1.6 SAFETY INSTRUCTIONS
Following are general safety statements to consider before
performing maintenance procedures on the telehandler.
Additional statements related to specific tasks and
procedures are located throughout this manual and are
listed prior to any work instructions to provide safety
information before the potential of a hazard occurs.
For all safety messages, carefully read, understand and follow
the instructions before proceeding.
1.6.1 Personal Hazards
PERSONAL SAFETY GEAR: Wear all the protective clothing
and personal safety gear necessary to perform the job safely.
This might include heavy gloves, safety glasses or goggles,
filter mask or respirator, safety shoes or a hard hat.
LIFTING: NEVER lift a heavy object without the help of at
least one assistant or a suitable sling and hoist.
1.6.2 Equipment Hazards
LIFTING OF EQUIPMENT: Before using any lifting equipment
(chains, slings, brackets, hooks, etc.), verify that it is of the
proper capacity, in good working order, and is properly
attached.
NEVER stand or otherwise become positioned under a
suspended load or under raised equipment. The load or
equipment could fall or tip.
DO NOT use a hoist, jack or jack stands only to support
equipment. Always support equipment with the proper
capacity blocks or stands properly rated for the load.
HAND TOOLS: Always use the proper tool for the job; keep
tools clean and in good working order, and use special
service tools only as recommended.
1.6.3 General Hazards
SOLVENTS: Only use approved solvents that are known to be
safe for use.
HOUSEKEEPING: Keep the work area and operator cab clean,
and remove all hazards (debris, oil, tools, etc.).
FIRST AID: Immediately clean, dress and report all injuries
(cuts, abrasions, burns, etc.), no matter how minor the injury
may seem. Know the location of a First Aid Kit, and know how
to use it.
CLEANLINESS: Wear eye protection, and clean all
components with a high-pressure or steam cleaner before
attempting service.
When removing hydraulic components, plug hose ends and
connections to prevent excess leakage and contamination.
Place a suitable catch basin beneath the machine to capture
fluid run-off.
It is good practice to avoid pressure-washing electrical/
electronic components. In the event pressure-washing the
machine is needed, ensure the machine is shut down before
pressure-washing. Should pressure-washing be utilized to
wash areas containing electrical/electronic components, it is
recommended a maximum pressure of 750 psi (52 bar) at a
minimum distance of 12 in (30,5 cm) away from these
components. If electrical/electronic components are
sprayed, spraying must not be direct and for brief time
periods to avoid heavy saturation.
Check and obey all Federal, State and/or Local regulations
regarding waste storage, disposal and recycling.

Safety Practices
1-4 31211015 6036, 6042, 8042, 10042, 10054
1.6.4 Operational Hazards
ENGINE: Stop the engine before performing any service
unless specifically instructed otherwise.
VENTILATION: Avoid prolonged engine operation in
enclosed areas without adequate ventilation.
SOFT SURFACES AND SLOPES: NEVER work on a machine
that is parked on a soft surface or slope. The machine must be
on a hard level surface, with the wheels blocked before
performing any service.
FLUID TEMPERATURE: NEVER work on a machine when the
engine, cooling or hydraulic systems are hot. Hot
components and fluids can cause severe burns. Allow
systems to cool before proceeding.
FLUID PRESSURE: Before loosening any hydraulic or diesel
fuel component, hose or tube, turn the engine OFF. Wear
heavy, protective gloves and eye protection. NEVER check
for leaks using any part of your body; use a piece of
cardboard or wood instead. If injured, seek medical attention
immediately. Diesel fluid leaking under pressure can
explode. Hydraulic fluid and diesel fuel leaking under
pressure can penetrate the skin, cause infection, gangrene
and other serious personal injury.
Engine fuel lines are pressurized. DO NOT attempt repairs
unless specific training has been completed. Refer to the
engine manufacturers’ manual for specific details
concerning the fuel system.
Relieve all pressure before disconnecting any component,
part, line or hose. Slowly loosen parts and allow release of
residual pressure before removing any part or component.
Before starting the engine or applying pressure, use
components, parts, hoses and pipes that are in good
condition, connected properly and are tightened to the
proper torque. Capture fluid in an appropriate container and
dispose of in accordance with prevailing environmental
regulations.
COOLANT SYSTEM CAP: The cooling system is under
pressure, and escaping coolant can cause severe burns and
eye injury. To prevent personal injury, NEVER remove the
radiator cap while the cooling system is hot. Wear safety
glasses. Turn the radiator cap to the first stop and allow
pressure to escape before removing the cap completely.
Failure to follow the safety practices could result in death or
serious injury.
Properly disconnect battery(s) prior to service the fuel or
hydraulic systems.
FLUID FLAMABILTITY: DO NOT service the fuel or hydraulic
systems near an open flame, sparks or smoking materials.
NEVER drain or store fluids in an open container. Engine fuel
and hydraulic fluid are flammable and can cause a fire and/or
explosion.
DO NOT mix gasoline or alcohol with diesel fuel. The mixture
can cause an explosion.
PRESSURE TESTING: When conducting any test, only use test
equipment that is correctly calibrated and in good condition.
Use the correct equipment in the proper manner, and make
changes or repairs as indicated by the test procedure to
achieve the desired result.
LEAVING MACHINE: Lower the forks or attachment to the
ground before leaving the machine.
TIRES: Always keep tires inflated to the proper pressure to
help prevent tipover. DO NOT over-inflate tires.
NEVER use mismatched tire types, sizes or ply ratings.
Always use matched sets according to machine
specifications.
MAJOR COMPONENTS: Never alter, remove, or substitute any
items such as counterweights, tires, batteries or other items
that may reduce or affect the overall weight or stability of the
machine.
BATTERY: DO NOT charge a frozen battery.Charging a frozen
battery may cause it to explode. Allow the battery to thaw
before jump-starting or connecting a battery charger.
1.7 SAFETY DECALS
Check that all safety decals are present and readable on the
machine. Refer to the Operation & Safety Manual supplied
with machine for information.
