Presentation
Do not smoke when filling the tank with fuel.
Diesel is less flammab
le than petrol at normal temperatures, but becomes very flammable if heated to the flash
point. This varies depending on the type of diesel but is normally higher than +50 °C (120 °F).
Observe fuel hygiene. The diesel engine’s fuel injection system is very sensitive and can be damaged by
contaminants, which may be so small that they cannot be seen with the naked eye. Only use clean containers
(closed + dust-free funnel). Wipe away any dust before removing the fuel tank filler cap. There is a filter to protect the
fuel injection system, however if it becomes blocked operational malfunctions may occur. Rectifying damage,
operational malfunctions, filter replacement caused by poor hygiene are not repairs that are covered under warranty
Remember the environmental risks. See “Environment protection” on page 26.
Wipe up any spillages. Material that has been contaminated by fuel must be moved to a safe place.
If you spill fuel on your clothes, change to prevent skin irritations.
Winter fuel and paraffin precipitation
Malfunctioning can occur when driving in extremely
cold conditions on account of paraffin precipitation,
which can occur if using standard fuel. To avoid this,
winter fuel, diesel with additives to prevent precipitation,
is sold in relevant climates. In certain regions different
types of summer and winter fuels are sold, in other
regions. winter fuel is sold all year round. Ask you fuel
supplier and only use winter fuel below 0 °C (+32 °F).
21-37. Controls on the control panel
The control panel is prepared for optional extras, which
are sold as accessories for PT 26D. Therefore, some
of the following control units may not be included with
your machine.
21. Control lever hydraulics
The lifting lever is used to put the cutting unit in either
the transport or mowing position when hydraulic
pressure is available.
Lifting the cutting unit (transport position)
Stop the blades by pressing in the switch for driving the
cutting unit (22).
Pull the lever backward to engage the transport position.
The unit is then raised.
The cutting unit can be raised slightly with the blades
in operation. This is to facilitate work when cutting in
extremely tall grass or on uneven surfaces. The
machine is, however, equipped with an automatic
blade stop function, which is activated when the cutting
unit reaches the transport position. If the automatic
blade stop is activated, the switch (22) must be
pressed in and pulled out to restart.
Lowering the unit (mowing position)
Move the lifting lever forwards to engage the cutting
position. The unit is then lowered. The lever does not
need to be held in position, allow it to spring back to
the zero position when the unit has been lowered.
The blades are started with the switch for driving the
cutting unit (22).
Weight transfer can be activated, which means the cutting
unit follows the ground contour and unevenness on the
lawn more precisely. See “Weight transfer” page 23
