Operating
Operate Safely
ˇ Inspect machine before you operate. Be sure hardware is tight. Repair or replace damaged, badly worn, or missing parts. Be sure guards and shields are in good condition and fastened in place. Make any necessary adjustments before you operate.
ˇ Clear work area of objects that might be thrown. Keep people and pets out of the work area. Stop machine if anyone enters the area.
ˇ If you hit an object, stop the machine and inspect it. Make repairs before you operate. Keep machine properly maintained and in good working order. Keep all shields and guards in place.
ˇ DO NOT blow snow toward people, cars, or buildings.
ˇ DO NOT use snowblower on surfaces above ground level, such as, a roof of a building.
ˇ Be extremely careful if you must clear snow from a gravel path. Be aware that snowblower may pick up gravel in snow. Adjust spout angle carefully to blow this snow safely.
ˇ DO NOT leave machine unattended when it is running.
ˇ Only operate during daylight or with good artificial light.
ˇ Be sure of footing. Operate slowly on slippery surfaces. Be especially careful when you pull machine backwards with the engine running.
ˇ DO NOT blow snow across a slope. Be careful when you change direction on a slope. Do not try to clear snow from steep slopes. Keep away from edge of a ditch or bank.
ˇ Keep a firm hold on the machine handles. Avoid sudden starts and stops.
ˇ DO NOT run engine in a building unless there is good ventilation.
Rotating Blades Are Dangerous - Protect Children And Prevent Accidents
ˇ Never assume that children will remain where you last saw them. Children are attracted to blowing snow, stay alert to the presence of children.
ˇ Keep children in the house when you are operating the machine.
ˇ Turn machine off if a child enters the area.
ˇ Use extra care when you come to blind corners, shrubs, trees, or other objects that may block your vision.
ˇ DO NOT let children or an untrained person operate the machine.
HELP PREVENT SERIOUS OR FATAL ACCIDENTS:
ˇ Be alert at all times, people ESPECIALLY CHILDREN can move quickly into the area before you know it.
ˇ Shut off auger when you are not blowing snow.
ˇ and clothing away from moving parts.
Wear Appropriate Clothing
ˇ Wear close fitting clothing and safety equipment appropriate for the job.
ˇ Loud noise can cause impairment or loss of hearing, wear a suitable protective device such as earplugs.
Adjusting Scraper Blade
1. Park snowblower on a hard, smooth surface.
2. Stop engine, remove key, wait for all moving parts to stop.
3. Remove wire from spark plug to prevent accidental starting.
4. Tip unit back onto handle bars and support housing.
5. Adjust skid shoes to their FULL UP position.
ˇ If scraper blade has excessive wear, replace it.
ˇ If scraper blade can be adjusted; loosen nuts and reposition scraper blade, flush with skid shoes.
ˇ Adjust skid shoes to the proper height. (See Adjusting Skid Shoes in this section).
Adjusting Skid Shoes
Adjust skid shoe height for proper working conditions:
ˇ To operate on a smooth, hard surface: Adjust skid shoes so there is 3mm (1/8 in.) between scraper blade and surface.
ˇ To operate on gravel or uneven surface: Adjust skid shoes so there is 30mm (1-1/4 in.) between scraper blade and surface.
ˇ To operate on hard packed snow: Remove skid shoes and install them upside down. This will prevent the snowblower from riding up on the snow. Adjust skid shoes so there is 3mm (1/8 in.) between scraper blade and surface.
1. Park snowblower on a hard, smooth surface.
2. Stop engine, remove key, wait for all moving parts to stop.
3. Remove wire from spark plug to prevent accidental starting.
ˇ Air pressure in both tires should be equal, although some machine leveling can be made by using different pressures. Check for a maximum of 165 kPa (24 psi) in each tire.
ˇ Each tire must be resting on hard surface, not a cross-link of tire chain.
5. Put a block under auger housing.
ˇ If skid shoes have excessive wear, replace them.
ˇ If skid shoes can be adjusted; loosen two nuts (A) and move skid shoe (B) to desired position.
7. Tighten nuts. Adjust other skid shoe to the same height.
Using Drive Control Levers
ˇ Pull lever (A) to handle to ENGAGE the traction drive.
ˇ Release lever to DISENGAGE traction drive.
ˇ Traction drive lever (A) works independently from the auger drive lever (B).
ˇ If unit does not respond, is slow to respond or engages too aggressively when the traction drive lever is engaged, see Adjusting Traction Drive Clutch in the Service section.
ˇ Pull lever (B) to handle to ENGAGE the auger drive.
ˇ Release lever to DISENGAGE auger drive.
ˇ Auger drive lever (B) works independently from the traction drive lever (A).
ˇ If auger is not throwing snow very well or it feels like the auger drive belt is slipping when the auger drive lever is engaged, see Adjusting Auger Drive Belt Tension in the Service section.
ˇ If the auger does not come to a complete STOP in 5 seconds or less after the auger drive lever is released, see Adjusting Impeller / Auger Brake in the Service section.
Using Speed Selector Lever
IMPORTANT: Avoid damage! DO NOT overload machine capacity by attempting to clear snow at too fast a rate. |
The speed selector lever (A) controls the units forward speed and reverse motion:
ˇ Moving the speed selector lever forward increases forward travel. There are six forward speeds available: "1" is the slowest speed and "6" is the fastest speed.
ˇ Moving the speed selector lever rearward increases reverse travel. There are two reverse speeds available: "R1" is the slowest speed and "R2" is the fastest speed.
TO OPERATE SPEED SELECTOR LEVER:
ˇ With engine running, position speed selector lever in the notch of the desired speed and ENGAGE the traction drive lever (B).
ˇ Forward speed can be changed without declutching (releasing traction drive lever).
ˇ DO NOT change motion from forward to reverse with traction drive lever ENGAGED.
ˇ Release traction drive lever to STOP forward or reverse travel.
ˇ Drive wheel slippage will occur as the traction drive disk wears. (See Adjusting Traction Drive Clutch in the Service section.)
Using Discharge Chute Controls
c CAUTION: Avoid injury! ˇ DO NOT put hands or feet near or under rotating parts.
|
The discharge chute control (A) will rotate the discharge chute (B):
ˇ The discharge chute will rotate (full right, straight ahead, or full left).
ˇ If discharge chute is too difficult to rotate or is too loose. (See Adjusting Chute Crank in the Service section.)
The chute deflector lever (C) will assist in positioning the chute deflector (D):
ˇ The chute deflector will determine how high or low snow will be thrown.
ˇ If the chute deflector becomes difficult to move or is too loose. (See Adjusting Chute Deflector in the Service section.)
Pre-Starting Engine
IMPORTANT: Avoid damage! In very cold weather, check impeller to be sure it is not frozen. Starting with a frozen impeller could damage the unit. |
To check unit for a frozen impeller (A):
ˇ Disconnect spark plug wire from spark plug.
If impeller is frozen: Rewind starter can not be pulled. Move unit to a heated area so ice around impeller can thaw.
If Impeller is not frozen: Rewind starter can be pulled - it will be more difficult than normal.
