OPERATING THE ENGINE
16
ENGLISH
COLD WEATHER STARTING
If the ambient temperature is below 0
(32
) and the
engine is very cold, start it in the following manner:
1. Place the choke lever to the "ON" position, and place
the throttle lever midway between the "SLOW" and the
"FAST" positions.
2. Turn the key switch to the START (" ") position.
A
Operate the starter 10 seconds.
A
If the engine does not start, wait 60 seconds.
A
Repeat this procedure until the engine starts.
3. When the engine starts, release the key to the "ON"
(" ") position.
WARMING UP
To avoid serious injury:
A
Be sure to apply the parking brake during
warm-up.
For 5 minutes after engine start-up, allow the engine to
warm up without applying any load. This is to allow oil to
reach every part of the engine. If load should be applied
to the engine without this warm-up period, problems may
develop such as seizure, breakage or premature wear.
B
Warm-up and Transmission Oil in the Low
Temperature Range
Hydraulic oil serves as transmission oil. In cold weather,
the oil may be cold with increased viscosity. This can
cause delayed oil circulation or abnormally low hydraulic
pressure for some time after engine start-up. This in turn
can create problems with the hydraulic system.
To prevent the above, observe the following instructions:
Warm up the engine at about 50% of rated rpm according
to the table below:
A
Do not operate unless the engine is well warmed up. If
operation is attempted while the engine is still cold, the
hydraulic mechanism will not function properly and its
service life will be shortened.
JUMP STARTING
To avoid serious injury:
A
Keep cigarettes, sparks, and flames away from
battery.
A
If the machine battery is frozen, do not jump
start the engine.
A
Do not connect the other end of negative
jumper cable to the negative terminal of the
machine battery.
When jump starting the engine, follow the instructions
below to start the engine safely.
1. Bring a helper vehicle with a battery of the same
voltage as the disabled machine within easy cable
reach. "THE VEHICLES MUST NOT TOUCH".
2. Apply the parking brakes of both vehicles and put the
shift levers in neutral. Shut the engine off.
3. Put on safety goggles and rubber gloves.
4. Ensure vent caps are securely in place (if equipped).
5. Attach the red clamp to the positive (red, (+) or pos.)
terminal of the dead battery and clamp the other end
of the same cable to the positive (red, (+) or pos.)
terminal of the helper battery.
6. Clamp the other cable to the negative (black, (-) or
neg.) terminal of the helper battery.
7. Clamp the other end to the engine block or the frame
of the disabled machine as far from the dead battery
as possible.
8. Start the helper vehicle and let its engine run for a few
moments. Start the disabled machine.
9. Disconnect the jumper cables in the exact reverse
order of attachment. (Steps 7, 6 and 5)
A
This machine has a 12 volt negative (-) ground starting
system.
A
Use only same voltage for jump starting.
