Switch, Fuses; Safety System - Husqvarna PT26D Workshop Manual

Switch, fuses

Replacing the switch chronometer and starter switch
The steering arm is secured with four M3-
screws in the ring for rubber bellows. When
assembling the yellow marked screw under
bellows should face forwards.
The tangent switches are secured by four
plastic catches on the underside of the panel.
They must be pushed in when dismantling.
The Chronometer is pop riveted and must be
drilled out when replacing.
The starter switch is secured by a ring nut on
top of the panel.
The power outlet is secured by a ring nut on
the underside of the panel.
Main fuses
If FU3 or FU13 blows, the entire machine will
be dead. If FU12 blows only the indicator
panel works.
The main fuse FU13 is located in a box on
the battery's + pole. Open the cover on box
and check the fuse with a voltmeter during
trouble shooting.
Fuses FU3 for Control circuit
(10 A Red) and FU12 for the feed to the cir-
cuit board (50 A) are located behind the bat-
tery. FU3 is a flat pin loop fuse and you can
see if the loop has burnt off. FU12 is tested in
the same way as FU13 with a voltmeter.

Safety System

PT26D is equipped with a safety system that
prevents starting or driving under the follow-
ing conditions.
The engine can only be started when the
parking brake is applied and the drive pedals
are unactuated. The driver does not need to
be seated in the driver's seat. If the cutting
unit is connected, it is disengaged and must
be re-engaged.
The engine and cutting unit must stop if the
driver leaves the driver's seat when the park-
ing brake is not applied or if any driving pedal
is affected. There is a small delay to prevent
stoppages should the driver bounce in the
seat.
If the safety system is deployed, the switch
for operating the cutting unit must be pressed
in and pulled out again for the cutting unit to
work.
