CT 24-4A Operation

4.3 Recommended Fuel

The engine requires regular grade unleaded gasoline. Use only fresh, clean gasoline. Gasoline containing water or dirt will damage the fuel system. Consult the engine owner’s manual for complete fuel specifications.

Use of oxygenated fuels

Some conventional gasolines are blended with alcohol. These gasolines are collectively referred to as oxygenated fuels. If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement.

Before using an oxygenated fuel, confirm the fuel's contents. Some states and provinces require this information to be posted on the fuel pump.

The following is the Wacker Neuson approved percentage of oxygenates: ETHANOL - (ethyl or grain alcohol) 10% by volume. You may use gasoline

containing up to 10% ethanol by volume (commonly referred to as E10). Gasoline containing more than 10% ethanol (such as E15, E20, or E85) may not be used because it could damage the engine.

If you notice any undesirable operating symptoms, try another service station, or switch to another brand of gasoline.

Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates mentioned above are not covered under warranty.

4.5 Installing Blades

There are two types of blades available for the trowels. Float pans are large “pizza pan” style blades, which hook on over finish blades. Float blades are used in the earliest stages of work, and are not pitched.

Finish blades are used in the final stages of working, and are pro gressively pitched to burnish the concrete.

Note: Trowel blades must NOT be interchanged, i.e., do NOT put larger diameter blades on a smaller diameter trowel.

1. Secure blades to trowel arms with screws (b). Dip threads of screws in grease prior to installation. This will prevent concrete from cementing the screws in place and will make removal of the blades easier later on.

2. Plug the remaining threaded holes in the blade brace with plastic plugs (c) to prevent them from filling with concrete.

Avoid Crystalline Silica (quartz) Dust

WARNING! Avoid exposure to dust containing

crystalline silica particles. This dust can cause serious injury to the lungs (silicosis).

Avoid silica dust

Because crystalline silica is a basic component of sand and granite, many activities at construction sites produce dust containing crystalline silica. Trenching, sawing and boring of material containing crystalline silica can produce dust containing crystalline silica.

If dust which contains crystalline silica is present there are guidelines which should be followed.

1. Be aware of the health effects of crystalline silica and that smoking adds to the damage.

2. Be aware of and follow OSHA (or other) guidelines for exposure to airborne crystalline silica.

3. Know the work operations where exposure to crystalline silica may occur.

4. Participate in air monitoring or training programs offered by the employer.

5. Be aware of and use optional equipment controls such as water sprays, local exhaust ventilation, and enclosed cabs with positive pressure air conditioning.

6. Where respirators are required, wear a respirator approved for protection against crystalline silicacontaining dust. Do not alter the respirator in any way. Workers who use tight-fitting respirators cannot have beards/mustaches which interfere with the respirator seal to the face.

7. If possible, change into disposable or washable work clothes at the worksite; shower and change into clean clothing before leaving the worksite.

8. Do not eat, drink, use tobacco products, or apply cosmetics in areas where there is dust containing crystalline silica.

9. Store food, drink and personal belongings away from the work area.

10. Wash hands and face before eating, drinking, smoking, or applying cosmetics after leaving the exposure area.

Prepare for Safe Operation

Know the Working Area

Learn as much about your working area as possible.

Check at Ground or Floor Level

Thoroughly check the area for unusual or dangerous conditions, such as tools, or items that may damage the trowel or be propelled by the trowels rotating blades. Note where pipes and forms are located. Locate and mark protrusions (rebar, anchor bolts, oor drains, etc.) in the concrete.

Plan Your Work

Know in advance the conditions likely to be encountered, and plan for any likely emergency.

Getting on and off a Ride-On Trowel

If operating a ride-on trowel, mount and dismount carefully. Use the steps and hand holds provided. Do not use control levers as hand holds and never use guard rings as steps. Watch for surfaces that may be slippery. Never jump off a ride-on trowel.
