Starting The Engine With A Weak Battery - Husqvarna P520 D Operator's Manual

7 When the engine starts release the ignition key
immediately back to neutral position.
8 Set the required engine speed with the throttle control.
Let the engine run at moderate speed or half throttle for 3-
5 minutes before subjecting it to heavy load.
IMPORTANT!
Do not run the starter for more than about 15 seconds at a
time. If the engine does not start, wait about 15 seconds
before trying again.
WARNING! Never run the engine indoors, in
!
enclosed or poorly ventilated areas. The
exhaust fumes contain toxic carbon
monoxide.
Starting when cold
If the engine fails to start due to the cold, repeat ignition and
attempt to re-start. Start gas or ether must not be used.
For more information about winter fuel, please see 'Fuel
handling'.
IMPORTANT! At temperatures below 0 ° C, the machine
must be warmed up for at least 10 minutes for the hydraulic
oil and transmission to get hot. Otherwise there is a risk of
the transmission breaking down thereby reducing the
service life of the transmission.
Starting the engine with a weak
battery
WARNING! Lead-acid batteries produce
!
explosive gases. Avoid sparks, open flames
and smoking close to batteries. Always wear
protective glasses in the vicinity of batteries.
If the battery is too weak to start the engine, it should be
recharged.
When jump leads are used for emergency starting, follow the
procedure below:
IMPORTANT! Your Rider is equipped with a 12-volt system
with negative earth. The other vehicle must also have a 12-
volt system with negative earth. Do not use your Rider
battery to start other vehicles.
STARTING AND STOPPING
Connecting the jump leads
WARNING! Never connect the negative
!
terminal of the fully-charged battery to, or in
the vicinity of, the negative terminal of the
discharged battery. Hydrogen gas may be
present with risk of explosion.
• Connect each end of the red cable to the POSITIVE pole
(+) on each battery, exercise care not to short circuit any
of the ends against the chassis.
• Connect one end of the black cable to the NEGATIVE pole
(-) on the fully charged battery.
• Connect the other end of the black cable to a good
CHASSIS EARTH, away from the fuel tank and the
battery.
Remove the cables in the reverse order
• The BLACK cable is removed from the chassis and then
the fully charged battery.
• Finally the RED cable from both batteries.
IMPORTANT!
Never use a boost charger/start booster.
Use only conventional battery chargers. Always disconnect
the charger before starting the engine. So called boost
chargers/start boosters must never be used. These will
often increase the voltage (instead of the current) to
generate the power needed to start the engine. This
increase in voltage will damage the electrical system.
