Wheel Loader Safety
Hydraulic System
Check hydraulic tubes, hoses and fittings for damage, wear or
for leaks. Hydraulic lines and hoses must be properly routed and
have adequate support and secure clamps. Leaks can cause
fires. Never use a flame or bare skin to check for leaks.
Tighten or replace any parts that show leakage.
Check that all hose and tube clamps, guards, and cushions are
securely attached. If they are loose, they can vibrate during
operation and rub against other parts. This can cause damage
to hoses and cause high-pressure oil to spray on hot surfaces,
causing a fire and death or serious injury.
Always clean fluid spills. Do not use gasoline or diesel fuel for
cleaning parts. Use commercial nonflammable solvents.
Fueling
Use caution when you are refueling a machine.
Fuel is flammable and can catch fire if it is brought close to a
flame.
Stop engine and let it cool before adding fuel. Do not smoke
while you are refueling a machine. Do not refuel a machine near
flames or sparks. Fill fuel tank outdoors.
Keep fuel and other fluid reservoir caps tight and do not start
engine until caps have been secured.
Store fuels and lubricants in properly marked containers away
from unauthorized personnel. Store oily rags and any flammable
materials in protective containers.
Static electricity can produce dangerous sparks at fuel filling
nozzle. In very cold, dry weather or other conditions that could
produce a static discharge, keep tip of fuel nozzle in constant
contact with neck of fuel filling nozzle, to provide a ground and
prevent sparks.
Always place plastic fuel containers on the ground before filling.
