stable supports. Never get under the
machine or working equipment if they are
not sufficiently supported. This procedure
is especially important when working on
hydraulic cylinders.
Secure the engine hood or cover when opened
Be sure to secure the engine hood or cover
when opening it. Do not open the engine
hood or cover on slopes or in strong wind.
Cautions on tilting up the platform
¡ Raising or lowering the platform while the
engine is running may cause the machine
to move, and cause serious injury or
death. Lower the working equipment to the
ground and stop the engine before raising
or lowering the platform.
¡ When the floor is tilted up, support it firmly
with the stopper to prevent it from falling.
Place heavy objects in a stable position
Securely block the working equipment
To prevent unexpected movement, securely
block the working equipment when repairing
or replacing the cutting edges or bucket teeth.
When removing or installing the hoe
attachment, place it in a stable position so
that it does not tip over.

SAFETY
Maintenance Precautions
Use caution when fueling
¡ Do not smoke or permit open flames while
fueling or near fueling operations.
¡ Never remove the fuel cap or refuel with
the engine running or hot. Never allow fuel
to spill on hot machine components.
¡ Maintain control of the fuel filler nozzle
when filling the tank.
¡ Do not fill the fuel tank to capacity. Allow
room for expansion.
¡ Clean up spilled fuel immediately.
¡ Tighten the fuel tank cap securely. Should
the fuel cap be lost, replace it only with
the original manufacturer’s approved cap.
Use of a non-approved cap without proper
venting may result in pressurization of the
tank.
¡ Never use fuel for cleaning purposes.
¡ Use the correct fuel grade for the operating
season.
Be careful with hot and pressurized components
Stop the engine and allow the machine to
cool down before performing inspection and
maintenance.
¡ The engine, muffler, radiator, hydraulic
lines, sliding parts and many other parts
of the machine are hot directly after the
engine is stopped. Touching these parts
will cause burns.
¡ The engine coolant, oil and hydraulic fluid
are also hot and under high pressure.
Be careful when loosening caps and
plugs. Working on the machine under
these conditions could result in burns or
injuries due to the hot oil spurting out.
Be careful with hot cooling systems
Handling of hoses
Fuel, oil or hydraulic fluid leaks can cause a
fire.
¡ Do not twist, bend or hit the hoses.
¡ Never use twisted, bent or cracked hoses,
tubes and pipes. They may burst.
¡ Retighten loose connections.
Do not remove the radiator cap or drain plugs
when the coolant is hot. Stop the engine, let
the engine and radiator cool and loosen the
radiator cap or drain plugs slowly.
