COLD WEATHER OPERATION
STARTING USING MANUAL
PREHEATING
When the engine water tempera-
ture is above 13"C, automatic pre-
heating
cannot be carried out.
(When the preheat switch is turned
to AUTO, the preheating monitor
lamp goes out.) If it is difficult to
start the engine, use the following
procedure.
1) Put starting switch key to ON
position.
2) Keep the preheater switch in
ON position with hand until
the preheating monitor goes
off.
3) As soon as light goes off,
quickly return starting switch
to START position, and start
engine.
4) After starting, put preheater
switch in OFF position.
A
There is a danger of explosion
when using a starting aid liquid
for starting the engine, there-
fore, never use it.
CAUTIONS AFTER
COMPLETION OF WORK
1. Mud and water on the machine
body
should be completely
removed.
Park the machine on concrete or
hard ground. If this is impossible,
park the machine on wooden
boards. This will prevent the ac-
cessories from freezing to the
ground thereby preventing ma-
chine movement the next morn-
ing. Particular attention should be
given to water drops collected on
the surface of the hydraulic cylin-
der piston rods. Such droplets
must be fully wiped off because
if water is frozen to the rod when
the cylinder is utilized, the cylin-
der oil seals may be damaged.
2. Drain water collected in air tank
and fuel system so that such
water may be frozen at night.
3. As battery capacity drops at low
ambient temperature, cover the
battery or remove it from the ma-
chine to be kept warm at night.
