Description

2 Description

Fig.3

The side brush is used to collect dirt at borders and to enlarge the working width as well as to increase the area performance on large surfaces.

The cylinder broom casts the debris overhead into the dirt hopper. The collected fine dust is evacuated by the suction fan and separated by a filter system. The air returned into the environment is clean.

Dirt disposal of the Apex 49 is via two dirt hoppers (2x30 litres) which are to be emptied manually.

Dirt disposal of the Apex 49H (Lift-Up

Disposal) is via lift-up disposal

(lift-up height > 1350mm) directly into standard waste containers.

Fig.4

14

Description

The cylinder broom is equipped with

12 rows of bristles arranged in

V-shape.

The cylinder broom width amounts to

27.6 in. (700mm) and its diameter to

13.6 in. (345mm).

2.4 Filter System / Dust

Evacuation

The filter system is located in the filter case above the dirt hopper. The suction fan transports the fine dust raised by the cylinder broom to the plate filter where it is separated. The fine dusts sets at the outsides of the filter blades.

2.6 Steering

Steering is controlled mechanically from steering wheel to front wheel via chain. This chain is to be re-adjusted as required.

At the standard version, the side brush is located at the front right of the machine. The operator lifts and lowers it by hand lever.

The side brush has a light inclination.

The swinging area of the side brush arm is limited by stop screws.

The side brush is driven by V-belt.

In case of heavy dust development, check and clean the plate filter at regular intervals.

For special application, fitting of a second side brush at the left is possible.

Due to normal working vibration the set dust partly falls off into the dirt hoper. To ensure working in a dustfree environment, however, actuate the shaking system regularly, or after request by the pilot lamp at the latest.

- Never leave machine unattended with engine running.

- Never change or alter fuel system unless authorized by Minuteman

International Inc. Service Department.

- Always keep nuts and bolts tightened and hose connection snug.

- Always store propane tank outside in an approved, secured, and tamper proof enclosure to provide safety from vandalism and accidents.

- Never use a non-sweeper listed fuel tank on your propane buffer.

- Always operate your sweeper, with exhaust (muffler) pointed away from merchandise, furniture, etc.

Heat from exhaust may cause damage.

- For all engine repairs refer to the engine manual included with this parts and instruction book.

- Engine will not start if rego coupling is crossed, (fuel line connection) make sure fuel line connection is properly done.

- Always check fuel system for leaks with soapy water. (Hoses, regulators, connections)

- Never smoke while operating or working on sweeper.

- Keep hands, feet, hair, clothing, etc.

away from brushes, pulleys, and any other moving parts on equipment.

- If you smell gas, do not touch any electric switch, extinguish any open flame and contact your gas supplier, and open windows.

- If there is any smell of propane fuel, check immediately for leaks.

- Do not store any other flammable liquids or vapors in the vicinity of propane storage area, machine storage area or any other appliance.

- Do not place flammable objects such as matches, fuel, etc., close to the engine while it is running.

- When parking the machine, immediately close the tapping valve of the cylinders.

- Never attempt to repair a propane fuel tank by yourself. Tanks can only be repaired by a Department of

Transportation authorized facility.

- Check liquid propellant gas systems for proper condition, function and leakage at regular intervals.

- For repairs or adjustments on your

Propane sweeper use only an authorized Minuteman Service Center.

CAUTION

Visible escaping gas vapor is extremely cold (ICE). Degrees (-44) avoid contact.

CAUTION

Propane gas is heavier than air. The gas will settle to the lowest possible area and build upwards.

CAUTION

Build-up of propane vapor in any enclosed area, can cause an explosion if ignited. Operate only in wellventilated areas.

57

Liquid Propellant Gas System SAFETY PRECAUTIONS

Before operating the engine, read the

Operator’s Manual and become familiar with it and the equipment. Safe and efficient operation can be achieved only if the equipment is properly operated and maintained.

The following symbols, found throughout this manual, alert you to potentially dangerous conditions to the operator, service personnel, or the equipment.

DANGER

This symbol warns of immediate hazards that will result in severe personal injury or death.

WARNING

This symbol refers to a hazard or unsafe practice that can result in severe personal injury or death.

CAUTION

This symbol refers to a hazard or unsafe practice that can result in personal injury or product or property damage.

Fuels, electrical equipment, batteries, exhaust gases and moving parts present potential hazards that can result in severe personal injury. Take care in following these recommended procedures. All local, state and federal codes should be consulted and complied with.

GENERAL

- Provide appropriate fire extinguishers and install in convenient locations. Use an extinguisher rated

ABC by NFPA.

- Make sure that all fasteners on the engine are secure and accurately torqued. Keep guards in position over fans, driving belts, etc.

