■ ASSEMBLY PROCEDURE
9. Per fig. 9, attach the windshield to the windshield support
using four 5/16-18 x 1 3/4” long flat head bolts, four 5/16”
steel washers, and four 5/16” locknuts. Be sure to sandwich
the hinge spacer block under the hinge. Do not tighten the
bolts at this time.
10. Engage the two lower latches onto the pins so that two
audible clicks can be heard ensuring that the latches are
fully seated. Push the windshield down so that it is sealed to
the hood. Orient the latch so that it is in line with the
windshield tubing similar to what is shown in fig. 8.2, tighten
the two bolts making sure that the sides of the windshield
are sealed as well as the hood. Tighten the pin at this time.
Once the bottom of the windshield is adjusted, tighten the
hinge bolts. Caution: use care when tightening any flat head
screw in countersunk holes in plastic components to avoid
cracking. Torque to 7 ft.-lbs. max.
11. After the windshield is properly adjusted, release the
two bottom latches and open the windshield. Attach the two
gas springs so that the thin rod end is fastened to the ball
stud on the front leg.
12. Per fig. 12, attach a length of 1/2” weatherseal along the
top of the ROPS bar on both sides between the windshield
support and the rear roof support. Be sure that the ROPS is
clean and dry and at room temperature before adhering the
weatherseal.
13. Using a screwdriver, puncture the headliner at each
hole location from the inside out to allow the bolt to pass
through. Attach the roof to the supports using ten 5/16-18 x
1” button head bolts, twenty 5/16” steel washers, ten 5/16”
nylon washers, and ten 5/16” lock nuts. Note: there will be
two holes left open at this time that are shown in fig. 14.1.
14. Per figures 14.1 and 14.2, install the bolt for the door
stop cable (one per side of roof) as shown. Use the following
hardware per side: one 5/16-18 x 1 1/4” long button head
bolt, two steel washers, one plastic washer, and two
locknuts. With the roof oriented as shown (with the headliner
down), install one steel washer and one plastic washer on to
the bolt. Feed the bolt through the sheet metal and through
the foam headliner. Install the second steel washer and one
locknut. Tighten the locknut. Install one end of the door stop
cable onto the bolt. Install the second locknut, but do not
tighten it up against the door stop cable. There should be a
small intentional gap so the cable can rotate freely. Repeat
in the last remaining roof hole.

■ ASSEMBLY PROCEDURE
15. Apply Velcro to the rear roof support above the snaps to
match the rear panel. Velcro should only be applied to clean
dry surfaces at room temperature. Apply Velcro down each
rear leg as well to match the rear panel. A strip of Velcro
should also be applied along the outside lip across the back
of the seat. Snap the rear panel into place and secure the
perimeter to the Velcro.
16. Per fig. 16, install the supplied ROPS decal to the inside
surface of the rear driver’s side ROPS tubing as shown.
Apply to a clean, dry surface at room temperature.
17. Apply grease to the door hinge pins.
18. Insert the hinge pins on the doors into the sleeves on
the vehicle. Slowly close the door. Adjust the striker pin
vertically in the slot if necessary. If contacting the top or
bottom of the striker pin, adjust the pin in the slot to avoid
excessive pin wear. The latch can also be moved forward
and backwards to catch on the center of the pin. Two
audible clicks should be heard when the latch is engaged
fully. If more adjustment is required, loosen the hinge pins
and adjust them as well. The hinge pins should be in-line
with each other when a straight edge is placed against the
back of them.
19. Connect the free end of the door stop cable to the door.
Leave it slightly loose so that the cable may rotate freely.

CARE AND MAINTENANCE
(IMPORTANT: Be sure to leave this page with the owner once installation is complete)
Check and tighten hardware after 20 hours of operation.
Periodically inspect and tighten hardware for the remainder of the unit’s service life.
Keep the enclosure components clean in order to prevent dust and dirt from forming an unattractive
film. The life of your windows, doors, and roof panels depends upon following these care proce-
dures:
WINDSHIELD:
1) NEVER USE AN ALCOHOL-BASED PRODUCT FOR CLEANING PLASTIC WINDOWS. Many
brand-name glass cleaners contain alcohol that will result in deterioration of the windows.
2) Wash with a mild soap or detergent using your bare hands to free or dislodge any caked-on dirt
or other foreign particles.
3) A soft, grit-free cloth, sponge, or chamois may be used but only as a means of carrying water to
the windows.
4) The interior should be lightly dusted (NOT WIPED) with a clean soft cloth or chamois. The cloth
or chamois should be kept free of grit by frequent rinsing in clean water.
5) Grease and oil may be removed with kerosene.
DOORS AND REAR PANELS:
1) NEVER USE AN ABRASIVE DETERGENT/VEHICLE CLEANER OR A WIRE BRISTLED
BRUSH. Do not use any CITRUS BASED CLEANERS such as orange or lemon. Use of these
products will cause the plastic to become permanently damaged.
2) Clean the enclosure surfaces thoroughly with warm soapy water and a COTTON cloth or cham-
ois. Be sure to use mild soap, specifically a dish liquid or equivalent. Clean in a light circular
motion for best results.
This manual is the property of the owner.
Be sure to leave with the owner when installation is complete.
