Handling Vehicle In Cold Season - Toyota 30-5SDK5 Operator's Manual

HANDLING VEHICLE IN COLD SEASON

Pay attention to the following points in cold
weather because starting difficulty or coolant
freezing will occur.
1. Caution when fueling
Always replenish fuel until the tank is full.
In cold weather, it is advisable to keep fuel
tank levels high.
Caution Caution
Firmly tighten the tank cap to prevent rain
or snow from entering.
2. Caution for cooling system
(1) Long-life coolant (L.L.C.) 50% solution
or antifreeze solution must be added to the
cooling system (before outdoor tempera-
ture becomes lower than 0°C (32°F).)
3. Caution for batteries
(1) In very cold weather, the battery perfor-
mance is lowered and battery fluid may
freeze if charging is insufficient.
Try to keep the battery always in the fully
charged state.
(2) If the vehicle is not to be used for a long
period of time in very cold weather,
remove the battery and store in a warm
place.
(3) Immediately before using the vehicle (or
immediately before charging), replenish
refined water in an exceedingly cold
place.
(4) When it is difficult to start the engine,
always do not apply hot water to the bat-
tery case to improve the battery perfor-
mance. Pay special attention, because the
case may be broken because of a change in
temperature.
Starting in cold season
Low temperature causes battery performance to
lower and viscosity of lubricating oil to
increase, both of which make the engine starting
more difficult.
In cold season, the engine is started in the fol-
lowing way:
1. Set the accelerator lever to maximum
speed position.
2. With the ignition switch in the ON (30-
5SDK9 • 10 • 11) or GLOW (30-5SDK5 •
8) position, make sure that the glow indi-
cator lamp (30-5SDK5 • 8) or the preheat-
ing indicator lamp (30-5SDK9 • 10 • 11)
goes on once and in a moment i.e. 2-7 sec-
onds case of 30-5SDK9 • 10 • 11, and
approx. 15 seconds case of 30-5SDK5 • 8,
it goes off again.
3. With the ignition switch ON, make sure
that each warning lamp goes on.
4. Set the ignition switch into "START"
position and activate the starter motor
(continuous less than 30 seconds) to start
the engine.
5. As soon as the engine starts, take hands
off the key. It automatically returns to the
ON position.
6. As soon as the engine speed has stabilized,
put the accelerator lever in the IDLE posi-
tion and let the engine warm up for 10 or
15 minutes.
When it is difficult to start the
engine
1. Do not use the starter motor continuously
more than 30 seconds.
When it is difficult to start the engine, stop
the starter motor operation momentarily
and wait until the battery restores to
restart.
2. When it is difficult to start the engine, do
not repeat the starting procedure many
times but inspect whether there is fuel in
the fuel tank, whether air is mixed in the
fuel system and whether the glow plug is
not disconnected and the thermostat plug
is not disconnected.
3. The engine may not reach the starting rpm
and start even if the starter motor is acti-
vated. In such a case, use an auxiliary bat-
tery to start the engine.
Pay special attention not to connect mis-
takenly plus and minus terminals.
After using vehicle
1. Clean off any mud or dirt that may be
adhering to the vehicle and park the vehi-
cle on a hard, dry surface such as concrete.
If this is not done, the mud may freeze
during the night and prevent the vehicle
from being operated the next morning.
This especially applies to the surface of
the hydraulic cylinder piston rods: always
dry these off, because the rod packing can
be damaged if water gets into it and
freeze.
2. Loosen the fuel tank drain plug and loosen
sedimenter drain plug and drain the water
out of the fuel system to prevent it from
freezing during the night.
Caution Caution
When the cold season passes and the weather
begins to warm up, bring the oil and fuel
back up to standard specifications.
