

WARNING

Amputation hazard

Over-tighten the auger cable may cause the auger drive to engage without depressing the auger drive control.

Follow the adjustment procedure to ensure the cable is not over-tightened.

1. With the auger control lever released, the hook (A, Figure 11) should barely touch the lever (B) without raising it. There can be a maximum of 1/32'' (0.8 mm) clearance.
2. To adjust, loosen the nut (C) by holding the adjusting flats (D) and turning the nut. Then, turn the adjusting flats and hold the adjustment screw (E). The adjustment screw is a Phillips screw and the head can be held or turned by inserting a screwdriver through the spring (F).
3. Hold the adjusting flats and tighten the nut.
4. To ensure that the auger does not engage unless the control is fully depressed, please perform the Safety System Tests. The auger must stop within 5 seconds of the control being released.

Shear Pin Replacement

Augers are secured to the auger shaft with special pins that are designed to break if an object becomes lodged in the auger housing. Use only factory spec, or equivalent, shear pins.

1. Turn off the engine and wait for all moving parts to stop.

2. Remove the existing shear pin.

3. Lubricate the auger grease fittings and rotate the auger to lubricate
4. Align the shear pin holes. Install the new shear pin (A, Figure 12) shaft (C). Secure with a cotter pin (B).

Checking Tire Pressure

Tire pressure should be checked periodically. Recommended tire pressure varies through a proper good rule of thumb is to inflate the tire up to, but not exc Inflation" stamped on the side-wall of the tire.

The Ground Truth image displays a single, continuous horizontal line, which is a stylistic or background element (like a ruled paper line). According to Rule 2, such lines must be ignored by the OCR result. The provided OCR content is "____", which consists of underscores. Underscores are not equivalent to a solid line and are not permitted under the “Stylistic/Background Lines (Ignore)” rule. Outputting underscores for a stylistic line is incorrect because it misinterprets the line as a fill-in-the-blank placeholder. Therefore, the OCR result is inconsistent with the Ground Truth.
