Servicing the HS1336iAS Snow Blower

HS1336iAS Snow BlowerIt may be a hybrid, but the HS1336iAS snow blower is as easy to service as any other piece of Honda outdoor equipment. Here’s everything you need to know about keeping this two-stage blower running from adjusting the tracks to changing the oil.

10 and 12 mm box wrench
10 and 14 mm open end wrench
Two 12 and 17 mm open end wrenches

Maintenance Schedule

Each Use: Check engine oil, skid shoes, scraper, shear bolts, and battery electrolyte level.
Each year before use: Change the engine oil. Check the gear reduction oil, spark plug, and tracks.
Every year before storing: Drain the fuel tank and carburetor. Clean the sediment cup. Apply oil to unpainted parts to prevent corrosion.
First month or 20 hours of operation: Change the engine oil and check the tracks.
Every 100 hours: Change the engine oil.
Every four years or 300 hours: Replace the spark plug.

Honda recommends having this snow blower serviced professionally before storage, after the first month or 20 hours of operation and every 300 hours. These services include repairs that are too complex for most owners.

Auger wear will vary depending on the surfaces you operate on. The blades at the end of the auger have wear marks. If the blades are worn down to these marks, the auger should be replaced by a mechanic.

Engine Oil

The dipstick is located on the right side of the snow blower next to the tracks. When checking the oil level, do not screw the dipstick into the hole.

To change the oil, place a drain pan on the right track. Remove the dipstick and unscrew the 10 mm drain bolt directly below the filler neck. Once the crankcase is empty, reinstall the drain bolt, using a new washer.

Honda recommends 5W30 motor oil that meets API service category SJ or later. The oil level should come up to the edge of the filler neck. The iGX390 holds 1.16 quarts.

Spark Plug

The plug is behind the muffler. The plug gap should be between 0.028 and 0.031 inches or 0.7-0.8 mm.

Track Adjustment

The tracks must be clean and dry to get accurate measurements. To check the tension, push down on the top middle section of the track with 22 lb-ft. of force. The track should deflect 0.62-0.79 inches (16-20 mm.)

To adjust the track tension, loosen the lock nut on the tension bolt, located just behind the front wheel. Turn the adjusting nut until the track tension is correct, then tighten the lock nut.

Shear Bolt Replacement

1. Turn the auger clutch switch to “Off.”
2. Release the drive clutch lever.
3. Set the auger to its lowest position.
4. Turn the engine off and remove the key. Let the snowblower come to a complete stop.
5. Look over the snow blower for signs of debris or damage that may have caused the bolt to break.
6. Remove the broken bolts and replace them with new shear bolts and lock nuts.

Batteries and Fuses

To access the batteries, loosen the two knobs on the sides of the rear cover. Rotate the rear cover down and slide it off of the snow blower. The fuses are inside a box directly above the batteries.

The electrolyte level should be between the “Lower Level” and “Upper Level” marks on the side of the battery case. If the level is low, remove the caps from the top of the battery and add distilled water. Clean any corrosion on the battery terminals with baking soda and water.

To remove the batteries, disconnect the negative cable from the left battery, followed by the positive terminal on the right battery. Loosen the nuts holding the battery clamp, then disconnect the joint cable from the left battery’s positive terminal, then the right battery’s negative terminal. Remove the batteries from the snow blower. When reinstalling the batteries, connect them in the reverse order you disconnected them.

Charge the batteries individually. The output of each battery should be within 10% of 35 Ah. Charge the battery at 3.5 amps for 5-10 hours.

Servicing Honda Single Stage Snow Blowers

Honda Single Stage SnowblowerDo you want to make sure your Honda single stage snow blower will be reliable and deliver maximum performance? Here’s everything you need to do to keep your HS720AM, HS720AS or HS720AA performing at its best.

Maintenance Schedule

Before use: Check the oil and scraper blade.
Every year before use: Change the oil. Inspect the spark plug, auger clutch, auger paddles and chute guide lever (if equipped.)
Every year before storage: Check the spark plug and drain the fuel tank and carburetor. Grease the chute tension bolts if you have an AM blower.
After the first 5 hours of use and every 50 hours of operation: Change the oil.
Every 100 hours: Check the spark plug.
Every 150 hours: Replace the spark plug.

Honda recommends having the snow blower professionally serviced every 100 hours to check engine speed and valve clearance, and every two years to inspect the fuel system.

Oil

Oil should be checked with the dipstick inserted in the filler neck but not screwed in. Honda recommends 5W30 oil when temperatures are above 10°F and 5W20 when operating in weather below 10°F.

1. Place the snow blower on a level surface.
2. Place a drain pan between the wheels.
3. Remove the dipstick.
4. Remove the drain bolt and washer from the back of the engine, next to the filler neck.
5. Install the drain plug, using a new washer.
6. Add oil through the filler neck. Stop when the oil is at the edge of the neck.
7. Install the dipstick.

Spark Plug

Let the engine cool off before removing the spark plug.

1. Open the plug access panel next to the fuel filler cap. Disconnect the spark plug cap, then unscrew the plug using a spark plug wrench.
2. Replace the plug if it’s heavily worn or has cracks or other damage. Set the gap to 0.028-0.031 inches.
3. Screw the plug in by hand, then tighten it down with the wrench. If the plug is new, rotate the plug a half turn after it seats to crush the sealing washer. Honda recommends torquing the plug to 14 ft-lbs. if you have a torque wrench on hand.
4. Snap the access panel back into place.

Clutch Lever and Belt Tension

To check the tension, squeeze the bail until you feel some resistance. Measure the distance between the bail and the handle: it should be between 7 ½ and 8 inches.

There are several adjustment holes for both the clutch spring and the cable near the base of the handle. Slide the cover up to expose the spring and access these holes. Moving the spring down one hole adjusts the lever distance by ¼ inch, and adjusting the cable position moves it by 3/8 inch.

To check the belt tension, slide the spring cover up on the drive cable. Engage the auger clutch bail. The spring should be 2.93-3.15 inches long. To adjust the tension, move the cable end from the lower hole to the upper hole on the bail.

Auger Paddle

To inspect the paddles, place the snow blower on a level surface. Disconnect the spark plug and turn the fuel valve off to prevent an accidental start. Measure the distance between the edge of the paddle and the metal part of the auger. If the distance is less than 5/8 inch, have the paddles replaced by a dealer.

Scraper Blade

To check the blade alignment, place the snow blower on a level surface. Disconnect the spark plug and turn the fuel valve off to prevent an accidental start.

The blade should be level and come in contact with the ground. The distance between the lower rubber paddle and the ground should be 1/16-1/8 of an inch. If the blade is uneven or the paddle is too high, adjust the blade. If the blade is less than 1/16” thick, replace it.

To adjust the blade, tilt the snow blower forward. Loosen the three flange nuts and move the blade. Tighten the nuts and recheck the clearance.

If the blade needs to be replaced, simply remove the nuts, washers and carriage bolts, then remove the old blade. Install the new blade, reusing the fasteners. Check the blade adjustment.

Chute Guide Cable (A and AS models)

Pull the chute control lever rearward. The chute should point up with the top of the deflector lining up with the back of the chute. Push the lever down. The deflector should be pointed up just slightly.

If the deflector isn’t moving through its full range of motion, loosen the lock nut on the end of the cable next to the deflector. Turn the adjusting nut below it to change the cable tension, then tighten the lock nut, torquing it to 48-83 in-lbs.
