Anypowerequipmentcancauseinjuryifoperatedimproperlyoriftheuserdoesnotunderstandhowtooperatetheequipment. Exercise caution at all times, when using power equipment.

•Read this owner's manual carefully and know how to operate your snow thrower and how to stop the unit and disengage the controls quickly.

•Never allow children to operate the equipment.

•Never allow adults to operate the equipment without proper instruction.

•Keeptheareaofoperationclearofallpersons,especially small children, and pets.

•Thoroughly inspect the area where the equipment is to be used and remove all door mats, sleds, boards, wires and other foreign objects.

•Disengage all clutches and shift into neutral before starting engine.

•Do not operate equipment without wearing adequate winter outer garments.

•Wear substantial footwear which will protect feet and improve footing on slippery surfaces.

•Checkfuelbeforestartingtheengine.Donotremovethe fuel cap or fill the fuel tank while the engine is running or hot. Do not fill the fuel tank indoors. Gasoline is an extremely flammable fuel.

•Make sure the snow thrower height is adjusted to clear the type surface it will be used on.

•Do not use the snow thrower without the rear weight attached to the tractor.

•Never make any adjustments while the engine is running.

•Alwayswearsafetyglassesoreyeshieldduringoperation or while performing adjustment or repair.

•Do not place hands or feet near rotating parts. Keep clear of the discharge opening at all times.

•Use extreme caution when operating on or crossing gravel surfaces.

•Do not carry passengers.

•After striking a foreign object, stop the engine, remove the wire from the spark plug and then thoroughly inspect thesnowthrowerfordamage.Repairanydamagebefore restarting and operating the snow thrower.

•If the snow thrower starts to vibrate abnormally, stop the engine immediately and check for the cause. Vibration is generally a warning of trouble.

•Stop the engine whenever you leave the operating position, before unclogging the snow thrower or making any adjustments or inspections.

•Take all possible precautions when leaving the unit unattended. Disengage the attachment clutch lever or switch, lower the snow thrower, shift into neutral, set the parking brake, stop the engine and remove the key.

•When cleaning, repairing or inspecting, make certain all moving parts have stopped. Disconnect the spark plug wireandkeepitawayfromtheplugtopreventaccidental starting.

•Do not run engine indoors except when transporting the snow thrower in or out of the building. Open the outside doors. Exhaust fumes are dangerous.

•Do not clear snow across the face of slopes. Exercise extreme caution when changing direction on slopes. Do not attempt to clear steep slopes. Refer to the slope guide on page 79 of this manual.

•Never operate the snow thrower without guards, plates or other safety protection devices in place.

•Never operate the snow thrower near glass enclosures, automobiles, window wells, drop offs etc.without proper adjustment of the snow thrower discharge angle.

•Never direct discharge at bystanders or allow anyone in front of the snow thrower.

•Never run the snow thrower into material at high speeds.

•Do not overload the machine capacity by attempting to clear snow at too fast a rate.

•Never operate the machine at high transport speed on slippery surfaces. Look behind and use care when backing up.

•Watchfortrafficandstayalertwhencrossingoroperating near roadways.

•Disengagepowertothesnowthrowerwhentransporting or when not in use.

•Use only attachments and accessories approved by the manufacturer of the snow thrower (such as wheel weights, counter weights, cabs etc.)

STEP 47: (SEE FIGURE 46)

•Assemble the drive belt onto the engine pulley and then onto the large pulley on top of the clutch/idler assembly.The belt must be placed to the inside of the idler pulley and the keeper bolt located beside the large pulley.

•Place tension on the belt by pulling the left side tensioning chain out as far as the 3/32" hairpin cotter

(FF)will allow. Secure the chain in this position by inserting a 1/8" hairpin cotter (EE) through the chain.

IMPORTANT: Do Not assemble the "V" belt around the outside of the engine pulley keeper or the keeper bolt.

ASSEMBLY OF THE SNOW THROWER

STEP 48: (SEE FIGURE 47)

•Place the lift handle into the lift bracket on the right side of the snow thrower. Fasten the handle to the bracket using two 5/16" x 1-3/4" hex bolts (B) and 5/16" Nylock nuts (Y).

