Safety Practices
1-4 3614RS, 4017RS
1.7.3 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, JLG
recommends a maximum pressure of 52 bar (750 psi) at a
minimum distance of 30,5 cm (12 in) 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.
1.7.4 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.
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
coolant system cap while the cooling system is hot. Wear
safety glasses. Turn the coolant system 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.
