SLOPE OPERATION

WARNING

Never operate on slopes greater than 17.6 percent (10°) which is a rise of 3-1/2 feet (106 cm) vertically in 20 feet (607 cm) horizontally.

When operating on slopes use additional wheel weights or counterweights. See your dealer to determine which weights are available and appropriate for your unit.

Select slow ground speed before driving onto slope. Travel UP and DOWN the slope, never across the face, use caution when changing directions and DO NOT START OR STOP ON

SLOPE.

Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.

All slopes require extra caution. If you cannot back up the slope or if you feel uneasy on it, do not operate on it.

Do

• See your authorized dealer for recommendations counterweights to improve stability.

• Travel up and down slopes, not across.

• Remove obstacles such as large rocks, tree limbs, etc.

• Watch for holes, ruts, or bumps. Uneven terrain could overturn the unit. Snow can hide obstacles.

• Use slow speed. Tires may lose traction on slopes.

Choose a low gear so that you will not have to stop or shift while on the slope.

• Keep all movement on the slopes slow and gradual.

Do not make sudden changes in speed or direction.

• Always keep unit in gear especially when traveling downhill.

Do Not

• Do not start or stop on a slope. If tires lose traction, disengage the broom and proceed slowly straight down the slope.

• Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.

• Do not operate near drop-offs, ditches, or embankments. The unit could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.

• Do not operate power broom on roof tops.

• Do not operate on wet surfaces. Reduced traction could cause sliding.

• Do not shift to neutral and coast down hills.

Storage

TEMPORARY STORAGE

(30 DAYS OR LESS)

Remember, the fuel tank will still contain some gasoline, so never store the unit indoors or in any other area where fuel vapor could travel to any ignition source. Fuel vapor is also toxic if inhaled, so never store the unit in any structure used for human or animal habitation.

Here is a checklist of things to do when storing your unit temporarily or in between uses:

• Keep in an area away from where children may come into contact with it. If there’s any chance of unauthorized use, remove the spark plug wire.

• If the unit can’t be stored on a reasonable level surface, chock the wheels.

• Clean all debris and snow from the unit.

NOTE: If storing your unit between winter snow removal jobs in a cold area, we suggest that you fill the fuel tank at the completion of each job to prevent water condensation in the fuel tank. Wait for engine to cool before filling tank.

LONG TERM STORAGE

(LONGER THAN 30 DAYS)

Before you store your unit for the off-season, read the

Maintenance and Storage instructions in the Safety Rules section, then perform the following steps:

1. Drain crankcase oil and refill with a grade of oil that will be required when unit is used again.

2. Coat all bare metal surfaces with paint or light coat of oil to prevent rusting.

3. Clean external surfaces and engine.

4. Prepare engine for storage. See engine owner’s manual.

5. Clean any dirt from the engine housing.

6. Cover air intake and exhaust outlet tightly with plastic or other waterproof material to keep out moisture, dirt and insects.

7. Completely grease and oil as outlined in the Normal

Care section.

WARNING

Never store the unit, with gasoline in engine or fuel tank, in a heated shelter or in enclosed, poorly ventilated enclosures. Gasoline fumes may reach an open flame, spark or pilot light (such as a furnace, water heater, clothes dryer, etc.) and cause an explosion.

Handle gasoline carefully. It is highly flammable and careless use could result in serious fire damage to your person or property.

Drain fuel into an approved container outdoors away from open flame or sparks.

8. Drain fuel system completely or add a gasoline stabilizer to the fuel system. If you have chosen to use a fuel stabilizer and have not drained the fuel system, follow all safety instructions and storage precautions in this manual to prevent the possibility of fire from the ignition of gasoline fumes. Remember, gasoline fumes can travel to distant sources of ignition and ignite, causing risk of explosion and fire.

NOTE: Gasoline, if permitted to stand unused for extended periods (30 days or more), may develop gummy deposits which can adversely affect the engine carburetor and cause engine malfunction. To avoid this condition, add a gasoline stabilizer to the fuel tank or drain all fuel from the system before placing unit in storage.

STARTING AFTER

LONG TERM STORAGE

Before starting the unit after it has been stored for a long period of time, perform the following steps.

