WARNING
To prevent serious bodily injury from hot coolant or
steam blow-out, never attempt to remove the radiator
cap while the engine is running. Stop the engine and
wait until it is cool. Even then, use extreme care when
removing the cap.
CAUTION:
Do not pour cold water into a hot
!
radiator. Do not operate engine without a proper
coolant mixture. Install cap and tighten securely.
See the engine manufacturer's Owner's Manual for
additional service information.
1. Check coolant level daily. Recovery bottle should be
filled to the cold mark.

6.9 HYDRAULIC HOSES ________________________________________________________

!
WARNING
To prevent serious injury from hot, high pressure oil,
never use your hands to check for oil leaks, use paper
or cardboard.
Hydraulic fluid escaping under pressure can have
sufficient force to penetrate skin. If fluid is injected into
the skin it must be surgically removed within a few
hours by a doctor familiar with this form of injury or
gangrene may result.
1. Always lower implements to ground, disengage park-
ing brake, stop engine and remove key before
inspecting or disconnecting hydraulic lines or hoses.
2. Check visible hoses and tubes daily. Look for wet
hoses or oil spots. Replace worn or damaged hoses
and tubes before operating the machine.
3. The replacement tube or hoses must be routed in
the same path as the existing hose, do not move
clamps, brackets and ties to a new location.
4. Thoroughly inspect all tubes, hoses and connections
every 250 hours.
IMPORTANT: The hydraulic system can be
permanently damaged
contaminated. Before disconnecting any hydraulic
component, clean the area around the fittings and
the hose ends to keep impurities out of the system.

if the oil becomes
2. Mix clean water with ethylene glycol based anti-
freeze for the coldest ambient temperature. Read
and follow the instructions on the anti-freeze
container and engine manual.
3. Keep radiator and hydraulic oil cooler air passages
clean. Use compressed air (30 psi maximum) to
clean the fins.
4. Check and tighten the fan belt annually.
5. Drain and refill coolant system every two years
Remove the radiator cap, open the engine block
drain and the radiator drain. Empty and clean the
recovery bottle.
6. Replace clamps and hoses on radiator every two
years.
7. If you have to add coolant more than once a month,
or add more than one quart at a time, have the
cooling system checked.
a. Before disconnecting any hydraulic component,
tag or mark the location of each hose then clean
the area around the fittings.
b. As you disconnect the component, be prepared
to assemble plugs or caps to the hose ends and
open ports. This will keep impurities out of the
hydraulic system and also prevent oil spills.
c. Make sure "O" rings are clean and hose fittings
are properly seated before tightening.
d. Keep the hose from twisting. Twisted hoses can
cause couplers to loosen as the hose flexes dur-
ing operation resulting in oil leaks.
e. Kinked or twisted hoses can restrict the oil flow
causing the system to malfunction and the oil to
overheat and also lead to hose failure.
