Handling Vehicle In Hot Season; Long Term Storage - Toyota 30-5SDK5 Operator's Manual

HANDLING VEHICLE IN HOT SEASON

During hot weather, the following areas are of
concern:
Cooling unit
1. As water scale and rust easily take place in
cooling system (especially in radiator) in
hot season, remove water scale and rust
with water or cleaning agent and always
try to circulate clean water in the cooling
system.
2. Clean radiator fins with compressed air to
avoid clogging, resulting in overheating.
Inspect the radiator for water leaks.
3. Inspect the fan belt for slack. If it is slack,
adjust it to the prescribed tension.
4. When the engine is overheated and cool-
ant boils, do not stop the engine immedi-
ately, but let it rotate at an idle speed for a
while. After the water temperature drops,
stop the engine. Also, open the engine
hood to expedite cooling.
Heat protection function
If the hydraulic oil temperature reaches 85°C
while performing material handling and attach-
ment operations or while traveling, this function
will activate a warning buzzer to warn the oper-
ator.
When the warning buzzer sounds, immediately
stop operation and run the engine at a speed
slightly faster than idling speed, and allow the
hydraulic oil to cool.
Overheat automatic stop circuit
(Only on vehicles with Australian specifica-
tions)
If the hydraulic oil temperature reaches 100°C
while performing material handling and attach-
ment operations or while traveling, the material
handling operation will stop.
When the material handling operation stops,
immediately run the engine at a speed slightly
faster than idling speed, and allow the hydraulic
oil to cool.

Caution Caution
• Do not remove the radiator cap to expe-
dite cooling because it is very dangerous.
• If the HST oil temperature warning lamp
lights and the warning buzzer sounds,
stop the vehicle immediately, and allow
the hydraulic oil to cool. If the engine
overheats, the HST may be damaged.

LONG TERM STORAGE

Before storage without operation
If the vehicle is to be stored for a long period of
time, pay close attention to the following:
1. Carefully wash and clean each part.
2. Perform lubrication and oil change for all
necessary parts without omission.
3. Apply grease thinly on the exposed por-
tions of hydraulic cylinder piston rods.
4. If a long life coolant is not used, thor-
oughly drain the coolant from the cylinder
block and radiator.
5. Remove the battery after full charging,
and store it in a cool, dry place.
6. Pull the accelerator lever fully backward
and keep the ignition switch at the OFF
position.
7. Store the vehicle indoors. If outdoor stor-
age is unavoidable, place the vehicle on
blocks and cover with waterproof canvas.
During storage
During storage, run the engine, move the vehi-
cle back and forth, and operate each pedal at
least once a month for lubrication of each part.
Caution Caution
When operating hydraulic cylinders, wipe
off grease applied to piston rods. Charge the
battery sufficiently whenever the engine is
started. (Supplementary charging is neces-
sary every month to prevent degradation due
to self discharge.)
After long storage
Pay attention to the following points when oper-
ating the vehicle that has been stored for a long
period without operation.
1. Remove the drain plug from the fuel tank,
oil pan, etc., to drain water accumulated in
each part.
2. After starting the engine, carry out suffi-
cient warm up and inspect each part care-
fully.
