Front Wheel Installation - Procedure 1
Note:
The machine will remain stable, even after one wheel has been removed. However, for a safer
working environment, it is recommended to support the unit with wooden blocks or a jack.
1) Install the new wheel on the machine chassis in the same position as that of the previously-removed
wheel. Make sure it is correctly positioned, parallel to the other front wheel.
2.) Lift the transverse arm (wheel position bar) and secure it into position by re-attaching the spring
washer to the central locking pin (refer to
Figure 8-92 "Releasing the Spring Washer from the Center
of the Transverse Arm" on page 8-109
).
3.) Return the four bolts (three wrench bolts and one Allen bolt - removed in
step 3
on page 8-109) and
make sure that wheel is secured firmly to the chassis (see
Figure 8-93 "Front Wheel Bolted to
Chassis" on page 8-109
).
4.) Return the Vivid 3N front cover, as described in
8-2-3-4 "Front Cover Installation Procedure" on page
8-6
.

Front Wheel Installation - Procedure 2
WARNING: When performing this procedure, the machine must be safely supported on two
wooden blocks (or on a jack capable of supporting the weight of the machine). Do not lean on
the machine, or leave it unattended without support, when the wheels have been removed.
Always remove and replace one wheel at a time, before attempting to remove the second wheel.
1) Having removed one wheel from the machine chassis (as described in
8-6-8-4 "Front Wheel
Removal - Procedure 2" on page 8-110
), install one of the new wheels in its place, ensuring that the
wheel is correctly positioned.
Install the four bolts (three wrench bolts and one Allen bolt removed in
step 6
on page 8-111 [refer
to
Figure 8-96 "Front Wheel Bolted to Chassis" on page 8-111
]), making sure that the wheel is
secured firmly to the chassis.
2) Having removed the second wheel from the machine chassis (as described in
8-6-8-4 "Front Wheel
Removal - Procedure 2" on page 8-110
), install the other new wheel in its place, ensuring that the
new wheel is correctly positioned, parallel to the other new front wheel.
Install the four bolts (three wrench bolts and one Allen bolt removed in
step 6
on page 8-111 [refer
to
Figure 8-96 "Front Wheel Bolted to Chassis" on page 8-111
]), making sure that each wheel is
secured firmly to the chassis.
3.) Install the new transverse arm (wheel position bar) by hooking it onto the central locking pin located
above the brake pedal and securing it into position (attach the spring washer [supplied] to the
central pin - refer to
Figure 8-95 "Removing the Transverse Arm" on page 8-111
and
Figure 8-92
"Releasing the Spring Washer from the Center of the Transverse Arm" on page 8-109
).
4.) Lift the transverse arm
upwards
and attach a new locking spring washer (supplied) to the underside
of each end of the transverse arm. Refer to
step 4
on page 8-110 and
Figure 8-94 "Releasing the
Spring Washer from the End of the Transverse Arm" on page 8-110
.
5.) Return the Vivid 3N front cover, as described in
