Perform Maintenance Safely
WARNING! Avoid death or serious injury from
entanglement. Do not wear loose clothing or
accessories. Stay away from all rotating components
when the engine is running.
Contact, wrapping or
entanglement with rotating or moving parts could result in
death or serious injury.
Wear a rubber apron and rubber gloves when working
with corrosives. Wear gloves and safety shoes when
handling wooden blocks or sharp-edged metal.
Always use safety glasses, goggles or a face shield.
They provide eye protection from fluids under pressure,
during grinding and while servicing batteries. Protection
is also needed from flying debris, liquids and loose
material produced by equipment, tools and pressurized
air/water.
Wear a face shield and follow manufacturer’s instructions
when you disassemble spring-loaded components or work
with battery acids. Keep pockets free of all objects that
could fall out and drop into machinery.
Handle tools and heavy parts sensibly, with regard for
the safety of yourself and others. Lower items; don’t
drop them.

Perform Maintenance Safely
Prepare the Work Area
• Position the machine in a level area out of the way of
other working equipment
• Make sure there is adequate light, ventilation and
clearance
• Remove oil, grease or water to eliminate any slippery
surfaces
• Clean around the area to be serviced to minimize
contamination
Prepare the Machine
Stored energy sources (electrical, mechanical, hydraulic,
pneumatic, chemical, thermal, etc.) must be controlled
or reduced to a practical minimum before performing
any maintenance, repair, or service procedures.
Safety practices to prevent potential injuries from
energy-releasing sources include:
• Place controls in NEUTRAL or LOCKED position
before shutting off engine
• Allow all moving parts to stop
• Shut off engine
• Relieve hydraulic system pressure by moving controls
several times in all directions
• Lock ignition, remove key (if equipped) and take it
with you
• Look and listen for evidence of moving parts before
servicing
• Shut off master electrical switch (if equipped)
• Securely support or block up machine before working
underneath machine or other lifted components
• Securely support, block up, or lock up other
components with approved locking devices before
working near or underneath them
• Relieve pressure before disconnecting or
disassembling any pressurized system
• Block or relieve spring pressure before disassembling
any spring-loaded mechanism
• Avoid flames, sparks, or smoking near any fuel,
hydraulic fluid or other flammable material such as
spraying debris
Avoid falls, clean
slippery surfaces
