!
!
Safety Training
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. !
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. !
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

!
!
Safety Signs
Always keep safety signs clean and legible. !
Replace safety signs that are missing or have become illegible. !
Replaced parts that displayed a safety sign should also display the current sign. !
Safety signs have a part number in the lower righthand corner. Use this part number when
ordering !replacement parts. !

or moving the unit. Do not allow long hair, loose fitting clothing or jewelry to be around equipment. !
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 skid steer, chain saws, radios, and other such sources close to
the ear) is cumulative over a lifetime without hope of natural recovery. !
Clear working area of stones, branches or hidden obstacles that might be hooked or snagged, causing injury
or damage. !
Use only in daylight or good artificial light. !
Be sure machine is properly mounted, adjusted and in good operating condition. !
Ensure that all safety shielding, and safety signs are properly installed and in good condition. !

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.
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.
