Starting And Stopping; Starting For The First Time; Check Before Starting; Starting - Husqvarna PP 518 Manuel D'utilisation

Before starting
WARNING! Please read the operator's
!
manual carefully and make sure you
understand the instructions before using the
machine.
Wear personal protective equipment. See
instructions under the heading "Personal
protective equipment".
Make sure no unauthorised persons are in
the working area, otherwise there is a risk of
serious personal injury.
Check that the machine is assembled
correctly and do not show any signs of
damage.
See the instructions under the Assembly and Settings
heading.
• Perform daily maintenance. See instructions under the
heading Maintenance.
WARNING! The engine emits carbon
!
monoxide, which is a colourless, poisonous
gas. Do not use the machine in enclosed
spaces.
Starting for the first time
If the power unit is delivered without hydraulic oil in the tank
and hoses, the oil levels must be carefully inspected, before
using the unit for the first time.
A new set of empty hydraulic hoses requires approximately
1.8 l (2 qt) of oil.
When the power unit has been started for the first time and
the flow switch has been adjusted to the required setting, the
hydraulic hoses will fill with oil. Before the machine is used,
the level in the hydraulic oil tank must be checked.
If necessary, stop the engine and fill with hydraulic oil.

Check before starting

Before starting the hydraulic unit, check that:
• The battery is charged and fitted correctly.
• The tyres are correctly inflated.
• The engine oil level is correct.
• The fuel tank is filled with fresh and clean, unleaded
regular petrol.
• The hydraulic oil tank is filled to the correct level.
• You are familiar with the location of the controls and their
function. Test them before you start the engine.
• You have connected the hydraulic hoses to the hydraulic
unit and connected the other ends to a hydraulic tool or to
each other.
• Always set the flow switch to position 0 before starting.
IMPORTANT! Check the various parts and
!
components in the hydraulic unit for damage
before each use. Pay special attention to
petrol or oil leaks.

STARTING AND STOPPING

Starting

Always start the engine with flow switch set in the 0 position
and the throttle in position 1.
The throttle lever switch allows you to select one of two
modes of operation for the throttle.
The switch for the automatic throttle can be set to either 1 or 0.
• The automatic throttle switch in position 0.
When operating with the lever in position 0, the engine
runs at full speed, from 2,600 to 2,700 rpm (loaded) and
approx. 2,800 rpm (unloaded).
• The automatic throttle switch in position 1.
After starting, the engine's idling speed is about 1,900
rpm.
When the tool is engaged, a pressure switch on the power
unit increases the engine speed to full speed.
When the tool is disengaged, the engine speed is reduced
to 1,900 rpm.
The sensitivity of the control system for the automatic throttle
can be adjusted to compensate for different conditions, such
as increased counter pressure when the hose extensions are
connected, operation at lower temperatures, differences in oil
viscosity, etc.
See instructions under the Adjustment heading.
1 With a cold engine: Pull the choke control fully out.
2 Turn the ignition key to the start position.
3 When the engine starts, immediately release the ignition
key so that it returns to the operating position. Push in the
choke if you used it to start.
4 Allow the engine to warm up for 1 to 2 minutes. Set the
flow switch to the required setting. This allows the
hydraulic oil to flows from the pump through the hoses to
the tool.
In cold weather, we recommend that the hydraulic unit is
allowed to pump oil through the hoses and the tool, until the
oil has reached a temperature of at least 10 °C (50 °F) before
using the tool. This ensures that the automatic throttle switch
functions correctly.
See instructions under the Adjustment heading.
