Safety Training
1. Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to provide safe
equipment can be wiped out by a single careless act of an operator or bystander.
2. In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the
awareness, concern, prudence, and proper training of personnel involved in the operation, transport, maintenance, and
storage of this equipment.
3. It has been said, "The best safety feature is an informed, careful operator." We ask you to be that kind of an operator. It is
the operator's responsibility to read and understand ALL Safety and Using instructions in the manual and to follow these.
Accidents can be avoided.
4. If this machine is used by any person other than yourself, or is loaned or rented, it is the machine owner's responsibility to

Safety Decals
Preparation
1. Never use the machine until you have
read and completely understand this manual, the skid steer tractor Operator's Manual and each of the
Safety Messages found on the safety signs on the skid steer tractor and machine.
2. Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are
recommended during assembly, installation, operation, adjustment, maintaining, repairing, removal, cleaning, or moving
the unit. Do not allow long hair, loose fitting clothing or jewelry to be around equipment.
3. PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT HEARING LOSS!
Power equipment with or without equipment attached can often be noisy enough to cause permanent, partial hearing loss. We
recommend that you wear hearing protection on a full-time basis if the noise in the Operator's position exceeds 80db. Noise
over 85db on a long-term basis can cause severe hearing loss. Noise over 90db adjacent to the Operator over a long-term basis
may cause permanent, total hearing loss. NOTE: Hearing loss from loud noise (from tractors, chain saws, radios, and other
such sources close to the ear) is cumulative over a lifetime without hope of natural recovery.
4. Clear working area of stones, branches or hidden obstacles that might be hooked or snagged, causing injury or damage.
5. Use only in daylight or good artificial light.
6. Be sure machine is properly mounted, adjusted and in good operating condition.
7. Ensure that all safety shielding, and safety signs are properly installed and in good condition.
Maintenance Safety
1. Good maintenance is your responsibility. Poor maintenance is an invitation to trouble.

www.tmgindustrial.com 7 / 16 TOLL FREE: 1-877-761-2819
2. Follow good shop practices.
a) Keep service area clean and dry.
b) Be sure electrical outlets and tools are properly grounded.
c) Use adequate light for the job at hand.
3. Make sure there is plenty of ventilation. Never operate the engine of the towing vehicle in a closed building. The exhaust
fumes may cause asphyxiation.
4. Before working on this machine, shut off the engine, set the brake, and turn fuel valve off.
5. Never work under equipment unless itis blocked securely.
6. Always use personal protection devices such as eye, hand and hearing protectors, when performing any service or
maintenance work. Use heavy or leather gloves when handling blades.
7. Where replacement parts are necessary for periodic maintenance and servicing, genuine factory replacement parts must
be used to restore your equipment to original specifications. The manufacturer will not be responsible for injuries or
damages caused by use of unapproved parts and/or accessories.
8. A fire extinguisher and first aid kit should be kept readily accessible while performing maintenance on this equipment.
9. Periodically tighten all bolts, nuts and screws and check that all electrical and fuel connections are properly secured to
ensure unit is in a safe condition.
10. When completing a maintenance or service function, make sure all safety shields and devices are installed before placing
unit in service.
Hydraulic Safety
1. Make sure that all the components in the hydraulic system are kept in good condition and are clean.
2. Before applying pressure to the system, make sure all components are tight, and that lines, hoses and couplings are not
damaged.
3. Do not attempt any makeshift repairs to the hydraulic lines, fittings, or hoses by using tapes, clamps or cements. The
hydraulic system operates under extremely high pressure. Such repairs will fail suddenly and create a hazardous and
unsafe condition.

www.tmgindustrial.com 8 / 16 TOLL FREE: 1-877-761-2819
4. Wear proper hand and eye protection when searching for a high-pressure hydraulic leak. Use a piece of wood or cardboard
as a backstop instead of hands to isolate and identify a leak.
5. If injured by a concentrated high-pressure stream of hydraulic fluid, seek medical attention immediately. Serious infection
or toxic reaction can develop from hydraulic fluid piercing the skin surface.
6. Relieve pressure on hydraulic system before maintaining or working on system.
Transport Safety
1. Comply with state and local laws governing safety and transporting of machinery on public roads.
2. Check that all the lights, reflectors and other lighting requirements are installed and in good working condition.
3. Do not exceed a safe travel speed. Slow down for rough terrain and cornering.
4. Do not drink and drive.
5. Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including narrow bridges, intersections,
etc. Watch for traffic when operating near or crossing roadways.
To the New Operator or Owner
Follow all safety instructions exactly. Safety is everyone's business. By following recommended procedures, a safe working
environment is provided for the operator, bystanders, and the area around the worksite. Untrained operators are not qualified to
operate the machine.
Many features incorporated into this machine are the result of suggestions made by customers like you. Read this manual
carefully to learn how to use the chipper safely and how to set it to provide maximum field efficiency. By following the using
instructions in conjunction with a good maintenance program, your Skid Steer Flail Mower will provide many years of trouble-
free service.
