Seat lift release
Seat lift release
If the seat lift cannot provide elevation in a normal
manner due to discharged batteries or a broken
actuator, the seat can instead be lifted forward
manually.
1. Remove the plug located on the left side of the
cover, see fig. 4.
2. Unscrew the actuator until it is loose using a
long allen key (10mm), see Fig. 5.
Fig. 6 shows the actuator’s base with the cover
removed.
NOTE! Block the seat up in front before loosening
the screw. The seat is heavy and can fall forwards.
3. Carefully lower the seat forwards.
NOTE! Make sure that the wiring is not stretched
too tightly.
4. Detach the seat lift cover, see page 8.
5. Remount the actuator.

Covers
Removal
1. Run the seat up to its uppermost position.
To manually raise the seat, see page 7.
2. Remove the seat lift cover by lifting it straight
up. It is mounted with hooked pile fabric belts.
3. Then loosen the chassis cover, which is
mounted using four screws. See fig. 8.
NOTE! Be careful when removing the chassis
cover. A chassis equipped with lights has the
wiring for its rear lights fastened to the electronics.
Separate the wiring for the rear lights at the
contact located on the wiring.
4. Remove the two front covers. Each is
mounted with two screws, see fig. 9.
Fitting
Mounting is performed in the reverse order.

Batteries
NOTE! Wear safety goggles when working with
batteries.
Removal
1. Detach the seat lift cover and chassis cover,
see page 8.
NOTE! Be careful when removing the chassis
cover. A chassis equipped with lights has the
wiring for its rear lights fastened to the electronics.

2. Switch off the power using the control panel.
3. Set the main fuse to the “OFF” position,
see fig. 10.
4. Block the front edge of the seat up, loosen the
seat lift’s base by loosening the lock nut,
see fig. 11. Take note of the design of the
base with an eye towards the future
remounting. Carefully lower the seat forward.
5. Loosen the battery connections. The positive
terminals first, and thereafter the negative
terminals.
6. In order to gain access to the battery more
easily, the electrical connections for the drive
motor, magnetic brake, lights and brake
release sensor can be loosened. Note the
placement of the cables with an eye towards
future remounting.
7. Lift the batteries out.
Install
1. Seat your two new batteries. The battery
terminals must be located towards the rear.
2. Mount the battery connections, first the
negative terminals and thereafter the positive
terminals.
3. Mount the electrical connections for the drive
motor, magnetic brake, lights and brake
release sensor if they have been
disconnected earlier.
4. Carefully elevate the seat upwards again,
mount the base and retighten the lock nut.

304103-99-0 if the wheel is tight, see fig. 13.
Fitting
1. Check the axle and rim for any damage. If
necessary, you should clean these parts of dirt
and rust. If any parts are damaged, they
should be replaced.
2. Check that the key fits solidly in the keyway of
the axle. If necessary, install the new key and
check for fit.
3. Lubricate the shaft with a thin layer of copper
paste (Würth 0893800x, Art. no.: 1820540).
Warning! Other types of bolts or washers are not
to be used..
Warning! Do not use any other type of thread lock.
Warning! Do not use any type of lubrication in the
threaded hole in the axle or on the bolt.
If necessary, you should clean these parts.
4. Fit the wheel onto the axle. The use of hand
force only is preferred, but, if need be,
carefully use a rubber mallet, whose head
diameter is no less than 1.5 inches (38 mm), to
ensure that the rim is fully seated upon the motor.
NB! Hitting too hard with a rubber mallet could
cause damage to the gear.
5. Put the washers (2 and 3) onto the bolt (4) and
tighten the wheel, see fig. 14.
Use a torque wrench to tighten the bolt to
18 ft-Ibs. Install the hub cap (6), see Fig. 14.
NB! The bolt must be used once only. Removed
bolt is not allowed to be refitted.

Circuit breaker and fuses
Resetting the circuit breaker
The circuit breaker also acts as a battery isolator,
but is usually referred to as the circuit breaker.
You will not normally need to change the circuit
breaker, as you can reset it when it has tripped. It
is located on the underside of the chassis, over the
right rear wheel, see fig. 41. The circuit breaker is
protected from dirt and water by a rubber lip, which
can easily be folded back.
NB! A tripped circuit breaker often means that
there is a serious electrical fault. Check the cause
thoroughly before you reset the circuit breaker.
Changing the circuit breaker
1. Detach the seat lift and chassis covers,
see page 8.
2. Switch off the power using the control panel.
3. Put the circuit breaker in the “OFF” position,
see fig. 41.
4. Disconnect the battery positive lead, which is
between the battery and the circuit breaker.
5. Remove the circuit breaker by removing the
two screws, see fig. 42.
NB! Note the orientation of the circuit breaker.
The ON/OFF positions must agree with the label.
6. Disconnect the cables from the circuit breaker
by loosening the screws, see fig. 43.
7. Connect the cables to the new circuit breaker.
Put the circuit breaker in the “OFF” position.
NB! Check that the cables are fully secure.
8. Attach the new circuit breaker with the two
screws, see fig. 42.
NB! Check the orientation of the circuit breaker.
The ON/OFF positions must agree with the label.
9. Reconnect the battery positive lead.
10. Mount the seat lift and chassis covers,
see page 8.
11. Put the circuit breaker in the “ON” position,
see fig. 46.
