FILLING COOLANT
CAUTION: PERSONAL INJURY
Only fill coolant when the engine is not running and is at a
low temperature in order to avoid the risk of burns.
1. Ensure the radiator plug located at the bottom of the
radiator and the plug on the engine block are secure.
2. Remove the cap (1) and slowly pour the coolant into
the radiator until it is even with the lip of the filler port.
Ensure no air bubbles develop.
3. Reinstall radiator cap.
CHANGING COOLANT
Engine coolant contaminated
with rust or water scale reduces
the cooling effect. Even when
extended life engine coolant is
properly mixed, the engine
coolant gets contaminated as its
ingredients deteriorate. Drain,
flush and refill the cooling system
with new coolant every 1000
hours or once a year, whichever
comes first.
CAUTION: PERSONAL INJURY
Only proceed when the engine is not running and is at a
low temperature in order to avoid the risk of burns.
1. Remove the cap (1) on the radiator.
2. Remove the drain plug (2) at the bottom of the radiator
and drain the coolant into an approved container.
Reinstall
plug.
3. Remove the coolant drain plug from the engine block.
(see (1) in the following figure)
4. After draining the engine coolant, flush the radiator
and engine block to remove any rust, scale and
contaminants. Then reinstall and tighten the drain plug
or close the drain valve in the radiator. Reinstall and
tighten the engine block drain plug.
5. Fill radiator and engine with engine coolant.
CLEANING RADIATOR
The surfaces of the radiator come into contact with the
outside air and can be subject to deposits and impurities.
Clean in accordance to the maintenance schedule with
compressed air or steam.
CAUTION: PERSONAL INJURY
Always wear eye protection when servicing the engine
and when using compressed air or high-pressure water.
Dust, flying debris, compressed air, pressurized water or
steam may injure your eyes.
1. Blow off dirt and dust from fins and radiator with
28PSI or less compressed air. Be careful not to damage
the fins with the compressed air (1).
2. If there are larger amount of contamination on fins,
apply detergent, thoroughly clean and then rinse with
tap
water.
CHANGING AIR FILTER
The engine performance is adversely affected when
the air cleaner element is clogged with dust.
WARNING: EQUIPMENT DAMAGE
Never operate the engine with the air cleaner element
removed. This may allow foreign material to enter the
engine and damage it. Do NOT remove filter while engine
is running.
1. Unlatch and remove the air cleaner cover (1).
2. Remove the element (2).
3. Blow air (Figure 13, (3)) through the element from the
inside out using 42 - 71 PSI compressed air to remove
the particulates. Use the lowest possible air pressure to
remove the dust without damaging the element.
