INSTRUCTION - read the
instruction because it has to
do with your safety. Failure to
comply with the instruction may
result in personal injury or even death.
This manual is intended as a service and
repair manual only. The safety instructions
provided herein are for troubleshooting,
service, and repair of the Sitework Systems

Think Safety First
Avoid unexpected starting of engine...
Always turn off the engine and disconnect
the spark plug wire(s) before cleaning,
adjusting, or repair.
Avoid lacerations and amputations...
Stay clear of all moving parts whenever the
engine is running. Treat all normally moving
parts as if they were moving whenever the
engine is running or has the potential to start.
SAFETY INFORMATION
Avoid burns...
Do not touch the engine, muffler, or
other components which may increase in
temperature during operation, while the
unit is running or shortly after it has been
running.
Avoid fires and explosions...
Avoid spilling fuel and never smoke while
working with any type of fuel or lubricant.
Wipe up any spilled fuel or oil immediately.
Never remove the fuel cap or add fuel when
the engine is running. Always use approved,
labeled containers for storing or transporting
fuel and lubricants.
Avoid asphyxiation...
Never operate an engine in a confined area
without proper ventilation.
Avoid injury from batteries...
Battery acid is poisonous and can cause
burns. Avoid contact with skin, eyes, and
clothing. Battery gases can explode. Keep
cigarettes, sparks, and flames away from the
battery.
Avoid injury due to inferior parts...
Use only original equipment parts to ensure
that important safety criteria are met.
Avoid injury to bystanders...
Always clear the area of bystanders before
starting or testing powered equipment.
Avoid injury due to projectiles...
Always clear the area of sticks, rocks, or
any other debris that could be picked up and
thrown by the powered equipment.

SAFETY INFORMATION
Avoid modifications...
Never alter or modify any part unless it is a
factory approved procedure.
Avoid unsafe operation...
Always test the safety interlock system
after making adjustments or repairs on the
machine. Refer to the Electrical section in
this manual for more information.
Hydraulics Safety
• Inspect all hydraulic line connectors and
fittings. Make sure all hydraulic hoses and
lines are in good condition before applying
pressure to the system.
• Keep body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid. Use cardboard or paper to
find hydraulic leaks. Hydraulic fluid escaping
under pressure can penetrate the skin and
cause injury. Fluid accidentally injected into
the skin must be surgically removed within
a few hours by a doctor or gangrene may
occur.
• Before disconnecting or performing any
work on the hydraulic system, lower the
loader arm/attachment to the ground and
stop the engine so all pressure is relieved.
• Be sure you understand a service
procedure before working on the machine.
