A. Drive Control Handle Shave Plate (not shown) Located on the right side of the upper handle, the Drive Control is used to engage and disengage the drive wheels. Squeeze the Drive Control handle against the upper handle to engage the wheels; release to disengage. B. Speed Control Lever The Shave Plate maintains contact with pavement as the snow thrower is propelled, allowing snow close to pavement's surface to be discharged.
2. Attach the chute rotation bar to the mount bracket onto the chute housing using two hex screws, washers and locknuts. Tighten fasteners securely. NOTICE: Make sure all fasteners are tightened before starting the machine. 3. Slide the upper chute crank rod through the mounting hole under the control panel and into the lower chute crank rod. 2. Attached the upper handle to the lower handle using four (4) knobs, washers and bolts. Handle Assembly 1. Attach the lower handles using four (4) bolts.
NOTICE: Do not bend or kink the control cables. The cables should be routed under the handle assembly and not wrapped around the handle or knobs. The cables must move freely and not bind. 3. Secure the speed control cables to the handle with provided clips. Note: Do not secure the auger or drive control cables with the clips. Skid Shoe Installation and Adjustment 1. Locate the pair of skid shoes from parts bag and remove the bolts. 2.
4. Place a spacer board on the ground underneath the auger shave plate between the skid shoes. The thickness of the board should be the same as the height above the ground you wish to raise the auger shave plate. The skid shoes should not touch the board. 5. With the two (2) nuts loose allow the skid shoe to slide to the ground then tighten the nuts to secure the skid shoe. OPERATION PLEASE REFER TO ENGINE MANUAL (SEPARATE DOCUMENT) FOR ENGINE OPERATION INSTRUCTIONS.
Auger and Drive Controls Drive Speed Control Lever 1. To engage the auger, press down on the auger control handle (left side handle). Move the drive speed control lever to the desired speed. There are six (6) settings: four (4) forward speeds and two (2) reverse speeds. 1 is the slowest forward speed and 4 is the fastest forward speed. R1 is the slowest reverse speed and R2 is the fastest reverse speed. 2. To engage the drive, press down on the drive control handle (right side handle).
Chute Discharge Angle Adjustment WARNING! Always disengage the drive and auger control handles before making adjustments. Make sure the augers are stopped and the machine is not moving. The angle of the chute deflector controls the discharge distance of the snow. Raising the angle will increase the distance. Lowering the angle will decrease the distance. Adjust the chute outlet to the desired direction. Turn the chute rotation handle clockwise or counter-clockwise until the desired position is reached.
2. Stop the auger by releasing the left control handle. 3. Set the engine switch to the OFF position. See ENGINE manual for stopping procedures. 4. Remove snow from all Snow Thrower surfaces including the auger housing and chute areas. Clearing Restrictions If the snow discharge chute or auger housing becomes clogged STOP the engine, and make sure that all rotating parts have come to a complete stop. Remove the spark plug cap from the spark plug.
Auger or Impeller Jams WARNING! The auger and impeller rotate at fast speeds which can cause harm or even amputation to a person's body parts. Even if you do not see the auger or impeller rotating, it may start at any time if the engine is running. The chute clean-out tool is fastened to the top of the auger housing with a mounting clip and a cable tie at the factory. Cut the cable tie before operating the snow thrower. 1. Always turn OFF the engine before attempting to clear any clogs or jams. 2.
Note: The upper cable end must be in the upper single center hole of the adjustment plate. Do not change the position of the upper cable. 3. Slide up the slip cover to access the adjustment plate. 5. Connect the upper cable to the control handle. 6. Start the engine and engage the drive control handle to test the operation of the drive engagement. Note: With the drive control handle at the full released position, the cable should be barely tight.
1. With the engine running engage the drive control handle and move the speed control lever between F1 and R1 to determine which way the cables need to be adjusted. Release the drive control handle when shifting between gears. 2. Loosen the jam nuts on each cable (only one or two threads) and move each cable up and down as required until a positive direction change is achieved when the lever is shifted between F1 and R1. This may take multiple attempts to find the exact setting. 3.
(1 to 9). Only move the lower cable diagonally one hole at a time from its original position. Note: The upper cable end must be in the upper single center hole of the adjustment plate. Do not change the position of the upper cable. 1 2 3 4 5 6 – – – – – – Upper Auger Cable (Always in upper center hole) Adjustment Plate lower Auger Cable Cable Pulley Adjustment Plate Lower Cable Opening Slip Cover 1.
