7. Operation
7.1 Work Site Safety
WARNING!
Electrocution Hazard. Be aware of overhead
or underground power lines. Stay at least 20 ft
(6 m) or more away. Serious injury or death
could occur from electrocution. Electrocution is
possible without direct contact (arcing).

• For safety of others during operation, set up a Work Zone
around the machine. Mark the area with safety cones. For
more information, see
Set Up a Work Zone on page 11.
• Plan your excavation ahead of time. Determine where
excavated soil will be dumped. Position the machine
to minimize the distance of travel between digging and
dumping. The shorter the travel distance, the faster the dig
/ dump cycle and more work that can be done.
• Be aware of buried or overhead wires, cables, pipes, or
other obstructions. Contact your local utility company to
mark their location.
• If working in a close or cramped space, be sure there is
sufficient room for the machine to dig, swing, and dump.
Modify the work site to provide more area. Unplanned
contact with adjacent buildings, equipment or terrain can
cause loss of control leading to injury or damage.
• Be aware of prevailing winds. Set-up the work site so
prevailing winds blow exhaust, dust, and debris away from
the operator. As a result, the work zone becomes safer as
vision is not be obscured while digging and dumping.
• Do not operate inside a building. Gas and diesel engines
produce carbon monoxide that can cause asphyxiation.
• Be aware of bystanders. Do not permit bystanders, on-
lookers, or unauthorized personnel in the work area. Stop
the machine if anyone enters the working area. There is
always the risk of someone getting in the way or getting
pinched / caught by components. Do not resume work until
the work zone is clear.
• Do not try to lift objects that are beyond the lifting limits of
the machine. Be aware of people and objects when lifting.
When moving a load, travel slowly and know the travel
path.
• The recommended travel for a skid steer is up or down a
slope, not across it. Keep the skid digger low to the ground
to improve stability. Extra care is required if working on a
slope. If working on a slope is necessary, work the boom
up-slope to minimize the chance of tipping.
7.2 Before Startup
Each operator must be trained in the proper operating
procedures prior to operating the machine.
• Review location of the controls, their function, and
movement direction when activated.
• Follow the Pre-Operation Checklist.
7.2.1 Pre-operation Checklist
Before operating the machine, check the following:
Pre-operation Checklist
Check that the
skid digger
is securely and correctly
attached to the skid steer. For instructions, see Attach to a
Skid Steer on page 19.
Check and lubricate the
skid digger
as described in the
Maintenance Schedule on page 27 .
Check for and remove entangled material.
Check that the bucket linkage moves freely.
Check the condition of the bucket teeth. If required, replace
damaged teeth. For instructions, see
Replace a Bucket
Tooth on page 28.
Check that hydraulic hoses are not chafed, pinched, or
crimped. Reroute, as required.
Check for hydraulic leaks. For important safety
instructions, see
Hydraulic System Safety on page 26 .
Tighten fittings or replace components to stop leaks. For
torque specifications, see
Hydraulic Fitting Torque Values
on page 32.
Check all fasteners and hardware. Tighten to the specified
torque, as required. For torque specifications, see
Common Bolt Torque Values on page 31 .