- If it is necessary to make adjustments while the engine is running, use extreme caution when close to hot exhausts, moving parts, etc.

- Used engine oils have been identified by some state or federal agencies as causing cancer or reproductive toxicity. When checking or changing engine oil, take care not to ingest, breathe the fumes, or contact used oil.

- Do not work on this equipment when mentally or physically fatigued, or after consuming any alcohol or drug that makes the operation of equipment unsafe.

BATTERIES

- Before starting work on the engine, disconnect batteries to prevent inadvertent starting of the engine.

- DO NOT SMOKE while servicing batteries. Lead acid batteries give off a highly explosive hydrogen gas which can be ignited by flame, electrical arcing or by smoking.

- Verify battery polarity before connecting battery cables. Connect negative cable last.

FUEL SYSTEM

- DO NOT fill fuel tanks while engine is running.

- DO NOT smoke or use an open flame in the vicinity of the engine or fuel tank. Internal combustion engine fuels are highly flammable.

- Fuel line must be LP approved, adequately secured, and free from leaks. Piping at the engine should be approved flexible line. Do not use copper piping for flexible lines as copper will work harder and become brittle enough to break.

- Be sure all fuel supplies have a positive shut-off valve.

PROTECT AGAINST MOVING

PARTS

- Do not wear loose clothing in the vicinity of moving parts, such as

PTO shafts, flywheels, blowers, couplings, fans belts, etc.

- Keep your hands away from moving parts.

EXHAUST SYSTEM

- Exhaust products of any internal combustion engine are toxic and can cause injury, or death if inhaled. When operating the engine in a confined area, make sure the ventilation system is operating properly.

- DO NOT use exhaust gases to heat a compartment.

- Make sure that your exhaust system is free of leaks. Make sure that exhaust manifolds are secure and are not warped by bolts unevenly torqued.

EXHAUST GAS IS DEADLY!

- Exhaust gases contain carbon monoxide, a poisonous gas that can cause unconsciousness and death. It is an odorless and colorless gas formed during combustion of hydrocarbon fuels. Symptoms of carbon monoxide poisoning are:

Dizziness, Headache, Weakness and Sleepiness, Throbbing in Temples, Vomiting, Muscular Twitching

If you experience any of these symptoms, get out into fresh air immediately, shut down the unit and do not use it until it has been inspected.

The best protection against carbon monoxide inhalation is proper installation and regular, frequent inspections of the complete exhaust system. If you notice a change in the sound or appearance of exhaust system, shut the unit down immediately and have it inspected and repaired at once by a competent mechanic.

KEEP THE UNIT AND SURROUND-

ING AREA CLEAN

- Make sure that oily rags are not left on or near the engine.

- Remove all unnecessary grease and oil from the unit. Accumulated grease and oil can cause overheating and subsequent engine damage and present a potential fire hazard.

58

Liquid Propellant Gas System SAFETY INFORMATION

For Your Safety!

These safety precautions should be followed at all times. Failure to follow these safety precautions could result in injury to yourself and others.

Accidental Starts!

Before servicing the engine or equipment, always disconnect the spark plug lead to prevent the engine from starting accidently.

Ground the lead to prevent sparks that could cause fires.

On engines equipped with a 12-volt battery and/or electric start, disconnect the battery cables from the battery. Always disconnect the negative

(-) cable first.

Before disconnecting the negative (-) ground cable, make sure all switches are OFF. If ON, a spark will occur at the ground cable terminal which could cause an explosion if hydrogen gas or fuel vapors are present.

Explosive Fuel

LPG is extremely flammable and is heavier than air and tends to settle in low areas where a spark or flame could ignite the gas. Do not start or operate this engine in a poorly ventilated area where leaking gas could accumulate and endanger the safety of persons in the area.

To insure personal safety, installation and repair of LPG fuel supply systems must be performed only by qualified LPG system technicians.

Improperly installed and maintained

LPG equipment could cause fuel supply system or other components to malfunction, causing gas leaks.

Observe federal, state and local laws governing LPG fuel and systems.

Dangerous Acid, Explosive Gases!

Batteries contain sulfuric acid. To prevent acid burns, avoid contact with skin, eyes and clothing. Batteries produce explosive hydrogen gas while being charged. To prevent a fire or explosion, charge batteries only in well ventilated areas. Keep sparks, open flames, and other sources of ignition away from the battery at all times. Keep batteries out of the reach of children. Remove all jewelry when servicing batteries.

Before disconnecting the negative (-) ground cable, make sure all switches are OFF. If ON, a spark will occur at the ground cable terminal which could cause an explosion if hydrogen gas or gasoline vapors are present.