1. Remove any blocks from under the unit.

2. Unplug the exhaust outlet and air cleaner.

3. Fill the fuel tank with fresh gasoline. See engine manual for recommendations.

4. See engine owner’s manual and follow all instructions for preparing engine after storage.

LUBRICATION

IMPORTANT NOTE

It is very important that grease fittings on the broom shaft are lubricated regularly. If broom rusts to shaft, damage to worm gear may occur if shear pins do not break.

To prevent wheels rusting to axles, it is also necessary to remove the wheels and grease the axles regularly.

1. Apply medium weight (10W) oil to points shown (See

Figures 9-12).

2. Remove wheels and grease axles once each year

(See Figure 11).

3. Apply 5W-50 synthetic motor oil to the friction disk drive hex shaft.

4. Grease broom drive universal joint (See Figure 12).

NOTE: Access is best gained from underneath machine.

5. Grease broom pivot pin (See FIgure 12).

Generally, all moving metal parts should be oiled where contact is made with other parts. Keep oil and grease off belts, pulley grooves, drive disc, and friction disc.

LUBRICATION NOTES:

Grease locations indicated by grease gun symbol. Use grease fittings when present.

Disassemble parts to apply grease to moving parts when grease fittings are not installed.

Limited Warranty

Limited Warranty: Subject to the limitations set forth herein, M-B Companies, Inc. of Wisconsin (“M-B”) warrants its products to be free from defects in material and workmanship for a period six (6) months from the date of delivery of the product to its original owner, except that the warranty is twelve (12) months solely for the following products:

Truck Mounted Pavement Marking Equipment, Wood and Brush Chippers, and Airport Runway Brooms. All other products are covered by the six-month warranty. Parts shall have a ninety (90) day warranty. This warranty is not transferable without the written consent of M-B.

Notice: M-B’s obligations under this Limited Warranty are conditioned on M-B receiving, within the warranty period, written notice from Buyer specifying the nature of any alleged defect and requesting corrective action by Seller.

Remedies: M-B, at its option, will repair or replace, or provide a credit to Buyer for, defective warranted items. If requested by M-B, products or parts for which a warranty claim is made shall be returned, transportation prepaid, to

M-B’s factory. Buyer shall not return any product for repair, replacement or credit without M-B’s advance written consent.

Other Manufacturer’s Warranty: On products furnished by M-B, but manufactured by any other manufacturer, the warranty of said manufacturer, if any, will be assigned to Buyer, if the said warranty is assignable. However, M-B does not represent or guarantee that such manufacturer will comply with any of the terms of the warranty of such manufacturer.

Exclusions: Any improper use, operation beyond capacity, or substitution of parts not approvedby M-B, or alteration or repair by others in such a manner as in M-B’s judgment materially and/or adversely affects the product shall void this warranty. This warranty does not apply to defects caused by damage or unreasonable use while in the possession of the owner, including but not limited to: failure to provide reasonable and necessary maintenance, normal wear, routine tune-ups or adjustments, improper handling or accidents, operation at speed or load conditions contrary to published specifications, improper or insufficient lubrication, or improper storage.

Seller manufactures power brooms that mount to many makes and models of equipment. Seller attempts to ensure that the mounting frames fit correctly. However, the large number of tractor models, types and options currently available, compounded by frequent manufacturer design changes, may prevent Seller from supplying a frame that fits every unit correctly. Therefore, unless Buyer supplies drawings which detail the attachment points on the specific unit to which the broom will be mounted, Seller will not be responsible for the fit of the mounting frame.

The batteries, tires, rubber materials, brushes and material normally consumed in operation, and major components such as engines, air compressors, and hydraulic pumps and motors are excluded from this warranty but may be covered to the extent of any warranty received by M-B from its supplier if permitted by the terms of such warranty.

Limitations of liability: M-B shall not be liable for any incidental, consequential, punitive or special damages of any kind, including, but not limited to, consequential labor costs or transportation charges in connection with the repair or replacement of defective parts, or lost time or lost profits or expense which may have accrued because of said defect.

M-B disclaims all other warranties, whether express or implied, including but not limited to any implied warranty of merchantability or fitness for a particular purpose. This warranty is the exclusive remedy of buyer. This warranty cannot be extended, broadened or changed in any respect except in writing by an authorized officer of M-B.

Notwithstanding anything in this warranty to the contrary, in no event shall M-B’s total liability hereunder exceed the purchased price of the particular product.
