Lift Assembly
1. Attach the base of the Cylinder Support Column Assembly with four 3/8” – 16 x 4-1/2” hex head
bolts protruding from the support column, as shown in figure 1. Secure the base with four 3/8” Flat
washers and four 3/8” acorn nuts, torque to 20 ft-lb.
2. Install the Pressure Wheel and the Pressure Wheel Guard using a 3/8”x 5 ½” hex head bolt, Two
3/8” flat washers, a 3/8” lock washer, and a 3/8” acorn nut.
3. Mount the valve to the valve bracket on the base as shown in figure 1. Use the brass hardware
supplied with the valve.
4. Remove the upper valve handle knob from the valve handle and slide the valve handle through the
handle valve bracket. Match the flat on the valve post to the flat on the inside of the valve handle
sleeve and slide the valve handle onto the valve post. Replace the upper valve handle knob on the
valve handle.
NOTE: The two-piece collar on the valve handle and slide the valve handle in place and may need to
be repositioned. To move the collar, loosen the screws in the collar using a 7/64” hex key wrench.
Move the collar so that it is just below the valve handle bracket and retighten the screws. See Figure 1.
4. Screw the Leveler Pad into the base assembly as shown in figure 4.
5. Bolt the lift to the anchors in the deck using two 1” diameter by 4” length acme bolts as shown in
figure 5. Do not completely tighten the 1” diameter acme bolts at this time.
6. Attach the Seat back to the Seat Frame with four 5/16” – 18x3/4” Button head screws torqued to 11
ft-lb, as shown in figure 1.
7. Attach the Seat bottom to the Seat Pole by using two 5/16” – 18 x 1” Button Head screws. First
install a 5/16” – 18 x 1” button head screw and insert this through one of the two front holes of the
Seat arm plate, then through the seat frame and then finally set the screw into the seat bottom as
shown in figure 1, loosely.
8. After the Seat assembly has been secured with the two front 5/16” - 18 x 1” Button head screws,
insert two 5/16” – 18 x 1” Button head screws through two 5/16” flat washers and then through the
Seat belt grommets and into the Seat assembly tightening all 5/16” - 18 x 1” Button head screws to
11 lb-ft at this time, as shown in figure 1.
9. Level the lift front to back, if necessary, by using donut shims between the base stand and each
anchor, and adjusting the Leveler Pad by screwing the Pad in or out. The donut shims can be used
individually or in combination to level the lift. The donut shims can be used above the anchor base
or below as shown in figure 5 to prevent the acme bolts from bottoming out in the anchors.
10. Check that the cylinder if perpendicular to the deck in all directions with a carpenters’ level.
Adjust the Leveler Pad or change donut shims at each anchor to level the lift. If the lift is not
installed level and perpendicular, it may lower the lifting capacity, reduce the operational life of the
lift or void the warranty.
