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 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 allow pressure to escape before removing the cap
completely. Failure to follow the safety practices could
result in death or serious injury.
FLUID FLAMABILTITY: DO NOT service the fuel or
hydraulic systems near an open flame, sparks or smoking
materials.
Properly disconnect battery prior to servicing the fuel or
hydraulic systems.
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.
