Lazer Z units with SN 352,000 – 509,999 (Lazer Z XP, Lazer Z XS, and Lazer Z
510,000 units skip to section 3.2.15):
3.2.9 When installing the Ultra Vac 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.
3.2.10 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.
3.2.11 Install the mount weldment (Item 9) loosely to the rear of the machine using the
two bolts and nuts removed in section 3.2.10.
3.2.12 Jack the rear of the unit up and safely support it on jack stands. Remove the rear
wheels.
POTENTIAL HAZARD
♦ Relying solely on mechanical or hydraulic jacks to
support the mower could be dangerous.
WHAT CAN HAPPEN
♦ The mechanical or hydraulic jacks may not be enough
support or may malfunction allowing the unit to fall,
which could cause injury.
HOW TO AVOID THE HAZARD
♦ DO NOT rely solely on mechanical or hydraulic jacks
for support. Use adequate jack stands or equivalent
support.
3.2.13 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.
Secure using (8) 3/8-16 x 1.00 bolts (Item 23), (8) 3/8 spring disk washers (Item
25) and (8) 3/8-16 whizlock nuts (Item 24). Make sure that the raised portion of
the spring disk washer faces the head of the bolt.
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 Numbers 440,000
through 509,999 will have a captured bolt in this position. See Figure 2.
NOTE: On 52 and 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.
