Exmark ULTRAVAC QUICK DUMP SYSTEM Setup Instructions page 7

Lazer Z Units with Serial Number
352,000–509,999:
Note: For units with ROPS installed, temporarily
remove the ROPS to allow for installation of the
UltraVac. Retain the hardware for re-use.
Important: For Units without a ROPS, a free
retrofit kit is available and should be installed before
using the UltraVac; contact your Authorized Service
Dealer for details.
1. When installing the UltraVac onto a liquid-cooled
Lazer Z, the rear bumper plate must be removed.
Remove rear bumper plate. Reattach the lower side
bumper bars to the vertical "HOT" engine guard
shield using two of the original screws, washers and
whizlock nuts removed from the bumper plate.
2. Remove the lower two screws holding the clutch
guard plate ("HOT" engine guard on liquid–cooled
units) to the rear frame of the Lazer Z unit.
3. Install the mount weldment (item 9) loosely to the
rear of the machine using the two bolts and nuts
removed in step 1.
4. Jack the rear of the unit up and safely support it on
jack stands. Remove the rear wheels.
CAUTION
Raising the mower deck for service or
maintenance relying solely on mechanical
or hydraulic jacks could be dangerous. The
mechanical or hydraulic jacks may not be
enough support or may malfunction allowing
the unit to fall, which could cause injury.
Do Not rely solely on mechanical or hydraulic
jacks for support. Use adequate jack stands or
equivalent support.
5. Install the right and left hand frame brackets (items
14 and 15) loosely to the mount weldment and wheel
channels on both sides of the Lazer Z frame. The
flanges on the side plates should face in towards the
unit to provide the maximum tire clearance.
6. Secure using eight 3/8-16 x 1 1/4 inch bolts (item
23), eight 3/8 spring disc washers (item 25) and eight
3/8-16 inch whizlock nuts (item 24). Make sure that
the raised portion of the spring disc washer faces
the head of the bolt.
For Units with a ROPS
1. Do Not install this screw at this time.
Note: On units with a ROPS installed, the lower
front screw that attaches to the wheel motor channel
must be left uninstalled. Units with Serial Number
440,000 through 509,999 will have a captured bolt in
this position (see Figure 6).
Note: On 60 inch units, the lower bolt on the
wheel channel is best installed by positioning the nut
behind the hole using a deep socket and turning the
bolt through the hole into the nut.
7. Install the ROPS by aligning the three spacers on
each side and taping with masking tape to the rear
frame as shown in Figure 7.
1. Lower roll bar tubes
2. Align spacers and tape to
frame.
3. Raise rear of unit here and
support with jack stands.
4. Wheel nuts
8. Align lower roll bar tubes along wheel motor
channels as shown in Figure 7.