NOTE: Be sure the lift release cable's plastic covering stays inserted into the trigger assembly for the next step.

STEP 49: (SEE FIGURE 48)

•Push the lift handle down into the locked position. Insert the end of the cable wire into the hole in the lift rod. Place the threaded fitting into the slot in the lift bracket, with one hex nut above and one hex nut and the lock washer below the slot.Tighten the nuts, adjusting them to eliminate slack in the cable wire.

Refer also to the Service and Adjustments section on page 28 in this manual.

HINT: For easier assembly of the lift release cable, tilt the snow thrower forward onto the spiral auger.

STEP 50: (SEE FIGURE 49)

•Tilt the snow thrower back down to the ground.

•Remove the nylon tie which fastens the auger drive belt to the discharge housing, leaving the belt assembled around the pulleys.

•Remove the nylon tie which fastens the chute crank rod to the crank rod support tube.

•Assemble the crank rod support tube to the bracket on the left side of the discharge housing using two 5/16" x 1-1/4" carriage bolts (I), and 5/16" Nylock nuts

(Y).

STEP 52: (SEE FIGURE 51)

•Attach the chute crank rod assembly brackets to the plastic bracket on the left side of the discharge housing. Align the chute crank bracket beneath the rod support bracket and assemble both to the plastic bracket using two 5/16" x 1" carriage bolts (J), 5/16" washers (Q) and 5/16" Nylock nuts (Y). Do not tighten yet.

STEP 53: (SEE FIGURE 52)

•Coat the top of the ring around the discharge opening with general purpose grease.

•Place the discharge chute (facing forward) onto the ring. Place the anti-rotation bracket on top of the chute flange, aligning it with the holes on the right hand side of the flange. Attach the three chute keepers (BB) (right side up as shown) to the bottom of the flange using six 1/4" x 1" hex bolts (D), 1/4" flat washers (P) and 1/4" flanged lock nuts (V). Tighten carefully so that the nuts are snug but do not dig into the plastic chute keepers.

•Place the plastic cap (HH) onto the short end of the anti-rotation bracket.

•Position the crank rod spiral (see figure 51) so that it does not rub against the bottoms of the notches in the chute flange. Tighten the nuts.

•Check if the crank rod rotates the chute freely. If not, loosen by 1/4 turn each of the six hex bolts holding the chute keepers to the chute flange.

•Secure the control cables to the crank rod support tube using a nylon tie (II).

Skip this step if you have a lawn tractor.

This step is for garden tractors only.

•If you have a (GT) Garden Tractor, remove the stop bolts from each side of the snow thrower frame.

ATTACHING SNOW THROWER TO TRACTOR

NOTE: An additional person's help may be required to mount the snow thrower to the front of the tractor.

STEP 55: (SEE FIGURE 54)

•Place the tractor and snow thrower on a flat, level surface so that the tractor can be rolled forward to attach the snow thrower.

•Remove the Attachment Pin from the snow thrower.

•Extend the auger belt out behind the snow thrower, making sure the belt is still looped over the top of the large drive pulley and underneath the two idler pulleys.The "V" side of the belt must be seated in the grooves of all three pulleys.

•Roll the tractor up behind the snow thrower, centering it between the snow thrower's mounting plates.

•Raise the rear of the snow thrower by lifting up on the lift handle until the notches in the mounting plates align with the shoulder bolts in the tractor's side plates. Guide the bolts into the notches.

•To ease the assembly of the auger drive belt, delay the installation of the attachment pin until you have assembled the belt as instructed in steps 56 and 57.

BEFORE INSTALLING THE AUGER BELT

STEP 56: (SEE FIGURE 55)

•The auger belt comes preassembled to the pulleys on the snow thrower housing. Make sure the belt passes over the top of the auger pulley and then twists 1/4 turn to pass underneath each side idler pulley.The "V" side of the belt must mate with the grooves of the pulleys.

INSTALLING THE AUGER BELT

STEP 57: (SEE FIGURE 56)

•Push the lift handle down to increase slack in the belt (attachment pin must first be removed).

•Swing the idler arm over to the left side.

•Place the auger belt around the rear pulley and between the two pulleys on the idler arm.The "V" side of the belt must be seated in the grooves of the v- pulleys.
