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's 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 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.
1.6.4
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
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.
